Title: Tiangong - Chinese Space Station
Post by: Phillip Clark on 09/23/2011 07:25 am
Some discussions which I started on the Tiangong 1 thread were mis-interpreted as relating to Tianging 1 rather than the future module space station which the Chinese are planning, so I am starting a new thread here in the hope of preventing such confusion.

We all know by now that around 2020 the Chinese hope to start the construction of a modular space station, which could be their equivalent of Mir.

We know that there will be a core module and at least two permanent/long-term modules of a similar size - around 20-25 tonnes - launched by the CZ-5 vehicle.

A Shenzhou is shown at the front longitudinal port, having taken three people (I assume) to the station.   At the back there is a cargo freighter, derived from the Tiangong module.

This configuration appears in both still images like the one which I am attaching and videos showing the assembly of the station.

The front of the core module appears to have five docking ports.   The front longitudinal one is occupied by a Shenzhou - other than when a new module does the preliminary docking - and the two radial ports are occupied by the plug-on modules.   What about the zenith and nadir ports?   I have never seen any depictions of these being occupied by either a Shenzhou or a plug-on module.

On Mir the standard practive was to vacate the rear longitudinal port to allow a new Soyuz crew to dock there and when the older crew and Soyuz returned to Earth the new Soyuz would move to the front port, allowing the rear port to be used once more by Progress cargo freighters.   (Pause: yes, I know that there were exceptions, but I am talking in overall terms here.)

Therefore it would be reasonable that if the Chinese station were to be permanently occupied like Mir a used Tiangong-class module would be discarded from the rear port and the new Shenzhou docked there, and be relocated after the original crew returns to Earth.   If the Chinese go for six months residencies then one Tiangong cargo freighter should be enough to keep them supplied.

So, why the zenith and nadir docking ports at the front of the core module?   Maybe one could be used as an EVA hatch - but then again the Shenzhou orbital module could be used the same way if the Chinese want to do that.   Maybe the Chinese are keeping open the option of having four radial plug-on modules, as Mir had?

Of course, in the next nine years the design of this station will surely changeand these questions will be answered.

I would suggest specifying the "Chinese" space station in the title.  We already have a modular space station which should be in orbit in 2020, for example.  Also, Bieglow may have a modular space station in orbit by then, and so on...

Since this section is for Chinese launches and space programmes I thought people would take it for granted that I meant a Chinese module space station.

Thank you for posting these pictures.

I had seen the display picture before, but since a similar display showed a Shenzhou with solar panels docked at the smaller module of Tiangong 1, I wonder about their accuracy.

I had not seen to second picture before at all.

Deviating slightly from the title (is there a way to amend the title to "The Chinese Modular Space Station - circa 2020" to avoid confusion?), what can we look forward to in the Chinese programme?

Since Tiangong 1 will be hosting two crews next year then I assume that its operating lifetime wll be around 12-18 months.   If the real future role of Tiangong is to to be a cargo freighter then you don't need multi-year operating times, as we saw with Salyuts 6/7.   Six-nine months for each freighter would be reasonable, depending upon the stay times of the crews on te modular station.

On this basis, I would assume that Tiangongs 2 and 3 will be very much like Tiangong 1, launched at intervals of around 2-3 years.   Maybe extending the in-orbit stay of the crews, varying experiments, gaining more EVA experience perhaps.

What would be nice - and it would need a redesign of Tiangong as we see it now - would be for Tiangong 3 to have a second docking port and then host a test flight of the cargo freighter version while there's a crew on board.

One element of a space station programme does seem to be missing from the Chinese discussions.   From what has been published the Chinese plan to go from the Tiangong-based spacelab to the modular space station, without having a Salyut 6/7 equivalent.   This is surprising since the CZ-5 will be available for the launch of such a 20-25 tonnes station from te middle of this decade.

Of course, it is possible that the Chinese are planning such a mission after Tiangong 3 but they just aren't talking about it yet.

AFAIK, Tiangong-3 is planned to be redesigned to have two docking ports. (I have read this somewhere, but forgot where I read it. Sorry.)

I have just come across the attached illustration at the following web site:

http://english.people.com.cn/102775/202988/index.html

This shows a Shenzhou at both the front and rear longitudinal ports of the core module, one apparently at the nadir port, a Tiangong (cargo freighter variant?) and the zenith port and the two experiment modules, approximately the same size as the core module.

I don't think I have seen this specific configuration before.   Of course, if we consider the three large modules (core and two experiment modules) as fixed, then the Shenzhous and Tiangongs can go anywhere!

@ Phillip Clark,

Depending on the accuracy of this illustration, TG-3's experimental modules look like their TG-1 heritage designs (OML at least).  That picture seems to have a single SZ crew ferry and two SZ cargo ships (one on core aft and one on node nadir).

Of course, a lot can change in a decade.

I have always considered the experimental modules to be similar to Tiangong 1 but with a longer narrow-diameter section and probably with the propulsion system relocated to the rear of the large diameter section.   Maybe they are simply variants of the core module's design?   

Why have a cargo version of Shenzhou when Tiangong will do the job?   I am wondering whether the picture that I posted is primarily a fiction and that the original pictures of the modular space station from 2007-2008 are the accurate ones.

Could the spare ports be for experimental Luna landers?

Or a space tug

The potential of the Chinese space program over the next few decades is incredible = total goverment control combined with a GDP bigger than America and growing.

http://www.economist.com/node/21542155

It's estimated that China's GDP will reach the US level by 2017 so by the time this modular space station is finished in 2020 China will be comfortably the richest country in the world. Nasa has put off the US return to the moon until the end of the 2020s. By that time, will the US be able to catch up with China who plan to be on the moon by 2025?

Chinese don't invent things. They copy it and make it from cheap materials. That station is a copy from old Russian technology. Although being an European, I think the US can top the Chinese easily just by constantly developing new tech AND keeping it a secret. This advice serves for space exploration and for your crappy cars.

That is a viable strategy and it has been proven to work (i.e. Microsoft).  The real advantage for the Chinese is their long-term planning and constancy.

You have no idea what's going on in China currently. You're phrase is full of wrong estimates. Simply check their university output of new engineers or their new high mark of new patents and you will see in which direction the Chinese economy is going.

Remember that China is not Hong Kong or Shanghai. It is a vast country where most people worked on farms 10 years ago.

All I see is tech copied from Russians. They have a lot of money, they are starting to outsource tech outside (I was asked to develop a cheap auto focus lenses 2y ago) but the general feeling is that they have too much cash in hand to bother developing on their own. I've worked with Chinese engineers and believe me that they have a very long way to go.

One of the worst thing about Chinese is that they are not assertive. You ask a Yes or No question and the guy starts talking about something else. That is so profound that even most their languages don't have past/present/future conjugation of verbs. I could give you examples all night, but the bottom line is that their peculiar way of thinking does not make a good engineer.
I had several conversations with Chinese engineers and it was very frustrating. Oh, and one of them tried to sell me an orphan, but that's another thing about them: money 1st, money 1st, money 1st.

All the material I have seen appears to indicate that there will be only two modules docked gto the core, but there appear to be four lateral docking ports.  Is there any suggestion that they will be occupied at some stage?  It would push the final mass from 60 tonnes to ~100, more with Shenzhou and the supply craft attached

Does anyone who can read original Chinese material clarify this?   Of course, eight years into the future, probably the Chinese planners themselves do not know!

The original announced completion year was 2020–2022. I think the core module should be launched some time around 2018. And I think the station weren't be end up only 60 tons. There are two unused docking ports, other "friendly" countries may contribute their own modules to the station as well.

Won't Tiangong-3 serve as the core module?
  I'm taking my info from Wikipedia.  Tiangong-3 will have the size and
mass of each of the modules of the planned Modular Chinese Space Station. And according to Wikipedia, Tiangong-3 will be launched
around 2015. 
So for at least five years it appears, Tiangong-3 will orbit without additional modules.
Leaves me wondering what the Chinese manned psace program plans to
do between 2015 and 2020?
Send an upgraded Shenzhou to circle the Moon?
Send one to a NEO asteroid?

Title: Re: Chinese Modular Space Station - circa 2020
Post by: Dalhousie on 06/26/2012 09:38 pm
How much power is required depends on the experiments planned, some are more power hungry than others. 

Basic life support isn't that demanding, about 1 kw per person, with some reycling of oxygen and water.  To support three people you only need about a 7 kW array

Also remember the steady improvments in solar panel efficiency, now over 30% (over 40% in the lab). I don't know what efficiency those on Mir were but given the construction period I would guess about 15%

I think the unknown here is launcher development.

The ISS was hobbled by utilising the Space Shuttle to launch many of its components.

I think the chinese will aim for a larger station (by volume) with less modules launched by larger rockets.

Maybe the only launcher from USA perspective - but I thought the Russian Proton had a marginally larger capacity and was not constrained by the Cargo Bay size.

After all it launched some ISS components.

Assembly on ground in larger volume modules would have been cheaper than multiple modules which means multiple projects / launches and would have enabled the ISS to be completed sooner.

Maybe this way the ISS Centrifuge Accommodations Module would have made it to space.

As I said - it will be interesting to see the Chinese strategy unfold.
Title: Re: Chinese Modular Space Station - circa 2020
Post by: Phillip Clark on 06/27/2012 07:33 am
Perhaps Tiangong 3 will be prepresentative of the size, mass of the modular station's core module, but I would expect this to be more akin to a "Salyut 6/7" station rather than a "Mir" core module.

This would mean that the Chinese could get basic experience with Tiangong 1 and Tiangong 2 (using a modificed TG 1 back-up module?), with Tiangong 3 allowing longer piloted missions with the cargo variant of Tiangong annually (?) taking supplies to the station.

Remember that the schedule for Tiangong 3 (in particular) and the modular station are dependent upon the early success of the CZ-5 class launch vehicles.   Would the Chinese put Tiangong 3 on the very first CZ-5?

From page 86 of the August 2012 ESA Bulletin

http://esamultimedia.esa.int/multimedia/publications/ESA-Bulletin-151/offline/download.pdf

CREW TRANSPORTATION

International Berthing and Docking Mechanism (IBDM) IBDM dynamic testing was completed at SIRRIS in Leuven, Belgium. The results confirmed the feasibility of a design compatible with both NASA and Russian designs.

International Docking System Standard (IDSS)

Docking standardisation discussions continued with representatives of the Chinese Manned Space Engineering Office (CMSEO) at ESTEC in May. The Chinese have shown interest in discussing possible adaptations of their docking system to an international standard and to the joint definition of a new large-diameter mechanism, capable (like the IBDM) of docking and berthing, for the permanent connection of major modules of their Space Station. The exchanges on the development of docking systems with the Chinese showed that also China identified the need for a docking system that could work for space vehicles of various masses and deliver moderate impact loads.

An International Docking Systems Workshop at ESTEC in May involved about 30 experts (from USA, Europe, Canada, Russia, China and Japan), bringing together for the first time the IDSS partners from the ISS countries and new participants, offering an opportunity to enlarge the docking standardisation discussions to a new set of international partners (for example, China).

The need for a standard docking interface was reconfirmed and the design of ESA’s IBDM system appeared as a very promising candidate for such a standard. ESA was asked to organise a follow-up workshop at the IAF Conference in October. Discussions with NASA and the Canadian Space Agency looked at the possible joint development of a new docking system based on the IBDM.

Sounds like ESA is trying to give themselves much more credit than they deserve. Their "International Berthing Docking Mechanism" (IBDM) is simply an implementation of the International Docking System Standard (IDSS).

The Chinese have had LOX/LH2 upper stage engines for years now. The Russians still do not even though they developed one for the Indians which is supposed to be used in Angara.

If it is cheaper to buy a license rather than doing all the R&D from scratch why bother? Their technological gap is so wide that currently this is the best way of proceeding. Eventually they will start doing more things on their own.

Talk about cultural differences blocking R&D development are just that: talk. I have heard the same thing applied to Japan and South Korea. They have been proven wrong time and again. China has enough skilled people and resources to pull it off. They import a lot of tech, but so did Russia between WWI and WWII. They still managed to put Sputnik, Gagarin and Leonov in space.

Jim, I think he is thinking Skylab as the method of assembling a station. The Saturn V was able to put very large and very heavy components into orbit. If the equivillant of Skylab was to be assembled in orbit by shuttle, how many shuttle flights and EVAs would it have required? Whatever your answer is, I'm sure it would have required more flights and EVA time, costing more, while increasing risk.

There are some interesting statements about the Chinese Space Station plans in this blog/report by Clive Simpson, who was previously editor of 'Spaceflight'.

http://simcomm.blogspot.com/

Some of these comments were not previously know to me, and I don't think they had been explicitly stated by China:-

- The Chinese space station is expected to be completed and fully operational around 2020.

- The Space Station will conduct long-term man-tended operations with the nominal status of three crew who will alternate every half year

- The construction phase would see intermittent visits and stays depending on mission requirements and that some EVAs would be performed

- There will also be a cargo re-supply ship sent up to the orbiting complex between one and two times a year

论坛上,中国载人航天工程总师周建平介绍了空间站建设总体构想:在轨运营10年以上,基本构型为T字型,由3个22吨级舱段组成,核心舱居中,实验舱Ⅰ和实验舱Ⅱ分别连接于两侧。核心舱前端设两个对接口,接纳载人飞船对接和停靠;后端设后向对接口,作为货运飞船补给端口。站上设气闸舱用于航天员出舱,配置大小两个机械臂用于辅助对接、补给、出舱和科学实验。在空间站运营阶段,还将发射第二个核心舱进行前向对接,最终整站形成十字构型,并具备进一步的舱段扩展能力。
some statements of future modular space station circa 2020:
the space station will have two mechanical arms
baseline configuration: core module + experiment module 1 + experiment module 2
final configuration: core module + experiment module 1 + experiment module 2 + core module 2 (china version MIR?)

That notes,

The green technologies to be applied in the station will raise its recycling rate and reduce its reliance on input from the ground.

For example, waste water and urine will be used to extract oxygen, and carbon dioxide and other human waste will also be recycled, Zhou said.

Which, interpreted optimistically, sounds like working in the direction of a DSH ECLSS.

The first image has radiators, and some of the 'solar panels' on the others appear to be mostly the same size, shape and location as those radiators; looks like they've just been translated from design to CGI incorrectly, like those images of Tiangong being docked with at the wrong end.

Assembly on ground in larger volume modules would have been cheaper than multiple modules which means multiple projects / launches and would have enabled the ISS to be completed sooner.

Unsubstantiated and basically wrong.  There is no data to support your claim.

There is no data to prove him wrong either. Common sense says that if two of anything can been combined into 1, it is faster and more economical.

Smooth launch for Shenzhou X crew on China's longest manned space mission
Stephen Chen at Jiuquan Satellite Launch Centre, Inner Mongolia
Wednesday, 12 June, 2013 [Updated: 1:55PM]

<snip>

But the future of China's largest space launch centre [Jiuquan] is under a cloud, because it will soon be eclipsed by an even bigger one in Wenchang , Hainan , which is nearing completion.

Lu Jinron, the chief engineer at Jiuquan, said Wenchang would definitely have an impact on Jiuquan. Launches for the construction of a space laboratory would still be carried out by Jiuquan, but Wenchang would take over the heavy lifting job for China's ambitious space station project, scheduled for completion by 2020, he said.

"Jiuquan will still be responsible for all manned launches," he said. "We have more experience. We also have sunnier weather. We can provide absolute safety to the astronauts."

I noted that the animations for Tiangong 2 suggesting that refuelling might come along while the space lab is unmanned, thus meaning that - like Tiangong 1 - only one docking port is required on the lab.   So, Tiangong 2 will not be based upon the modular station's core module or an experimental module.

Also it was specifically said that the module station should be assembled by 2020, suggesting that launches might take place in the 2018-2019 timescale.   Will a crew be launched before the automatic dockings of the two experiment modules?   I would expect that the first module will docking on the front longitudinal port and then be relocated to a side port shortly before the second module is launched: that way the station remains symmetrical for most of the time.

Finally, the Chinese are clearly thinking of the option of further expanding the station after the initial operations by docking a second core module and further experiment modules.   All very interesting to me.

But why to develop a second generation station with only a docking port? The Shenzhou has a limited cargo capacity and even if TG-2 is launched with a major cargo of supplies on board, the objectives of the following manned missions would be very limited in terms of prolonged presences in orbit in advance of the modular station.

Some folks are not convinced the ISS is in the wrong orbit for Lunar and Mars missions. The ISS's orbital inclination of 51.65 degrees is about the same as Skylab's 50 degree orbital inclination, and different than Tiangong-1's 42.78 degrees orbital inclination.

The orbit of the International Space Station is a bit of a compromise for various LEO and beyond LEO missions, but on the plus side it periodically flies over the major launch sites of the world which can provide redundant launch access to the ISS.


Manned flight around Moon considered By Jonathan Amos Science correspondent, BBC News   October 11, 2010
At: http://www.bbc.co.uk/news/science-environment-11304559

"'We need the courage of starting a new era,' Europe's director of human spaceflight, Simonetta Di Pippo, told BBC News.

'The idea is to ascend to the space station the various elements of the mission, and then try to assemble the spacecraft at the ISS, and go from the orbit of the space station to the Moon.'"

And, "If humans ever do go to asteroids or Mars, the scale of the infrastructure needed to complete a safe round trip could not possibly be launched on a single rocket from Earth. It will have to be sent up on multiple flights and joined together in orbit.

Doing this assembly at the ISS means it can be overseen by astronauts with ready access to tools if needed."

Soyuz to the Moon?   by Jeff Foust    August 2, 2004
At: http://www.thespacereview.com/article/199/1

"Once the module and upper stage were in orbit, a Soyuz spacecraft that had completed its half-year stay at the ISS would undock from the station and dock with the logistics module. The upper stage attached to the other end of the logistics module then fires, sending the complete spacecraft on a free-return circumlunar trajectory."



In considering the previously noted illustration, perhaps there is the possibility of China eventually staging cargo and human Lunar missions from its future Modular Space Station.

"China expects to complete space station by 2023

China will complete its first space station within 10 years and be able to send crews of up to six people for short-term missions, according to the 64th International Astronautical Congress.
...
"Room in the station will be no less than 60 square meters, which is enough for astronauts to move freely," said Xu Dazhe, general manager of China Aerospace Science and Technology Corp, at the five-day event that began on Monday in Beijing.

He said the station will also be able to support three astronauts on long-term missions.
...
According to China Manned Space Engineering Office, the space station will consist of three capsules with a cargo shuttle to transport supplies.

The station's core module will be 18.1 meters in length and will weigh 20 to 22 metric tons. The space station will also consist of two self-contained laboratories.

Wang Zhaoyao, director of China Manned Space Agency, said astronauts will be able to make long-term missions in orbit and conduct technical tests.

But more research and development will be needed to complete the space station, Zhou Jianping, chief designer of the manned space program, told Chinanews on Monday. He said China will be able to launch the planned space station in 10 years."

Dock it to ISS, and then what? Not going to the moon from there, it is at the wrong inclination.

Not so... The delta-V to reach the moon is virtually identical from pretty much ANY inclination in LEO. You just have fewer and tighter launch windows.

This myth that the ISS orbit is a terrible staging point for BLEO needs to die. The most significant difference is the delta-v from launch to that LEO inclination. But once you are in LEO you always at minimum two launch windows to the moon per month.



"The Orbital Piloted Assembly and Experiment Complex (Russian: Орбитальный Пилотируемый Сборочно-Экспериментальный Комплекс, Orbitalnyj Pilotiruiemyj Sboročno-Ekspierimientalnyj Komplieks)[1][2] (ОПСЭК, OPSEK) is a proposed third-generation modular space station in Low Earth orbit. OPSEK would initially consist of modules from the Russian Orbital Segment of the International Space Station (ISS)."

And, "The proposal would use OPSEK to assemble components of manned interplanetary spacecraft destined for Mars, the Moon, and possibly Saturn."

From: Orbital Piloted Assembly and Experiment Complex    Wikipedia
At: http://en.wikipedia.org/wiki/OPSEK



"At the forefront of the talks were Russian plans to replace the ISS with a new manned outpost in low Earth orbit in 2020-2025. However unlike the ISS, which was designed to serve primarily as a research lab, the new station was conceived as an assembly point for missions to the Moon and Mars. Russian and European officials said they hoped that NASA would also be interested in the project."

Blackstar, does this answer your concern about the potential usefulness of the ISS, OPSEK, or the Chinese Modular Space Station - circa 2020 for stacking or staging the elements needed for various Lunar and beyond cislunar missions?

Thanks Lsquirrel. The presentation says the supply ships are called Tianzhou and will be launched by CZ-7. Shenzhou will continue to be launched by CZ-2F. That's the first time I've seen the name Tianzhou mentioned. As Tian Gong means "Heavenly Palace" and  Shen Zhou means "Divine Craft", I take it that Tianzhou means "Heavenly Craft". It also says there are three types of supply ships; pressurised, semi-pressurised and unpressurised.

CZ-5B will be used to launch the three modules. The station will be occupied by three taikonauts for up six months in duration at a time for a continuous human presence. Assembly of the modules is similar to that used by Mir. The station will have regenerative life support and electric propulsion.

Tiangong 2 is being launched to verify refuelling and mid-term habitation technologies. LM-7 and CZ-5B will be first launched on test flights.

For international cooperation opportunities exist for international or jointly developed laboratory modules, international spacecraft visits, joint training and flights of astronauts, space rescue, and international payloads and experiments.

I have corrected some of the translations above in italics.  ;)

Personally I found the names to be, um, only roughly average - there's too much references to the heavens in the naming scheme! And they have recycled the Tiangong name to the space station - this must be very confusing to people all around the world since there is a Tiangong-2 already coming soon...

Oh well it's at least 5 years away from launch anyway, perhaps they will come up with another name by then (remember that Salyut 1 almost became Zarya 1!).  ::)

Meanwhile the CMSE office has also got a new logo.  :)

Having does not mean that it has to be a primary drive source.  Having and testing one in space is still science until capabilities are increased above 720 mN.  Also, isn't the benefit of EM in that small but long duration thrust has benefits?

"Yang Juan, Professor of Propulsion Theory and Engineering of Aeronautics and Astronautics at the Northwestern Polytechnic University in Xi’an published last year in the academic journal Acta Physica Sinica about her success in generating thrust measurements from a Microwave resonance based device. In 2010 Yuan quantified the amount of thrust that could be produced, and stated that the team was getting positive experimental results. Their latest paper describes their latest thruster and gives the test results in details, showing that with a couple of kilowatts of power they can produce 720 mN (about 72 grams) of thrust."

If it is used in continuous thrust mode, exactly to cancel the drag, it would not affect the environment at all. But, having a continuous thrust SEP engine running for years would be quite an achievement. Weight and size might not matter much for this application, and it would be relatively tiny. We calculated that to counteract the drag of the ISS you needed around 250mN of thrust. It will depend on the solar panels drag, of course, but I would guess that if they do 100mN with the ability to throttle down, it will be more than fine. Girded ion engines technology would be out, though.

Is there any difference using an ion engine in LEO compared to higher orbits? There's a bit of free oxygen floating around in LEO (where you get that drag) and I wonder if that creates any problems with the emitter or charged particles or anything like that.

Typical grided or Hall ion engines use argon or xenon; IIRC, argon will never form an oxide and xenon oxide is really difficult. So, I doubt oxygen is an issue. A greater challenge might be keeping any crew on EVA from touching the high-voltage systems.

Also, *somewhere* on this very forum is presentation on putting an electrodynamic tether on ISS to change its orbital inclination...

It makes little sense at this point to design a station for LEO without SEP - it reduces the mass requirement per year substantially for not a lot of cost.

The EM Drive remains unexplained fringe theory that everything we know about physics says will eventually be explained away in terms of poor testing methodology.  Ion thrusters are COTS flight-proven hardware.  Electrodynamic tethers are physically well-modelled but untested tech.  It's a safe bet they're talking about ion thrusters.

It would be best if you didn't engage in speculation about the EM thruster here, especially making such short hand assumptions as it will only probably lead to the thread lurching wildly off topic.

Informative article on this from Space News reporting from the IAC, especially intrigued by the dock able astronomy telescope & their reaching out to the international community for cooperation.

China's Space Station Planners Put out Welcome Mat

Quote
JERUSALEM — China is soliciting international participation in its future manned space station in the form of foreign modules that would attach to the three-module core system, visits by foreign crew-transport vehicles for short stays and the involvement of non-Chinese researchers in placing experiments on the complex, the chief designer of China’s manned space program said Oct. 12.

But he declined to commit to an international orbital docking technology that would facilitate international participation in the Chinese facility.

The Chinese orbital station, consisting of a core module and two experiment-carrying modules, can be expanded to a total of six modules if international partners want to invest in their own components, said Zhou Jianping, chief designer of the China Manned Space Program at the China Manned Space Agency.

Zhou said China plans to launch an astronomy telescope into an orbit near enough to the space station to dock to it for upgrades and servicing. He declined to specify the telescope’s size.

Time to breathe new life into this thread. There have been several updates on the "Novosti kosmonavtiki" forum in the last few weeks (with interesting comments from Konstantin Lantratov, a former NK journalist) :

http://novosti-kosmonavtiki.ru/forum/forum10/topic8751/?PAGEN_1=40

Most notably, a 35-page document (unfortunately, in Chinese) on the space station published by the Chinese Manned Space Agency :
http://cmse.gov.cn/uploadfile/news/uploadfile/201604/20160427104809225.pdf

A short summary of that in English can be found here :
http://www.popsci.com/chinas-space-station-plans-in-powerpoint-closer-look-at-tiangong-3

The name Tiangong-3 used in the summary does not appear to be correct. This was the name of a Tiangong with two docking ports (ala Salyut-6 and Salyut-7) that was cancelled a while ago.

Interesting plans for a Hubble-class space telescope (Xuntian) that will periodically dock with the station for servicing. More here (in Chinese) :

http://www.chinaspaceflight.com/css/Xuntian/Xuntian.html

Yang Liwei recently gave the following launch schedule in a meeting with students :
- core module (Tianhe) : approximately 2018
- first research module (Wentian) : approximately 2020
- second research module (recently renamed Mengtian or "Heavenly Dream") : approximately 2021
- completion of station assembly : 2022

Another source (in Chinese) says assembly will be completed "after 2022" and the Xuntian space telescope will be launched after 2022. It refers to the core module as Tianhe-1 (which implies there will also be a Tianhe-2 at a later stage) :
http://news.xinhuanet.com/politics/2016-04/21/c_1118695895.htm

Finally, a model of the space station is shown at a science and technology exhibition that opened in Beijing on 1 June. Note Wentian with its EVA airlock, very reminiscent of Mir's Kvant-2 module. Lantratov says that prior to the arrival of Wentian, cosmonauts will exit the station via a hatch on the "zenith" side of the docking node (where there is no docking port).

As I understand, the Russians did a complete technology transfer in the 2000's to China on firstly the analog Kurs versions and much more recently the digital Kurs (both Kurs ATV, NA and MM versions). Transfer of the European rendezvous and avionics systems used in the Kurs ATV System was through a MoU and cooperation agreement with ESA.

A couple of queries for which someone might know the answer.

When the names for the components of the Tiangong Complex (as I call the station) appeared, the second plug-on module was given the name Xuntian but the latest data show that the name is actually to be Mangtian, with the free-flying space telescope being Xuntian.   I am wondering whether there has been a genuine name switch for the second module or what there was a bureaucratic blunder which led to the "Xuntian" name being applied to the wrong piece of the Tiangong Complex "kit" when the first details were released and this error simply got repeated in other literature.   

Thoughts anyone?

Next, a query that needs someone who knows the Chinese language well.   China is a predominantly atheist country and therefore the use of "Heavenly" as part of spacecraft names seems to be rather strange.   I am wondering whether what we translate as "heavenly" might convey something like "beyond the atmosphere" (ie, outer space) rather than having religious associations.   Same with "divine" as part of the Shenzhou name.

I would be interested in any thoughts about this as well please.

Many thanks in advance.

It's not strange to pick names from mythology. NASA has used Apollo, Ares, Mercury, etc. and you don't see a lot of ancient Greek or Roman temples around here.

RonM makes a good point: it is often difficult to distinguish between myth and religion (and sometimes between myth and "science"). ;)

"Mars," for example. It's a term used in science. It is also used in mythology. And in discussion of some religious practices.

I am certainly not an Asian language scholar but it seems plausible the same could be true of the term "heavenly" in Chinese.

China is not an atheist country, the CP is at most nominally so. In reality China is home to hundreds of millions of Christians, Buddhists, and Muslims.

The use of "Heavenly" as part of the spacecraft name is totally fine. For Chinese, this word (Heavenly) doesn't imply any religious meaning. Chinese just like grand, beautiful, and natural names. The actual meaning of "天宮" is "Sky House", but if you translate it to "Heavenly Palace", Chinese are happy about that.

Looking at the illustrations of a docked Tianzhou (which must have a maximum diameter of 3.35 metres at the most), the diameter of the main Tianhe modules looks larger but not by a metre or more.

I should remark that Lyappa (Ляппа) is not a Russian word or name. Most probable this is the word lapa (лапа) erroneusly written. Yet lapa is also not an official name for this small manipulator -- its meaning is paw. It could be used metaphorically by somebody to explain the use of manipulator.

These solar panels will be in the same plane eventually, and on both sides of the station there will be larger solar panels(similar to ISS), so do not worry about this problem, the power generation from CSS will be three times the MIR.

I have just been nosing around on the Chinese site https://www.chinaspaceflight.com/China-Launch-Schedule.html and it has this list of launches in the Tiangong Complex programme:

2019     Tianhe 1, Tianzhou 2, Shenzhou 12

2020     Wentian, Tianzhou 3, Shenzhou 13

2021     Mengtian, Tianzhou 4, Shenzhou 14

2022     Tianzhou 5, Shenzhou 15, Xuntian (free-flying telescope)

Based upon this listing the Chinese are only planning one visit to the Tiangong Complex a year as it evolves, and I would guess that these visits might start with a 2-3 months residency and over 2-3 years build up to six months as the standard residency.   Clearly the Chinese are not planning to permanently occupy the station during the initial years - maybe that will come once all three modules are docked together around 2022?

In 2022 there is mention of a CZ-5B launch of "巡天号光学舱" which Google translates as "skylight optics cabin" - any ideas?   Maybe it's not connected with the Tiangong Complex, of course.

China to begin construction of manned space station in 2019

"This again announces the ambition and aspiration of the great rejuvenation of the Chinese people, and our resolute confidence in becoming a major space power," the space station project's supervisor Wang Zhaoyao told a news briefing in Beijing.

"After completing experimental stage spaceflight missions, we will enter the development and construction phase. According to our plans we will carry out the assembly and construction of China's manned space station between 2019 and 2022."

Re my earlier postings about the launch schedule for the Tiangong Complex and supporting spacecraft, I have now realised that the entry for "巡天号光学舱" is a hyperlink (I can't always tell which are hyperlinks because of my sight problems) and that takes you to a page dedicated to Xuntian.   So there are clearly two entries for this satellite.   The "空间站巡天光学舱(XT)" entry is not a hyperlink.

I am attaching a diagram of Xuntian - are there any Chinese speakers who would be kind enough to translate the captions, please?

Have there been any hints of other free-flying modules that will be associated with the Tiangong Complex and will occasionally dock for servicing operations?

As China has demonstrated automated docking without crew, this could be the plan for the Modular Space Station as well. This also avoids any risk to the crew in case anything goes wrong during docking.

CNSA is planning Shenzhou 12 manned flight shortly after the core module sent into orbit , the crew members will stay there for 3 months. In 2020-2022 ,there will be another LM5B launch (2 Lab modules) and Shenzhou 13 crew members will stay for 180 days until another crew relay , just like ISS

Thank you for those details.

We know that Shenzhou 12 and 13 are both due in 2020 so maybe that will see a crew handover?   Then again, most depictions of the side-mounted modules arriving seem to suggest that there won't be a crew on board at the time (no Shenzhou docked).   I thought that the permanent residencies would begin once the three main modules were docked in 2021 (or 2022).

It will be interesting to see whether the Chinese will try any really long duration visits to the Tiangong Complex.   By the mid-1990s the Russians had decided that their experience was that the optimum residencies for medical/psychological reasons would be around six months (at the time NASA was still extrapolating from Skylab data!).

https://gbtimes.com/launch-of-first-chinese-space-station-module-delayed-to-2020

This still gives the Chinese a good chance of having all three modules docked in orbit and the Tiangong Complex occupied in time for the 20th anniversary of Shenzhou 5 (which flew in October 2003): if that is a consideration for the Chinese, of course!

The article referenced immediately above suggests that Tianhe 1 will operate in a 393 km orbit.   At first i thought that this might mean a daily 15-circuits repeating pattern.

However, the Chinese orbital altitudes are about 5 km different from those obtained when a spherical Earth with a radius of 6,3678.145 km is used.   Whilst realising that such activity can be dangerous I have spent some time playing with the numbers and come up with a better-fitting repeating pattern: 107 circuits over 6.9 days, period 92.547 minutes, mean altitude over a spherical Earth 399 km.   This is a much longer repeating pattern than we have previously seen.

Time will tell ...........

I don not know.   I had assumed that they had their own model.
They use height above medium Earth radius of 6370.97 km.
Chinese heights when announced precisely are 7.1-7.2 km higher than Sven Grahn's RepeatPatternX program show for the same repeat pattern. I assume the model is the same but Sven's reference is 6378.14 km.
Medium orbital height from TLE related to the same 6378.14 km reference is usually 3.0-3.1 km higher than Sven's and 4.0 km less than the Chinese one.

Examples (Sven -- TLE -- Chinese):
HJ-1A/B: 641.9 -- 644.9 -- 649.1
GF-1: 637.4  -- 640.6 -- 644.5

"BEIJING, July 8 (Xinhua) -- China is accelerating its timetable for a space station, with the core capsule expected to be launched in 2020, says Yang Liwei, director of the China Manned Space Engineering Office and the country's first astronaut.

Yang told Chinese media recently that the two experiment modules of the space station will be sent into space in 2021 and 2022. Three or four manned missions and several cargo spacecraft are planned in 2021 and 2022.

After construction of the main parts of the space station, a capsule holding a large optical telescope will be sent into the same orbit to fly with the station, Yang said.

During construction of the station, the number of manned space missions will rise to about five a year, compared with once every two or three years when China began sending astronauts into space more than a decade ago. Astronaut recruitment will be expanded."

The test consisted of eight procedures that covered all working conditions of an in-orbit experiment module. It also simulated possible errors the module may encounter in space, according to a research institute affiliated with China Aerospace Science and Technology Corporation (CASC).
The test proved that the design of the propulsion system was scientific and its parameters setting was correct, according to the institute.
Two experiment modules of China's planned space station will be sent into space in 2021 and 2022, according to Yang Liwei, director of the China Manned Space Engineering Office and the country's first astronaut.
China is accelerating its timetable for a space station, with the core capsule expected to be launched in 2020, said Yang.

BEIJING, Aug. 18 (Xinhua) -- Engineers have successfully tested the propulsion system of China's planned space station lab capsules, a key step in its space station program.
Weighing 66 tonnes, the space station will comprise a core module and two lab capsules. The propulsion system will determine whether lab capsules can move in space.
Engineers designed 36 engines for the propulsion system with four to adjust the capsules' operation orbit and 32 to adjust flight attitude. Each engine is designed to work for at least 15 years, according to the China Aerospace Science and Technology Corporation (CASC), the main manufacturer of the space station.
The engines worked well and passed tests in Shanghai, said the CASC.

It might be interesting to try some comparison with Mir.

At 65 tons with three large modules in a T-shape, it will somewhat look like Mir as of 1990. That is - DOS-7 + Kvant-1 + Kvant-2 + Kristall. With Tianzhou playing the role of the FGB tug - and Progress altogether.

I'm not surprised either than the annual number of Shenzhou flights surges to 5 a year: that's pretty much Soyuz flight rate since Salyut 6 in 1978, up to the ISS days.

ISS has had a large number of useful experiments, also there has been experience gained around ECLSS as well as long duration effects of weightlessness.

It's kind of a canard that there is no real use for stations. It might be true that the knowledge might be gained at a cost that some might not consider a good value, but to say no knowledge, no use? Not a very useful post since the truth is different.

To add there was a short news piece in a recent issue of New Scientist talking about how there was concern at ISS ending in 2024 because a number of the longer term scientific experiments wouldn’t be finished by then, and how difficult and costly it would be to complete them in other ways.

ISS is in my view essential to a space future now.  There is nothing it does that "makes money" but since we are going to spend the money anyway.  It is the magnet that will, if the money is spent well, allow private enterprise to develop the keys (parts) to allow "someone" to put them together and make money with those parts.

The point I inelegantly made was that none of the claims for what it would do which were made in the 1980 period as the build was argued for...have occurred or are likely to.  And it seems the Chinese are building one, to build one.  They have the money.

China to conduct large-scale experiments in space station
BEIJING, Sept. 26 (Xinhua) -- China will carry out large-scale scientific experiments on space application projects after the completion of China's space station, according to a news briefing on China's space projects Wednesday.
China's manned space station is planned to be completed around 2022 and will be in orbit for more than 10 years.
"After the completion of the space station, space experiments and applications will become the main focus of the project," said Lin Xiqiang, deputy director of the China Manned Space Engineering Office, at the briefing.
Lyu Congmin, deputy chief designer of the space station's application system, said the space station will be a platform for more frontier space science experiments and applications.
"We have planned more than 13 laboratories and experimental platforms in the space station. A large optical telescope will be sent into the same orbit to fly with the station," Lyu said. "We will conduct more than 30 research projects in eight areas, including space astronomy, space life science and biotechnology, microgravity fundamental physics and space materials."
"The space station can support space applications in and out of the cabin, and the payload can be adjusted in orbit," said Lin. "I believe the large-scale experiments will bring more important achievements with international influence and application value."

In a May 2015 interview with the RIA Novosti news agency, the deputy general director of the Russian Nudelman Precision Engineering Design Bureau (KB Tochmash) Vladimir Slobodchikov disclosed that his company was planning to build a lidar to be used in a "spacecraft docking system" of an unidentified foreign partner. "Basically, it is an information exchange system for space vehicles. The instrument can be used both as a detector and as a rangefinder. Currently we are holding talks and the technical specifications have been agreed upon", he said. The interview (in Russian) is here:

https://ria.ru/interview/20150519/1065282573.html

KB Tochmash is a weapons manufacturer whose main role in the space program so far has been to build anti-satellite weapons and it is not impossible that the lidar has its roots in one of those programs.

The only foreign partner that builds spacecraft docking systems and is not involved in ISS is China, so is KB Tochmash building a laser rangefinder for Shenzhou and/or Tianzhou dockings with the Chinese modular space station? And why would China have to rely on Russia to deliver such a system?

KB Tochmash's annual report for 2013 (the only one available online) mentions a contract signed with China on a research project called "Counter-terrorism" ("Antiterror"). This is obviously not related to the lidar, but it does show that KB Tochmash has done business with China before. The annual report (a RAR file in Russian) is here:

Presentation of the Chinese modular space station "Tianhe"
October 23, 2018 at the 5th Scientific Conference on Astronautics, which takes place in the city of Xi'an (PRC), a presentation of the new Chinese modular space station Tianhe was held.
When assembled, it should become the third multi-module manned orbital station in the world (after the Mir and the ISS stations), much smaller, but generally similar in function to the Mir orbital station.
The first module of the station is planned to be placed into Earth orbit in 2020. Manned ships "Shenzhou", modules weighing 15-20 tons, and automatic cargo ships of supply "Tianzhou" with a payload of 6 tons should dock to this orbital station.
Completion of construction is scheduled for 2022 with a lifespan of 10-15 years. When fully assembled, without QC, it will weigh about 60-80 tons, about 2 times less in mass and size to the Soviet station complex "Mir" (124 tons) and 7 times less than ISS (417 tons).
In contrast to the one-module visited orbital spacecraft Tyangun-1 and Tyangun-2, the Chinese space station consists of several modules. The base module of the station has its name - "Tianhe". It is planned to connect two laboratory modules to it: "Wentian" and "Mentian" so that all three modules form the letter "T". The transport manned ship "Shenzhou" and the cargo ship "Tianzhou" will dock with this structure.
The basic Tianhe module has 5 docking stations, therefore, in the future, this configuration of the modular station can be expanded with additional modules.
It was decided to make the module with the Xuntian telescope autonomous, but it will have a common orbit with the station. And it will periodically moor to the axial docking station of the docking station for maintenance and replacement of scientific instruments.
A full-size mock-up of the Tianhe modular space station will be demonstrated at the aerospace show in Zhuhai in early November of this year.

That was pretty good. Core module is 4 m in diameter, 17 m long and more than 20 t in mass. The front module can accommodate from three to six taikonauts. The video showed the robotic arm assembling the station. The interior was off limits to the camera crew. That will be shown closer to launch.

What parts of the station would be assembled by the big arm?
I imagine a system similar to the soviet "Lyappa" would be used to move the autonomously docked modules from the front to the port and starboard docking ports. I see small grapple points on the node of the core module almost identical to Mir. But those would of course use their own little Lyappa-style arms, no need for a big ISS-style arm.

I would have expected that the Xuntian telescope would have been capable of docking automatically without using a remote manipulator arm.   From Chinese animations we know that it will use the front longitudinal port, with the visiting Shenzhou relocated to the lower berthing unit.

should have been more detailed. Think HST servicing missions with RVA and EVA servicing. That is one of the reasons why it can dock.

Physicist Wang Yifang, the mastermind behind the project, gives Nature an update on the ambitious project

Though extensively about Chinese plans for a future particle smasher this is also covered in it.

Quote
The institute is also pitching to fly an experiment—a detector measuring highly energetic particles known as cosmic rays—on China’s crewed space station, set to launch in 2020. What will it do and how will it improve on existing experiments?

Quote
We want to know where cosmic rays come from, and how they get such high energy. Answers to these questions will help us to understand the Universe. We would also like to use it to search for new particles, such as dark matter, which cannot yet be generated by accelerators on Earth. One of today’s best experiments for studying this is the Alpha Magnetic Spectrometer (AMS) on the International Space Station, which has not yet seen clear evidence of dark matter. That means we need experiments that can detect more particles, and at higher energies. The High Energy Cosmic Radiation Detection experiment will be able to study particles roughly ten times the energy of the AMS, and measure their energies with better resolution. We’ve almost finished our design and we’re now trying to get support from the Chinese government. We’re probably talking about US$200 million to $300 million for the detector. It’s on the list of candidates for possible projects for the future Chinese space station. We have to wait, but I am optimistic.

It is also rumored that LM-5 return to flight is postponed indefinitely. If the rumor turns out to be true, Change-5,6, Mars exploration mission, and the space station will also be delayed indefinitely.
Can anyone confirm the current status of LM-5 program and YF-77 engine problem? Thanks.

Surely, it would just be a case of redesigning the 'LOX Turbopump fault' and flying again when the problem is resolved - however long that takes? I doubt the Chinese space agency would just shelve something for good when a problem could be fixed.

The engines originate from Ukraine but are licensed built in China with China receiving the knowledge to build successor engines since they had no prior hydrolox booster engine experience so fixes are much more involved.
Or I may be thinking YF-100 but I think I recall that both are Ukrainian tech or YF-77 is Russian.

Just the YF-100 which is derived from the Soviet era RD-120.

As I understand it, the YF-100 is indeed an RD-120 derivative. But the YF-77 is an hydrolox gas generator, thus I assume an indigenous development. They have been using hydrolox for a long time and have seen some Chinese papers on the TP design.

China has not one but two Tianhe Space Stations. That two Mir-like Stations awaiting launch. Following Soviet protocol of always having a backup Station incase you lose one in launch.

Not really surprising since a few years ago the Chinese indicated that they have the option to add a second core module and two more "radial" modules to the basic three-module Tiangong Complex which they have announced.

China's space station core module, manned spacecraft arrive at launch site (http://www.xinhuanet.com/english/2020-01/20/c_138721451.htm)
Quote
A core module prototype of China's space station and a prototype of China's new-generation manned spacecraft arrived at the launch site in south China's Hainan Province after a week of ocean and rail transport, the China Manned Space Engineering Office (CMSEO) announced Monday.

The core module will take part in joint rehearsals with the Long March-5B carrier rocket at the Wenchang Space Launch Center while the new manned spacecraft will be launched by the rocket's maiden flight in the first half of this year.
This means the building of China's space station in space will begin soon, the CMSEO said.

The core module, named Tianhe (harmony of the heavens), will function as the command and control center of the space station. It is 16.6 meters long with a diameter of 4.2 meters and a takeoff weight of 22.5 tonnes.

As the largest spacecraft ever developed by China, Tianhe will accommodate three astronauts and serve as a space laboratory to carry out scientific research and technological verifications, the CMSEO said...

Quote
In order to conduct the microgravity combustion experiments in China Manned Space Station, it is necessary to establish an onboard combustion science experiment system. With the experimental study of microgravity combustion, it is beneficial to expand the depth and breadth of combustion research and promote the development of combustion science. According to the functions to be realized and the requirements of combustion experiments, the design and analysis of the experimental system for combustion science rack are carried out. The combustion experiment system consists of eight subsystems, which is a comprehensive experiment system that is suitable for combustion experiments with gas, liquid and solid fuels, respectively. In consideration of the strength design requirements, after the completion of the scheme design, the finite element analysis of the system is carried out, and the mechanical environment experiment is completed with the developed structural setup. The experimental and analytical results show that the design can meet the requirements of the environment simulation experimental outline, and is reasonable and feasible for space experiments.

The Long March-5B rocket will carry into space the core module and lab capsules, as well as a capsule holding a 2-meter-caliber optical telescope, which will fly in the same orbit as the space station.

The telescope capsule, named Xuntian, is expected to provide observation data for astronomical and physical studies to help scientists better understand the universe. During its expected 10-year operation, it will be able to observe over 40 percent of the sky, said Zhou.

The capsule can dock with the space station for maintenance and refueling. 

This is nice!
The station could also perform as a sort of a space garage.
But is it really helpfull to have a telescope in an easily accessible orbit?

China to launch core module of space station in first half of 2021
2020-12-25 20:41:57

CHANGSHA, Dec. 25 (Xinhua) -- China plans to launch the core module of its manned space station in the first half of 2021, a senior official said Friday.

The core module will be sent by a Long March-5B Y2 rocket from the Wenchang Spacecraft Launch Site in Hainan Province, said Zhou Jianping, chief designer of China's manned space program, at a handover ceremony for the return capsule of the Shenzhou-10 manned spacecraft in Shaoshan, central China's Hunan Province.

"Subsequent space missions include the launches of Tianzhou-2 cargo craft and Shenzhou-12 manned craft after the core module is sent into orbit," Zhou said.

Tests on the core module have been completed, and astronaut training is underway. The astronauts will carry out a number of extravehicular activities.

China is scheduled to complete the construction of the space station around 2022. The construction project will be implemented in two phases. Six flight missions, including the launch of the core module, have been scheduled in the phase of key technology validation.

Some good shots of the station's docking ports here. Can anyone tell whether they look like APAS or IDS standard? (I'm not visually familiar enough with the differences to distinguish them...)

In the past China has used a derivative of APAS on their stations, but there have been reports/statements that they intend to make Tiangong (and visiting vehicles going forward) compatible with the newer IDS standard. I'm curious whether they are actually going through with that or if that was just an unfounded/misinterpreted rumor.

At the moment the idea of transnational space station visits with China (Dragon/Starliner/DC to Tiangong or Shenzhou to ISS) would seem like a pipe dream on legal grounds, but it would make a lot of sense to at least try to make them as compatible as possible, so as to keep options open. (IDS is supposed to be structurally superior to boot - less impact on the station's structure from repeated dockings, which also makes it easier to abort a docking since approach velocity is reduced.)

APAS is the version of IDSS offered by RSC Energia. A newer version of APAS is in development for proposed projects (i.e. Gateway et al) that is fully IDSS compliant with built in redundancy features. The Chinese licenced version of APAS is known in English as CDS or China Docking System.
 
China required it to be built to ISS MCB docking system requirements so that each station can serve the other as well as commercial stations in emergency situations.

Thanks - that clears things up quite a bit!

I keep forgetting that the IDSS standard, like APAS before it, allows for substantial independence in how it's implemented mechanically by different nations and companies, even as the interface itself is mutually compatible. The last time the U.S. built a docking system indigenously prior to NDS was for Apollo-Soyuz, and apparently their implementation of that original version of APAS was quite different mechanically than the Soviet one. So I can see how NASA/U.S.-focused sources would draw a sharper terminological line between "APAS" (referring to the legacy high-impact system as implemented by the PMAs and Shuttle's docking adapter) versus "IDS/NDS" (the modern low-impact system as implemented by the IDAs and Commercial crew vehicles), compared to Russian/Chinese-focused sources. NDS, NASA's reference implementation of IDSS developed by Boeing out of the LIDS project and used by the IDAs, seems to be a clean-sheet design deriving from neither the historical American Apollo-Soyuz APAS implementation, nor from the Russian-proprietary implementation used on Shuttle-ISS/Mir, hence NASA doesn't refer to their new ports as "APAS". Likewise SpaceX, which opted to do their own clean-sheet implementation of IDSS instead of buying Boeing's, wouldn't be able to claim APAS heritage per se. But since Russia has been continuously producing and evolving docking hardware from the 60's to the present day, it stands to reason their implementation of IDSS would have more substantial mechanical heritage in APAS, hence why they continue to use that term to describe it. (Did I get all that right? :) )

I do find it interesting that China is choosing to put its new space station in a ~42° orbit instead of a ~51.6° orbit matching the ISS's. Having compatible docking ports is nice but not especially useful when the two stations are separated by so much delta-v; it limits the utility in "emergency situations" to ones where one nation's vehicle is launching fresh from the ground to visit the other's station, as opposed to traveling from one station to the other. Just as Mir and the ISS were supposed to overlap and allow for cross-visits (as was done between Mir and Salyut 7), it seems most if not all near-term commercial stations will be joining the 51.6° inclination for that reason. (Axiom Station in particular, being the most credible plan for a commercial station right now, will have to be at 51.6° because it will start out as an extension to the ISS.)

It also freezes out Russia from sending Soyuz/Progress/Oryol vehicles to the Chinese station since none of their launch sites can reach 42°, which strikes me as strange considering how closely involved Russia and China have been on this project (and Russia's recently stated intent to double down on that partnership in the future instead of getting more involved with the U.S.). Even if they launched straight east from Baikonur (which I suppose they could do in partnership with China, since Baikonur's azimuth restrictions are driven by the need to avoid overflying Mongolia), they still wouldn't be able to get any lower than ~45° without a substantial dogleg. Are China's launches for station modules and visiting vehicles so mass-constrained that they can't spend the small extra delta-v to go to 51.6°? It just seems like the smarter play considering that's where all the action is.

Or am I overestimating the difficulty of the dogleg necessary to get to 42° from Baikonur or Vostochny? I can't imagine Soyuz-2.1a being able to pull it off given it's tightly mass-constrained on Soyuz and Progress launches, but maybe if they bumped it up to a Soyuz-2.1b they could do it?

The IDA's development, design and manufacture involved Boeing, RSC Energia et al. The IDSS calls for an impact range supporting legacy APAS impact velocities to LIDS ultra low impact velocities. This may change in a future revision years to decades in the future.

Chinese launches can reach 51.6. They have been back and forth on the planned inclination. Also Russia has been given frozen water over the past few years in Chinese discussions because China's Central Committee et al have declined to give authorization and the Chinese side has to have approvals for anything beyond pondering discussion. If you have a subscription Russian Space Web this is greatly detailed and goes in to the repeated deal breakers including topics outside of space. It heavily relies on Russia increasingly not having much to offer major technologies wise with China having lapped Russia in many fields. It also comes down to that if it is not approved in China's 5 year plans and not proposed first by them then approvals are hard to come by.

In the past China has used a derivative of APAS on their stations, but there have been reports/statements that they intend to make Tiangong (and visiting vehicles going forward) compatible with the newer IDS standard. I'm curious whether they are actually going through with that or if that was just an unfounded/misinterpreted rumor.

At the moment the idea of transnational space station visits with China (Dragon/Starliner/DC to Tiangong or Shenzhou to ISS) would seem like a pipe dream on legal grounds, but it would make a lot of sense to at least try to make them as compatible as possible, so as to keep options open. (IDS is supposed to be structurally superior to boot - less impact on the station's structure from repeated dockings, which also makes it easier to abort a docking since approach velocity is reduced.)
APAS is the version of IDSS offered by RSC Energia. A newer version of APAS is in development for proposed projects (i.e. Gateway et al) that is fully IDSS compliant with built in redundancy features. The Chinese licenced version of APAS is known in English as CDS or China Docking System.
 
China required it to be built to ISS MCB docking system requirements so that each station can serve the other as well as commercial stations in emergency situations.
Thanks - that clears things up quite a bit!

I keep forgetting that the IDSS standard, like APAS before it, allows for substantial independence in how it's implemented mechanically by different nations and companies, even as the interface itself is mutually compatible. The last time the U.S. built a docking system indigenously prior to NDS was for Apollo-Soyuz, and apparently their implementation of that original version of APAS was quite different mechanically than the Soviet one. So I can see how NASA/U.S.-focused sources would draw a sharper terminological line between "APAS" (referring to the legacy high-impact system as implemented by the PMAs and Shuttle's docking adapter) versus "IDS/NDS" (the modern low-impact system as implemented by the IDAs and Commercial crew vehicles), compared to Russian/Chinese-focused sources. NDS, NASA's reference implementation of IDSS developed by Boeing out of the LIDS project and used by the IDAs, seems to be a clean-sheet design deriving from neither the historical American Apollo-Soyuz APAS implementation, nor from the Russian-proprietary implementation used on Shuttle-ISS/Mir, hence NASA doesn't refer to their new ports as "APAS". Likewise SpaceX, which opted to do their own clean-sheet implementation of IDSS instead of buying Boeing's, wouldn't be able to claim APAS heritage per se. But since Russia has been continuously producing and evolving docking hardware from the 60's to the present day, it stands to reason their implementation of IDSS would have more substantial mechanical heritage in APAS, hence why they continue to use that term to describe it. (Did I get all that right? :) )

I do find it interesting that China is choosing to put its new space station in a ~42° orbit instead of a ~51.6° orbit matching the ISS's. Having compatible docking ports is nice but not especially useful when the two stations are separated by so much delta-v; it limits the utility in "emergency situations" to ones where one nation's vehicle is launching fresh from the ground to visit the other's station, as opposed to traveling from one station to the other. Just as Mir and the ISS were supposed to overlap and allow for cross-visits (as was done between Mir and Salyut 7), it seems most if not all near-term commercial stations will be joining the 51.6° inclination for that reason. (Axiom Station in particular, being the most credible plan for a commercial station right now, will have to be at 51.6° because it will start out as an extension to the ISS.)

It also freezes out Russia from sending Soyuz/Progress/Oryol vehicles to the Chinese station since none of their launch sites can reach 42°, which strikes me as strange considering how closely involved Russia and China have been on this project (and Russia's recently stated intent to double down on that partnership in the future instead of getting more involved with the U.S.). Even if they launched straight east from Baikonur (which I suppose they could do in partnership with China, since Baikonur's azimuth restrictions are driven by the need to avoid overflying Mongolia), they still wouldn't be able to get any lower than ~45° without a substantial dogleg. Are China's launches for station modules and visiting vehicles so mass-constrained that they can't spend the small extra delta-v to go to 51.6°? It just seems like the smarter play considering that's where all the action is.

Or am I overestimating the difficulty of the dogleg necessary to get to 42° from Baikonur or Vostochny? I can't imagine Soyuz-2.1a being able to pull it off given it's tightly mass-constrained on Soyuz and Progress launches, but maybe if they bumped it up to a Soyuz-2.1b they could do it?
The IDA's development, design and manufacture involved Boeing, RSC Energia et al. The IDSS calls for an impact range supporting legacy APAS impact velocities to LIDS ultra low impact velocities. This may change in a future revision years to decades in the future.

Chinese launches can reach 51.6. They have been back and forth on the planned inclination. Also Russia has been given frozen water over the past few years in Chinese discussions because China's Central Committee et al have declined to give authorization and the Chinese side has to have approvals for anything beyond pondering discussion. If you have a subscription Russian Space Web this is greatly detailed and goes in to the repeated deal breakers including topics outside of space. It heavily relies on Russia increasingly not having much to offer major technologies wise with China having lapped Russia in many fields. It also comes down to that if it is not approved in China's 5 year plans and not proposed first by them then approvals are hard to come by.
Link to subscription article that details why Russia and China won't be doing anything jointly anytime soon. Yes it is not about space stations but the same applies: http://russianspaceweb.com/protected/spacecraft-manned-lunar-china.html

The Jiuquan launch center is at 41°N so if the station were orbiting in that inclination, Shenzhou 12 (and presumably subsequent Shenzhou) would have regular opportunities to launch due east into the orbital plane of the station.

Great thread about Xuntian (free-flying, Tiangong-tended space telescope):
https://twitter.com/dr_guangtou/status/1384547272264925188
Transcript below, but do check the Twitter thread for images:
Quote
Here is a thread about CSST (Chinese Space Station Telescope): A low-orbit, 2-m NUV-optical space telescope focusing on large sky surveys. It is a separate module of the new space station and planned to launch around 2025.
The telescope has an off-axis TMA design using SiC mirrors with some "active" capability for in-orbit adjustment. It has ~1.1 deg^2 FoV for the main sky survey while having four separate small instruments. The designed resolution is around 0.12-0.15 arcsec.
The main goal of CSST is a multi-band (NUV, u, g, r, i, z), large area (17500 deg^2) sky survey to r>25 mag that also has grism spectra coverage (r~22). There is also a 400 deg^2 deep field and 1 or 2 much smaller UD fields.
The main instrument is a very complicated camera for the main survey. Instead of a sophisticated filter change mechanism, the focal plane may remind you of the original SDSS survey: each detector has a fixed filter on it.
Another important component is a multi-channel imager (MCI) that can observe in three-band simultaneously. It has a 7.7x7.7 arcmin FoV with 0.05 arcsec/pixel resolution. It will bring ~30 broad+medium+narrow band filters. I call it "poor man's WFC3".
CSST will also carry a small optical IFU instrument using an image slicer, mainly for scientific demonstration. It has a 6x6 arcsec FoV, 0.2 arcsec spatial resolution, and covers 0.4-0.9 micron in wavelength with R>1000.
Another interesting aspect of CSST is: it can dock to the space station for maintenance and upgrade in the future! In the current design, >20 modules of the telescope can be replaced or have the potential for upgrade.
[...]
Some personal notes: I have been involved in CSST science preparation for a little bit, and it will be an important part of my plan for the next five years. While being super excited about it, I also feel very nervous... Chinese astronomy community is still pretty new and relatively small. Compared to the American and European communities, we still lack the experience to handle such a complex space telescope project. So there will a lot of trial and error... Luckily, we do have a group of brilliant young scientists working on it, and that gives me all the hope I need. Hopefully, I can put this ambitious project on your radar. And hopefully, we can develop many international collaborations using CSST data.

So is SZ14 to be in independent flight during the docking of Wentian and Mengtian? And would they leave Wentian at the forward docking port until Mengtian arrive so to keep things mostly symmetrical?

I think that the crew of SZ-14 will assist the docking of the two modules within the station.

I suppose we will see an 'L-shaped' station for some time. Wentian will dock on the axial port and then be moved to a lateral port shortly before Mengtian launch. Then Mengtian docks also on the axial port and will be moved to the lateral port opposite do Wentian. Just like has been done on Mir.

With SZ-15 docked at the same time as SZ-14, this looks to be the first Tiangong crew station rotation.

From the video Tian He (pronounced tian hur) mass is 22.5 t. Altitude 400 km. Tian He has 50 m³ internal volume. Minimum crew is three, but can sustain 6-7 crew. Uses UDMH/N2O4 propellant to maintain orbit. The silver domes are covers for viewing ports (css-02). Exercise bike (css-03). Main lab (css-04). Can hold 8 t of propellant. Total mass is 62 t with Wentian, Mengtian and Shenzhou. Working with UN and 80 other countries for microgravity experiments. Has robotic arm. Space toilet (css-08). Looks a lot like the Shuttle toilet. Food pack (css-09,10). CSS could carry a robot in the future. Astronaut tilt table (css-11). EVA suit (css-12).

Yes, you are right. These are one of the six gyroscopes. There are two small round windows (portholes) on port and starboard. And maybe in some doors of the docking ports.

That seems a little on the small size for a module of this size and configuration, and the interior shots that we have seen.  the roughly similar Mir  base block was ~100 m3, Salyut 6 and 7 ~80, I think.

I wonder then if this refers to habitable rather than pressurised volume?

50m3 is the habitable volume which refers to the narrow part of the module, the wider part got 90-100m3, makes it a combination of 150m3 pressurized volume.

I'm curious to see if that is what they actually do. If you think about it, that could create some major design headaches, because if the instruments are contained in a pressurizable compartment, then they have to be isolated from the vacuum. If an astronaut pulls out an instrument, it cannot open up a hole that allows the air to escape. It might make more sense to do all of that servicing unpressurized.

Pressurized servicing was considered in some NASA telescope designs in the late 1960s, but that was abandoned.

Great resource! I wonder though if Tianzhou 2 and 3 docked operations overlap how Shenzhou 13 can dock to an axial port, since both are occupied. Does it mean nadir port maybe instead (as this is the other one for Shenzhou docking operations)? Edit: nadir port confirmed by graphics and videos

Based on this infographic and NET dates published on Twitter I constructed this guesstimated current timeline of upcoming CSS operations:

May 29 at ~12:55 UTC - launch of Tianzhou 2 on CZ-7

Confused about the arm being used to install the two science modules: don't they carry their own smaller manipulator systems? Also: the video shows the Tianhe solar panels being dismounted: is that really planned?

Video also shows a future extension of the arm almost doubling its length.

It was mentioned that  the solar panels in core module were designed that way. In the feature (with budget allowed) they have 2nd stage plan to extend CSS which will launch another tianhe core module attached to current forward dock with two EU made modules. Anticipating the new core module will likely have solar panels with higher efficiency and obstruct current tianhe panels, the old ones will be moved to end of experimental modules.

CASC’s mission booklet (https://forum.nasaspaceflight.com/index.php?topic=26876.msg2230607#msg2230607) and most Chinese sources I have seen is disagreeing with that on the Experiment Modules numbering - all of them has Wentian as EM I and Mengtian as EM II.

Indeed. Now that you mention it, can anyone provide a sense of how they compare to Mir's Spektr/Kristall/Priroda TKS-derived modules, to which Mengtian and Wengtian share a visual resemblance (at least size-wise, I assume internally and capability-wise they'll be quite different, as Tianhe is from DOS-like modules)?
Title: Re: Chinese Space Station
Post by: lucspace on 06/17/2021 02:52 pm
The bulk of Mengtian and Wentian seem to be of a diameter corresponding to the maximum diameter of Tianhe. In Mir, the bulk of the modules used the diameter of the middle section of its core module. So I would guess Tiangong's module volume to be significantly larger.
Title: Re: Chinese Space Station
Post by: Lars-J on 06/17/2021 03:39 pm
The modules max diameter is the same as the DOS / TKS series - 4.2m. But they seem to make better use of the volume, and the greater capacity of their launch vehicles to have slightly larger modules with significantly more usable volume.

1986 - 2021
Thanks for posting this - it's a very helpful illustration! :) It makes much more clear the ways in which Tianhe advances and improves up on the classic DOS design. Not as much of a straight knockoff as I had initially assumed from the renderings.

It clearly shows how much bigger Tianhe is compared to the Mir core. Both the "thick" and "thin" sections are longer, and the docking node at the front is a lot bigger (especially when you consider that Shenzhou, despite sharing Soyuz's outer mold line for the descent module, is actually scaled up somewhat).

This lines up with how in yesterday's videos, both Tianhe and Shenzhou appeared a lot roomier inside than Zvezda and Soyuz respectively. Shenzhou didn't look nearly as claustrophobic when the taikonauts were climbing into it. Not Dragon size of course (that's in a league of its own for now), but nothing like the pictures of crew crammed into Soyuz.

What's most striking about this is the picture it paints of what the Russian space program could have been if it had continued building on its rich portfolio of legacy designs in the post-Soviet era. Imagine if something the size of Shenzhou had been rolled out as a "Soyuz XL" in conjunction with the Soyuz-2.1b rocket when Soyuz-FG was retired. Or if a "new and improved DOS/FGB" had been the basis for Nauka instead of the mothballed Zarya spare. (I get the impression that the NEM modules, now intended for ROSS instead of ISS, will be more along those lines, if they ever come to fruition.)

In many respects, the Chinese space program has picked up the torch dropped by the Soviet Union and become the spiritual successor to its space program. It's like witnessing an alternate history of what a "Mir-3" might have looked like...

September (NET) - docking of Tianzhou 2 with forward port of Tianhe for propellant transfer testing
Some propellant transfer occurred before the launch of Shenzhou-12.
"Combined with Tianhe, Tianzhou-2 will replenish Tianhe's propellant and help test equipment for space application projects."

Previously: "The in-orbit refueling, under control of technicians on Earth, takes about five days, as the propellant is transmitted from the cargo spacecraft to the space lab."

Do we know why China is not aiming for continuous habitation? Could they switch to continuous habitation later?

One possibility is that they are constrained by docking ports.

My understanding is that they plan to move to continuous habitation in late 2022 with a direct handover from Shenzhou 14 to Shenzhou 15.

China Space Crew: One Month on Orbit


By Leonard David
July 18th, 2021

Three Chinese astronauts, Nie Haisheng, Liu Boming and Tang Hongbo, have worked and lived in the space station core module for a month since the Shenzhou-12 piloted spacecraft was launched into space.

The astronauts have been in good condition after completing their first extravehicular operations, according to the China Manned Space Agency (CMSA). A second spacewalk is scheduled to take place.

China’s space station is operating smoothly, with the trio of Taikonauts busily carrying out various duties, such as collection of trace elements in the air and performing routine medical examinations.

Exercise regime

According to China Central Television (CCTV), telecommunication facilities on board the core module enable the crew to watch the Xinwen Lianbo (News Simulcast), a domestic news program. Since they are stationed in the core module, the ground support team has been regularly sending them news programs, to keep them up to date on what is occurring on Earth.

They exercise for about an hour after watching the news, using sports facilities in the core module, such as an exercise bike and a treadmill.

“Their physical fatigue, sleep, eating and drinking water, the whole body metabolism, nutrition, health status, through our comprehensive evaluation, are very good,” Xu Chong, director of the medical supervision and insurance department of China Astronaut Research and Training Center told CCTV.

According to the ground supporting team, the astronauts’ exercise amount and intensity were decided in terms of their own physical conditions. Each of them has their own exercise plan.

“It’s a daily routine for the astronauts to do exercise. We have formulated different exercise plans for each of the three astronauts, with a training intensity reaching 60 to 80 percent of their maximum capacity. That’s a medium to high intensity for them. As they stay longer in space, we have to increase the intensity of their exercise plans, so that they are able to maintain the physiological effects against weightlessness,” said Li Yinghui, the deputy chief designer of the astronaut system with China Astronaut Research and Training Center.

Space experiments

Starting Saturday, the space travelers put on heart rate and rhythm recording devices as part of experiments in space medicine. For the first time ever, China’s space station used a scientific research cabinet that is capable of conducting space medicine and space life science experiments, setting a total of 49 space experiment projects.

During the Shenzhou 12 mission in space, the astronauts will complete 14 of them.

“We set three aims for these 14 experimental projects. The first one is that the mission needs the technologies that are able to support advanced development, so the projects were set for making technical reserves to support the mission,” said Li.

“The second one is to set sights on the leading edge, so as to obtain new discoveries and new explorations. The third one is to continuously accumulate long-term flight data,” Li told CCTV.

I don’t recall this being talked before, but some people are speculating from EVA training photos that the 2 solar panels of the CSS Tianhe Core Module will be moved to the ends of the 2 experimental modules some time in the future, perpendicular to the existing panels of these 2 modules.

I’m not sure if this is true…

Completed CSS operation milestones:

Apr. 29 at 3:23 UTC - launch of Tianhe on CZ-5B
May 29 at 12:55 UTC - launch of Tianzhou 2 on CZ-7
May 29 at 21:01 UTC - docking of Tianzhou 2 with aft port of Tianhe (+propellant transfer)
June 17 at 1:22 UTC - launch of Shenzhou 12 [Nie Haisheng, Liu Boming and Tang Hongbo] on CZ-2F/G
June 17 at 7:54 UTC - docking of Shenzhou 12 [Nie, Liu, Tang] with forward port of Tianhe
July 4 at 0:11–6:57 UTC - spacewalk (EVA-1) from Tianhe airlock (test of new space suits, installation of foot restraints, work platform and exterior panoramic camera, emergency return to airlock training) [Liu, Tang]
Aug. 20 at 0:38–6:33 UTC spacewalk (EVA-2) from Tianhe airlock (installation of external pump assembly, panoramic camera activation, foot restraints & extravehicular working platform installation on the robotic arm) [Nie, Liu]

Guesstimated current timeline of upcoming CSS operations:

Early September (NET) - undocking of Tianzhou 2 from aft port of Tianhe for rendezvous testing
mid-September (NET) - undocking from forward port & landing of Shenzhou 12 [Nie, Liu, Tang]
mid-September (NET) - docking of Tianzhou 2 with forward port of Tianhe (+propellant transfer testing)
Sep. 20 - launch of Tianzhou 3 on CZ-7
Sep. 20/21 - docking of Tianzhou 3 with aft port of Tianhe
Oct. 3 - launch of Shenzhou 13 on CZ-2F/G [Zhai Zhigang, Wang Yaping, Ye Guangfu (TBC)]
Oct. 3/4 - docking of Shenzhou 13 with nadir port of Tianhe [Zhai, Wang, Ye (TBC)]
October (NET) - robotic arm relocation testing of Tianzhou 2 (to side port)
October (NET) - undocking of Tianzhou 2 from forward (side?) port of Tianhe for EOM & reentry
March (NET) - undocking from nadir port & landing of Shenzhou 13 [Zhai, Wang, Ye (TBC)]
March (NET) - undocking of Tianzhou 3 from aft port & docking at forward port of Tianhe
March/April (NET) - launch of Tianzhou 4 on CZ-7
March/April (NET) - docking of Tianzhou 4 with aft port of Tianhe
May (NET) - launch of Shenzhou 14 on CZ-2F/G
May (NET) - docking of Shenzhou 14 with nadir port of Tianhe
May (NET) - undocking of Tianzhou 3 from forward port of Tianhe for EOM & reentry
May/June (NET) - launch of Wentian on CZ-5B
May/June (NET) - docking of Wentian at forward port of Tianhe

After this it gets a bit murky as Tianzhou 5 operations appear to overlap with Tianzhou 4 but there seems to be no free docking port. Maybe TZ-4 will undock before TZ-5 arrives as it was scheduled (according to Twitter) to fly later, in Oct. 2022.

July? (NET) - undocking of Tianzhou 4 from aft port of Tianhe for EOM & reentry
July? (NET) or October - launch of Tianzhou 5 on CZ-7
July? (NET) or October - docking of Tianzhou 5 with aft port of Tianhe

August/September (NET) - Mengtian launch on CZ-5B
August/September (NET) - docking of Mengtian at forward port of Tianhe
September? (NET) - robotic relocation of Mengtian from forward to port on Tianhe
November (NET) - launch of Shenzhou 15 on CZ-2F/G

Haisheng and Boming are the first names. The family names are Nie and Liu.

"Modern Chinese names consist of a family name (xìngshì; 姓氏), which comes first and is usually but not always monosyllabic, followed by a given name (míng; 名), which is almost always disyllabic, consisting of two characters. Prior to the 21st century, most educated Chinese men also utilized a "courtesy name" or "style name" (zì; 字) by which they were known among those outside their family and closest friends. Respected artists or poets will sometimes also use a professional "art name" (hào; 号) among their social peers."

Anyone interested in a CSS/Tianjin station topology. I've made a start, but require some help with determining what systems are located where inside the module. (I decided to now use the top as flight direction, so now Port (II) is left and Starboard (IV) Right.)
I think China really made a nice station with inspiration from Russian and 'western' ISS modules.
If I'm not mistaken, Tianhe has four experiment racks, all at the Aft.
IV(Starboard) looks like two HRF (Human Research Facility) beside each other. The most AFT one has drawers. The second rack looks to support the bicycle. And I think I can recognize a mass measurement device.
II (Port) and III (Overhead) are like EXPRESS racks, with 8x like lockers and two drawers.
The II (Port) rack, contains what looks like a two locker Incubator (? Glacier), a single locker centrifuge. And at the bottom a four unit vibration insulator (ultra weak gravity). One locker is stowage.
In the second Port row I think the Robotarm station is located.
I've not seen the content of the Zenith/overhead Express rack.
I'll end here, because one image can tell more than a thousand words. (I can visually match the racks with the CSS Handbook)

Image from CCTV shows neutral buoyancy training and impressive size of the modules to be added later.
EM-II, Mentian with experiment airlock? (and 4 ISPR rows); The diameter of the experiment airlock is equal to the pressurized section.
EM-I, Wentian has 6 ISPR rows; and an EVA airlock. That airlock has a smaller diameter. If I'm not mistaken.

@Galactic Penguin SST; this was handled earlier; page 10. and Reply #51 page 3
If I'm not mistaken this is part of the second phase of the CSS.
If China does this, they'll add another Tianhe to the forward port of CM: Tianhe. To this module they can add two experiment modules. The CM: Tianhe solar arrays will be shaded by those module, so they move them to the arrays of EM1 & EM2.

I've been following a very interesting conversation by Twitter users @RaffaeleDiPalma (posts here some wonderful EVA DOUG visualizations and timelines) and @SegerYu (a Chinese spaceflight expert) regarding a cool capability they have on CSS: apparently their crew's spacesuits are configured in such a way as to allow near-real-time representative 3D modeling on the ground of how exactly the crew is moving and what their actions are like on CSS. This is a remarkable capability IMO and one can see how it can help visualize what's going on when onboard or helmet cameras are not conductive to direct visual interpretation.

The conversation is distributed along different messages and subthreads, but a representative one can be found here:

Nice thread regarding the long arm ("ChinArm") currently on CSS and the shorter one to be launched with Wengtian (and Mengtian?), including very illustrative pictures:

https://twitter.com/SegerYu/status/1457966277167763457

Quote
Main tasks for SZ-13's first EVA:
1- Install the 'suspension device' (XGZZ hereinafter) of the 'combined series connector for double robotic arm' (aka adapter, ZJJ hereinafter).
2- Use the XGZZ, installed in the previous step, to capture and lock the ZJJ.
3- Try out typical astronaut movements when using the new Fentian spacesuit.
4- Try out the functionality of the EVA suit (golden stripes) carried on TZ-3 and check its compatibility with station equipment. Use the EVA suit's cameras to take pictures of the 3rd quadrant's robotic arm grapple fixture.

The first two tasks are related to the RMS, consisting of two arms: the Tianhe robotic arm (long arm) and the Wentian robotic arm (short arm) that will be launched with Wentian next year. The two arms are independent and can be used separately, or they can be linked to form a longer arm.

The outstretched length of the long arm is 10.2 m with 7 degrees of freedom and can transfer large loads (<25 tonnes), but is only capable of low accuracy due to its dynamic characteristics. The capture and latching mechanism adapts those from Canadarm2. The end effector allows to grapple the target fixture even with large attitude deviations. Three cables rigidize on the adapter's lever, with the latches reducing the attitude and position deviations in order to achieve a soft capture, to then rigidly lock the connection.

The small arm has an outstretched length of about 5 m with also 7 dof. It doesn't allow for the transfer of large loads, but has high control accuracy. Therefore, a tolerance-type capture mechanism is adopted. Upon capture, three fingers are firmly locked, the guiderails reduce positioning deviations, and the target adapter begins to retreat allowing for the three mechanical limit latches to insert themselves into the receiving orifices in the adapter to tighten the connection. There is no soft capture process.

The two arms have different performances and, in the majority of cases, work independently. However, in some situations such as helping astronauts large-scale load transfers, site inspections or solar wing movement, it will be necessary to combine both arms to create a longer one. In this case, an adapter between the two arms is needed, the aforementioned ZJJ, which can also transfer data and electricity between both arms. The XGZZ suspension device is needed for ZJJ maintenance.

The installation position for the XGZZ is in the narrow section of the core module, where the 1st quadrant line intersects the 4th quadrant one. The main mechanism in the XGZZ can be undestood as an end effector for the small arm. The XGZZ's base is fixed with six bolts and 3 rectangular data cable connectors to establish a data path with the control system.

During the EVA, after installing the XGZZ and checking it energizes correctly, load the command to remotely control the XGZZ and have it open the three fingers, at medium speed. Align the end of the small arm adapter ZJJ with the XGZZ to complete capture, then instruct the three fingers in the XGZZ to close in order to achieve a firm capture, then pull it back to achieve a rigid connection (with the retraction into the orifices). These tasks were completed.

There was also an unplanned task, since it was suspected the crew might have "stepped on" a cable connector for the long arm's target adapter in the 3rd quadrant. Ground wasn't sure if the connector was loose or not, and the panoramic camera couldn't get a clear view. So the crew was asked to take pictures with an exterior camera to analyze the situation on the ground.

Seems they're also using/developing a SAFER-like rescue jetpack reportedly named "SAFEST".

Completed CSS operation milestones:

Apr. 29 at 3:23 UTC - launch of Tianhe on CZ-5B
May 29 at 12:55 UTC - launch of Tianzhou 2 on CZ-7
May 29 at 21:01 UTC - docking of Tianzhou 2 with aft port of Tianhe (+propellant transfer)
June 17 at 1:22 UTC - launch of Shenzhou 12 [Nie Haisheng, Liu Boming and Tang Hongbo] on CZ-2F/G

Aug. 20 at 0:38–6:33 UTC spacewalk (EVA-2) from Tianhe airlock (installation of external pump assembly, panoramic camera activation, foot restraints & extravehicular working platform installation on the robotic arm) [Nie, Liu]
Sep. 16 at 0:56 UTC - undocking of Shenzhou 12 from forward port of Tianhe (+rendezvous test at nadir port) [Nie, Liu, Tang]
Sep. 17 at 4:45–4:48–5:34 UTC - jettison of OM & deorbit burn & landing of Shenzhou 12 [Nie, Liu, Tang]
Sep. 18 at 2:25~6:25 UTC - undocking of Tianzhou 2 from aft port of Tianhe and docking with forward port of Tianhe (+propellant transfer testing)
Sep. 20 at 7:10 UTC - launch of Tianzhou 3 on CZ-7
Sep. 20 at 14:08 UTC - docking of Tianzhou 3 with aft port of Tianhe
Oct. 15 at 16:23 UTC - launch of Shenzhou 13 on CZ-2F/G [Zhai Zhigang, Wang Yaping, Ye Guangfu]
Oct. 15 at 23:48 UTC - docking of Shenzhou 13 with nadir port of Tianhe [Zhai, Wang, Ye]
Nov. 7 at 10:51–17:16 UTC spacewalk (EVA-3) from Tianhe airlock (testing of new spacesuit, installation of robotic arm adapter/end effector) [Zhai, Wang]
Dec. 26  at 10:44–16:55 UTC spacewalk (EVA-4) from Tianhe airlock (deployment of external camera platform C, object translation movement testing) [Zhai, Ye]

Guesstimated current timeline of upcoming CSS operations:

January (NET) - robotic arm relocation testing of Tianzhou 2 (to side port)
January (NET) - undocking of Tianzhou 2 from forward (side?) port of Tianhe for EOM & reentry
March (NET) - undocking from nadir port of Tianhe & landing of Shenzhou 13 [Zhai, Wang, Ye]
March (NET) - undocking of Tianzhou 3 from aft port & docking at forward port of Tianhe
March/April (NET) - launch of Tianzhou 4 on CZ-7
March/April (NET) - docking of Tianzhou 4 with aft port of Tianhe
May (NET) - launch of Shenzhou 14 on CZ-2F/G
May (NET) - docking of Shenzhou 14 with nadir port of Tianhe
May (NET) - undocking of Tianzhou 3 from forward port of Tianhe for EOM & reentry
May/June (NET) - launch of Wentian on CZ-5B
May/June (NET) - docking of Wentian at forward port of Tianhe

After this it gets a bit murky as Tianzhou 5 operations appear to overlap with Tianzhou 4 but there seems to be no free docking port. Maybe TZ-4 will undock before TZ-5 arrives as it was scheduled (according to Twitter) to fly later, in Oct. 2022.

July? (NET) - undocking of Tianzhou 4 from aft port of Tianhe for EOM & reentry
July? (NET) or October - launch of Tianzhou 5 on CZ-7
July? (NET) or October - docking of Tianzhou 5 with aft port of Tianhe
July? (NET) - robotic relocation of Wentian from forward to starboard on Tianhe
August/September (NET) - Mengtian launch on CZ-5B
August/September (NET) - docking of Mengtian at forward port of Tianhe
September? (NET) - robotic relocation of Mengtian from forward to port on Tianhe
November (NET) - launch of Shenzhou 15 on CZ-2F/G
November (NET) - docking of Shenzhou 15 with forward port of Tianhe
November (NET) - undocking from nadir port & landing of Shenzhou 14
December? (NET) - undocking of Tianzhou 5 from aft port of Tianhe for EOM & reentry

Guess the thinking is that the next crew will not be launched if the pre-positioning of the cargo (supplies & experiments) for the next crew fails with the Tianzhou.


There isn't much storage space with the current station configuration minus the docked Tianzhou.


Also the Chinese don't appear to be planning on a Progress like logistics vehicle for more frequent supply missions to the station. So they are constrained by the number of station modules and logistics vehicles that can be build concurrently and be launched.

No.

Here is a moderator opinion from the region.
Base on information from picture below:
Mar 31, 2022 01:55:39.373  Tianzhou-4
May 14, 2022 09:22:31.693 Shenzhou-14
Oct 31, 2022 01:55:29.373 Tianzhou-5
Nov 17, 2022 09:22:31.693 Shenzhou-15

Judging from the SZ-13 date and the copy-and-pasted planned launch times, this graphic is very much notional and not to be relied on.

The original plan was to dock the cargo ship at the port on the left (according to the pictures below, but everything indicates that the ship was docked at the same port it was at).

At 23:55 UTC, China completed a redocking test on its Space Station, the test consisted of undocking the Tianzhou-2 cargo spacecraft from the forward port of the Thiane module and then moving about 200 meters away and finally docking at the same port.
These were tests to see how the docking systems work and how Thiane is doing before the arrival of the next module. Remote and crew-controlled docking inside Thiane was also tested.https://twitter.com/conexionspacial/status/1479663323415257088 (https://twitter.com/conexionspacial/status/1479663323415257088)

I found the first video really interesting. Very nice sleeping berths, each one has a porthole.
Most fascinating are the elastic bands built in the clothes (starting about 10:00 in the first video).
Do NASA/ESA/Roskosmos have something like that?

The modules are flight hardware given the protective remove before flight covers and streamers that say remove before flight. The engineering and ground test articles have grey metallic covers and flight spares also have red covers. Mockups generally do not receive such covers.

Interesting. I had no idea they were doing these kinds of full-scale fit checks with flight hardware.

China may not follow the same colour-coding conventions as others.

But regardless, the answer to "is it a ground test article or flight hardware?" is 'yes': The Tianhe module pictured is Tianhe-2, the backup to Tianhe-1 (so flight hardware), but is also being used as the ground test article - because if you need to build two anyway, may as well use it rather than warehousing it. There are tentative plans to launch it at a later date as part of a later phase Tiangong expansion.

China is taking a direct cue from the Soviet-Union (and later Russia) who did the exact same thing with the Almaz and Salyut space stations. As well as elements for the ISS (such as Rassvet and Nauka which were converted from ground test articles for SPP and the FGB).
Heck, even the USA did it. Space Shuttle Challenger was converted from the shuttle STA. It even happens with satellites. The IRAS IRX was converted from the development model. The ANS PFS was converted into the spare flight article in case the Scout launcher decided to have a bad day (which it did by the way but fortunately did not result in LOM, but that is another story).

Spacecraft covers are not nearly as universal as in commercial aviation. For example, the Ariane covers, plugs and tags are a rather nice purple rather than red!

Core module of China's space station achieves anticipated goal (https://english.news.cn/20220418/eea0bc270641424aa9e604a5e1bec9ab/c.html)

Tianhe, the core module of China's space station, has completed its verification of key technologies and achieved its expected goal.


Yang Hong, chief designer of the space station system of the China Manned Space Program at the China Academy of Space Technology, made the remarks at a press conference in Beijing on Sunday.


Yang said the core module has been in orbit for almost one year, and all missions have been carried out smoothly and according to plan, including rendezvous and docking with two manned spacecraft and two cargo spacecraft, as well as the three-month stay of the Shenzhou-12 crew and the six-month stay of the Shenzhou-13 crew.


Missions including extravehicular activities and manual remote operations were carried out in the past year.


Key technologies related to physical and chemical recycling and life support, large complex control, as well as large flexible solar cell wings and driving, have been verified.


Evaluation results show that Tianhe's current functions perform better than their design, Yang said.


Tianhe's recycling and life-support system has provided a good environment for astronauts' metabolism needs in orbit, Yang said.


Moisture discharged by astronauts is collected as condensed water, and urine is recycled and processed into drinking water and oxygen. Tianhe's water recycling efficiency is higher than 95 percent.


The amount of drinking water and oxygen that needs to be carried by cargo spacecraft has been greatly reduced thanks to the technology.


Large-scale flexible solar cell wings have been providing energy for the core module and its complex. The assessment showed that the solar cell wings have a power generation capacity approaching 10 kilowatt, beyond the expectations of their design.


Four extravehicular activities conducted by the Shenzhou-12 and Shenzhou-13 crews covered the operations, installation and maintenance of electronics, machines, pipelines and other typical equipment outside the cabin, and laid a solid foundation for astronauts to install and maintain extravehicular facilities during long-term operational periods after the completion of the space station, Yang said.


The robot arm played an important role in the whole key technology verification process and performed excellently. Its joint motion ability and terminal positioning accuracy met its design expectations. Its stiffness proved to be capable of lifting and transferring large loads, Yang said.


Since 2020, China has successfully carried out six flight missions, including the space station core module Tianhe, the Shenzhou-12 and Shenzhou-13 manned spacecraft, and the Tianzhou-2 and Tianzhou-3 cargo spacecraft, Hao Chun, director of the China Manned Space Agency, said at the press conference.


All six missions achieved success and completed their goal of verifying key technologies, Hao said.


According to schedule, China will complete the in-orbit construction of its space station by 2022. A total of six missions are planned for this year, including the launch of the Tianzhou-4 cargo spacecraft in May, the Shenzhou-14 manned spacecraft in June, the lab module Wentian in July, and the lab module Mengtian in October.


The three modules will form a T shape to complete the in-orbit construction of China's space station, followed by the launch of the Tianzhou-5 cargo spacecraft and the Shenzhou-15 manned spacecraft, Hao said.

Two lab modules to be central work area on China's space station (https://english.news.cn/20220417/b682e5d573f643c8b1bcbc23cca5dd2d/c.html).

The Wentian and Mengtian lab modules will be sent into space this year, and will become the central working area for astronauts in orbit after China's space station construction is completed, according to a press conference on Sunday.

Expert from China: It will be difficult for Russia to make launches at Tiangong.

Yang Yuguang: It will be difficult for Russia to launch to the Tiangong space station.

17:10 10.05.2022

BEIJING, May 10 - RIA Novosti. In the future, other countries will be able to send spacecraft to China's Tiangong Orbital Space Station, but Russia will face difficulties in launching ships due to the geographical location of the spaceports, said Vice Chairman of the International Astronautical Federation's Space Transportation Committee, professor at the China Aerospace Science and Industry Corporation (CASIC) Yang Yuguang.

According to him, in the future it may be possible to launch spacecraft to the Chinese orbital space station from other countries.

“Speaking of Russia , there is one factor that we must take into account. The territory of Russia is located at very high latitudes, and for docking with the Chinese space station, we have a basic requirement: the latitude at which the launch pad is located must be no higher than 42 degrees, this is the difficulty that Russia will face," Yang Yuguang said on Chinese TV channel CGTN on Tuesday.

At the same time, Yang Yuguang noted that the United States , Japan , as well as the EU countries that operate the Kourou cosmodrome in French Guiana , will not face such difficulties.

China's Tianzhou-4 spacecraft successfully docked at the Tiangong station on Tuesday. The truck delivered fuel, equipment, consumables and other cargo into orbit for the Shenzhou-14 crew of three, who will go to the Tiangong station in June this year and spend about six months there.

The construction of the Chinese multi-module orbital station Tiangong officially began on April 29, 2021, when the main module Tianhe was successfully launched into orbit. The construction of the station is expected to be completed this year. Three cosmonauts can be on the station at the same time, or six people during a crew change.

It is planned that the Wentian laboratory module and the Mengtian research module will dock to the station this year. In addition, in 2025, the autonomous astrophysical module "Xuntian" should be launched, which will periodically dock with the station for maintenance.

The main module of the station with a length of 16.6 meters and a maximum diameter of 4.2 meters was named "Tianhe", at the moment it is the largest spacecraft built in China . The control and management center and the main living space for the crew (about 50 cubic meters) are located here, and some scientific and technological experiments will also be carried out here.

In addition to the main module, living space is also provided in the experimental ones, so its total area will be about 110 cubic meters. The main module is equipped with two docking stations for experimental compartments, as well as three docking ports for docking manned and cargo ships.

Tianzhou-3 deorbit burns will happen after the launch and docking of Wentian Laboratory Module, so it will fly with Tianhe Core Module for at least one more week, not just few days. What jobs will the cargo spacecraft do during this period? Can it assist Wentian docking?

According to a post by CASC, the relocation of Wentian Lab Module from the forward to starboard port will happen ~1 month before the launch of Menttian. Wentian measures 17.9m in length, 4.2m in width. 50m^3 pressurized volume hosting 8 research racks, among which 4 belong to CAS..

1 probably to ACC, and the remaining 3 are probably empty shelves to host customer payloads.

Watch an interesting video: CSS Intelligent Induced Maintenance System. The video simulates the astronaut wearing AR glasses, and according to voice, animation and text guidance, initializes and unlocks the "mobile maintenance platform" of the Mengtian experimental cabin "online maintenance and adjustment operation cabinet MMW". *This MMW cabinet is in Mengtian, not Wentian's scientific glove box and cryogenic storage cabinet GCSR. These two cabinets look a bit similar, don't mix them up.

Mobile maintenance platform - expand the operating area, support large-load on-orbit maintenance operations, and carry out popular science education activities... MMW is a cabinet used to repair experimental cabinets. Astronauts cannot fully understand the maintenance of each hardware of the space station, so CAS/ CSU designed this intelligent induced maintenance system to help astronauts do their jobs easily. In the future, the system will also add a real-time expert system.

What should we call this in English?

Maintenance & Malfunction Workstation?
Mobile Maintenance Workstation?

"Designing objects to disintegrate upon atmospheric re-entry is becoming a priority for satellite operators. It's done partly by using materials which have low-melting point temperatures, such as aluminium.

In the case of rockets, this can be expensive, as historically the materials used for housing fuel, such as titanium, require very high temperatures to burn up. The sheer size of such objects is also an issue, especially in the case of the Long March 5, weighing over 25 tonnes."

I think they mean expensive, like the aluminum-lithium alloys used on later Space Shuttle external tanks, and similar structures. Fancy alloys are generally not easy to make or work with, increasing general cost.

I believe there are backup modules for each section, which is why there talks of phase 2 where the backup modules are used as expansion of the current station.

That's Mir!

Though it makes a change from them ripping off my model photos of the first Tiangong/Shenzhou and claiming it was the real thing and circulating to all the news agencies including the BBC.

One major problem of this program is there was too much officials talking that only ~15mins out of the more than 2 hours were actually for Taikonauts-African Youths conversations.

On the technical side, @CGTNOfficial used cheap text-to-speech software for part of the audio.

This is a capture from the video. 
I noticed that the feitian's backpacks are signed.
Till now the blue Feitian was weared by Tang Hongbo, Liu Buoming and Chen Dong.
The yellow one by Wang Yaping, Ye Guangfu and Liu Yang.

I don't read Chinese but comparing with the signed envelope that revealed the identities of the second group it seems that we have discovered a new chinese space tradition: the taikonauts sign their Feitians prior their spacewalk.

China Space Station: Shenzhou-14 crew completes second spacewalk

https://news.cgtn.com/news/2022-09-17/China-Space-Station-Shenzhou-14-crew-begins-second-spacewalk-1doOB1xqu4M/index.html

China's Shenzhou-14 astronauts, or taikonauts, began their second extravehicular activities (EVAs) on Saturday, according to the China Manned Space Agency (CMS).

Cai Xuzhe, the taikonaut who stayed inside the core module for support during the last EVAs, opened the airlock cabin of the Wentian lab module of the China Space Station at 1:35 p.m. Beijing Time. As of 3:33 p.m., Cai and Cheng Dong of the Shenzhou-14 crew successfully exited the cabin.

At 5:47 p.m., the Shenzhou-14 crew successfully completed the second EVAs, which lasted about five hours, CMS announced.

During the EVAs, the crew carried out operations including installing a foot-stop, which is used for fixing astronauts' feet on the robotic arm, and an assist handle, which can help astronauts open the hatch door from outside in an emergency.

The taikonauts also installed additional pumps, the core equipment of the space station's thermal control system, and carried out the most challenging task of extravehicular rescue for the first time.


EVA duration : 4 hours 12 minutes
