Re-docking of the Progress MS-17 spacecraft to the Nauka module

10/14/2021 10:14

On the night of October 21, 2021, in accordance with the flight program of the International Space Station, an operation will begin to re-dock the Progress MS-17 transport cargo vehicle from the Poisk small research module to the Nauka multipurpose laboratory module. All stages of redocking are planned to be carried out automatically under the control of cosmonauts on board the ISS and specialists of the Main Operational Flight Control Team of the Russian Segment of the ISS (Rocket and Space Corporation Energia named after SP Korolev, part of the State Corporation Roscosmos) in order to prepare module "Science" to receive the new nodal module "Berth".

The separation of the Progress MS-17 spacecraft from the small research module docking station, scheduled for 02:41 Moscow time on command from the Earth, will take place over the endless steppes of Mongolia. After undocking, the ship will retreat from the station and hover in anticipation of the calculated ballistic conditions for docking with Nauka. During 29 hours of autonomous flight, the "space truck" will make a series of corrective maneuvers, moving away from the ISS at a distance of up to 185 km. Docking of the spacecraft with the nadir port of the pressurized adapter of the Nauka module is planned for October 22 at 07:31 Moscow time using the Kurs automatic rendezvous and docking system.

The Progress MS-17 cargo vehicle should finally leave the ISS and de-orbit immediately before the launch of the Progress M-UM transport module with the Prichal nodal module. At the end of its mission, the "truck" undocked from the pressurized adapter of the "Nauka" module together with the adapter spacer, which currently provides docking of the Soyuz MS and Progress MS series transport ships. Thus, the "Science" module will have the possibility of regular docking with the arriving module "Prichal", which is expected to be launched at the end of November this year.

Russian cosmonauts get ready to use ERA manipulator during next summer’s spacewalk.

The ERA manipulator will be employed for relocating a radiator from the Rassvet module to the Nauka module.

11 NOV, 08:56

MOSCOW, November 11. /TASS/. Russian cosmonauts have for the first time ever practiced an operation simulating the transfer of a radiator from one module of the ISS (Rassvet) to another module (Nauka) with the European Robotic Arm (ERA) manipulator, the Gagarin Cosmonauts Training Center told the media on Thursday. The operation is to be conducted during extravehicular activity next year.

The Gagarin Center said that for the first time in its history cosmonauts, at different locations, were handling a single task, with part of the crew staying in a very special environment - under water.

"The tests will last for three weeks," the press-service said.

"The main crew of the ISS-67 expedition was the first to have coped with a new procedure of handling a common task, namely the relocation of a radiator. Cosmonauts Oleg Artemiev and Denis Matveyev were doing the job under water in the hydrolaboratory, and Sergey Korsakov, at the controls of the Don-ERA simulator. The crew’s actions were coordinated by specialists from the different departments of the training center," the Gagarin Center said.

Instructor Valery Nesmeyanov, of the center’s extreme training unit, said the cosmonauts coped with their task quite well.

"The crew confirmed the effectiveness of joint training and a very high quality of modeling a situation that may occur in real life. The experiment was a success. All specialists, including those from the space rocket corporation Energia, obtained unique knowledge crucial to making preparations for a real spacewalk," the Gagarin Center’s press-service quotes Nesmeyanov as saying.

The ERA manipulator will be employed for relocating a radiator from the Rassvet module to the Nauka module during the 67th ISS expedition next summer. The radiator’s function is to ease the impact of excessive heat on the Nauka module during science experiments. Two cosmonauts will be relocating the radiator in outer space, and a third crew member, operating the robotic arm.

Cosmonauts re-flashed the Science module before the arrival of the last ISS module.

Cosmonaut Dubrov flashed the Nauka module on the ISS before docking with the Progress spacecraft.

23:49 11/12/2021 (updated: 11:50 11/12/2021)

MOSCOW, November 12 - RIA Novosti. Russian cosmonaut Pyotr Dubrov changed the software of the Nauka multipurpose laboratory module (MLM) of the International Space Station before docking with the Progress spacecraft , which will deliver the Prichal nodal module (UM), follows from the crew's negotiations with the Earth , which are broadcast by NASA .

“Today we have successfully reflashed TVM (terminal computers - ed.) - one, two, and three MLMs for the version with UM, therefore we are ready for the further flight program,” a specialist from the Moscow Region Mission Control Center said to another cosmonaut Anton Shkaplerov .

The Nauka module docked to the ISS on July 29 after an eight-day flight. When the crew opened the hatch of the module, the Nauka's engines turned on unscheduled. To stabilize the ISS, the engines of the Russian Progress spacecraft were turned on, there was no threat to the crew.

The launch of the Progress M-UM cargo vehicle with the Prichal module is planned on the Soyuz-2.1b launch vehicle from the Baikonur cosmodrome on November 24. It is planned to be docked to the "Science" module on November 26. It should become the last module that Russia will introduce into its ISS segment.

Roscosmos told about possible experiments in the "Science" module soon

11/16/2021 03:10

Experiments in the multipurpose laboratory module "Science", which was docked to the International Space Station in the summer, may begin in the near future. Roscosmos cosmonaut Anton Shkaplerov, who is now on board the station, announced this in an interview with TASS.

According to him, while equipment elements are being installed in the module.

“I think that in the near future, when at least some of them are installed, we will begin the first experiments in the Science module,” said the agency's interlocutor.

In addition, the system for the regeneration of water from urine, installed in the module, may soon start working.

“I hope that in the near future we will launch it, and it will work, provide us with additional water for the station,” Shkaplerov said .

The Nauka module was launched from the Baikonur cosmodrome on July 21 and docked to the ISS on July 29. It is intended for the implementation of the Russian program of scientific and applied research and experiments, and will also provide cosmonauts with additional space for arranging workplaces and storing cargo, placing equipment for the regeneration of water and oxygen. With Nauka, Russian cosmonauts received a cabin for a third crew member, a second toilet and a European manipulator ERA, which will allow them to perform some work without going into outer space.

A slightly off track question butrelated to Nauka,

Can anyone tell that is the European Robotic Arm
Spare Elbow Joint currently on Rassvet still needed on ISS. I mean to say why is the ERA spare elbow joint needed on ISS when the actual ERA is arrived on ISS onboard Mauka Module

First image shows the ERA spare joint and second one shows the actual ERA

The answer to your question is in the word 'spare'. It is a spare part, in essence a replacement part in case the original part malfunctions.

Now that the actual ERA arm itself has finally arrived at the ISS, there is the possibility that at some point in its lifetime the elbow joint of ERA becomes damaged or inoperative. When that happens the elbow joint of ERA can be replaced by the spare elbow joint that is stowed on the MRM.

ERA is designed to be repaired on-orbit. If, for example, one of the two wrist joints malfunctions, it can be replaced with a spare unit. Same for the elbow joint. Crews on ISS can even swap out the computers on ERA for replacement ('spare') units. Same for the CLUs.

To be more precise: The spare elbow contains the spare control computer (ECC). There is not a separate spare ECC. The ERA spares set consists of the three EVA Replaceable Units (ERUs):
Spare Wrist + End Effector
Spare elbow joint + limbs + ECC + Elbow Joint Electronics
Spare camera and lighting unit (CLU)

The Spare Wrist and Spare CLU are still on the ground and will only be launched (by Progress AFIK) when needed.

The beginning of a new "era"

12/11/2021 15:30

The European Robotic Arm (ERA), installed outside the multipurpose module "Science", has expanded the arsenal of robotic equipment at the International Space Station. Igor Afanasyev tells about the features of the manipulator, its similarities and differences with the Canadian and Japanese "colleagues" in the magazine " Russian Space ".

Controlled via laptop

The European robotic "arm" ERA, manufactured by the Dutch branch of Airbus Defense and Space and installed on the Nauka module, will complement the attachments of the Russian segment of the station, which include two Strela cranes, which were previously located on the Pirs, and then moved to the modules. Search ”and“ Zarya ”.

It is ERA that will soon become the main mechanized astronaut assistant on the outer surface of the ISS. She will have to install, remove and replace equipment outside the station, including removing it from the Russian airlock. In particular, it is with his help that an airlock and a heat exchanger, which are already on the ISS, will be installed on the Nauka module.

The manipulator will also be able to survey the ISS using video cameras and accompany astronauts during extravehicular activities.

ERA will be the first robot capable of "walking" on the outside of the Russian segment of the ISS, "walking" between the fixation points on the modules "Nauka" and "Prichal". The control system enables the robot to "walk" independently, moving from one attachment point to another.

The manipulator, which has an extended length of 11.3 meters, consists of two symmetrical long sections, connected by a hinge, and two "wrists". True, instead of brushes, there are so-called EES (End Effectors) at the ends - elements that the "hand" uses to hold the station, grab cargo and help astronauts, including moving them between work sites.

"Joints" provide the manipulator with very high mobility; it can reach objects at a distance of 9.7 meters and carry eight-ton weights at a speed of up to 10 cm / sec and with a positioning accuracy of up to 5 mm. In this case, the weight of the hand itself is only 630 kg.

Four cameras, lighting units and electronics allow to control the work of the "hand", and it will be possible to control it both from inside and outside the station. The manipulators already on the ISS do not have such capabilities.

ERA will give the crew more freedom and flexibility in their operations, said David Parker, director of research for human-machine systems at the European Space Agency.

By the way, the European "hand" is the only manipulator on the ISS that can be operated manually without using joysticks. Its actions are built in automatic mode - on the basis of commands given by astronauts from control panels, which are located both inside and outside the station. In theory, in the future, not only astronauts, but also operators from Earth will be able to transmit commands. This control option has not yet been implemented.

Charlie Chaplin

Development of the European space manipulator began in 1985. Fokker Space conducted research for the Hermes mini-shuttle program, which the European Space Agency was then working on. As a result, a project of a robotic arm for HERA (Hermes Robotic Arm) appeared - a scaled-down analogue of the Canadarm manipulator used on American shuttles to move cargo in space.

After the cancellation of the Hermes program in 1992, the European and Russian space agencies agreed on the possibility of installing HERA to service the Mir-2 space station under development, and the manipulator received its current name ERA. It was then that a control computer and two new control panels were added to the "arm" - one for the cosmonaut in open space, the other for the crew inside the station.

With the cancellation of the Mir-2 project and the start of work on the ISS, the project was adapted to the Russian segment of the international station, about which a corresponding agreement was signed. As the configuration of the segment was changed, the manipulator in the drawings “wandered” from module to module. Full-scale design began in 1998 in conjunction with the Russian Science and Power Platform (NEP), a module that was initially supposed to be manufactured for the plant.

ERA's first mission would be to install solar panels. The platform was planned to be launched in 2001 on the American shuttle, then the launch was postponed to 2002. After the death of "Columbia" (02/01/2003), it was postponed indefinitely, and then the NEP project was canceled altogether.

In 2004, work resumed: it was decided to install ERA on the module, which was later named "Science". A corresponding agreement was again concluded with the Europeans. Testing of one of the manipulator models has begun under conditions that simulate weightlessness. The structure attached to the model of the Nauka module was immersed in water in the hydro laboratory of the CTC, where the cosmonauts trained with it.

In addition to the above model, two more were used during testing. The first is to determine the geometric compliance of the ERA with the footprints at launch, the second is for vibration resistance tests in the launch configuration.

In 2005, ESA signed a contract with Airbus Defense and Space to prepare the ERA for launch with Nauka on a Proton-M rocket in November 2007. In February 2006, equipment for training astronauts to work with a manipulator arrived in Russia. In the meantime, the launch of "Science" was repeatedly postponed, and with it the delivery of a flight copy of the ERA to Russia was postponed. In addition, the development of the "hand" also proceeded not without technical and software problems. Only in May 2020, the ERA arrived at Baikonur, and a year later the manipulator was installed on Nauka.

When launched in July this year, the ERA was attached to a small diameter zone of the module in a configuration called "Charlie Chaplin": the shoulder segments are parallel and adjacent to each other, and both end effectors, in contrast, are spread apart like the ends of a great comedian's boot. The movable segments of the "arm" were fixed with special hooks for the seats on the surface of the "Science". The astronauts will free them by going out into outer space.

Many-armed Shiva

ERA is far from the only manipulator aboard the ISS. The station is equipped with several more robotic "arms" that perform similar functions.

The first, and most famous, is the US-segment Canadarm2 mobile service system. It consists of three parts: a mobile base cart, a lifting arm and a two-handed Dextr gripper for delicate work on the outside. The system can be moved on rails on trusses using a trolley.

Comparing Canadarm2 and ERA is quite difficult, since they differ noticeably in tasks and capabilities, although they are similar in appearance.

So, Canadarm2 is much larger (maximum length is 17.6 m), more powerful (capable of handling objects weighing up to 116 tons, for example, a shuttle) and heavier (dead weight - 1170 kg). This manipulator serves, among other things, for "picking up" and docking with the ISS modules and ships from different countries that do not have an active docking system. At the same time, both "hands" can independently "travel" along the surface of the station from point to point, perform maintenance and inspection, move loads, and also help people while working in outer space.

Since the Canadarm2 grips are not compatible with the rigging knots on the Russian segment, it cannot be used on Russian modules, with the exception of the Zarya. Thus, due to the difference in interfaces, Canadarm2 can only work with the American segment, and ERA - only with the Russian one.

Unlike the fully automatic ERA manipulator, Canadarm2 can be operated either by an astronaut on board the ISS or by a ground crew operator at NASA headquarters.

The Kibo module is equipped with a Japanese manipulator JEM-RMS (Japanese Experiment Module, the Remote Manipulator System), which uses the same grips as Canadarm2. This "arm" is used exclusively for work on the Japanese module: it was mainly used for loading and unloading platforms for exhibiting samples and scientific cargo arriving in the automatic "truck" HTV "Konotori".

Thus, ERA will harmoniously complement the ISS family of robotic manipulators, increasing the functionality of the Russian segment. The primary tasks of the "hand" for the first year of work at the space station: installation of a large radiator and an airlock on the "Science" module, as well as the installation of a mobile workstation.

In perspective

The head of the space flight center of the Rocket and Space Corporation Energia, Alexander Kaleri, said that three spacewalks would be required to install the ERA manipulator. They will be attended by European astronauts Matthias Maurer and Samantha Cristoforetti. They will arrive on the ISS in October of this year and in April of the next, respectively.

During the Russian exits in January 2022, the cosmonauts will remove the thermal covers and fasteners from the robot. In the future, the manipulator will be tested and put into operation. 

“ESA is looking forward to starting work with the ERA manipulator,” Philip Schonejans, ERA project manager, told Russkiy kosmos . “The manipulator will not only be a useful addition to the robotics used on the ISS. Operating with ERA will also allow us to expand our overall robotics expertise, which is critical to our space exploration program. ”

Work continues on the module "Science"

08/03/2021 10:38

The integration of the Nauka multipurpose laboratory module with the Russian segment of the ISS continues on board the International Space Station. During the week, Roskosmos cosmonauts Oleg Novitsky and Petr Dubrov will carry out work to unload the module and dismantle the equipment that has arrived on it.

In addition, the Russian crew members of the 65th long-term expedition are beginning to prepare for the upcoming spacewalks. The next ones are tentatively scheduled for September 2 and 8, 2021. They will focus on the integration of the new Science module on the outside of the International Space Station.

The very integration of the new module into the station will take more than six months and will require about ten spacewalks of Russian cosmonauts. During this period, cable networks and pipelines will have to be laid, the means of fastening large-sized objects, as well as an airlock and a radiation heat exchanger, which are currently located on the Rassvet small research module, will be installed.

The next operation associated with the Nauka module is the re-docking of the Yu.A. Gagarin "(" Soyuz MS-18 "). According to preliminary data from the ballistic and navigation support service of the TsNIIMash Flight Control Center (part of the Roscosmos State Corporation), the ship's undocking from the Rassvet module and docking with Nauka are scheduled for September 28, 2021. By re-parking, Soyuz MS-18 will free the docking station for the Soyuz MS-19 spacecraft, which is scheduled to launch on October 5.

The radiator and airlock were launched on MRM Rassvet.

He's probably referring to the SKKO. And to try to answer Chinakpradhan's query: my guess is it's a foldable or assemblable structure that won't be brought up in as large a configuration as depicted. Indeed it seems to be made up of four (?) rectangular pallet-like modules that can probably be brought up in one or several regular Progress flights. But I have no actual insider's info, so anyone with better sources can chime in to shed light on that component.

yes !! I used means of fastening large-sized objects for skko only. But I doubt it being still on ground! As the module has made so many years in the making, it may have been launched with nauka directly. (Also I don't know if rondaz was write or wrong to say ТГК as cargo freighter, as google translated it as TGK.)

Besides it is a relatively flat structure and so it cannot need a separate launch, due to not fitting inside a payload fairing, like the airlock would have needed.  To get a clarification that will it be transported by a progress  or not, do we have a image of nauka's aft (along iss direction) or zenith (along module direction), that is specifically the side has the porthole, so that we can know if it is already on nauka or not?

thing is which progress can even transport it, as nasapaceflight iss calendar tells the installation in vkd 58 spacewalk in August 2022 (sans delay).

 After research, I have got some sources. But, I cannot find even whether this being transported by progress or was on nauka with launch (definitely not on rassvet). This is because:

They are on anatoly zak's site shown on the article: https://www.russianspaceweb.com/iss-fgb2-mlm-integration.html and his latest
https://www.russianspaceweb.com/protected/mlm-era-activation.html#2022_0124

But that requires money of $50. I would tell if someone, who has subscription and works on nasapaceflight, he can only answer that what is inside those links on these websites. So until VKD 58 spacewalk details are freeily published, this matter remains open as I asked many including anatoly zak, but they hesitated to answer.

yes means of fastening large-sized objects is skko only. But I doubt it being still on ground. As the module has made so many years in the making it may have been launched with bauka directly. (Also I don't know if rondaz was write or wrong to say ТГК as cargo freighter as google translated it as TGK)

ТГК = транспортный грузовой корабль (transportny gruzovoi korabl', or cargo transport craft). By the way, it can refer to any VV, not just Progress. If SKKO had been launched with Nauka, it would have been noted as such in the graph, which was uploaded shortly before the MLM launched, so should be current.

The "opposite" side of Nauka (facing aft towards Zvezda, side with the porthole) is where ERA is currently stowed, so it would not be easy to see anything that might be stowed under it even if pictures were available, which they're not, since no unobstructed views forward exist from Zvezda. However, it is reasonable to believe the SKKO is not installed precisely because ERA is taking its place. Indeed, in pre-flight assembly pictures there is no obvious structure underneath ERA as it was being installed. Once the arm is activated and moved to its grappling locations (currently protected by the four orange covers seen in most on-orbit pictures) the area will be clear.

I really doubt it will be installed in August given the ERA activation procedures are going to take longer than initially planned (VKD-52/53 going from Feb->April, so we could be looking at a VKD-58 delay to at least October). Regadless, there are at least 2 Progress missions between now and then (MS-19 and -20, and perhaps -21 if VKD-58 gets delayed). If for some reason SKKO wouldn't fit through the RS hatches, there are also Dragons (or HTV-X, but that's delayed to next year due to H3) which could take it up as pressurized cargo - although I believe that to be unlikely.

PS: Please use punctuation: it's really difficult to disentangle where a sentence begins/ends or when you're asking something in your posts.

The "opposite" side of Nauka (facing aft towards Zvezda, side with the porthole) is where ERA is currently stowed, so it would not be easy to see anything that might be stowed under it even if pictures were available, which they're not, since no unobstructed views forward exist from Zvezda. However, it is reasonable to believe the SKKO is not installed precisely because ERA is taking its place. Indeed, in pre-flight assembly pictures there is no obvious structure underneath ERA as it was being installed. Once the arm is activated and moved to its grappling locations (currently protected by the four orange covers seen in most on-orbit pictures) the area will be clear.

I really doubt it will be installed in August given the ERA activation procedures are going to take longer than initially planned (VKD-52/53 going from Feb->April, so we could be looking at a VKD-58 delay to at least October). Regadless, there are at least 2 Progress missions between now and then (MS-19 and -20, and perhaps -21 if VKD-58 gets delayed). If for some reason SKKO wouldn't fit through the RS hatches, there are also Dragons (or HTV-X, but that's delayed to next year due to H3) which could take it up as pressurized cargo - although I believe that to be unlikely.

Just if you can help me. Can you show which graph are you saying ?? Is that nauka structure diagram by nasa?? If it is that, then that's a bad one as it even do not show era portable workpost. Plus I need to say that it is a unpressurized thing so we can have progress like progress m 14 and 38 that were modified to carry vdu propulsion units. So sir please show the graph once so that things would be clear.

The radiator and airlock were launched on MRM Rassvet.

He's probably referring to the SKKO. And to try to answer Chinakpradhan's query: my guess is it's a foldable or assemblable structure that won't be brought up in as large a configuration as depicted. Indeed it seems to be made up of four (?) rectangular pallet-like modules that can probably be brought up in one or several regular Progress flights. But I have no actual insider's info, so anyone with better sources can chime in to shed light on that component.

yes means of fastening large-sized objects is skko only. But I doubt it being still on ground. As the module has made so many years in the making it may have been launched with bauka directly. (Also I don't know if rondaz was write or wrong to say ТГК as cargo freighter as google translated it as TGK)

Besides it is a relatively flat structure and so it cannot need a separate launch due to not fitting in payload fairing like the airlock would have needed to get a clarification that will it be transported by a progress do we have a image of nauka's aft (along iss direction) or zenith (along module direction),that is specifically the side has the porthole, so that we can know if it is already on nauka or not.

thing is which progress can even transport it as nasapaceflight iss calendar tells the installation in vkd 58 spacewalk in August 2022 (sans delay).

Cross post:
GT: A little more than two weeks remain before the launch of the #ProgressMS19 spacecraft to the ISS.

White heavy check mark We tell in detail what the new “truck” will bring to the astronauts: https://roscosmos.ru/33916/

In addition to standard cargo and experiments, six small spacecraft will be delivered to the station.

https://twitter.com/roscosmos/status/1486990604831756290
this tells progress MS 19 won't transport any modular part. It is probably due to era activation and nauka outfitting delays. it can happen that the module will arrive after nauka outfitting by a single progress or multiple progress . Also this can be done at any time like irosa installation so I also now don't believe the timeframe to be immediately after outfitting  installation.

@eeergo: just a simple doubt.
http://www.russianspaceweb.com/protected/iss-vkd59.html , the main subsription article on "Means of Attachment of Large Payloads, SKKO" has arrived yesterday, the VKD-59 spacewalk. But, in huge despair, the only info available to us are
"The integration of the newly arrived Nauka module with the rest of the Russian ISS Segment will be completed with the VKD-59 spacewalk aimed to install a special pallet for scientific instruments on the module's exterior. It will be the 11th spacewalk to fully configure Nauka for operations in orbit." and the image below.

 can anyome help out or through someone who has anatoly's subscription to confirm which of the three is a right option. i dont need anything more from that article but a ans to this small question

The Means of Attachment of Large Payloads, SKKO is:
1)still on ground and will be transported to ISS by a spacewalk
2) it is already on ISS, transported by a earlier progress spacecraft (in this case please mention that progress to me)
3)it was transported to ISS with Nauka, itself only
please help me out in this anyone

2) it is already on ISS, transported by a earlier progress spacecraft (in this case please mention that progress to me)
3)it was transported to ISS with Nauka, itself only

Option 2:

2021
18 - October 28 (301:00:00:32.525) – Progress MS-18 (№447) – Soyuz-2-1A (С15000-049) – Baikonur 31/6

SKKO launched folded accordion style like a retracted ISS radiator. Once the nadir end of SKKO is soft docked to Nauka and bolted down, the launch locks on SKKO will be released by the spacewalkers to allow it to be unfolded and extended with its joints self locking in the extended position to create a rigid frame. Then the Zenith end of SKKO is soft docked to Nauka and bolted down. The 3 passive payload adapters and the one active payload adapter (i.e. active remote sensing payload like MIR Priroda's Travers Synthetic Aperture Radar) are then outfitted. The SKKO is derived from the setup used on the Priroda module.
