Korea Aerospace Research Institute has selected SpaceX (USA) as a launching service for the Korea Pathfinder Lunar Orbiter (KPLO), which will be launched in 2020
...
The launch will be the Cape Canaveral Air Force Base in Florida, USA.

Antexis of India participated in the open bidding for the trial lunar launch service.

The company chose Space X as the preferred bidder through the evaluation and negotiated the final contract on the 15th.
...
The Korean lunar orbit line is 550kg.

If anyone sees more information about this please post a link

edit: saw a couple more Korean sources saying the same thing.
Emily Lakdawalla had a recent story on the project with more information, she says the target date is Dec. 2020:
[The Planetary Society] South Korea's first lunar mission planned for 2020 (http://www.planetary.org/blogs/emily-lakdawalla/2017/1207-koreas-first-lunar-mission.html)

I have a PDF of a KPLO PI's presentation in October. A NASA official also told a Planetary Society reporter that the launch was more specifically scheduled for December 2020 as of a few weeks ago, but it may still be in flux, so I wouldn't put too much weight on that date.

There might be a delay of the Korean Pathfinder Lunar Orbiter launch by @SpaceX falcon 9 in December 2020.

Likely now to be 2022. The interview quote in the tweet attachment is quite something ...

Quote
"Although we kept pointing out that the design was impossible for the mission since last year, the satellite chief or the project manager failed to properly deal with the problem. Administrations related to the KPLO mission have also failed to come up with effective measures due to lack of expertise and experience."

They added a link to a news story (although it's not the one in his first tweet).  I'll make it NET 2021 for now.

They're worried about mass increase from 550kg to 678kg, but I think a reusable Falcon 9 can send much more than this to TLI? Not sure what's the concern.

The worry can be on their part as if the mass increase is an increase in dry mass, the spacecraft will have quite less delta v, which means lower lifetime.

South Korea's first lunar probe mission, formally known as the Korea Pathfinder Lunar Orbiter, has been named "Danuri," the Ministry of Science and ICT said Monday.

Danuri is a combination the two Korean words "dal" and "nuri," meaning moon and enjoy, respectively. According to the ministry, the name expresses a desire for the country's first moon mission to be successful, and for the probe to enjoy everything that the moon has to offer.

The Korea Pathfinder Lunar Orbiter is on its way to Cape Canaveral. The launch is targeted on August 2nd UTC by SpaceX's Falcon 9.

Korea's first challenge towards a farther space The Danuri, Korea's first lunar probe, finished production and inspection, and started transporting it to the launch site today (5th). Danuri is scheduled to be launched on August 3, 2022 after being transported and preparing for launch for about a month at the launch site.

Cross-post; my bold:
KPLO/Danuri, launching on August 2 UTC, is said will use a booster already recovered 5 times. 1067.6, if recovered successfully on July 15, likely will not be ready.  That would make 1052.6 the first stage for Danuri.



Will KARI pay for a Static Fire?  Otherwise, I presume that there will be none.

680 Kg to 300 km LEO should allow for a RTLS landing. 

Those are great to watch and really help the SpaceX turn around.

Why only 300km?

Quote
After the launch, the Danuri team will cooperate with the US' National Aeronautics and Space Administration to follow a ballistic lunar transfer to enter the moon's 100-kilometer orbit by December.

Is 300km
a) perigee?
b) a parking ~circular orbit prior to Falcon changing to an elliptical orbit ?
c) a ~circular orbit for separation then Danuri does all the work of going to TLI?
Edit: d) something else (like altitude at separation though that probably shouldn't be described as a 300km orbit)


If c) why not get Falcon to do more of the work?

A launch of KPLO is scheduled for 1 August 2022 on a SpaceX Falcon 9 Block 5 vehicle from Cape Canaveral, Florida into a 300 km Earth orbit, followed by a translunar injection burn and a one month lunar transfer phase.

KPLO uses a WSB/BLT transfer but still needs a TLI.  See Belbruno and Carrico, "Calculation of Weak Stability Boundary Ballistic Lunar Transfer Trajectories", https://astrogatorsguild.com/wp-content/papers/0800_wsb.pdf

The question remains how the mission evolved to underutilize so remarkably the capacity of the launcher.
One logical possibility is that this was the limit at the time the mission was designed.
It is possible that it was originally a rideshare, limiting the orbit to which it could be carried.
With the other passenger no longer on the vehicle, KPLO could be sent to an orbit with a higher apogee and perigee velocity, which would reduce the delta-V required for the TLI.
But KPLO has the fuel to accomplish the mission as originally planned with some margin. 
Under-fueling would represent a trivial savings, and would require the optimization of the new, shorter TLI burn.

We had a saying: "Less is more.  More is more.  Keeping things the same is more if you debate forever."
We were talking about cost.

Staying wary of Feynman's quote ("You're not thinking.  You're just being logical.") a good guess is that more launcher capacity was freed up, but there would be cost involved and nothing necessary to gain by re-planning the mission, so that capacity will be ignored.

Going back to the original NASA AO for KPLO instruments, the spacecraft mass was 550 kg into TLI https://www.nasa.gov/feature/kplo-ao .  When the mission was designed, it seems KARI was still hoping to use their own rocket (KSLV-II) as the LV.  By the time F9 was selected in early 2018, it was apparently not possible to change the spacecraft design very much (there's been some tankage/fuel increase but only 100 kg-ish), and the F9 second-stage can't provide delta V for the spacecraft to slow down to get into lunar orbit because it doesn't have the operating duration to do so (I presume.)

That said, I don't know what the maximum F9 injection mass into TLI is.

An efficient Hohmann transfer injection would require a speed up rather than a slow down to get into lunar orbit? Gravity of moon complicates things so I could easily be wrong and a slow down is needed?

Do we know where the falcon second stage is going?

Can Stage 2 do a translunar injection as its second burn after coasting in LEO?

Or will Danuri raise its apogee over time similar to CAPSTONE/Photon?

While the quote from the link doesn't say whether the TLI burn is done by Falcon or Danuri, I think other parts of the linked page make it clear it will be Falcon doing the TLI eg

Quote
To successfully deliver KPLO to the Moon, the spacecraft is designed to have a four Orbit Maneuver Thruster (OMT), with approximately 31.8 N of thrust with 227 s of Isp (specific impulse) for large burn execution, and eight Attitude Control Thruster (ACT) with approximately 3.48 N with 218 s of Isp for small burn execution. All of these engines will be clustered for burn executions. Four OMT engines will be clustered to be used for the main thruster set for large burns during the transfer and LOA phase

Depends on which reference frame you're talking about, no?  In the earth frame I'm sure you're right and my language was sloppy.  In the lunar frame it's a slowdown; see https://koreascience.kr/article/JAKO201635542397762.pdf figure 2.

I don't know where the Falcon 9 second stage will end up; I expect it will remain in the initial injection orbit unless they do a burn to depletion after spacecraft separation.

It might also depend on what sort of TLI you are doing. I was thinking with a hohmann transfer it would be a speed up but if you were talking about KPLO WSB/BLT then it could well be that a slow down is needed: The ideal WSB/BLT would need very little, perhaps even 0 delta_v at LOA?

For small burns, such as for TCMs less than 10 m/s, momentum dumping, and orbit maintenance during the nominal mission phase

Not sure if that 'momentum dumping' is for lunar orbit acquisition(LOA) or just for lowering orbit once in lunar orbit.

Changing the frame of reference could cause different use of language, but this probably just us talking about different TLIs rather than different frame of reference?

“Momentum dumping” usually refers to desaturating momentum wheels.
That is, due to force imbalances, one or more momentum wheels used for pointing and attitude maintenance and adjusting, will soak up momentum, that is rotate faster and faster, until they approach their limit. At that point they are considered “saturated”. Applying a torque in the opposite direction allows the wheel to slow down or “desaturate”.
The goal is to do that without changing the trajectory. 
So it’s not associated with LOA, etc.

If it's being left in the initial injection orbit it could end up anywhere as WSB transfers are by definition chaotic so even post-shutdown venting could wildly change the resultant trajectory. It could end up crashing into the moon, the earth, or shooting out into solar orbit.

Interesting that even though this is a very low-mass spacecraft as discussed upthread, this is not an RTLS flight.

Probably need enough delta-v for TLI, hence the drone ship landing.

Mass to a C3 of -1 is about 1500 kg for RTLS according to the graphs upthread, and KPLO masses less than half of that AFAIK.

One possibility is that SpaceX needs to do this to avoid crushing the spacecraft.  Merlin vacuum is about 981kN, and throttles to 64%, or about 628kN.  The end-of-burn mass of the stack is something about 4.5t empty second stage + 1000kg reserves (1%) + payload, or about 6060kg in this case.  So the acceleration would be more than 10 Gs.  With an ASDS landing, however, the payload is about 3400 kg, so they end the burn with an extra 2800 kg of fuel in the tank, and reduce the peak acceleration to about 6.3 G.

Could be, thanks.  Falcon 9 user's guide gives a peak acceleration of 8.5g for "light" payloads (<4000 lbs) but cautions

for ultra-light payloads (~2,000 lb or less), coordination with SpaceX mission management is required, since these load factors may not be adequate to design the payload.
I'm sure the cost required to add ballast mass or find a secondary payload was more than the extra hassle of an ASDS landing.

Adding ballast mass, or a secondary payload won't help.  If they are heavy enough to reduce the acceleration by much, they are also heavy enough to require an ASDS landing.  You may as well let the ballast be extra fuel, which needs no engineering, gives increased margins, and ensures the stage has plenty of dV to re-enter.

I guess I'm not following exactly what the stated capability of 1500 kg to C3 of -1 for RTLS means then, but I'm sure I'm just missing something.

Perhaps you mean that even 1500 kg of payload is not really practical because the acceleration would be too high?
Title: Re: SpaceX F9 : KPLO : CCSFS SLC-40 : 4 August 2022 (23:08 UTC)
Post by: LouScheffer on 07/30/2022 07:06 pm
It depends on how much reduction in acceleration the payload needs.   If you add enough ballast to get to 1500 kg, you bring the peak acceleration down to 9 Gs.  That's as much reduction as you can get while still keeping RTLS.  If you need more reduction than that, the amount of ballast required will require an ASDS landing anyway.

So there is a window where ballast can help reduce the peak acceleration while still doing RTLS - say the spacecraft is designed for 9.5 Gs.  But since they are doing ASDS I'm guessing they are not in that window.

I don't believe we've seen a NOTMAR for second stage re-entry, though. Normally when there's a controlled re-entry burn planned, it gets announced at the same time as the first-stage recovery zone.

Pure speculation: Might be interesting to deploy the primary mission and then use the extra fuel to get additional F9S2 BEO flight data. Might be why the Tesla promo thing is on this flight particular.

This makes sense.  It's almost at Earth escape already - just add a little dV and dispose of the stage in solar orbit.  With such an eccentric initial orbit, this may be easier than plotting an accurate controlled re-entry.

SpaceX is targeting Thursday, August 4 for launch of KPLO to a ballistic lunar transfer orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous launch window is at 7:08 p.m. ET (23:08 UTC), and a backup launch opportunity is available on Friday, August 5 at 7:00 p.m. ET (23:00 UTC).
The Falcon 9 first stage booster supporting this mission previously launched Arabsat-6A, STP-2, COSMO-SkyMed Second Generation FM2, and two Starlink missions. After stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.
A live webcast of this mission will begin about 15 minutes prior to liftoff.

I think SpaceX got the SECO-1 and landing burn startup milestones mixed up.

There’s no way a landing burn would last one minute, and typical landing burns go from 25 to 33 seconds.

So, subtracting 9:01 from 8:33 is 28 seconds, which is a reasonable landing burn length.

Plus, it makes sense for SECO-1 to be at 7 minutes, 58 seconds since Danuri is a light payload.

More than normal IMO, probably humidity during launch.
Very nice display as the pieces that drifted ahead of the rocket came rushing back up just before the reentry burn, due to lower aerodynamic coefficient.

Top left leg looked wobbly before cut out.
EDIT: some background noises from the audience
EDIT2: but, confirmation nevertheless!

To be precise, the background noises (ooohs and aaahs) were heard after the video cut.  Also what we saw on video did not warrant oohs and aaahs.  Conclusion - they saw the fun parts, or some data that we don't see.

Definitely the top left leg deploy had a bounce to it, and we know the rocket ended up off center.

Could have been a bounce after touch down, or could have been that the odd deploy had something to do with last-second guidance.

I calculate a non-Sun affected apogee of 1,687,814 km.

Enter initial perigee height (km): 250
Enter SpaceX speed (km/h): 37875
Enter initial orbit inclination (deg): 28.5

Estimated inertial speed = 10945.6 m/s
Estimated apogee height = 1687813.9 km

The Chinese carried out the second launch of the CSSHQ spaceplane in secret, and I should emphasize that the KPLO launch and NROL-199 launch were slightly delayed by a few days, so it is an unexpected coincidence for the five launches to happen in a single day.

When people at Hawthorne go oohhh ahhh for a landing it's almost always because the feed got cut which, as it turns out, it's what happened. They have other feeds but if they don't have signal neither from booster nor droneship you can bet the other feeds ain't working either so they don't see anything at all, wrong or bad, hence the moaning (because just like us, they also like to see the landing)

This is fun conjecturing, psycho-deduction and all :)
I'm sure the video feed to them and to us is the same feed, and was lost at the same time.
They may have a data feed though that's intuitive to read in real time.

I'm saying thid because I'm pretty tuned in to the oohs and aaahhs during the web casts and I am pretty confident this time around they were very pronounced compared to regular feeds.
Shrug.
I think we've heard all there is to hear about this launch.  All's well that ended well.

I'm sure that's true for the "peanut gallery" audio we hear in the background audio from Hawthorne.

However, it's worth pointing out to for the benefit of those less knowledgeable that the loss of video can be due to numerous factors that can interfere with high-rate signals necessary for video, while lower data-rate telemetry continues to come in just fine.

I'm just saying what's basically been the norm for the past 60 successful consecutive landings where the people out there at Hawthorne have gone oohhh ahhh multiple times and speculation has come out from the public saying the booster is dead and then boom, it's there, on the droneship, just fine. Not always that they go oohh ahhh and moaning and such it means something's going wrong... that's my whole point.

I'm in agreement in general, yes.

I was saying that for whatever reason, this one caught my ear.  The human mind is a wondrous and confused organ, mine doubly so.

And this happened (to my ear) in real-time, before seeing the off-center landing image, so, hmmm.

Also listen carefully to the narrators before and after loss of signal.

Sure.

But always remember who reads these posts: not everyone is an engineer, or deeply-versed in how telemetry datastreams work. Everything written as an unqualified statement eventually gets picked up and quoted (or worse, just referred to as "I heard ...") without context.

SO: to be abundantly clear to those who don't realize, the audio "Ooohs and Aaaaaahs" are background noise during the webcast. They are not launch controllers nor even anyone in the launch control room. They are just reacting to the lack of video signal.

The controllers on-console may - and perhaps in many case DO - know more than those making noise in the background, and they know more than the launch commenter, at least until that person has time to look at internal data or hear comms we - the audience - cannot.

Lots of ice chunks, right?

That’s common but did you notice at SES-1 that when the stiffening ring comes off the MVac engine bell lip it flies right towards the Sun, and it’s tumbling shadow falls back on the engine bell.

That I have not seen before.

Jami's working pretty hard to get each feed, tweaking the forward error correction thresholds on the RF and UDP/IP stuff.

Sometimes to get the sync better for each camera, they use less error correcting buffer to reduce latency. The consequence though is if the signal gets too weak, they simply have no useful decodable data.

BTW, huge props to this forum for getting the first droneship landing footage to a usable state.

Don't you miss the good old days when lunar transit times was three days?

I do. I wonder if it takes more delta-v to do a three-day transit.

It would take more dV for the payload - the webcast discusses the tradeoff in some reasonable level of detail at the 9m45s mark:

NASA’s ShadowCam Launches Aboard Korea Pathfinder Lunar Orbiter

NASA Posted on August 4, 2022 8:09 pm

NASA’s ShadowCam is heading to the Moon aboard Korea Aerospace Research Institute (KARI)’s Korea Pathfinder Lunar Orbiter (KPLO) mission. KPLO, also known as Danuri, launched at 7:08 p.m. EDT on a SpaceX Falcon 9 from Launch Complex 40 on the Cape Canaveral Space Force Station in Florida on August 4.

Developed by Arizona State University and Malin Space Science Systems, ShadowCam is one of five instruments on board KARI’s KPLO spacecraft.

A hypersensitive optical camera, ShadowCam, will collect images of permanently shadowed regions near the Moon’s poles. This will allow ShadowCam to map the reflectance of these regions to search for evidence of ice deposits, observe seasonal changes, and measure the terrain inside the craters. The ShadowCam instrument was designed based on previous imagers like those found on the Lunar Reconnaissance Orbiter, but it is several hundred times more light-sensitive to allow for capturing details within the permanently shadowed regions.

The data gathered from ShadowCam and the other KPLO instruments will support future lunar exploration efforts, including Artemis. The high-resolution imagery captured in extremely low-light conditions could help inform landing site selection and exploration planning for future Artemis missions by providing insight into terrain and lighting conditions, and the distribution and accessibility of resources like water ice that are useful for long-duration stays. The data from ShadowCam and the unprecedented views into the permanently shadowed regions could also help scientists learn more about how the Moon formed and evolved and about our solar system.

In addition to ShadowCam, NASA is also contributing communications and navigation support to KPLO and science support to the KPLO team via nine NASA-funded scientists. The Republic of Korea (ROK) signed the Artemis Accords last year and continues to collaborate with NASA on lunar exploration efforts.

In ROK, the orbiter is known as “Danuri” after a public naming contest resulted in a name combining the Korean words for “Moon” (dal) and “enjoy” (nuri).

Over the next 4.5 months, KPLO will use a fuel-saving Korean Ballistic Trajectory 62-mile (100 km) lunar polar orbit, where upon arrival, it will then begin operations on a planned 11-month mission.

South Korea's first lunar probe Danuri launched aboard Falcon 9

astronautics 02:08 05 Aug. 2022

The Falcon 9 launch vehicle carrying the Danuri lunar probe, South Korea's first interplanetary spacecraft, lifted off from Cape Canaveral. The probe will operate in lunar polar orbit for at least a year, investigating the composition and structure of the Moon's surface, as well as looking for ice deposits in the Moon's polar craters. The launch  was broadcast on Youtube.

KPLO (Korea Pathfinder Lunar Orbiter) became the first South Korean spacecraft launched beyond Earth orbit. It was created by the Korea Institute of Astronomy and Space Sciences for more than six years, while NASA contributed to the project by supplying one of the scientific instruments, as well as pledging to help maintain communication with the device. The second official name of the probe is "Danuri", which means "enjoy the moon" in Korean. The launch of Danuri will be the first stage of the South Korean lunar program, the second stage of which will start in 2025, when an orbiter and a lander with a lunar rover will be sent to the Moon.

The total mass of the probe is 678 kilograms, it is equipped with two solar arrays, a parabolic antenna, a propulsion system of eight orbital maneuvering and attitude control engines, and five scientific instruments. The LUTI (LUnar Terrain Imager) camera will take detailed images of the Moon's surface, the PolCam camera will conduct polarimetric observations of the Moon in the optical and ultraviolet wavelengths. KMAG magnetometer will study the magnetic field of the Moon and lunar vortices, and the KGRS gamma-ray spectrometer will study the distribution of various chemical elements and water in the surface layer of the Moon. The latest scientific instrument will be NASA's high-sensitivity ShadowCam camera, designed to capture permanently shadowed craters near the Moon's poles. In addition, there is an experiment on board the device DTNPL (Delay-Tolerant Networking experiment) to create a communication channel with the Earth, resistant to delays.

On August 5, 2022 at 02:08 Moscow time, the Falcon 9 Block 5 launch vehicle of the private space company SpaceX launched from the SLC-40 pad at the Space Force Base at Cape Canaveral. This was the sixth flight for this Falcon 9 first stage, and the fourth for both fairing flaps. The first stage successfully boarded the Just Read the Instructions barge nine minutes after launch. In total, this is 127 successful landings of the first stages on the account of SpaceX and 110 missions using the first stages of the Falcon 9 and Falcon Heavy that have already flown.

Forty minutes after launch, the second stage successfully launched the Danuri into Earth orbit, from where the flight to the Moon would begin. The probe is expected to enter lunar orbit by December. After that, it will move to a working polar orbit with an altitude of 100 kilometers, where its scientific program will begin, designed for at least one year.

Earlier, we talked about how South Korea successfully launched its own launch vehicle for the first time.

https://www.esa.int/Science_Exploration/Space_Science/L1_the_first_Lagrangian_Point

Is the white dot by the sun arrow the L1 point?

Seems possible given the distances above and seems to scale to moon orbital distance reasonably well.

From that, the 1.68m km distance is perhaps? not in the direction of the sun so path of Danuri might remain outside the 1.5m km L1 orbit?

Is the L1 point an apogee limit for highly elliptical orbits, but only when apogee is in direct line towards the sun?

Great question, one probably more appropriate on a discussion thread devoted to 3 body dynamics. (In this case the bodies are Sun, Earth, and Danuri.)

Here is a comparison of the webcast telemetry from the TESS and KPLO (Danuri) missions.

I picked TESS because when the tiny 362kg telescope launched over 4 years ago, it was the first SpaceX mission to a lunar orbit, in this case a stable 2:1 resonant orbit. The 678kg Danuri is the second SpaceX lunar mission, using a ballistic transfer orbit.

Both missions used an ASDS landing for the booster, and reached similar velocities at SECO2: 10,412m/s by TESS and 10,517m/s by KPLO in the SpaceX inertial reference system. Orbital velocity is about 400m/s more in both cases.

What is different though, is the acceleration profile during the insertion burns, highlighted in the plot below. KPLO peak acceleration was about 6.9g, and TESS about 6.4g. The heavier KPLO only had to throttle down to limit acceleration for the last 10 seconds, whilst TESS throttled down over the last 30 seconds. Also, TESS was the last mission to use a new Block 4 booster.

I don’t think leg removal is required for booster conversion.

It’s mainly replacing the interstage with a nose cone and relocating the grid fins to the nose cone.

Booster 1052 came back in recently from the #SpaceX KPLO mission without incident, but the cap went up with only 3 (of 4) cables attached. 1 of those dropped unexpectedly and dented the right leg (which caused its removal) & then the cap went back on without any cables. A 1st.
