I am starting a new thread for this mission which should fly this year.
Phil
Any rough idea about the date (month)?
Thorsten
https://twitter.com/Columbia1938/status/1494818072376614927
This tweet suggests a summer 2022 launch date for IM-1, about a 3 or 4 month delay. I can't vouch for the veracity of the tweet, but other commentators say near the end of the year, so this is more encouraging.
Phil
As of 3/25/2022, https://spaceflightnow.com/launch-schedule/ says 3Q 2022 and https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=IM-1-NOVA says "mid to late 2022".
IM-1 likely near the end of the year now (Q4 according to a chart at the Lunar Surface Science Workshop now underway).
News from that LSSW meeting, only 30 minutes old as I type: Lunar Flashlight, a cubesat designed to survey volatiles in shadows at the south pole, was to fly on Artemis-1 but is now - this is the news - manifested as a secondary payload on the IM-1 Falcon 9. Stated by Barbara Cohen at the meeting.
Phil
Set to launch on 22 December (this year...) according to NASA:
https://www.nasa.gov/launchschedule/
Phil
https://www.hou.usra.edu/meetings/leag2022/pdf/5027.pdf
This link goes to an abstract for the upcoming LEAG annual meeting. The abstract is a summary of the CLPS program so far.
For me the most intriguing thing is a brief reference to the Intuitive Machines IM-1 mission (launch late 2022) which says that it will land in Mare Crisium.
The last statement from Intuitive Machines themselves is that the landing site is on the Aristarchus Plateau. There was an LPSC abstract on mapping the landing site. Their orbital debris (ODAR) report said they would land between Mare Serenitatis and Mare Crisium. I took that to be a simple mixup between east and west longitudes with the real target still at Aristarchus. But now this puzzling statement!
So, is the landing site the Aristarchus Plateau, or Mare Serenitatis (which was stated by Intuitive at LEAG a couple of years ago) or somewhere between Serenitatis and Crisium, or in Crisium itself? Does 'between Serenitatis and Crisium' mean somewhere in the middle, or does it mean that the choice is between Serenitatis and Crisium?
It's like trying to follow Chang'e 4. Maybe we will get clarification at the meeting. I will report on it.
Phil
Perhaps a bit O/T but from that paper Phil posted we get this:
TO CP12 (PRISM1B): Two PRISM payload suites
are included in the delivery to Schrödinger Basin on the
lunar farside in 2025. Instruments include long-lived
seismometers [8], a heat flow drill with a
magnetotelluric sounder investigating the subsurface.
TO CS3 (Science): This science delivery is
planning to land at the farside mid-latitudes in 2025.
Low-frequency radio astronomy with standalone
operations through the night will be performed
Whats the plan for data relay for these farside missions?
another Phil
Several possibilities are being discussed. Commercial relay services are being considered separate from CLPS, and also relay services provided by the CLPS mission, by release of a relay satellite into orbit before landing or as a rideshare. Relay via the Gateway is also possible.
Phil

Phil
Here is the announcement of the Schrodinger mission:
https://www.draper.com/press-release/nasa-awards-draper-73-million-deliver-suite-payloads-moon-2025
It says the mission will deploy two small relay satellites in lunar orbit.
Phil
And back to IM-1, here is Jeff Foust retweeting (from Thomas Zurbuchen) its expected launch date as January 2023:
https://twitter.com/jeff_foust/status/1550220907607629831
so upcoming lunar launches (no earlier than dates) as currently stated:
Artemis 1 end of August/early September carrying several lunar and other cubesats*
ispace Hakuto-R to Atlas crater c. November 2022
Astrobotic PM-1 to Lacus Mortis c. December 2022 (they are still giving this likely date, others might expect a slip)
Intuitive Machines IM-1 to Aristarchus Plateau (probably, despite some confusion in various statements) c. January 2023
* I assume talk of Artemis 1 and future Artemis missions will be outside our scope here on UMSF, but the small cubesat missions should be OK. One will attempt a landing, the Japanese OMOTENASHI mission. It is only a tech demo but will still be interesting to watch.
Phil
https://twitter.com/SpcPlcyOnline/status/1560343096533176324
A tweet from Marcia Smith at the Planetary Science Division Town Hall, with a graphic of CLPS missions. Once again IM-1 is said to be landing at Mare Crisium. Not a squeak out of Intuitive, though - and I have asked them via their somewhat ineffective website. Come on, IM, you can do better than this.
Phil
OT but given Masten's recent bankruptcy I'm surprised to see them still listed.
Yes, surprising. Strictly speaking the mission is not cancelled but its chance of proceeding is very small, as far as I can see.
Phil
Ghe Intuitive Machines website:
https://www.intuitivemachines.com/
has just undergone a redesign, making it much more useful in advance of its first mission. There is a list of payloads:
https://www.intuitivemachines.com/_files/ugd/7c27f7_149bfeccc38c4e409dd6634a345969ab.pdf
and clearly it is being set up to support the upcoming flight. No word still on landing sites, but I am thinking they are probably keeping several in play until the launch, so a delay of a day or two in launch allows them to shift to the west to maintain an early morning landing. If that is the case it makes sense to start in the west (Crisium) so later landings can go to Serenitatis or Aristarchus Plateau as needed. Basically the same strategy as the first Apollo landings used.
Phil
It's a very important meal. You can't just grab a sandwich from Pret.
Phil
(Oh, OK, I'll fix it)
Aha - now we have real news.
https://arstechnica.com/science/2022/09/in-a-bid-to-expand-its-moon-business-intuitive-machines-will-go-public/
Apart from the funding aspect of that article, at the end there is a statement that NASA has requested a south polar landing instead of a near-equatorial one. Re-planning the trajectory and so on has caused a delay to March 2023 for launch.
Elsewhere there was a comment that a 4th IM mission will be purely commercial, not a CLPS mission. 'Commercial' in this sense should be taken to include the possibility of a flight on behalf of another nation's space agency as well as purely business-oriented partners. (No, I don't have any special knowledge of the situation, but I am so used to seeing comments that no commercial clients have deep enough pockets that I wanted to point out that possibility. UAE is already flying a rover on a Japanese mission and looking at a similar arrangement with China, and Canada wants to fly a lunar mission, so there are candidates already known and could easily be more).
Phil
Intuitive update. At the Lunar Surface Science Workshop yesterday, Jack Burns gave a presentation on ROLSES, an instrument on IM-1. It identified the landing site quite precisely, just east of the very degraded crater Malapert A. The coordinates are 80.31 S, 1.24 E. Flight now expected in the later part of the 3rd quarter of this year (c. September).
Phil
This is the landing site for IM-1 as currently understood. It looks like the lander has been boxed up for transport to KSC.
Phil
Mission slipped to mid-January: https://spaceflightnow.com/2023/10/27/intuitive-machines-targets-launch-to-the-moon-in-mid-january/
If there are no more delays (a big IF, certainly) Astrobotic's lander will launch before IM-1, currently aiming for 24 December. If Intuitive Machines launches on 12 January the landings would actually happen close together, round about the 19th of January, and SLIM is also set to land at the same time.
It is possible that we will see three landing attempts in a single week. If we assume every landing happens about 2 days after sunrise (so descent imaging is not too complicated by shadows) they would occur in the order of increasing west longitude, i.e. SLIM, then Intuitive, then Astrobotic. Dates might be roughly January 18, 20 and 23 (Thursday, Saturday, Tuesday).
Astrobotic seems to be Jan 25.
https://twitter.com/SpaceflightNow/status/1729942846130606349
Thorsten
Yes, they are landing 4 days after sunrise and aiming for a 10 day mission, so my working assumption of landing 2 days after sunrise put me 2 days out.
Phil
It will be interesting to see if the other dates hold.
If so, there would still be three landings within one week (seven days)!
Thorsten
The landings look different now! SLIM in January still, but with Astrobotic and Intuitive both delayed a month, they could both land in the same week, around 20-23 February.
Phil
The Intuitive Machines IM-1 lander has been named Odysseus.

Final preparations underway for launch of first Intuitive Machines lunar lander (by Jeff Foust)
https://spacenews.com/final-preparations-underway-for-launch-of-first-intuitive-machines-lunar-lander/
There is not yet an official specific date for the launch, only "a three-day launch period for the mission in mid-February".
It might be NET Feb14.
Landing attempt on the Moon, if launched this month, will be Feb22.
Thorsten
Does this lander contain the drill as originally proposed?
I do not see this instrument listed in recent posts.
The Trident drill is on IM-2 later in the year.
Phil
Btw, the launch will be Wednesday Feb 14, at 05:57 UTC.
For the Americans, this is the night Tue to Wed, 12:57 AM EST.
In less than 1½ days!
Thorsten
Delayed now, to the 15th.
Phil
Yes, and 8 minutes later.
Feb 15 at 06:05 UTC now.
Thorsten
Frustrating to me... Intuitive Machines has not released a definitive map of their landing site (welcome to the world of commercial lunar exploration... Astrobotic didn't either). This screenshot from Quickmap shows three locations defined by coordinates, from an LSSW presentation, a PSAC presentation and the LROC website, and also a box showing the location of an LRO image at:
https://www.lroc.asu.edu/posts/1321
Remember that the image background on Quickmap can contain registration errors. But that's not enough to account for all this variation. The LRO site is much smoother than the points further south.
Phil
Launch has occurred and IM-1 is currently in a parking orbit before TLI burn.
Edit: Separation from Falcon 9. Gorgeous views.
Is there any information if they have successfully established radio contact with the lander and that everything is nominal?
Thorsten
At the end of the NASA stream, yes there was a callout of data packets coming in. Some clapping too.
"IM-1 mission Nova-C class lunar lander has launched on SpaceX’s Falcon 9 rocket and successfully commissioned in space by establishing a stable attitude, solar charging, and radio communications contact with the Company’s mission operations center in Houston."

Is the landing time already publicly known?
The date is in one week, Feb22.
But what hour?
Thorsten
I have also been wondering that... I want to put an alert in my diary.
As has already been noted, this private mission is less forthcoming than NASA or some other governmental missions.
SpaceflightNow is stating the landing will be late on Feb. 22.... hardly very precise, but at least provides some definition around the landing time....
" The mission, dubbed IM-1, lifted off at 1:05 a.m. EST (0605 UTC) at Launch Complex 39A. It kicks off a roughly eight-day journey to the Moon, culminating in a landing late in the day on Feb. 22."
https://spaceflightnow.com/2024/02/13/live-coverage-spacex-intuitive-machines-to-launch-falcon-9-rocket-on-moon-bound-mission/
The critical first engine firing (commissioning burn) is coming up in an hour so at about midnight Feb. 15 UTC. (19:00 ET).
"Once the lander completes the engine commissioning, there are up to three trajectory correction maneuvers that are short firings of just a second or two. That’s followed by the lunar orbit insertion (LOI) burn, which lasts about seven minutes.
The lander will then fly in a circular, low lunar orbit (LLO) of 100 kilometers above the Moon’s surface for about 24 hours, which is followed by the descent orbit insertion (DOI), which comes about 75 minutes ahead of landing. "
The LROC DTM and rectified orthophotos of the Malapert A landing site are available from https://wms.lroc.asu.edu/lroc/view_rdr/NAC_DTM_MALAPERTA01.
Intuitive Machines just issued a 4-page PDF file with a Vehicle Health Update.
Link: https://www.intuitivemachines.com/_files/ugd/7c27f7_6f08ded687bb4950bff004e566d8e2f0.pdf
They are preparing for the engine commissioning manoeuvre.

Update on IM-1
The engine commissioning burn due last night was delayed.
It seems it has not yet happened.
https://www.intuitivemachines.com/_files/ugd/7c27f7_0c7c9c1dddb0422694b16e6ec4c28242.pdf
The IM-1 mission Nova-C class lunar lander continues to be in excellent health, in a stable
orientation and remains on schedule for a lunar landing opportunity on the afternoon of
February 22. The original mission structure allocated a Commission Maneuver (CM) and three
trajectory correction maneuvers to position for Lunar Orbit Insertion. This approach provided
flexibility in the mission’s engine burn schedule to allow for learning as we operate the lander
in the vacuum of space. Adjusting for this learning process is why the team chose to delay the
burn on February 15.
Communication delays and outages are expected when executing lunar missions, which we
accounted for in our mission planning. While preparing for the CM burn last night, flight controllers
experienced intermittent uplink and downlink data communications between Nova-C and the
ground stations, potentially impacting our ability to collect the critical information required to
support the CM burn and follow-on performance analysis.
As we prepared for the first-ever in-space ignition of a liquid methane and liquid oxygen engine,
we reviewed our Earth-based test data against the data we’ve accumulated in space. The inspace performance demonstrated that it takes longer to chill the liquid oxygen feed line than
the Earth-based testing. After understanding the in-space liquid oxygen feedline requirements,
we adjusted and uploaded the CM burn preparation timeline and increased the onboard event
sequence timer.
Again, the IM-1 mission Nova-C class lunar lander is in excellent health, and we expect to continue
to provide mission updates at least once a day.
https://twitter.com/Int_Machines/status/1758677812217545020
That burn has been done successfully now.
Phil

"...lunar landing opportunity on the afternoon of February 22."
I suppose that this is US time, so for Europe it should be in the (late) evening.
With the Moon well over the horizon.
I love to see the Moon during a Lunar landing,
just the imagination that this happens AT THIS MOMENT RIGHT THERE!
Thorsten
First pics -- wow! (from their https://www.intuitivemachines.com/im-1)
As Phil noted, the burn went well and the "engine firing included a full thrust mainstage engine burn and throttle down-profile necessary to land on the Moon" (see entry on this page https://www.intuitivemachines.com/im-1 .
The third image from Hungry4info's post shows most of Australia. I wonder what the Earth-Moon trajectory looks like in 3D...
Fernando
https://www.youtube.com/watch?v=CyG5WtD8Gjk
If I'm thinking of the object you are, it's the upper stage of the rocket that launched it.
Yes, in the first image a few minutes after separation, it's very obvious!
https://www.intuitivemachines.com/_files/ugd/7c27f7_ef85f351ed5f44f19e312b145fb671b8.pdf
Lunar Landing is planned for Thursday Feb 22 at 22:49 UTC.
Lunar Orbit Insertion one day before. Hour I don't know.
Thorsten
All seems to continue to go well for the IM-1 mission. The 1st and 2nd TCMs were so successful that the 3rd TCM is not needed and was cancelled.
See https://www.intuitivemachines.com/im-1
Today is Lunar Orbit Insertion, at about 100km altitude. Odysseus is supposed to make about 12 2-hour orbits before attempting landing.
From this orbit it will descend to 10km, which takes about an hour, followed by powered descent. So I'm guessing that LOI will be around 21:00 UTC today.
The details above, along with a wealth of other information, are in the PRESS KIT (https://www.intuitivemachines.com/im-1?lightbox=dataItem-ls22wsqq)
Fernando
PS - I hope the sky is clear!
According to Jonathan McDowell, the first perilune is today at 14:40 UTC.
https://twitter.com/planet4589/status/1760180109925929154
"IM-1 is now inside the lunar gravitational sphere of influence and heading towards a 100 km perilune at 1440 UTC"
"I estimate the lunar orbit insertion burn needs a delta-V of 600 m/s"
I suppose that LOI will be done at perilune (?)
Thorsten
LOI successful!
https://twitter.com/Int_Machines/status/1760323743270756500
Thorsten
So, Jonathan McDowell was right and I'm very happy that another difficult step is behind Odysseus!
Now, to keep the landing time, either more orbits are needed or the orbital period is much longer than the 2 hours I understood from the Press kit.Given that the 92 km circular orbit is a bit lower than the one originally mentioned, perhaps the former?
Fernando

Apparently the lander's laser altimeter isn't working. They're involving some other NASA assets (I didn't quite follow how exactly) to compensate.
https://www.nasa.gov/centers-and-facilities/langley/nasas-laser-navigation-tech-enables-commercial-lunar-exploration/ (apparently not a demo now!) They really want to land now rather than troubleshoot.
Just minutes from PDI. About 10km altirude and 1100km downrange...
PDI has started and is going well. NDL is working!
(Thanks, Explorer1, for helping clarify the situation)
PDI ended, now in terminal descent.. 2 mins to touchdown
It's been on the ground for a few minutes now but no contact.
On the lunar surface!
They are getting faint signal.
Broadcast has ended. Last coments pointed to a successful landing, so congratulations to all the teams.
Now, lets wait for those "3rd person view" images!
Per multiple fairly reliable interested social media accounts (including AMSAT -DL who are actively tracking the signal themselves) and following updates over on NASASpaceflight : A weak signal has been received from the lander on the surface. There was an 8 degree roll excursion towards the end of the EDL. Palms up I am only guessing, but wonder if the roll in question was one to get the lander in the right orientation for landing - in which case the antenna's pointing might be off, perhaps accounting for the weak signal (this is Scott Manley's suggestion).
Not perfect perhaps, but promising.
https://eyes.nasa.gov/dsn/dsn.html currently has the big Madrid antenna engaged with "LND1" = "Lunar Node 1" at the moon, which https://www.nasa.gov/centers-and-facilities/marshall/nasa-to-demonstrate-autonomous-navigation-system-on-moon/. (Not showing any signal right now, for the avoidance of doubt.)
There's also a https://status.ghy6.goonhilly.org/ for the GHY-6/Merlin antenna at Goonhilly (Cornwall, UK) which is involved (possibly the primary antenna?) for the IM-1 mission, and was mentioned on the webcast.
Update!
I am really looking forward to these images! And confirmation of the exact landing point.
Phil
from reading twittr this morning, some are having some doubts over how successfuly IM-1 landed.
The antenna simply might point into the wrong direction.
https://twitter.com/coastal8049/status/1760926397168546247
Thorsten
Bonjour,
Really !!!
https://arstechnica.com/space/2024/02/a-little-us-company-makes-history-by-landing-on-the-moon-but-questions-remain/
Can China help with the Queqiao-1 or with the Queqiao-2 satellites? If Antenna direction is the problem.
Politics aside, they must be very incompatible systems. There's no equivalent to MRO for relaying at the moon (LRO can only make photos).
And Queqiao-1 is on L2, behind the Moon.
The antenna, if it points wrong, might be a few 10s degrees off, not 180°.
Not to mention that Queqiao-1 would be below the horizon for IM-1.
Thorsten
Appears a little more hopeful today in this latest tweet:
"Lunar Surface Day One Update (23FEB2024 0818 CST)
Odysseus is alive and well. Flight controllers are communicating and commanding the vehicle to download science data. The lander has good telemetry and solar charging.
We continue to learn more about the vehicle’s specific information (Lat/Lon), overall health, and attitude (orientation). Intuitive Machines CEO Steve Altemus will participate in a press conference later today to discuss this historic moment. Press conference information will be coordinated with NASA and published shortly."
https://x.com/Int_Machines/status/1761032731729739804?s=20
Though no photos yet ...
They for sure will keep the photos for the press conference.
https://www.nasa.gov/news-release/nasa-intuitive-machines-to-discuss-historic-moon-mission-today/, said press conference is scheduled for 2200 UTC (5pm EST).
And even if it were, it would be a "moving target".
If finding the Earth alrady is difficult, what then about a fast moving satellite?
Btw, Press Conference at 22:00 UTC.
And the EagleCam is alive, but it was deliberately NOT (yet) deployed.
Thorsten
DSN Now shows Lunar Node 1 from Madrid (data rate of 0 however).
And the https://status.ghy6.goonhilly.org/ currently shows its S-band receiver "IN LOCK" to IM1, which I didn't catch it doing yesterday.
(Earlier today it was talking to https://en.wikipedia.org/wiki/Aditya-L1)
Looks like landing sideways is a trend for landers in 2024...good thing there's solar panels on multiple sides!
How do they know it's a rock keeping it propped up, with no photos?
I think the story ?Steve told was that there was 2mph residual lateral velocity (and 6mph downward), and they think it tripped on a rock.
The previous story that it was upright was based on seeing tank telemetry saying gravity was in the X direction; but that telemetry has been determined to be stale; now the tank is telling them gravity is on the Z axis. (E&OE)
They've only showed one new pic, from 10km up. Still trying to get surface pics down.
Hoping to get an image from LROC this weekend.
I think they just said the notion of using the NASA lidar to help landing was somewhat anticipated, not completely improvised.
Vertical landing speed was 6 times planned, and the 0 lateral planned speed ended up being 2mph, hence it fell over.
OMG they forgot to remove the manual "before flight" safeties on the lasers.
Oof, the reason the laser rangefinder didn't work was that a safety switch (it's not eye-safe) wasn't disabled, and couldn't be disabled remotely by their software. They first discovered this while in lunar orbit (which was more elliptical than they'd planned; not sure if they'd have tried it if the orbit was nominal. [edit:] Irene Klotz asked: and no, they wouldn't have otherwise tried it before powered descent; would probably not have found out until 5 min before landing 😬)
[edit] Clarified later that it was a physical switch with no software override, not just that the software they had didn't know how to do it.
It was interesting to hear that both the IM-1 and the SLIM lander currently operating on the Moon working but are lying on their sides. I guess that the way to mitigate against the same problem happening in future landers is to fit a small solar panel on every surface of a lander to provide solar power no matter what the orientation is.
Other bits and pieces I noted from the presser:
A very informative (and dramatic!) press conference, all without any photos. Now we wait for images.
Hopefully the Nova-C, with its drill, goes fine, so it doesn't just drill vacuum...
"Looks like landing sideways is a trend for landers in 2024...good thing there's solar panels on multiple sides! How do they know it's a rock keeping it propped up, with no photos? "
The legs stick out at the bottom so if it was just resting on a flat surface and the legs were intact the body would be tilted down, with its intended top on the ground. But they have a measure of the gravity vector and also information on the position of the residual fuel in the tanks, which apparently tells them the body is horizontal. The model they showed had its head up on a rock, but he also said it might be that the legs are in a depression. Either could give a horizontal body. He said something about a leg hitting the rock and toppling over. When i think about the geometry of that it seems to work better if the legs hit the side of a crater and it falls over on the rim with the legs still in the crater. But all speculation until we get some pics.
Phil
Interesting press conference, though I heard there was a 2m/s lateral velocity that was meant to be nulled, I didn't pick up an explanation as to why it wasn't, did anyone?
It would seem that this is even more important if you design a lander with the apparent C of G higher than the landing leg attachments (unlike Surveyor with it's wide stance)
With these new AI video tools, it should be easy to make a simulated blooper reel of failed planetary landings. A lunar lander tipping over; Venera trying to probe the surface right where its lens cap popped off; a Soviet Mars lander touching down perfectly, then being covered by its parachute; the Galileo probe missing the clouds that cover 99% of Jupiter, the Genesis return capsule smacking into the desert. We've definitely established that Murphy's Law applies everywhere in the universe.
They should design these things with landing legs like a tetrahedron so that it doesn't matter what orientation the craft ultimately ends up at after it lands. All instrumentation would be on a gimbal in the center that keeps itself oriented.
"a Soviet Mars lander touching down perfectly, then being covered by its parachute;"
If the HiRISE identification is correct, that parachute hypothesis is not true.

The astronomy instrument has some news and a thumbnail image from the cruise.
Phil
"Prior to landing, we believe one or both of our instruments may have also taken an image of the Moon"
The Moon image they refer to is "prior to landing," but given the orientation, I wonder if they may get a look at the horizon.
"Images from NASA’s Lunar Reconnaissance Orbiter Camera team confirmed Odysseus completed its landing at 80.13°S and 1.44°E at a 2579 m elevation."
https://7c27f7d6-4a0b-4269-aee9-80e85c3db26a.usrfiles.com/ugd/7c27f7_357496b3ba404948ba24ad63081b5d23.pdf
It looks like it may have landed on the edge of a very small crater? The last 2 images from the above pdf I presume are from LRO. Also, the comm window is limited; perhaps only 24 more hours left before contact is lost. From the press conference, it would be considered fortunate for IM1 to survive the lunar night.
(that rather opaque PDF URL being linked from https://www.intuitivemachines.com/im-1; as well as the LROC image, it includes a rather washed-out image from the surface, and another from approach)
https://www.lroc.asu.edu/posts/1360, confirming that's the source of the orbit image, and with blink comparison etc.
Includes "Odysseus came to rest at https://quickmap.lroc.asu.edu/projections?extent=1.0337246,-80.1753373,1.8343734,-80.0795866&id=lroc&showGraticule=true&showTerrain=true&queryOpts=N4XyA&trailType=0&layers=NrBsFYBoAZIRnpEBmZcAsjYIHYFcAbAyAbwF8BdC0yioA&proj=27&time=2024-02-24T13:57:56.389Z, 2579 m elevation, within a degraded one-kilometer diameter crater where the local terrain is sloped at a sporty 12°."
(I've been watching the https://status.ghy6.goonhilly.org/ on and off. When the S-band status suggests it's transmitting to IM-1, the S-band "downlink receiver" status has been sometimes "in lock" but often not, whereas when the antenna's talking to Aditya-L1 it seems steadily "in lock". Dunno whether much can be read into that, such as whether they got IM-1 out of the cycling-between-antennas-etc mode. I guess AMSAT-DL might have been paying closer attention, but I don't have easy access to Twitter/X to check what they might have said.)
The LROC blink image also shows a new bright patch next to the lander- arrowed here. Could that indicate a bounce?
Could be, John.
Here is the location of the site in an image I posted earlier, showing different targets mentioned before landing.

Great observation. I hadn't noticed until you pointed it out.

ILO has images on the ground, hi-res apparently, and will be shared soon.

FWIW, DSS-56 Madrid is receiving data at 50 kbps from Lunar Node 1 right now.
Various of the outlets reporting on IM's prognosis of going dark today suggest EagleCam won't get a chance to deploy (dunno if based on an actual source).
E.g., https://spacenews.com/intuitive-machines-expects-early-end-to-im-1-lunar-lander-mission/, which links to https://news.erau.edu/headlines/eaglecam-updates-embry-riddle-device-lands-on-moon (last updated Sunday), which has some details of how it will/would deploy:
Update from https://www.intuitivemachines.com/im-1 dated <2h ago:
https://arstechnica.com/space/2024/02/it-turns-out-that-odysseus-landed-on-the-moon-without-any-altimetry-data/ has some interesting items. Apparently more images will be released tomorrow.
As for whether this was a success -- I'm reminded of one of my favorite quotes about the Scott expedition:
The article mentions a press conference tomorrow. https://investors.intuitivemachines.com/news-releases/news-release-details/nasa-intuitive-machines-discuss-moon-mission-science-successes confirms that will be at 2pm ET (19:00 UTC).
https://www.intuitivemachines.com/im-1 from a little over four hours ago. Not much info beyond "Odysseus continues to generate solar power on the Moon" and implication it was still talking.
Yesterday I set up logging for GHY-6 (aka 'DSS-59', apparently) https://status.ghy6.goonhilly.org/ (should have thought of it earlier). Haven't fully digested logs yet, but so far I can see that in last night's IM-1 session, GHY-6 was transmitting on S-band between 0300 and 0710 GMT (possibly not continuously, haven't checked), and at no point did the GHY-6's S-band receiver show as being 'in lock'.
(Yesterday's Eric Berger article talked about them using IM-1's 'powerful Quasonix transmitter' for the first time; dunno if/how that would affect the reported status.)
Wow, now that's a broken leg!
Eaglecam was ejected, but no images yet....
Bits and pieces I took away from the press conference not already mentioned:
Three new images were shown during the press conference.
The two that Huguet already posted are now up in https://www.intuitivemachines.com/_files/ugd/7c27f7_90794d5877434b46a9ba1dffea3307aa.pdf.
Here's my screencap of the third (which I think is just the un-re-projected version of one of the others, but additionally shows the horizon, I think).
It's quite difficult to undistort the fisheye image but think I see damage on at least three landing gear assemblies. "A" .. maybe OK; "B" .. completely detached; "C" .. just torn thermal blanket?; "D" .. if this is a pad, that strut is badly out of place. I need to go back to the Press Kit to determine if the "tilted image" (also released today) is viewing the same panel as this one is -- if so, "A" is certainly damaged and "C" is enough off the regolith for the pad to throw a shadow. Also, if "B" is completely detached, it came from the far side of IM-1, implying that the direction of motion is upward in the photo. A lot of guesses, I know ..
.. a comparison of in-flight and post-landing structure.
Here is an updated moon map showing landings and impacts. I am classifying IM-1, SLIM and Luna 23 as successful landings (as I would Mars 3 and Beagle 2, based on what we know now). on the basis that they were able to operate to some degree after reaching the surface. If you are in bits on the surface it was not a successful landing. If you can transmit anything or start to deploy solar panels (Beagle 2) it was a successful landing. The question of whether or not it was a successful mission is a different matter and not one I am concerned with here. I am of course clarifying this because of the endless chatter about this topic in other places.

A couple images from ILOA. in one you can see the surface and a detached leg on it. I also share a photo I found (can't recall where) showing the damaged legs from a before/after perspective. It helps make sense of the leg situation at landing.
"It's quite difficult to undistort the fisheye image but..."
Paint Shop Pro and Photoshop both have functions that can normalize a fisheye lens.
I've not tried it yet, but I'll report back.
Simeon Schmauß already has done this and produced astounding results!

Attached is a section of the image, looking toward the crater, with bits of regolith sent flying by the engine plume.
If you do unspeakable enhancement of the IOLA image you can see a landing pad and the suggestion of a strut a little distance from IM-1 ..
Here is my take in making a panorama out of the fisheye view at contact (click on the picture to browse the 360° panorama):

It gives pretty nice results with the other ILO-X WFOV pictures:

"Lunar Surface Day Seven Update" from https://www.intuitivemachines.com/im-1 (dated 0920 CST = 1520 UTC):
One more image posted at the https://www.intuitivemachines.com/im-1, including an (overexposed) crescent Earth. (https://static.wixstatic.com/media/7c27f7_9c4b6f176abc4642a21aecda5a3e9624~mv2.png)
(Also an implication that it has finally gone dark.)
I have identified a few of the features in the last Intuitive Machines last image release, on an LRO image of the IM-1 Odysseus landing site.[attachment=54697:IM_1_features_1.jpg]
Zoom in on the LRO image to see the small identified feature numbers.
https://investors.intuitivemachines.com/news-releases/news-release-details/intuitive-machines-historic-im-1-mission-success-american (dated yesterday EST); not much new beyond confirming IM-1 "entered standby mode on February 29, 2024".
(But there's another GHY-6 pass scheduled for tonight. Odd.)
The Sun has risen at the IM-1 site. Maybe there will be an attempt to revive it.
Meanwhile, this is a very tentative experimental map of its landing site. Unfortunately, none of the descent images we have looked in the right direction to view the surface on which it landed, the the base is a grossly over-enlarged LRO image.
This is subject to change as we learn more.

There's an update dated March 23rd on https://www.intuitivemachines.com/im-1. They listened, but didn't hear anything.
