Intuitive Machines just issued a 4-page PDF file with a Vehicle Health Update.

Update on IM-1
The engine commissioning burn due last night was delayed. It seems it has not yet happened. IM-1 update Feb 16 2024 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. |

That burn has been done successfully now. Phil -------------------- ... because the Solar System ain't gonna map itself.

"...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 |

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 |

First pics -- wow! (from their website) What is the very small, roundish bright thing (floating against the black background) visible in three of the images? |

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!
First trajectory correction manouvre was nominal (and they are promising daily updates). |

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?ligh...taItem-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 (?)
