The JPL Horizons system now has data for IM-1, possibly pre-loaded from Intuitive. If it is to be believed, the lander is now 71812 km from the center of the Earth, moving away at 2.8642 km/s.https://ssd.jpl.nasa.gov/horizons/app.html#/*************************************************** Date__(UT)__HR:MN delta deldot*************************************************** 2024-Feb-15 11:35 7.1812412254E+04 2.8642172

I went looking for it:It is in response to a question by Will Robinson-Smith, which is at 20m 5s in the video. "Modified 39A" ... "spent a lot of time qualifying the disconnect" ... "route the lines up through the second stage and through a payload adapter fitting."

Intuitive Machines IM-1 lunar lander
The company had to modify the second stage of the Falcon 9 rocket to add propellants onto the Nova C lander at the launch pad shortly before liftoff. SpaceX and Intuitive Machines completed two tests of this new procedure over the weekend. It's a complex process, and during the countdown, SpaceX actually controls six valves on the lunar lander to ensure the integrity of the fueling process. Despite the tests, a non-nominal methane temperature reading observed late Tuesday night scrubbed the first launch attempt a couple of hours before the planned liftoff early Wednesday.

Falcon 9 launches IM-1 toward the Moon at 1:05am ET this morning
Critical back-to-back Falcon 9 launches in 7.5 hours! Is there anything @SpaceX employees can’t do? I am so proud of the team and the company we have created together. Whether we’re breaking another record or simply working to make SpaceX an awesome place to work—SpaceX rocks!

I don’t see a point in applying an MEK for a 45-minute flight unless they wanted to do some tests after payload separation.
Anyone know the rough parameters of the orbit after TLI burn?
