Looks like the lunar orbits are getting crowded too
Jeff Foust said:
Interesting fact from today's Summit for Space Sustainability meeting: Korea's KPLO lunar orbiter has had to perform 3 collision avoidance maneuvers in 18 months. One to avoid LRO, one for Chandrayaan-2, and one for SLIM before its landing. #swfsummit24.

I think John Glenn might have something to add to this conversation.
Glenn's previous mission before his final one being at age 40. So, if Glenn is an apt comparison, that would suggest, at his age, maybe Wilmore will get one more mission.

I doubt that the prospect of flying on future missions is what's keeping his mouth shut, is my point.

Mission failure or at least only partial success.

Elon Musk said:
Upper stage restart to raise perigee resulted in an engine RUD for reasons currently unknown. Team is reviewing data tonight to understand root cause.

Starlink satellites were deployed, but the perigee may be too low for them to raise orbit. Will know more in a few hours.

That's a rare one. Vacuum Merlin is so reliable that once in orbit I tend to just assume the job is now done.
Indeed. Traditionally, something like this might halt flights for some time. I hope the upper-stage build records and flight telemetry provide solid clues to the failure.

And it's bad news that there may be a lot of extra orbital junk around, but the good news is that the perigee (NOT pedigree, thank you very much, auto-correct) of all shrapnel should be low enough to ensure re-entry fairly soon.

Elon: "We’re updating satellite software to run the ion thrusters at their equivalent of warp 9.

Unlike a Star Trek episode, this will probably not work, but it’s worth a shot.

The satellite thrusters need to raise orbit faster than atmospheric drag pulls them down or they burn up."

I watched the launch live, and I also noticed the abundance of 'ice' on the vacuum Merlin. Usually, you just get a few "space mice" chunks rattling around, but this launch it was like a small leak was feeding a whole area. Not being a SpaceX engineer, I don't know the tubing-runs of the Merlins. However, the anomalous leakage and the unusual RUD could seem to be related...
