Anyone else have a problem? Hope this isn't a bad omen!

I'm getting the same error messages for the "track the mission' tab, but other tabs seem to work.

 

[LabRat]

It appears NASA have fixed the problem, I just checked a few mins ago and it is working now!.

Interesting how much Orian is slowing down, (it's now only doing 824mph at the time of typing this), and is slowing all the time and is waiting for the Moon to catch up.

 

[Unclear Engineer]

Yes, the idea is to get Orion into the path of the Moon at a slow enough speed and at the right time so that the Moon's gravity captures it into an orbit around the Moon. If it is moving too fast, it just would swing by the Moon and end up in an altered orbit around Earth. (Or, if going fast enough, it would get away from Earth, too, and end up in orbit around the sun.)

Three-body gravitational analyses are complicated. It still amazes me that we can do them so precisely to get things like the DART vehicle to hit something as small as Dimorphos dead center at exactly the right point in its orbit around Didymos.

Have a look at The FREE NASA tool GMAT.

Thank you LabRat!

Your welcome Engineer.
Orion is now down to 365mph (at time of writing this).

View from the moon. (see its even slowed more just a few minutes later).

 

[Unclear Engineer]

It would be interesting to see the parameter of Orion's velocity with respect to the Moon, as well as with respect to Earth.

 

[LabRat]

Orion has now slowed to 147mph. Snoopy might have to get out and push if the moon doesn't catch up soon

 

[Unclear Engineer]

I am wondering how this velocity parameter relates to the various coordinate sets. Is it total velocity with respect to Earth, or just radial velocity with respect to Earth (which would be close to zero for an object like the moon in a near circular orbit)?

And, with respect to the Moon, I wonder what Orion's velocity would look like. How fast is the distance between the Moon and Orion closing? Since the goal is to go into orbit around the Moon, at some point it makes sense to switch to that frame of reference.
