I read somewhere about about a splashdown in December, so I knew the flight would probably take a little bit. Quote Link to comment Share on other sites More sharing options...

Brotoro Posted November 21, 2022 Share Posted November 21, 2022 The Artemis 1 trajectory makes sense to me now that I understand the Oberth effect and the limited amount of delta-V available in that weenie service module. Quote Link to comment Share on other sites More sharing options...

I won't even complain about the glorious 720p this time, seeing a powered lunar flyby live is so cool. Also, Orion has just entered the far side of the moon - i assume by the time it has to start the burn it will be in direct contact with earth again, right?

If we're real lucky, they might have recorded it for later, but it won't be live. Quote Link to comment Share on other sites More sharing options...

Not sure. You'd have to ask the mission planners about that one, really. I would guess the former. Quote Link to comment Share on other sites More sharing options...

All (practical) lunar orbit insertions for retrograde orbits needs braking burn behind the Moon. With modern tech it is easy but it was real problem during Apollo missions which had to also execute lunar orbit insertions and trans earth injections behind the Moon without communications to Houston.

OMOTENASHI is gone but I haven't heard anything yet about NEAscout. The lastest news I can find is that 20 hours ago the DSN tried to connect first from Canberra and then from Goldstone with NEA Scout, receiving no signal back either time. No DSN antenna is trying to contact it now, perhaps because it's in an unfavourable position They should have more time than OMOTENASHI since there's no burns to make afaik, but at the same time the fact that unlike JAXA they were never able to get any signal from it isn't good Edited November 21, 2022 by Beccab Quote Link to comment Share on other sites More sharing options...

darthgently Posted November 21, 2022 Share Posted November 21, 2022 Was there any proposal to deploy a small lunar NRHO DSN relay sat from Artemis I? Seems like it could have been a great opportunity to make subsequent missions more secure with no loss of signal I would guess that until CAPSTONE proves the orbit viable it would be a big ri$k. Can CAPSTONE do light weight relay work if it achieves NRHO? Quote Link to comment Share on other sites More sharing options...

And that is why Artemis had LOS, correct? I thought, probably incorrectly, that one of the points of Artemis I was to pass through a point where a burn for NRHO could in theory be done, but continue on to distant retrograde for a return. Why did I think that? Neural crosslink with CAPSTONE maybe So, can CAPSTONE do light weight relay work from NRHO if it succeeds? That would be cool Edited November 21, 2022 by darthgently Quote Link to comment Share on other sites More sharing options...
