Might have been a spike upon the abort engine ignition. That seems odd to me as well. The booster lands approximately five miles downrange so that's a pretty vertical re-entry nominally. Maybe the abort kicked the capsule back toward the launch site which made it more vertical? Quote Link to comment Share on other sites More sharing options...

Might have been a spike upon the abort engine ignition. Capsule was at max Q when it escaped at very high g, that thick air would have caused very high deceleration forces once the LES engine cut. So maybe the spike was the decel from escape burn, not normal descent? One thing is certain, while 15g may not seem like much for emergency situations in various craft, I bet people at Shatner's and Funk's age will have second thoughts after this. I wonder how much detailed scrutiny is given typically to LES deployment during max Q with elderly passengers? Quote Link to comment Share on other sites More sharing options...
darthgently Posted September 21, 2022 Share Posted September 21, 2022 (edited) I think the aero forces once the abort engine starts dropping out are what is inducing that wobble. Big forces in thick air at high speed; very quick deceleration Passengers would be redding-out rather than blacking out if they went out at all. Elderly people would be at higher risk for stroke, aneurism maybe with that much neg g Edited September 21, 2022 by darthgently Quote Link to comment Share on other sites More sharing options...
Ultimate Steve Posted September 21, 2022 Share Posted September 21, 2022 Alright that's it I'm going frame by frame and plotting acceleration and velocity based on the official telemetry. There's been too much speculation on this. I might have a little bit of free time tomorrow morning to do it, but in general this week is very busy for me so it will take a while.

I tried, but if I remember right there was something not right about the displayed telemetry or something, I don't remember what exactly.

mikegarrison Posted November 13, 2022 Share Posted November 13, 2022 I assume all those dots are just for motion capture. They probably fed all that video into their dynamic analysis programs in order to capture all the modes. Quote Link to comment Share on other sites More sharing options...

It's kinda cool that the two electronics suppliers in the Portland area are like 15 minutes away from me though Actually, checking a little further, one of them is literally in my neighborhood. I'll be very curious to see what their design is. SpaceX is an obvious choice for one of the landers, so the NT's main competitor will be the Dynetics led team. Pork aside, do y'all think they will actually come up with something reasonably useful and innovative this time (despite the pork and associated setbacks caused by it), or will we get a rehash of the original NT lander, with all of its glaring inefficiencies and anachronisms?

Dynetics, partnering with NG this time, has a much more realistic chance than the "National Team" imo. They actually have a good lander design, and solved the issues they had during HLS phase B Quote Link to comment Share on other sites More sharing options...
