Motokid600 Posted July 19, 2018 Share Posted July 19, 2018 So what was the point of firing the LES after booster sep again? Just to use it as a second stage and go higher? Quote Link to comment Share on other sites More sharing options...

After stage sep, there is no reason to fire the LES, ever. I guess the claim is to fire it in a particularly thin atmosphere (100km), but I have trouble imagining that there was any worry it would not work.

Nightside Posted July 19, 2018 Share Posted July 19, 2018 Is New Shepard supposed to be capable of orbit or is it ballistic only? It seems like they've done a lot of testing without ever getting very far. Also, are there regulations for a privately funded, commercial space capsule? If NASA is not paying for it, who would regulate for safety? Quote Link to comment Share on other sites More sharing options...

Expand 1) Suborbital tourism. 2) FAA. https://www.faa.gov/about/office_org/headquarters_offices/ast/human_space_flight_reqs/ 1+2) The FAA mandates that they must do flight testing before human passengers are allowed on board. What they have done so far is nothing compared to the amount of flight testing that a commercial airliner has to undergo before paying passengers are allowed to fly on it.

tater Posted July 19, 2018 Share Posted July 19, 2018 If the flight time was increased by even a minute, that's a 20-30% improvement in the microgravity time for the passengers or experiments. If that matters. Quote Link to comment Share on other sites More sharing options...

Expand I’m wondering if maybe they figure those abort motors have a limited lifespan, “use it or lose it” after n hours/flights/etc. So they run it up to its “expiration” then offer an extra-long, high-G special flight for their more adventurous passengers... for a small premium, of course.

MaverickSawyer Posted July 19, 2018 Share Posted July 19, 2018 I suspect that this test was more for an edge case reentry from significantly higher than normal. I.E., if it survives this, it'll survive any expected reentry. Quote Link to comment Share on other sites More sharing options...
Brotoro Posted July 19, 2018 Share Posted July 19, 2018 I was concerned when I first heard that they were going to do an abort test off of their shiny new (relatively) booster...because it seemed sad to risk damaging the booster. But doing the burn 20 seconds after separation, and (it appeared from what I saw during the flight) aiming the capsule abort motor thrust away from the booster was a good move.

mikegarrison Posted July 19, 2018 Share Posted July 19, 2018 So in the video, the commentary said that the reason for the test was: 1) how well does the LES motor work at that altitude? 2) how well will capsule handle the stress (remember, this is their capsule 2.0)? 3) how will the capsule handle the extra re-entry energy? So it seems as if the answer "all of the above" was in fact correct. Quote Link to comment Share on other sites More sharing options...

Wjolcz Posted July 21, 2018 Share Posted July 21, 2018 Do we know if, apart from the engines, NG is being built/worked on right now? Or are they focusing on testing New Shepard for and after it's finished they will start making NG? Quote Link to comment Share on other sites More sharing options...
