When they start sending people, how long before somebody tries to break the high altitude parachute record? What would be the thermal interface limit?

I'm sure Baumgartner is still sore at the Eustace stunt, he'll be itching to go.

Nice video!

And note the "ring" at the top of the image, how it changes/ablates during the most intense friction.
Looked like heat distortion aggravated by vibration to me...

Look closer at these images - and compare the appearance of top ring. It looks like it gets baked pretty well. (image 1 is at the beginning, image 2 during max friction(?), image 3 after landing)

It's probably not a big deal, and something that can be worked around with better paint/materials - but as it is right now it looks like the New Shepard gets a fresh coat of paint between each flight on several surfaces.

Musk is much more impatient than Bezos. He's fed up with the self-defeating (from economics standpoint) aspects of aerospace and turns it as much on its ear as he can stand. He doesn't care about Bezos "tortoise and hare" approach, because he wants to force industry to change by putting a loaded gun to its head (business dependent on reuse). Bezos "self deals" access by "old space" to same, trading for its experience along the way.

So Bezos US plans, unlike Musk, involve minimax of new/old in splitting apart NS into US/booster elements, refinement, and then on to orbital LV as narrowly as possible. His next goal US wise is a extremely cheap hydrolox US, in that way more like F9US but with better performance and margin. But that is not the end of his ambitions for US.

I don't think you appreciate the dance here that SX, BO, ULA do. Its far more nuanced than you seem to perceive. And your comments don't do it justice.

BO and SX have different sources of income.   Bezos can self fund a go slow approach because of his enormous wealth.  Musk had to hustle for every bit of capital to get SX started and even then SX came very close to failing as a company.  The Analogy is sometimes made that Bezos and Musk are dueling billionaires in the area of Space, Musk wasn't a billionaire when SX was started.  SX is very much dependent on a stream of income coming in by selling it's launch services to paying customers. If BO runs low on funds, Bezos just whips out his checkbook.  Musk is seeking to dominate the space launch market because every order that SX books gets them closer to their goals of manned Mars missions.

Wow, this is the very first time I've ever heard audio on a spaceflight video.

It isn't at all new, though this is certainly the best, what with the actuators, the thing that goes ping and the spooling-down of the turbopump at the end. Lots of semi-pro sounding rocket videos have audio, but there's generally not a lot going on after burnout other than wind, some parachute noises and crunching as they land. This video from BO is in a new class...

The SRB reentry/recovery videos had sound.

Very cool sound:

Listening to that felt like there was a percussion group playing in musical accompaniment.  8)


But regarding this latest video from Blue - what is the GH2 vent, anyway? Gaseous Hydrogen Vent No.2?

From the video, it seems like the camera is sitting somewhere immediately below the ring-fin thing.



If you look just above where the American flag decal is positioned, it seems like the camera was roughly located around that height along the body axis. Just wondering if that thing above the flag decal is the vent.

Is the camera placed in the vent because that's a safer recessed place, protecting it from the slipstream?

Here's a view from above:



Is that slight protuberance at about 7 o'clock where the vent is?

We mods have scissors and we are not afraid to use them. This is not another one of those threads.

Because it is not really a spaceflight.  It spends most of the time in the atmosphere and hence sound is available

It's too bad they couldn't superimpose an altimeter reading in one corner, for the duration of the video. Would be interesting to cross-reference that with what's happening in the video. Maybe even a velocity reading would be interesting too.

It's H2, just Gaseous Hydrogen.

That and sound is transmitted just fine through structure even in a vacuum.

Case in point: all the recent GoPro videos on ISS EVA's.
Plenty of fascinating sound to hear there in the vacuum, just another medium.

Wow, this is the very first time I've ever heard audio on a spaceflight video. It really gives a much more authentic impression of what it would actually be like to be sitting aboard one of these rockets while it flew.

Normally, all these spaceflight videos are silent, and nobody bothers including audio. Many thanks to Blue Origin for finding yet another small way of providing more to us spectators!  :)

It may be that "in space, they can't hear you scream" - but to hear the hums, whirs and clicks of the rocket's machinery while it descended into the atmosphere was so nice. Thanks again for this, and I hope we'll get more such audiovisuals from future rocket flights.

Then you absolutely must play this , and stick around till it re-enters.

Hi-Fi audio definitely required.

Wow, it really does sound like performance art from a percussion group.  8)

Watching the other SRB spinning perfectly in tandem in the vacuum reminded me of that "space baton" scene from 2001: A Space Odyssey.
