Title: New sub-orbital booster engine -- reuseable --
Post by Oldfeller on 11/24/15 at 08:51:02

Look at the YouTube and you tell me what is different about this small, highly efficent booster engine, that punches straight up plenty high enough to let the instrument package's sub motor carry it the rest of the way on up to high orbit, and then comes straight back down again to the same landing pad for refueling and re-use.

This is what has replaced the USA's NASA Space Program (the unclassified portion of it, anyway).

Well I am not a Rocket Scientist....but that looks pretty cool. Looks like the "Big Single" of the rocket world!

It does appear to be a lot smaller than the NASA rockets I have seen launched, and I imagine the payload is dramatically lower as well.

I sure hope they either put a bigger chute on the capsule when they actually have passengers - or give them some really soft cushions to sit on, as they landing looked to be pretty hard!

space tourism, designed to go up 60 miles only.
space station is 205 to 270 miles.
not that it would take much more effort to get there.

Engine gets a soft landing... Passengers,?..
We already have their money.. ;D...

pretty sure that poof you see at the end is a retro rocket firing before the capsule lands.
might be a takata air bag :-?

Seen the video, seen the CGI in the middle of the video..... wondering how much of the video is real, and how much is CGI......

Fair question -- here is the raw news coverage to listen to and watch.

Elon Musk's Space-X has been trying it with their Falcon 9 boosters, landing on a floating platform. So far, close but they are still crashing. But the Falcon is a lot bigger rocket than Jeff Bezos' thing.

It's pretty easy to see what is required: 1., a lot more fuel and oxidizer than is needed to go up and then flame out, 2., solid gyros and nav software to find home and arrest the descent right on time, and 3., very fine responsive vectored thrust responding to the gyro inputs.

Bezos pulled it off first, but there were some pretty wild excursions trying to stabilize the rig. Before these systems become dependable they are going to need a lot more precise control so they come down on a rail and land like a feather. But I guess it is worth doing from an economic perspective. Rocket engines and booster sections are pricey things to throw away after one use.
