According to the book on Apollo 8 by Jeffrey Kluger, Borman on his first (two-week) romp in space actually tried to hold it in for the duration. Ugh. Why such determination? As far as I recall, he thought the matter, er, manner of disposal was somewhat demeaning and decided a former test pilot's wi...Jump to post

Interesting reading about the DARPA/Boeing project. One designed-in advantage of tail-landing rockets is that the the main thermal and mechanical stresses that result from de-orbit are taken up by the rocket thrusters.

I try to follow Gwynne Shotwell's talks - here's one from April of this year.
Of note, among other things, is how she got into engineering. Her mother was an artist, by the way. See:

And speaking further to parapente's point, while being rather ignorant of specifics, two things I'd like to point out: - Very inconsistent decision making by politicians over time.

Elon Musk - total investment in FH probably more than half a billion. They thought of canceling it several times. Isn't that relatively cheap for a rocket of that size ??? Absolutely.

Came in late.
- could see short hops with the spaceship part of BFR next year. [!!!]
- it's conceivable to see BFR flight to earth orbit in three to four years [and that would be capable of going to the moon too].
- all hands on deck for Crew Dragon, aiming for end of year use.
Wow. 27 rocket engines burning into history. Star Man is in space, ready for his one billion year ride.

The video showing SpaceX's McGregor facilities in Texas is interesting - the entire operation looks very lean and efficient to me. I like it!
Stage 2 with Koreasat-5A is in its transfer orbit and presently awaiting engine relight. This is what brings in the moolah.
Stage 1 has landed on the drone ship in the Atlantic, but last I saw it looked pretty "toasty", as the seasoned commenter described it.
Another two successful launches and landings for SpaceX! It's just great to see things go [and come] so smoothly. More money in the kitty!

And according to Gwynne Shotwell [speaking @MIT some days ago], they'll attempt to recover a Falcon 9's upper stage next year, though not in order to reuse it.
