@elonmusk -298 deg F. Godspeed.
Elon Musk
@elonmusk · Dec 18, 2015
-340 F in this case. Deep cryo increases density and amplifies rocket performance. First time anyone has gone this low for O2.

Falcon 9 is vertical on the launch pad at Cape Canaveral. Working towards static fire. Deep cryo liquid oxygen presenting some challenges.

@elonmusk will the browser be updated in 7.1? the current webkit version is 5 years old which prohibits using fancy new javascript
Elon Musk
@elonmusk · Dec 10, 2015
Agreed. Working on it.

@elonmusk @JeffBezos And of course Armadillo and others earlier, but still, 100km and safely back to pad is a first! Congrats!

@elonmusk · Nov 24, 2015
Yep, good points. I hope you get back into space some day!

But credit for 1st reusable suborbital rocket goes to X-15
And Burt Rutan for commercial

Jeff maybe unaware SpaceX suborbital VTOL flight began 2013. Orbital water landing 2014. Orbital land landing next.

The rarest of beasts - a used rocket. Controlled landing not easy, but done right, can look easy. Check out video: bit.ly/1OpyW5N

@elonmusk · Nov 24, 2015
Not quite "rarest". SpaceX Grasshopper rocket did 6 suborbital flights 3 years ago & is still around.

@elonmusk I understand the difference, however your first stage rocket wouldn't have achieved orbit either, before coming in for a landing?
Elon Musk
@elonmusk · Nov 24, 2015
The F9 booster can reach low orbit as a single stage if not carrying the upper stage and a heavy satellite.

It is, however, important to clear up the difference between "space" and "orbit", as described well by what-if.xkcd.com/58/
Elon Musk
@elonmusk · Nov 24, 2015
Getting to space needs ~Mach 3, but GTO orbit requires ~Mach 30. The energy needed is the square, i.e. 9 units for space and 900 for orbit.
