Luke Posted December 22, 2015 Author Report Posted December 22, 2015 Elon Musk Verified account @elonmusk It is, however, important to clear up the difference between "space" and "orbit", as described well by https://what-if.xkcd.com/58/
Luke Posted December 22, 2015 Author Report Posted December 22, 2015 Elon Musk Verified account @elonmusk 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.
Luke Posted December 22, 2015 Author Report Posted December 22, 2015 Elon Musk Verified account @elonmusk Jeff maybe unaware SpaceX suborbital VTOL flight began 2013. Orbital water landing 2014. Orbital land landing next. https://m.youtube.com/watch?v=2t15vP1PyoA …
