I'd like to learn more about how the first stage does a veritable about face. I presume that staging happens around 60 miles or so, and probably a few thousand MPH?

![]() As for the speeds, some geek on the SpaceX subreddit crunched all sorts of numbers from the launch... https://docs.google.com/spreadsheets...gid=2057127134 According to the video, boostback started at 3:50 (230 seconds), so that would put it around 98km (58 miles) out and at about 1600m/s (3600 mph).

EDIT: And now the guy has revised his estimates and shows 94 km (58 miles). I give up updating after this though. ![]() Last edited by DaFace; 12-22-2015 at 03:35 PM.. |

Well, since the thread is bumped anyway, I'll just keep posting shit.

One good point that I read today is that this landing could be huge for reliability in addition to reusability. With the exception of the shuttle, we've never been able to open up a flown spacecraft and figure out what points were weakened before. They should be able to look for the weak points and make them stronger, both to boost reusability, but also to make them stronger in the first place.

Hopefully they'll be able to stick the barge landings too next time. |

Don't get me wrong, what BO accomplished was fantastic and should be commended. Hopefully they'll be able to actually launch to orbit and land someday as well. It's just silly to pretend like what they accomplished was even in the same ballpark in terms of difficulty.
