I get forward momentum, maintaining energy in a turn, centrifugal force, centripetal force, and all jazz, but after they use the cold-gas release to flip it, I'm having a hard time wrapping my mind around how does a rocket get going back the other way to make it back over land (in the near weightlessness it's in)? At least not without another burn, or unless the flip is more of a slow turn to allow momentum to ultimately send you back the other way?

I think this diagram is at least reasonably accurate (though it's boosting back further to make it to land). ![]() Also, another thing to keep in mind is that the first stage weighs MUCH less at that point than the original rocket did (given that there's no second stage at all, and a majority of the propellant has already been used up), so it's quite a bit easier to slow down than you might think.

Perhaps a trip to SpaceX (to ask questions) would be a wise vacation for me... ![]() Sent from my phone using Tapatalk (so spelling be damned!!!) |

Official pics are up:

It's gonna be a hell of a sight to see, for sure. I'd almost make a vacation down to Florida to watch if it wasn't for the high likelihood of delays.
