Shuttle reentry profile
WebOct 14, 2015 · Without them, the shuttle will still reenter, but it will follow a 'skip reentry' profile, essentially bouncing off the upper atmosphere until it bleeds off a large amount of energy, then sinking like a rock, resulting in … WebJan 16, 2015 · Mercury astronauts took about 11g peak force on re-entry, Apollo about 6.5-7g. The space shuttle was amazingly gentle, with reentry force peaking at just 1.6g. Again, Soyuz does about 4g here, I think. There may be a pretty good jolt at touchdown/splashdown, too. Some of the Apollos hit rising waves at the end of the ride …
