I was wondering how launching from and returning into atmospheres of other bodies such as Mars, Venus, Titan, etc. would differ from Earth's.

Specifically, I am wondering how many g's would be experienced by the crew.

Is there likely to be large differences, or would missions be designed differently to produce accelerations on the crew similar to what modern Earth launches and reentries do?

  • $\begingroup$ What do you mean exactly? All planets have differing gases and different pressures. The only unique thing about Earth's atmosphere is that it is currently ideal for humans and other terrestrial life to survive. $\endgroup$ – Rory Alsop Nov 1 '20 at 15:54
  • $\begingroup$ Questions are usually required to be somewhat specific (this is not a forum). Can you clarify what you are looking for? And what differences you are already aware of? $\endgroup$ – SE - stop firing the good guys Nov 1 '20 at 15:55

    $\begingroup$ @aitia Now that's much more answerable. You should edit your question to reflect this. $\endgroup$ – SE - stop firing the good guys Nov 1 '20 at 16:02

    $\begingroup$ The relationship is very indirect, at best, and distant enough to make me wonder if there is some misconception behind the question...it's much more a matter of vehicle design than of the atmosphere. $\endgroup$ – Christopher James Huff Nov 1 '20 at 22:05
