would a pillow burn up on reentry?

Ok, that’s just awesome. Good to see that science hasn’t lost its sense of humout.

Is it even conceivable to make a suit designed for reentry? With a big airbag around it or something? It wouldn’t be useful for spacewalks, of course. It would just be a parachute for outer space.

Check the MOOSE, there was another design I remeber, but I can´t find it right now. It was basically the same thing except that the heath shield was round, and IIRC wasn´t inflatable.

Ok, I found the mother lode, check out the EGRESS, ENCAP, and specially the Paracone and SAVER.

excellent! Thanks.

The suborbital dives from up to 100km will be the proving ground for the control and life support systems required for emergency re-entry systems from orbit.

Plus adrenaline junkies are more likely to spend money repeatedly on jumping out of a spacecraft through the atmosphere.

Just wanted to chime in that I understood about 10% of your maths post, but enjoyed it 100%. Well done! I particularly liked:

“More significantly, perhaps, it’s carrying some 31 megajoules of energy that must be dissipated in a non-conflagratory manner before it nestles to earth in a manner that supports crucial vertebrae while suppressing the causes of snoring.”
