    .@JerboMania: Wouldn't the atmosphere burn most of it? // No. You "burn" slowing from 17,000mph orbital speed, not by falling

        @neiltyson why bother with heat shields? Massive reverse thrust instead? Too much fuel?

        @neiltyson @JerboMania Why don't spacecraft slow down and just fall to Earth instead of the delicate, life and death re-entry at 17,000 mph?

        @neiltyson if the trajectory is steep enough and speed is reduced to subsonic speeds, would a "burn" still occur?

        @neiltyson So, if the ISS somehow went from 17000mph to 0mph, then fell (like Baumgartner, but higher up), it would be mostly intact?

        @neiltyson @JerboMania That's why the man "who jumped from very high" didn't burn I suppose.

        @neiltyson Wait, so does that mean that a human body equipped with a parachute could survive re-entry if it was traveling slow enough?

        @neiltyson @JerboMania But Earth's girth is more than approx 21,000 miles isn't it? So how does ISS get round it in 90 minutes?

        @neiltyson So could someone "skydive" from that height? At some height would they need to consider their speed and hitting the atmosphere?
