Is it actually possible to de-orbit without over-heating?
If you come in at some super shallow angle you'd think you could do it, but at some point one ends up going from an orbit to a trajectory, at which point unless your air resistance can throttle your air speed below some value, you'll always over-heat?
- mrkstu 6y agoI suppose if you had some kind of aero-gel bubble that could progressively ablate as you came down you could make it work.
- cheerlessbog 6y agoIf arbitrary thrust is allowed you can move as slowly as you like in any direction.
- jvm_ 6y agoBleeding off 8km/second (5miles/second) all the way to zero movement - just by moving through the atmosphere... doing that without heating just seems impossible.
- jonathlee 6y agoYes. Look up space diving. There have been old Popular Science (Popular Mechanics?) articles on it and speculation in the space community about a new sport if/when a space tether is possible.
