25 years in space? 
  I hope this question is not too far afield (or too morbid), but does anyone know what would happen to a dead body after 25 years of drifting in space inside a spaceship?

Rocket Plane in Level Flight? 
  Would it be possible to design something like the XCOR Lynx for level flight, with a rocket but still have a useable range? Let's say a normal cruise speed, size and passenger capacity competitive with a Lear Jet 23, or a Cirrus Vision.

msl sky crane? 
  Hi, I've been searching for video's and information on testing of the msl sky crane system.

Have test articles been built and tested?... more »
