Location: Pittsburgh PA, USA  I have more faith that it can
work. The skycrane is kind of an evolution of the airbag system
used on Mars Pathfinder. In both cases, jets reduce the velocity
of the craft to zero. The differences:  Pathfinder was cut from
a higher altitude, so it had to bounce, hence the reason for the
airbags.  Curiosity jettisons it's exterior shell (to save
weight) before firing its engines to slow its decent. It goes to
0 velocity much lower to the ground, so the rover is lowered
gently.  There are big differences, but much of it is just an
evolution of earlier systems. Jimmy_C is offline   Reply With
