I have to say I'm completely impressed with the landing of the Curiosity probe early this morning. I watched a documentary on BBC iPlayer a few nights ago and, after seeing the huge number of things that could go wrong with this incredibly complicated landing, its amazing everything worked as planned. A real feat of human technology. Basically atmosphere entry with heatshield, followed by a drone chute slowdown, then heat shield exit, deployment of 'skycrane' with retro-rockets which then lowers the rover to the surface via cables, cables cut and skycrane moved out of way. Amazing.
