If all goes according to plan, InSight will hurtle through the top of the thin Martian atmosphere at 19,310 kilometres per hour. Slowed by friction, deployment of a giant parachute and retro rockets, InSight will descend 124 kilometres through pink Martian skies to the surface in 6-1/2 minutes, traveling a mere 8 kilometres per hour by the time it lands.
Yawn.Call me when they start putting people on mars.
