Especially the innovative way they decided to land the rover which was too big and heavy for the traditional air bag landing.
As the craft enters the atmosphere, it starts slowing and at about 7 miles altitude the parachute deploys.
At about 1 mile altitude the descent craft separates and the powered flight of the hover craft begins.
A rocket powered hover craft descends to about 20 meters, then a rope and pulley system (sky crane) lowers the rover to the surface.
Then the bridal is cut and the hover craft flies away.
It all went as planned and after landing the rover sent the first picture back to earth.
I can't wait for some of the experiments to be complete which are designed to see if life ever existed or is possible on Mars.
