The launch window for the curiosity rocket is from 11/25 to 12/18. To escape earths gravity the rocket must travel at 11.2 km/sec. It will take the spaceship 9 months to get to Mars.

Parts of the Rocket

Steer in a series of S-curves during the descent of mars atmosphere. 3 minutes before take down a parachute is used to slow down the rocket. Retro rockets are also used to slow down the spacecraft. In the final seconds the used a sky crane to lower the upright rover onto land. There is a target area of 12 miles long.
