Mars, of course, is very different from Earth. It's a frigid desert constantly bombarded by radiation. There are geological signs that it was a warmer and wetter place once upon a time. One of the mission's goals is to figure out how Mars transformed. After sailing 352 million miles and eight months, Curiosity parked its six wheels near the Martian equator, where it will spend the next two years poking into rocks and soil in search of the chemical ingredients of life. It is the most expensive and ambitious mission yet to Mars. Its ultimate destination is a mountain towering from the center of the crater floor. Preliminary estimates indicate Curiosity landed four miles away from the base of Mount Sharp, thought to contain intriguing signs of past water
-- a starting point to learning whether microbial life could exist. Before the 1-ton, nuclear-powered Curiosity can start roving, it has to undergo several weeks of tedious but essential health checks. Since it was too heavy to land using traditional air bags, it used a heat shield, parachute, rockets and cables. An orbiting spacecraft spotted the discarded spacecraft hardware, including the ballast weights that were shed soon after entry into the atmosphere.
