Nasa has announced that Curiosity Rover has landed on Mars Safely on August 5th, 2012. "We are wheels down on Mars," was the official word from mission control. Engineers immediately erupted into applause, hugs, and a few tears. And, Curiosity had started sending images of Mars. The first images came from Curiosity's cameras, showing pebbles, dust, and the shadow of the rover on the surface of Mars. After a few days of warm-up, the one-ton nuclear powered Curiosity rover will be able to begin its primary mission of sampling and drilling the Martian surface for signs of habitability. While the rover will use its toolkit to perform important field geology on the Red Planet, its main mission will be to determine if Mars is now or could ever have been a site to host life. Over its two-year initial mission, Curiosity will drill, sample, and laser-shoot rocks on the Martian surface to figure out what minerals and elements they contain. In particular, the probe will search for organic carbon that could indicate fossilized life forms. Even more exciting, the rover will also sniff the Martian atmosphere for gasses such as methane that could be a sign of present-day life.
