Nasa in their latest mission which started on August 2012. The mission was to find out if the Planet called Mars ever had a living thing or if anything had lived on it. The journey to Mars is estimated to be more than half a billion kilometers where the Nasa space ship landed successful few kilometers from the original target. The successful landing came as exciting news to Nasa Engineers after several attempts to land on the planet failed.
