Mars Science Laboratory (MSL) is a robotic mission to Mars launched by NASA on November 26, 2011, that will attempt to land a Mars rover called Curiosity on the surface of Mars. Today (August 6, 2012), it is scheduled to land in Gale Crater at about 05:31 UTC. Curiosity rover’s objectives include determining Mars’ habitability, studying its climate and geology, and collecting data for human missions. Curiosity is twice as long and five times as heavy as NASA’s previous rovers Spirit and Opportunity. The total cost of the MSL/curiosity project is about US$2.5 billion.
