Learn about ongoing missions to Mars and the long history of Mars exploration! Beginning in August 2012, we’ll present a series of webcasts about the Mars Science Laboratory mission and the newest rover, Curiosity. In over 30 previous webcasts, we’ve reported on the activities and discoveries of the Mars Exploration Rovers, Spirit and Opportunity, and the Mars Phoenix Lander.
