Mars Rover Curiosity which launched from Earth on November 26, 2011 will land on Mars on August 6th.
There are currently two rovers on Mars- Spirit and Opportunity. However, NASA lost contact with Spirit after a harsh winter and the rover not being able to capture enough sunlight for the solar panels to operate in 2010.
