NASA robots craft that will be designed to fly in a formation. The Mars rover Curiosity is a mobile laboratory that was launched from Cape Canaveral in 2011. The Curiosity landed on Mars surface August 6, 2012. This was the largest rover NASA has put on Mars, being twice as long and five times as heavy as its processors. Despite the extra size the Curiosity took many design elements from the previous generation of Mars rovers such as six wheel drive, rocker-bogie suspension, and cameras mounted to the mast of the rover to help the mission's team direct the rover. However unlike
Mars sample-return mission request of NASA and the NSF, declared a MSR campaign its highest priority Flagship Mission for that period. In particular, it endorsed the proposed Mars Astrobiology Explorer-Cacher (MAX-C) mission in a "descoped" (less ambitious) form, although this mission plan was officially cancelled in April 2011. In September 2012, the United States' Mars Program Planning Group endorsed a sample-return after evaluating long-term Mars' plans. The key mission requirement for the planned Mars 2020 rover is that it must help prepare NASA for its MSR campaign. which is needed before any crewed mission takes place. Such effort would require three additional vehicles:
