NASA moves forward with big Mars exploration plan. Launching newest generation of robotic explorers in 2011. NASA is close to a deal to merge its Mars program with that of ESA - European Space Agency. This is a big step towards manned Mars missions. INCREDIBLE success of Mars expedition 2004. Rovers Spirit and Opportunity were supposed to survive 90 days exploring, yet they function to this day, 6th year. But Spirit got stuck in the sand and maybe it is lost for moving around. Next Mars rover Mars Science Laboratory - MSL - weights 1 ton and size of a small automobile. ... Huge discovery over past years - there is very likely methane in the Mars atmosphere.
