Life on Mars Ca(ClO) in the Phoenix soil has not interacted with liquid water of any form, perhaps for as long as 600 Myr. If it had, the highly soluble Ca(ClO) in contact with liquid water would have formed only CaSO. This suggests a severely arid environment, with minimal or no liquid water interaction. The Mars Science Laboratory mission is a NASA project that launched on November 26, 2011, the "Curiosity" rover, a nuclear-powered robotic vehicle, bearing instruments designed to assess past and present habitability conditions on Mars. The "Curiosity" rover landed on Mars on Aeolis Palus in Gale Crater, near Aeolis Mons
Crewed Mars rover are a component of many designs for a human mission to the planet Mars. For example, the Austere Human Missions to Mars proposal proposed including two rovers on its unmanned power and logistics cargo lander. Each rover could hold a crew of two in a pressurized environment, with power coming from a Stirling radioisotope generator. Mars One, a Mars colonization plan intended to be funded by a TV show, plans an unpressurized crewed rover capable of traveling 80 km (50 miles). They said a possible supplier was Astrobotic Technology. The Manned Mars Exploration Rover (MMER) won a design award in
