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
Rover (space exploration) Agency (ESA) is currently designing and carrying out early prototyping and testing of the ExoMars rover. , the rover is scheduled for launch in 2020. The Mars 2020 rover mission is a Mars rover under development by NASA with a launch planned for 2020. It is intended to investigate an astrobiologically relevant ancient environment on Mars, investigate its surface geological processes and history, including the assessment of its past habitability and potential for preservation of biosignatures within accessible geological materials.
