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 Crewed Mars rover Crewed Mars rovers are vehicles for transporting people on the planet Mars, and have been conceptualized as part of human mission to that planet. Two types of crewed Mars rovers are pressurized and unpressurizedunpressurized designs may have open seating for a crew in Mars space suits, and another style has a pressurized interior for people to work without a space suit. Pressurized rovers have been envisioned for short trips from a Mars base, or they may be equipped to be more of a mobile base or laboratory. They are also called "manned Mars rovers" Crewed Mars rovers
