Mars Science Laboratory Mars Science Laboratory Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully landed "Curiosity", a Mars rover, in Gale Crater on August 6, 2012. The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a manned mission to Mars. The rover carries a variety of scientific instruments designed by an international team. MSL successfully carried out the most accurate Martian landing of any known spacecraft, hitting a small target landing ellipse of only , in the Aeolis Palus region of Gale Crater.
Mars landing heat flow from the deep interior of Mars, was launched on May 5, 2018. It landed successfully in Mars's Elysium Planitia on November 26, 2018. Additional future missions are the Mars 2020 rover, the Chinese Mars Global Remote Sensing Orbiter and Small Rover, and the Indian Mars Orbiter Mission 2 orbiter. The ESA ExoMars rover, also planned for launch in 2020, should obtain soil samples from up to 2 meters depth and make an extensive search for biosignatures and biomolecules. There is a proposal for a Mars Sample Return Mission by ESA and NASA, but this has been delayed until
