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.
ExoMars (rover) ExoMars (rover) The ExoMars rover is a planned robotic Mars rover, part of the international ExoMars programme led by the European Space Agency and the Russian Roscosmos State Corporation. The plan calls for a Russian launch vehicle, an ESA carrier module and a Russian lander that will deploy the rover to Mars' surface, scheduled to launch in July 2020. Once safely landed, the solar powered rover would begin a seven-month (218-sol) mission to search for the existence of past life on Mars. The ExoMars Trace Gas Orbiter, launched in 2016, will operate as the rover's data-relay satellite. The rover is
