Life on Mars If the surface life has been reanimated as recently as 450,000 years ago, then rovers on Mars could find dormant but still viable life at a depth of one meter below the surface, according to an estimate. In 1965, the Mariner 4 probe discovered that Mars had no global magnetic field that would protect the planet from potentially life-threatening cosmic radiation and solar radiation; observations made in the late 1990s by the Mars Global Surveyor confirmed this discovery. Scientists speculate that the lack of magnetic shielding helped the solar wind blow away much of Mars's atmosphere over the course of
Mars Microspacecraft Missions Mars Microspacecraft Missions Mars Microspacecraft Missions are proposed cheap launch missions costing less than $50 million that can be carried out by the Italian Space Agency to Mars to research Mars, ranging from the use of one spacecraft to multiple constellations of mini spacecraft. Under a study contract, the Italian Space Agency (ASI) developed the mechanical system concept for a Mars Microspacecraft to launch in a twin configuration on an Ariane V ASAP (Auxiliary Payload). As a member a multi-disciplined team, ASI developed the mechanical configuration and preliminary structure design for the spacecraft in two configurations, a probe carrier and
