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
Hope Mars Mission constellations in relation to the Sun. It will be equipped with two sets of rocket thrusters, which include four to six large delta V thrusters and eight to 12 small Reaction Control System (RCS) thrusters. The function of the delta V thrusters will be speed management, slowing down the probe or speeding it up as per requirements, while the RCS thrusters will be used for delicate manoeuvring. The reaction wheels within the probe will allow it to reorient itself while travelling through the space, helping it point its antenna towards Earth or point any scientific instrument towards Mars. To achieve
