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
Revenge of the Mysterons from Mars survey the Mysterons' planet, Mars, with a space probe is threatened when a scientist attached to the project is killed and duplicated by the Mysterons ("Shadow of Fear"). After the Lunar Controller boldly declares the Moon's independence from Earth in its fight against the Mysterons, Captains Scarlet, Blue and Lieutenant Green are dispatched to the colony Lunarville 7 to investigate reports of an unidentified complex being built on the far side of the Moon ("Lunarville 7").
