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

Jefferson Rome and the others discover a room with an alien telemetry system. The probe is drawing up seawater. Jefferson Rome remembers the space probe Surveyor, used to study other nearby planets such as Venus, Mars and Jupiter. The three survivors themselves are being held captive in antiseptic chambers, where they are prey to some strange mutant microbes. Such a mutant microbe, larger than a person,
