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 thrusters will be responsible for the delicate maneuvering. The expected travel time of the "Hope" probe is about 200 days at a speed of up to 40,000 km/h on its journey of 60 million kilometres. Upon arrival at Mars, it will study the atmosphere of Mars for two years. It is planned that its instruments will help build "holistic models" of the Martian atmosphere. The data is expected to provide additional data on the escape of the atmosphere to outer space. The "Hope" probe will carry three scientific instruments to study the Martian atmosphere, which include a digital camera for
