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 or vapour, to help understand how and why Mars is losing its hydrogen and oxygen into space, and the connection between the upper and lower levels of the Martian atmosphere. Data from the "Hope" probe will also help to model the Earth's atmosphere and study its evolution over millions of years. All data gained from the mission will be made available to 200 universities and research institutes across the globe for the purpose of knowledge sharing. The robotic probe to be sent to Mars under the Emirates Mars Mission has been named 'Hope' or "Al-Amal" in Arabic (), as it
