Life on Mars life were found. Mariner 4 probe performed the first successful flyby of the planet Mars, returning the first pictures of the Martian surface in 1965. The photographs showed an arid Mars without rivers, oceans, or any signs of life. Further, it revealed that the surface (at least the parts that it photographed) was covered in craters, indicating a lack of plate tectonics and weathering of any kind for the last 4 billion years. The probe also found that Mars has no global magnetic field that would protect the planet from potentially life-threatening cosmic rays. The probe was able to calculate
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
