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
Mars Microspacecraft Missions Mars Microspacecraft Missions Mars Microspacecraft Missions are proposed cheap launch missions costing less than $50 million that can be carried out by the Italian Space Agency to Mars to research Mars, ranging from the use of one spacecraft to multiple constellations of mini spacecraft. Under a study contract, the Italian Space Agency (ASI) developed the mechanical system concept for a Mars Microspacecraft to launch in a twin configuration on an Ariane V ASAP (Auxiliary Payload). As a member a multi-disciplined team, ASI developed the mechanical configuration and preliminary structure design for the spacecraft in two configurations, a probe carrier and
