Human mission to Mars Human mission to Mars A human mission to Mars has been the subject of science fiction, aerospace engineering, and scientific proposals since the 19th century. The plans comprise proposals to land on Mars, eventually settling on and terraforming the planet, while utilizing its moons, Phobos and Deimos. The exploration of Mars has been a goal of national space programs for decades. Preliminary work for missions that would involve human explorers has been undertaken since the 1950s, with planned missions typically being stated as taking place 10 to 30 years in the future when they are drafted.
