A human mission to Mars has been the subject of science fiction, 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.
'Mars From Deimos' 1956. Hardy's description: 'The dumbell-shaped spaceship (designed by Arthur C. Clarke) shown in the previous 'space station' image has arrived, touching down lightly in the low gravity of Mars's little outer moon, Deimos. The polar cap is clearly visible, and at that time it was still considered possible that the dark areas on Mars were caused by vegetation, fed by the melting caps. On the right of the planet is Phobos, the inner moon. #mars
Stickney Crater Image Credit: HiRISE, MRO, LPL (U. Arizona), NASA Stickney Crater, the largest crater on the martian moon Phobos, is named for Chloe Angeline Stickney Hall, mathematician and wife of astronomer Asaph Hall. Asaph Hall discovered both the Red Planet's moons in 1877. Over 9 kilometers across, Stickney is nearly half the diameter of Phobos itself, so large that the impact that blasted out the crater likely came close to shattering the tiny moon.
