Manned mission to Mars

Concept for NASA Design Reference Mission Architecture 5.0 (2009)

A manned mission to Mars has been the subject of science fiction, engineering, and scientific proposals throughout the 20th century and into the 21st century. The plans comprise proposals not only to land on, but eventually also settle the planet Mars, its moons, Phobos & Deimos and terraform the planet.

Preliminary work for missions has been undertaken since the 1950s, with planned missions typically taking place 10 to 30 years in the future. The list of manned Mars mission plans in the 20th century shows the various mission proposals that have been put forth by multiple organizations and space agencies in this field of space exploration.

In 2004 the U.S. administration announced a new Vision for Space Exploration naming a manned Mars mission as one of its milestones. No concrete plan has been decided upon, and the proposal is currently being discussed between politicians, scientists, space advocates and in the public. In 2010, a new bill was signed allowing for a manned Mars mission by the 2030s.
