Description
Astronaut on Mars. Artwork of an astronaut on Mars standing next to a US flag. The Martian atmosphere is mostly carbon dioxide and surface temperatures are well below freezing. Martian astronauts will have to breathe their own air supply and wear heated spacesuits. Mars is a rocky desert world and has no surface water. The gravity is about one third of that on Earth. Human missions to explore Mars have been planned since the 1950s, usually involving a period of 10 to 30 years to develop the necessary technology and resources.
