Lidé na Marsu? Už za dvacet let, tvrdí vědci

A view of the night sky above the Mars Desert Research Station (MDRS) is seen outside Hanksville in the Utah desert March 2, 2013. The MDRS aims to investigate the feasibility of a human exploration of Mars and uses the Utah desert's Mars-like terrain to simulate working conditions on the red planet. Scientists, students and enthusiasts work together developing field tactics and studying the terrain. All outdoor exploration is done wearing simulated spacesuits and carrying air supply packs and crews live together in a small communication base with limited amounts of electricity, food, oxygen and water. Everything needed to survive must be produced, fixed and replaced on site. Picture taken March 2, 2013.
