Mars base
Mars base, computer artwork. The first bases on Mars are likely to resemble chemical plants. They will have sealed buildings to protect astronauts from the thin atmosphere that is nearly all carbon dioxide, and the freezing surface temperature that ranges from -89 to -31 degrees Celsius. Inside the central dome, there are plants that will help recycle the carbon dioxide into oxygen, and also provide food. The tanks around the base will store oxygen, water, fuel and other chemicals. One plan involves a base on Mars manufacturing fuel for the return journey to Earth. The rover (lower left) is suited for exploring the arid desert terrain. Mars has a gravity around a third of that of Earth.
