The atmosphere of Mars is a resource of known composition available at any landing site on Mars. It has been proposed that human exploration of Mars could use carbon dioxide (CO 2) from the Martian atmosphere to make methane (CH 4) and use it as rocket fuel for the return mission.

Hypothetical modification of Mars into an Earth-like habitable planet This article is about the technological process. For the board game, see Terraforming Mars (board game). Artist's conception of the process of terraforming Mars. The terraforming of Mars or the terraformation of Mars ...
An artist's conception shows a terraformed Mars in four stages of development.. Terraforming or terraformation ("Earth-shaping") is the hypothetical process of deliberately modifying the atmosphere, temperature, surface topography or ecology of a planet, moon, or other body to be similar to the environment of Earth to make it habitable for humans to live on.
Pine trees have been suggested, in combination with other techniques for creating more hospitable atmosphere on Mars. [83] In situ resource utilization involves using materials encountered on Mars to produce materials needed. One idea for supporting a Mars habitat is to extract subterranean water, which, with sufficient power, could then be ...
A common object of discussion on potential terraforming is the planet Mars. To terraform Mars, humans would need to create a new atmosphere, due to the planet's high carbon dioxide concentration and low atmospheric pressure. This would be possible by introducing more greenhouse gases to below "freezing point from indigenous materials". [2]
Unlike Earth, Mars does not have a global magnetic field to protect its atmosphere, leaving it vulnerable to solar ultraviolet radiation. Scientists crack mystery of Mars' missing atmosphere ...
Mars atmospheric entry is the entry into the atmosphere of Mars. High velocity entry into Martian air creates a CO 2 -N 2 plasma, as opposed to O 2 -N 2 for Earth air. [ 1 ] Mars entry is affected by the radiative effects of hot CO 2 gas and Martian dust suspended in the air. [ 2 ]
There are numerous challenges to human settlements on Mars: lack of breathable oxygen, harmful ultraviolet radiation due to its thin atmosphere, salty soil hostile to growing crops, dust storms ...
