Terraforming of Mars

The terraforming of Mars is the hypothetical process by which the climate, surface, and known properties of Mars would be deliberately changed with the goal of making it habitable by humans and other terrestrial life, thus providing the possibility of safe and sustainable colonization of large areas of the planet. The concept relies on the assumption that the environment of a planet can be altered through artificial means; the feasibility of creating a planetary biosphere is undetermined.
