The terraforming of Mars or the terraformation of Mars is a hypothetical procedure that would consist of a planetary engineering project or concurrent projects aspiring to transform Mars from a planet hostile to life to one that could sustainably host humans and other lifeforms free of protection or mediation.
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.
The terraforming of Mars is the hypothetical set of planetary engineering projects that would modify Mars to allow terrestrial life to survive free of protection or mediation. Proposals for the terraforming of Mars have been put forward, but there is considerable debate about their feasibility and the ethics associated with terraforming. [75]
Musk does have a plan for making Mars an attractive destination for long-term living: Terraforming, a hypothetical scenario in which humans make Mars more Earth-like by pumping gases into the ...

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]
Mars may have been more like Earth billions of years ago. It once had a thick atmosphere, much like our planet, which would have allowed liquid water to flow on the surface.
The plan focuses on keeping costs down by making use of automated systems and available materials on Mars to manufacture the return journey's fuel in situ. The book also reveals possible Mars colony designs and weighs the prospects for a colony's material self-sufficiency and for the terraforming of Mars.
