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.
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]

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.
A fast Mars mission of 245 days (8.0 months) round trip could be possible with on-orbit staging. [12] In 2014, ballistic capture was proposed, which may reduce fuel cost and provide more flexible launch windows compared to the Hohmann. [13] Three views of Mars, Hubble Space Telescope, 1997
The good news is, you don’t have to have a telescope to enjoy Mars at opposition! Just look up into the sky after sunset, and Mars will be there. It will be hard to miss!
