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 ...
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.
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.
In the third and tenth chapters, The Case for Mars addresses the politics and costs of the ideas described. The authors argue that the colonization of Mars is a logical extension of the settlement of North America. They envision a frontier society, providing opportunities for innovation and social experimentation.
The third form of rock material found on Earth is metamorphic rock, which is created from the transformation of pre-existing rock types through high pressures, high temperatures, or both. The most abundant silicate minerals on the Earth's surface include quartz , the feldspars , amphibole , mica , pyroxene , and olivine . [ 25 ]
A variety of planetary engineering challenges stand in the way of terraforming efforts. The atmospheric terraforming of Mars, for example, would require "significant quantities of gas" to be added to the Martian atmosphere. [4] This gas has been thought to be stored in solid and liquid form within Mars' polar ice caps and underground reservoirs.
The idea of transforming Mars into a world more hospitable to human habitation is a regular feature of science fiction. Scientists are now proposing a new approach to warm up Earth's planetary ...
The atmosphere of Mars contains a great deal of fine dust particles. [51] Water vapor condenses on the particles, then they fall down to the ground due to the additional weight of the water coating. When ice at the top of the mantling layer goes back into the atmosphere, it leaves behind dust, which insulates the remaining ice. [52]
