The exploration of terrestrial analogues provide clues as to how and where best look for signs of life on Mars. [49] Impactite, shown to preserve signs of life on Earth, was discovered on Mars and could contain signs of ancient life, if life ever existed on the planet. [50]
The contrasts between these arguments are fully explored in the field of environmental ethics. Debates often focus on how much time and effort should be expended on investigating the possibility of any microscopic life on a planet before deciding whether to terraform, and what level of sophistication or chances for future development alien life would deserve varying levels of commitment to non ...
In its ancient past, Mars likely contained many of the necessarily ingredients for microbial life to flourish on its surface. Now, a new discovery by NASA’s Perseverance rover shows a trifecta ...

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.
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
In the age of Plato, the Greeks called the planet Ἄρεως ἀστἡρ (Areos aster), or "star of Ares".
