At least two-thirds of Mars' surface is more than 3.5 billion years old, and it could have been habitable 4.48 billion years ago, 500 million years before the earliest known Earth lifeforms; [4] Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there.
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
A Mars habitat is a hypothetical place where humans could live on Mars. [2] [3] Mars habitats would have to contend with surface conditions that include almost no oxygen in the air, extreme cold, low pressure, and high radiation. [4] Alternatively, the habitat might be placed underground, which helps solve some problems but creates new ...
Future astronauts exploring Mars would encounter a whole host of challenges if they tried to access the water, because it’s located between 7 and 12 miles (11.5 and 20 kilometers) beneath the ...
Finding water on Mars isn't itself a new discovery; the planet's polar regions are full of ice. But the new research paves the way for future study into Mars' habitability and the search for life ...
The U.S. space agency's Artemis program aims to put astronauts in the coming years on the lunar surface for the first time since 1972 in preparation for potential future human missions to Mars.
