An artist's impression of ancient Mars and its oceans based on geological data The blue region of low topography in the Martian northern hemisphere is hypothesized to be the site of a primordial ocean of liquid water. [1] The Mars ocean theory states that nearly a third of the surface of Mars was covered by an ocean of liquid water early in the ...
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 ...
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.

Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests. The findings released Monday are based on ...
These geomorphic features suggest Mars had an ocean on its surface and river networks that resemble current Earth's during the late Noachian (4.1–3.7 Ga). [ 37 ] [ 38 ] It is unclear how Mars's orbital pattern, which places it even further from the Sun, and the faintness of the young Sun could have produced what is thought to have been a very ...
The Mars-themed rental property could be open by year's end – and to a thunderous launch. The Mission to Mars property is 15,000-square-feet and valued at $12 million, its developer said.
Research and theory in this regard is a component of a number of natural sciences, such as astronomy, planetary science and the emerging discipline of astrobiology. An absolute requirement for life is an energy source, and the notion of planetary habitability implies that many other geophysical , geochemical , and astrophysical criteria must be ...
