The exact causes are not well understood but may be related to a combination of processes including loss of early atmosphere, or impact erosion, or both. [36] Billions of years ago, before this degradation, the surface of Mars was apparently fairly habitable, consisted of liquid water and clement weather, though it is unknown if life existed on ...

Finding fossils of microscopic life of such distant times is an incredibly difficult task, even for Earth's earliest known life forms. Such fossils require a material capable to preserve cellular structures and ...
Cavosie said the research showed that even though Mars’ crust was hit by massive meteorites that caused a major upheaval of the planet’s surface, water was present during the early Pre ...
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 ...
