Oceans of water may be trapped deep beneath the Martian surface | CNN
A new analysis of data collected by NASA’s InSight mission suggests there may be enough water beneath the surface of Mars to cover the planet.
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 surface, according to the study published Monday in the journal Proceedings of the National Academy of Sciences. Mars was likely a warmer, wetter place billions of years ago, based on the evidence of ancient lakes, river channels, deltas and rocks altered by water studied by other NASA missions and observed by orbiters. The idea that liquid water may exist deep beneath the Martian surface has been around for decades, but this is the first time real data from a Mars mission can confirm such speculation, said Alberto Fairén, a visiting interdisciplinary planetary scientist and astrobiologist within the department of astronomy at Cornell University.
