While never before discovered underneath the surface, these polygonal structures on Mars aren’t exactly a new discovery, as Universe Today explains.For example, NASA spotted them on the surface ...
Scientists discovered signs of an ocean's worth of liquid water miles below Mars' surface. The findings, based on Marsquake measurements by NASA's InSight lander, could help solve a mystery.
The Perseverance rover came across an odd stone on Mars, the likes of which NASA said has never been seen, that people are calling the 'zebra rock.' NASA's Perseverance rover found an unusual ...
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 ...
This means that Mars has lost a volume of water 6.5 times what is stored in today's polar caps. The water for a time would have formed an ocean in the low-lying Mare Boreum. The amount of water could have covered the planet about 140 meters, but was probably in an ocean that in places would be almost 1 mile deep. [1] [2]
The Mars ocean hypothesis proposes that the Vastitas Borealis basin was the site of an ocean of liquid water at least once, [23] and presents evidence that nearly a third of the surface of Mars was covered by a liquid ocean early in the planet's geologic history.
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 ...
Some areas of the surface exhibit scalloped topography, a surface that looks like it was carved out by an ice cream scoop. This surface is thought to have formed by the degradation of an ice-rich permafrost. [16] Many features that look like pingos on the Earth are found in Utopia Planitia (~35–50° N; ~80–115° E). [17]
