A new study by the US Aerospace and Space Administration (NASA) revealed the possibility of large quantities of water in the crust of Mars, which did not enter the atmosphere of the red planet, unlike what was thought long ago.
Previous NASA research indicated that Mars was wet enough to cover its entire surface with an ocean of water ranging from 100 to 1500 meters deep, and contains about half of the water in the Earth's Atlantic Ocean.
Scientists believed that the Red Planet had lost its magnetic field and stripped it of solar radiation and the solar winds of a lot of air and water.
The new research indicates that a large amount of its water, between 30 and 99 percent, is "trapped" within minerals in the planet's crust, which "represents a challenge to the current theory that, due to the low gravity of the red planet, its water seeped into space," according to a NASA statement published Tuesday.
It is worth noting that NASA's "Perseverance" mission, which reached Mars, on February 18th, seeks to verify the existence of life on the planet and to explore sites of water bodies or rivers.
The "NASA" discovered for the first time evidence of the existence of water on the surface of Mars, about 20 years ago, but previous indications indicated that it is mostly frozen and centered at the poles.
And in 2011, images released by the agency showed evidence of water flowing on some of the slopes of Mars, during its warm months that stretch from late spring to summer and fade away in winter.
