Suara.com – Recent research NASA found that the oceans were probably buried beneath the crust Mars and didn’t disappear as previously thought.
Previous studies stated that Mars once had enough water to cover the entire surface of the planet with oceans of water about 100 to 1,500 meters deep or about half the water from the Atlantic Ocean on Earth.
However, Mars’ environment is currently cold and dry. Previously, scientists thought that after the Red Planet lost its protective magnetic field, solar radiation and solar wind removed most of its atmosphere and water.
But the new findings suggest it is unlikely that Mars will lose all of its water.

Data from the MAVEN mission (Mars Atmosphere and Volatile EvolutioN) NASA and the European Space Agency’s (ESA) Mars Express orbiter revealed that at such a rate, Mars would only lose about three to 25 meters of global water oceans for 4.5 billion years.
Now experts are finding most of the water Mars once had was probably hidden under the planet’s crust, locked in rocky crystalline structures beneath the Martian surface.
In the findings published in the journal Science on March 16, scientists used data from rovers and spacecraft orbiting Mars as well as the Martian meteorite.
This is to develop a Red Planet model that estimates how much water the planet has and how much water it may have lost over time.
One way scientists estimate how much water Mars lost involves analyzing hydrogen levels in the atmosphere and its rocks.

Each hydrogen atom contains one proton in its nucleus, but some hydrogen atoms have extra neutrons, forming an isotope known as deuterium. Ordinary hydrogen can escape planetary gravity more easily than the heavier deuterium.
