Giant ice deposits on Mars surfaces could be evidence of hidden polar ice sheets. The findings are presented in NASA’s new study.
The findings show conclusive evidence that the ice deposits on mars are no different from Earth, fluctuating due to the slope and orbit of the planet. The amount of ice stacked into sand deposits is very large. If that sediment is thawed, the liquid will form a planet-wide layer of water about 5 feet deep.
Ice Deposits on Mars
“We do not expect to find this much ice here. That is likely to make it the third largest water reservoir on Mars after polar ice,” said research assistant graduate of the University of Texas for Geophysics and lead author of the study Stefano Nerozzi as quoted by the Daily Mail. Monday (05/27/2019).
Scientists have hypothesized ice deposits on Mars was created during the last ice age and were protected from solar radiation and warming periods by sand covering their surfaces.
Scientists have been suspecting the glacial activity on Mars for long. It was affected by the tilt and shake of the planet against the Sun. For around 50,000 years, the ice sheet was suspected to have completely disappeared from Mars.
“Strangely, the total volume of locked water in that buried polar deposits is about in the same amount as all ice in those already-known glaciers buried at lower latitudes on Mars, and strangely, they are predicted to have the same years,” he said.
This discovery implies not only for how Mars may have seen today. But also how the climate of the Red Planet in the past has been conducive to life as we know it on Earth.
“Understanding how much water is available globally versus what is trapped at the poles is important. If you have liquid water on Mars, you can have all the right conditions for supporting life. But if most of the water is locked at the poles, it will be difficult to get enough water near the equator, “Nerozzi said.
When the prospect of extraterrestrial human colonization becomes bigger and more serious, human habitability on Mars has become a desirable field for the private and public sectors. NASA recently gave a handsome prize for a human-ready habitats concept design that could be produced and replicated on Mars using 3D printing.
Private space company SpaceX, owned by Tesla CEO Elon Musk, also aggressively pursued the first manned space mission to Mars. The Starhopper company, which aims to bring humans to the Moon and Mars, is ready to bring its first flight that can be present on May 28.
