Water exists on Mars, in accordance with a group of geophysicists, and never simply as ice on its poles or as vapor in its environment. The scientists have found evidence of liquid water deep in its outer crust, primarily based on their evaluation of knowledge offered by NASA’s Mars Insight Lander. Particularly, they analyzed 4 years’ value of floor motions recorded by the lander’s seismometer. By seismic velocities, or how briskly seismic waves journey on the planet, they had been in a position to decide the supplies that the waves moved by. What they discovered was that Mars’ mid-crust has fractured igneous rocks saturated with liquid water.
One of many scientists concerned within the research, Prof Michael Manga from the College of California, Berkeley, informed the BBC that they applied the identical strategies used “to prospect for water on Earth, or to search for oil and gasoline.” He mentioned his group’s findings can reply the query of the place all of the water on Mars had gone, as a result of options on the planet’s floor confirmed that it had lakes and rivers round three billion years in the past. Whereas there is a idea that the majority of that water was misplaced to area, scientists have challenged that concept lately. One research by Caltech and NASA JPL revealed in 2021 discovered information that the majority of that water is still trapped within the planet’s crust.
The scientists concerned on this newer research, revealed in PNAS, had been solely in a position to analyze seismic velocity information taken from beneath the lander. Nonetheless, they consider that related underground water reservoirs exist all around the planet, they usually estimate that there is sufficient liquid water below the floor to type a layer throughout Mars that is half a mile deep. Manga informed the the BBC that “a lot of our water is underground and there is not any purpose for that to not be the case on Mars too.”
Whereas the group’s findings might be taken as excellent news for area businesses and personal firms trying to go to and even type human colonies on the planet, it will not be simple reaching Mars’ water reservoirs. They’re situated round 7 to 12.5 miles beneath the floor, which will not be simple to achieve even on our planet. “Drilling a gap 10km (6 miles) deep on Mars — even for [Elon] Musk — could be troublesome,” Manga mentioned, including that “with out liquid water, you do not have life.”
