NASA Confirmed That MARS Have Salty Liquid Water Flows On The Planet’s Surface

NASA’s Mars Reconnaissance Orbiter has captured the strongest evidence yet that salty liquid water flows on the planet’s surface during warm seasons.

Whether or not these salty flows could sustain life depends on how salty they are, says Lujendra Ojha of the Georgia Institute of Technology in Atlanta, who has reported the findings, along with his colleagues. “If the water is completely saturated with perchlorates [hydrated salts], then life as we know it on Earth wouldn’t be able to survive in that sort of concentrated water,” he says. “But if the water only has a tiny percentage of perchlorates in it, then I think we should be fine.

Salts can absorb water from the atmosphere and lower the freezing point of water, making it possible for liquid water to exist even in the cold Martian climate. Spectral data from four locations with recurrent slope lineae reveal the presence of hydrated salts, which are most likely to be magnesium perchlorate, magnesium chlorate and sodium perchlorate.

Although not examined in the current study, raising the possibility that the Curiosity rover could look for more clues up close.
Confirmation of flowing water on the surface would add substantial weight to calls for NASA to commit more strongly to searching for life on Mars. In the Atacama desert, one of the most hostile environments on Earth, communities of microbes are able to survive on moisture in the ground created by salts absorbing water from the atmosphere. Some think, similar microbes could live on Mars.

A number of astrobiologists criticised NASA when plans for its next rover, Mars 2020, left out DNA sequencers and other devices designed to look for living organisms.

But many scientists would not be convinced by evidence from a rover. Definitive proof of life on Mars would require samples to be brought back to Earth. Mars 2020 will store samples to be brought home in a later mission.
