Scientist found liquid body water on Mars!

Mars could be our second home planet. Nasa prepraing to send a rover on mars which will make oxyen on mars atmosphere. In the other hand, scientist also said that they have found liquid body water on Mars.......                                                                                                                                                                                           After decades of discussion, scientists have noticed hints of liquid water unfree below the planet’s south polar ice cap.

A team of Italian researchers analyzed ANd ranging|radiolocation|measuring instrument|measuring system|measuring device} knowledge taken between might 2012 and Dec 2015 with an instrument on board the eu house Agency’s Mars satellite, in step with a brand new paper. elements of the ice came strange signals within the instrument.

“We interpret this feature as a stable body of liquid water on Mars,” the authors write within the-paper printed these days in the journal Science.

At now, there’s many proof that Mars accustomed have-liquid water, supported its topography and alternative clues. and clearly the world has frozen water, as proved  by its ice caps. however whether or not there’s liquid water presently, either within the dirt or hidden below its poles, has long been a matter {of discussion|of dialogue|of discussion} and debate.

The bright reflection tacit that the region had a far higher worth of its material permittivity, a vital electrical property for learning penetrating measuring device. The researchers weighed the options: might greenhouse gas ice have caused the signal, or another material? Their analysis urged that, no, the foremost seemingly rationalization would be water, that includes a a lot of higher material permittivity than ice. That water would have many dissolved salts, either as a brine pool or a sludge wherever water saturated soil, in step with the paper.

Why doesn’t the water freeze? initial, there’s the dynamics of ice sheets, which may expertise sub-surface melting because of the particular pressure and temperature setting (as they are doing on Earth). Then there’s the dissolved salts. you may keep in mind the phrase “perchlorates” from past Mars water studies—these area unit molecules that contain halogen atoms coupled to four chemical element atoms. The presence of salt salts will greatly cut back the freezing point of water.

“There’s one thing there, no matter it's.”

“The temperature at the lowest of the south polar cap supports the concept that this might be liquid water, as a result of it’s in a very brine wherever perchlorates might have down the freezing point thus it may be stable at this temperature,” Tanya Harrison, director of analysis for Arizona State University’s NewsSpace initiative, told Gizmodo. Harrison wasn't concerned within the current analysis, however has studied Mars within the past.

The measuring device scientists Gizmodo spoke to were convinced by the info and were cautiously optimistic regarding the interpretation. “You can’t argue with the measuring device results,” huisache Stuurman, a measuring device individual presently to hitch the eu house Agency, told Gizmodo. “It’s clear they need AN anomalously bright region, that will imply one thing with abnormal properties.”

As for whether or not it’s actually liquid water, “I can’t think about one thing that may generate a similar results,” she said. “The interpretation is up for discussion,” and is already the topic of dialogue within the planetary science community. “There’s one thing there, no matter it's.”

This detection is that the next huge hint the mystery of whether or not liquid water still exists in measurable quantities on the Mars these days. you may be conversant in the “recurrent slope lineae,” or RSLs, on the planet—streaks on its surface that seem to darken. A much-hyped paper proclaimed this as “strong-evidence” for liquid water heater in 2015, however another, recent paper urged there may be a higher rationalization for the darkening. This new paper offers another, most likely unrelated supply of liquid water.

“This story provides confirmation that liquid water will exist on Mars,” Lujendra Ojha, author of the 2015 RSL paper from Johns Hopkins University, told Gizmodo. “It’s likely to be transient and salty, it'll presumably be submerged... however i feel it’s a touch of vindication.” And if it exists within the ice caps, maybe it exists elsewhere, just like the RSLs. 

There’s heaps a lot of work to try and do. A visit to Mars with the proper tools is what would be required to verify or rule out the presence of liquid water. And, of course, this new paper says nothing regarding the presence of life—it’s unclear what reasonably organic structure, if any, might survive during this cold brine. however a standing body of water is often intriguing.

“Anywhere we discover liquid water on Earth, we tend to tend to search out life,” aforementioned Harrison. “Even in ice cores from Greenland, there area unit microorganism and alga living in pockets or hanging get into a dormant state. If there’s briny liquid water, it'd be a touch abode for a few reasonably life to survive.”
