NASA discovers a rock that hides traces of life on Mars [여기는 화성]

House science media House.com reported on the twenty fifth (native time) that NASA’s Mars exploration rover ‘Dearness’ discovered rocks with indicators of historic life on Mars.

NASA scientists found an attention-grabbing rock within the form of an arrowhead inside a rock nicknamed ‘Cheyava Falls’ on Mars.

Perseverance’s tools collected samples from this web site and located natural compounds which might be precursors to the chemical elements of life. The researchers defined that this reveals indicators of microbial life on Mars billions of years in the past on the floor of Mars.

NASA researchers discovered white veins within the rock, that are believed to be the place water flowed by way of cracks within the rock and deposited calcium sulfate. Operating alongside the rock is a stream of calcium sulfate, which is believed to be important for all times as a result of mineral deposits that after penetrated the rock.

Within the pictures taken by the rover, the researchers discovered dozens of vivid specks a couple of millimeter in dimension surrounded by iron ​​​​​​​​​​and phosphate between the white stripes. Every of those is surrounded by a black ring and appears like leopard spots. This ring accommodates iron and phosphate and is the results of a chemical response pushed by microorganisms which might be additionally discovered on Earth.

“Spots like this are actually stunning,” mentioned Professor David Flannery from the Queensland College of Expertise in Australia “On Earth, these rock options are sometimes related to fossilized microorganisms that dwell underground. “

Chejava Falls is positioned on the sting of the Neterva Gorge, a dry river channel that leads into the Jezero crater on Mars. Scientists consider that this historic channel was carved a very long time in the past as water flowed into the Jezero rift. One doable situation is that mud, which already contained natural matter, was dumped into the valley and hardened into the rocks of Eas Cheyaba. The reason is that water seeped into the fashioned rock a second time, creating the calcium sulfate blood vessels and ring-shaped black spots that researchers see at present.

Nonetheless, scientists say that this alone isn’t conclusive proof that life exists on Mars. For instance, it’s doable that the calcium sulfate seen this time throughout volcanic exercise entered the rock at a temperature too excessive for all times, creating these spots.

Due to this fact, to search out out what actually occurred within the historic river valley billions of years in the past, samples of Cheyaba Falls have to be introduced again to Earth for detailed examine.

Nonetheless, to return Mars samples to Earth, you might want to launch a spacecraft from Earth, place a rover on the floor of Mars, acquire samples, after which carry it again to Earth. It has been reported that the price of latest Mars pattern return efforts has risen to about $11 billion (about 15.24 trillion gained).

At the moment, NASA says it’s searching for concepts from exterior firms on easy methods to carry Mars samples to Earth quicker and at a decrease value. To review this, NASA has signed contracts with seven firms and is conducting three research of its personal.
