Rover landing area Perseverance From NASA It was a point of discussion to read The red planet Today we can say that it is correct. Rover Perseverance Landed in February 2021 Valley Lake Now, a new article Science Says there was water Tuesday Billions of years ago.
According to pictures taken by the rover Perseverance A Tuesday Within three months of landing, astronomers made the discovery Valley Lake Millions of years ago, it was filled with water as it was supposed to.
New study published in science “Perseverance Rover Reveals Ancient Delta-Lake System and Flood Reservoirs on Mars’ Jessero Valley“An intermediate team of geologists and astronomers was able to analyze the landing site in more detail. Perseverance Due to the images captured by Rover with the help of its Mastcam-Z camera system.
When today Tuesday It is cold and dry and there is no liquid water on its surface because it is not stable and there are signs that it existed billions of years ago. New evidence for this is geological study Valley Lake, Which is about 45 km in diameter and previously stagnant liquid water in the form of a lake.
Of all the layers, researchers are most interested in the bottom, made of sandstone and tiles, and for good reason: like the earth, any living thing that rises in water Lake Probably it settled in the mud and sand at the base. “Our main concern is what we noticed in Kodiak. If there are signs of antiquity in a creation like this, it will usually be in the sandstone, it is below,” Mangold told the Times.
According to the authors of the study, they found two different pieces of evidence for the presence of water in the abyss millions of years ago. The first of these is the stratigraphy of the Kodiak, a small rise in the abyss showing different layers and different layers of rock. Layers formed when water stagnates. The team explains that these sedimentary layers are only kept by a river that flows into a lake.
“The location of the rocks is probably our most amazing discovery,” says Mangold, one of the research scientists. “Delta fans usually have sand and gravel, not rocks. The river here is only 30 to 40 meters wide and a few meters deep, but it was enough to move the rocks.
On the other hand, the images reveal more than 300 small rocks in the upper part of the delta, where ancient rock beds may have broken the edge of the abyss or carried into the abyss via a river that flows there.
The existence of floods, the researchers wrote, a Tuesday Heat and humidity, which may have caused flooding due to the melting of rain or snow, although Mangold admits, this is just speculation.
“We have no evidence Tuesday The origin of this flood. That’s the decent thing to do, and it should end there. ”
“Better and wetter days Tuesday They may be backward, but if there is evidence for an ancient, or existing life somewhere in that distant world, The work you do Perseverance I can express it one day, “Time said.
Thus, the presence of water Tuesday It is important to have a good understanding of what water was like Tuesday What it was like in the past and now, it helps to search for the presence of biological remains and creatures on the planet, One of the main tasks From Perseverance.
