Photographs from NASA’s Perseverance Rover show ancient flash floods on Mars

New research The team behind NASA’s Perseverance Mars Rover reveals the experience of the territory of Mars, especially Jezero Crater, who believes scientists hold the key to life on ancient Mars. “important” Flash floods carved into the rocky wasteland seen today.

The team says it has based on images taken by Rover of sediments collected on the edge of an ancient river that waters the lake in the Jezero Crater.

Photos taken during the landing on February 18 and released Thursday suggest that billions of years ago, Mars had a thick atmosphere that could support large amounts of water. The sediments seen in the photo show the now barren delta, which experienced a “late flood event” that carried rocks and debris from the highlands of Mars to the banks of Mars.

“We have never seen such a well-preserved strata on Mars,” said Nicholas Mangold, lead author of Laboratoire de Planétologie et Géodynamique. “This is an important observation that allows us to see at once the existence of a lake and river delta in Jezero. A great benefit from a better understanding of hydrology months before arriving at the delta. You will get the road. “

According to a press release, the NASA team “has long planned to visit the Delta,” which leads to the Jezero Crater because it may contain fossils of ancient microorganisms.

The images collected provided scientists with information on where to find the best rock samples to find traces of life that may once existed on Mars. Scientists want to be able to bring it back to Earth for analysis with more powerful experimental equipment. So much ancient water evidence brings hope to scientists.

“We saw a clear layer in a cliff containing up to 5 feet of rock, which we knew there was no business there,” Mangold said.

Mangold and his team believe that the flash floods (which are tens of miles) that carried these rocks traveled at 4 to 20 miles per hour.

Sanjeev Gupta of Imperial College London, co-author of this treatise, found that the findings could provide valuable insights into why the entire planet was dry and what happened to the life of ancient microbes. There is. ”

NASA then plans to send a spacecraft to Mars to collect rock samples and return them to Earth.
