Perseverance makes an exciting discovery during its mission to Mars. Researchers are talking about a “key note” for the NASA rover.

CAssel/Pasadena – NASA’s “Perseverance” rover faces major missions in Mars*. Among other things, he must search for signs of early microbial life on the Red Planet and research the geology and past climate of Mars. The rover has already answered an important question with the first images it has sent back to Earth, as NASA*now reports. Recordings and accompanying study have been published in science magazine.

“This is the main observation that assures us once and for all that there was a lake and river delta in Jezero crater,” said scientist Nicholas Mangold, the study’s lead author, in a message from NASA. Today, Jezero crater, where Perseverance landed in February 2021, is completely dry. But once there was water there, experts deduced from the Martian rover’s recordings. So Jezero crater 3.7 billion years ago was a lake fed by a small river.

The recordings also show experts that there must have been heavy flooding in the lake. According to researchers who worked with Mangold on their study, these floods carried large stones for kilometers along the river and deposited them in the lake where they are still found today.

It is no coincidence that “perseverance” hits the bull’s-eye shortly after its arrival. The landing site at Jezero crater was chosen by NASA experts on suspicion that water once flowed there. Recordings from Mars orbiters previously showed that Jezero crater looks like a dry lake* Connected to the river delta.

Mission to Mars: Discovery of NASA’s Rover Was No Coincidence

“The rover has solved one of the biggest mysteries without going anywhere,” says planetary scientist Benjamin Weiss. “Until we got there, the question was always: Was the crater ever a lake?”

Mars experts believe that water on the surface of the Red Planet once existed, but it dried up about 3.5 billion years ago. At that time, according to the current state of research, Mars lost its magnetic field and gradually lost its atmosphere. Assume another theory Mars was too small to hold water permanently*.

This is what Jezero crater looks like on Mars today. NASA’s “Perseverance” spacecraft has landed in the dry lake.

Meanwhile, the Perseverance rover has covered about 2.6 kilometers into Jezero crater, and if all goes according to plan, you’ll also see the rocks it picked up from a distance to solve the mystery of the lake up close. The rover is scheduled to head to the former river delta to take soil samples there. Experts believe that sediment from the former lake may contain traces of past life in the water. Therefore, the “perseverance” should also collect such samples. “Now we have the opportunity to look for fossils,” explains Tanya Bosak of the Massachusetts Institute of Technology.

Soil samples collected by Perseverance will be stored by the rover on Mars, and a future mission will return samples from Mars to Earth, where they can be directly examined by scientists. “It will take some time to get the stones in which we hope to find traces of life. It is a marathon with great potential,” Boussac continued.

NASA’s Mars rover: “Perseverance”: soil samples to be sent to Earth

Until then, however, the research must rely on “perseverance” and NASA’s older rover Curiosity, which is conducting research in a different region on Mars. “A better understanding of Jezero crater is key to understanding the changing hydrology in the area,” perseverance scientist Sanjeev Gupta said in a NASA statement. “This could give valuable information on why the entire planet is drying up.”

Weiss also has another hope: It is possible that we will find the time in the rock when the crater “passed from a habitable Earth-like environment to this devastated wasteland,” he explains. These beds of ruins can serve as recordings of this transition. We’ve never seen this before elsewhere on Mars. (tab) *the father is a show of IPPEN.MEDIA.
