The Perseverance Mars rover took the first Mars photo after the signal was interrupted. The scenery is amazing
The Perseverance rover landed on Mars and took the first photo!
Because Mars has been obscured by the sun recently, this car-sized machine and the rest of NASA's Mars probe have to suspend operations.
On October 22, 2021, NASA's Perseverance Mars rover used one of its navigation cameras to capture the scene around it on the ground of Jezero Crater. Three days later, the mission team posted the photo on Twitter . (Image source: Twitter NASA/JPL-Caltech/ASU)
After experiencing the first communication interruption caused by the "solar system connection", the United States Space Agency's (NASA) Perseverance Mars rover finally came back online and continues to travel on Mars. carry out work on. But what’s even more exciting is that as soon as Perseverance went online, it sent back to Earth the first photo of Mars it took.
In the past two weeks, because Mars, the Earth and the sun are exactly in line, Mars will be blocked by the sun when viewed from the earth, and Perseverance and other detectors on Mars can only suspend operations. Fire, earth, and the sun are connected in a line, which is called the "solar system link". When Mars and the earth move to both sides of the sun, the sun in the middle will affect the signal transmission between the earth and Mars, so During this period, it was difficult for NASA or other space centers to send commands to the probe on Mars.

However, now that Mars has "run" out from behind the sun again, NASA's Jet Propulsion Laboratory in Southern California has also been able to restore communications and "return control" of Perseverance. As soon as Perseverance was "awakened", it quickly conducted an exploration of the Jezero Crater. The crater is about 28 miles (45 kilometers) wide and once hosted a lake and river delta billions of years ago.

"I have started working online and am now parked next to these two beautiful rocks. I am currently doing some imaging, climate research, and chemical experiments, and I will update the software by the way." The mission team released on Monday (October 25) This passage was posted on Perseverance’s official Twitter account.
This post also contains two photos of the terrain that Perseverance has recently passed through. Many photos have been taken since it returned to work, and you can enjoy them on the official website.
Perseverance landed on February 18. Its main mission is to search for signs of ancient life on Mars and collect samples to bring back to Earth in the future. At present, Perseverance has collected and stored two tubes of original Martian material samples, moving towards the goal of recovering interstellar samples for the first time.
Landed with Perseverance and a small helicopter named "Ingenuity ". Its role is to verify that aerial exploration on Mars is feasible. Ingenuity has also resumed work and completed its 14th Mars flight on Sunday (October 24).

After conducting its first five technology demonstration flights, Ingenuity has been switched to an extended mission to demonstrate the search potential of Mars rotorcraft. Recently, the helicopter , which weighs about 4 pounds (1.8 kilograms), has been scouting the Martian terrain for Perseverance and has so far advanced 1.66 miles (2.67 kilometers) on the Jezero Crater floor.
Perseverance, nicknamed "Posey", is a Mars rover about the size of a car. It is designed to explore the Jezero Crater on Mars. This is also the mission plan of NASA's "Mars 2020" part of. It was manufactured by the US Jet Propulsion Laboratory and launched at 11:50 on July 30, 2020. It was confirmed to have successfully landed on Mars at 20:55 on February 18, 2021. As of March 25, 2022, Perseverance has been active on Mars for 389 Mars days (400 Earth days) since landing on Mars.After Perseverance landed, NASA named its landing site the Octavia E. Butler Landing Site.

The design of Perseverance is similar to the previous generation of Mars rover "Curiosity", and has been upgraded and improved on its basis. It is equipped with 7 sets of scientific instruments, 19 cameras and 2 microphones. At the same time, it also carried a small helicopter "Ingenuity" to Mars, which is an experimental vehicle and a technology demonstration. Ingenuity conducted its first flight on Mars on April 19, 2021. So far, it has completed 19 flights.
The mission goals of Perseverance include searching for ancient environments that supported life on Mars and looking for evidence of the past existence of microorganisms; collecting rock and soil samples stored on the surface of Mars; and testing the oxygen production in the Martian atmosphere to prepare for future manned missions.
