NASA has released an official release inwhich presented the first high-quality video of the landing of the Perseverance rover on the Red Planet to the world public. In addition, an audio recording has been made public, allowing earthlings to "hear" sounds from Mars for the first time. The landing process at NASA was called the most intense phase of the mission. The landing control took place completely under the control of the onboard artificial intelligence, which chose a suitable, level landing site. The entire process of descent and landing of Perseverance was filmed from several angles, cameras located on different modules of the mission.
Landing 260 seconds after enteringthe landing complex into the planet's atmosphere at a speed of 20 100 km / h. The first footage of the landing was filmed at an altitude of 11 km above the surface and shows the view of a landing parachute expanding from a capsule-cylinder (46 by 66 cm) at supersonic speed. In less than a second, the spacecraft's parachute opens into a 21.5-meter dome.
Then the video shows the shooting of the heatscreen that protected the rover from "scorching temperatures" when braking in the atmosphere. The camera under the "belly of the rover" begins to film the surface of Mars. In the video, you can see that the picture swings smoothly, as the rover swings and slows down under a huge parachute.
Then the braking system comes into play andperforming a maneuver before landing, carried out with the help of a sky crane - a kind of "jetpack", which allowed the rover to hover over the landing point and smoothly "land" on the surface. The cameras filmed as eight crane braking motors raised a dust cloud on the surface, blowing off the regolith that had been lying motionless on Mars for millions of years.
The final landing frames show howPerseverance's aluminum wheels hit the surface at 1.61 mph (2.6 km / h), and then pyrotechnic blades cut the cables connecting it to the launch module still hovering above the surface. After disconnection, the landing stage flies to the side, so as not to damage the rover during landing.
Using a microphone mounted onPerseverance, an audio recording was received, on which, against the background of the working mechanisms of the rover, you can hear the sounds of the Martian breeze. It is noteworthy that the microphone, which survived the journey of almost half a billion kilometers and the passage through the atmosphere of Mars, is a serial commercial sample.
NASA also published on itsresources, over 4,000 unprocessed RAW images, captured by numerous Perseverance cameras, are freely available. In total, the rover has 23 cameras. The main stereoscopic device Mastcam-Z (Z stands for "magnification"), provides a three-dimensional image when the vehicle moves over the surface and serves as an analogue of the "eyes" for the artificial intelligence of the rover controlling the Martian.
Testing of allonboard Perseverance systems. The two-kilogram helicopter, placed in the lower part of the rover and designed to study the fundamental possibility of helicopter flight in the rarefied atmosphere of the planet, also began to recharge. Then Perseverance will begin its main mission - the search for biological life in the Jezero crater and in the bed of an ancient river that flowed into the lake that was in the crater bowl millions of years ago.
