new Wanderer NASA captured images of the entire phase of entering the atmosphere, descent, and landing last Thursday. In addition to the excellent recordings, the new inhabitants of Mars also sent the first recorded audio and panoramic images on the red planet.
Perseverance, NASA mission robot Mars 2020, Has been sent The first video of landing On another planet in history. The video clip recorded the last Monday of February 18 (Thursday) and was released on Monday, recording the entire phase of the aircraft entering the atmosphere, descent and landing (EDL, its English abbreviation). Wanderer, From the deployment of the supersonic parachute until the wheels of “Percy” were already on the floor of Jezero Crater.
The video started playing approximately 230 seconds after the mission spacecraft entered the Martian atmosphere, and the time was approximately 20,100 kilometers per hour. At this time, after the parachute with a diameter of 21.5 meters travels the entire interplanetary path in the entire 46 x 66 cm small cylinder, it can be deployed in less than a second.
Since then, records have shown how the ship broke away from the ship. Insulation board He protected Perseverance during his space travel and entry into the Martian atmosphere.At this stage of descent, the ship is assisted by the following personnel Terrain-related navigation system Find a safe point on the surface to land.
Once the system found the best solution, Perseverance separated his landing parachute from the space capsule and began flying in the air. Jetpack This slows down further Wanderer On Mars.
After 80 seconds and 2130 meters, the mission camera captured the action of perseverance freed from him Jetpack Using a “crane” and multiple cables, the wheels touch the surface of Mars at a speed of 2.6 km/h. Once a landing occurs, the robot will cut the cable connecting it to the crane, activate its rocket, and safely drive away from Perseverance.

HiRISE camera, installed on the satellite Mars Reconnaissance Orbiter Scientists from NASA and the University of Arizona (MRO) took a surface photo showing the position of Perseverance on Martian soil and the different components of the EDL stage: parachute, ship hull, Jetpack And heat shield.
The first audio and panoramic image of Jezero crater
Another milestone for Percy is the record First audio clip From the red planet.Although the original idea was to get the sound of the entire EDL stage at the same time, the microphone is still connected to Wanderer Failed to record data during the entry to Mars.
However, another device has managed to obtain approximately 60 seconds of recorded audio on February 20, where it is possible to enjoy the martian breeze and the sound of persistent operations on the surface.
Finally, the persistent Navcam camera took a few photos, and these photos formed Panoramic picture Places near Jezero Crater Wanderer Looking for signs of life in the past, as well as collecting samples and testing technology, these technologies will serve the future manned missions to the Red Planet.
