You can see the rover landing on Mars for the first time. And it’s epic on many levels.
Humans have dropped machines on Mars since the 1970s. A lander that parachuted onto the surface of the water, a rover that was destroyed during the landing, and then a rover that survived the landing in a huge bouncing airbag cushion. A powerful sky crane is now lowering the NASA rover to the surface. But all the while, all these epic successes and failures have happened invisible in another world. It changed with patience.
NASA has equipped the Perseverance Rover and its landing vehicle, which arrived on Red Planet on February 18, with a collection of high-quality high-speed video cameras to capture the “7-minute horror.” The surface of Mars. The camera was set up to provide viewers with the last two chapters of a truck-like machine rush from the sun’s orbit into the soil of Mars, the front row seats of the parachute and sky crane.
So Live Science previously reportedQuietly placing a 10-foot (3.1-meter), 2,260-pound (1,025-kilogram) nuclear robot within a narrow target on another planet’s dangerously rough surface requires some clever maneuvers. ..

The video shows that the Rover lander can jump out of the heat shield and “see” the ground during landing, timing the parachute deployment. A metal disc falls, revealing a long fall separating the $ 2.7 billion nuclear rover from the ground. Another camera shows the parachute unfolding. This is a sheet of cloth intended to slow down the descent from 940 mph (1,512 km / h) to 190 mph (306 km / h) in 2 minutes. The lander then moves away from the parachute, where the robot pilot tackled the most difficult task. Identify and maneuver a safe landing site. Finally, the Sky Crane floats 65 feet above the surface of Mars, causing a sandstorm, dropping a slow-swaying rover with a long cable to the ground and then flying away.
No video was available to NASA during the fully robot-controlled landing. (Obtaining data from Mars takes time and the uplink bandwidth is much shorter than the streaming speed, but NASA was able to carry 30 gigabytes of media across the interplanetary space in a few days. However, Perseverance uploaded the material over the weekend in time for NASA. It will be released on Monday (February 22nd).
NASA said the video would provide important data for future missions, confirming that almost every stage of the descent went as planned. Closest to the problem seen in the video: A clearly harmless loose spring behind the heat shield. Visible when the protective shroud leaves the lander.
NASA also released the first sound recorded with a microphone on Mars.
