The American space agency POT has released this Monday the first video of the Perseverance landing on Mars and also the first sounds recorded by the microphones installed in the space vehicle that descended at full speed last Thursday to land in the Jezero crater of the red planet.
The video, NASA experts point out at a press conference, evidences the “violent” Perseverance descent operation, that in seven minutes since the fine atmosphere of Mars reduced speed from 20,000 kilometers per hour to zero.
One of the video images shows the opening of the supersonic parachute after it detached from the capsule that transported the vehicle and also the fall of Perseverance producing a cloud of dust already close to the surface of Mars.
Of The videos they come off “thousands” of images that are already being analyzed by NASA scientists, who have already begun to classify the rocks they have seen, including light, perforated, dark and regolith.
Jezero Crater was chosen by NASA because it is believed to have been a lake into which a river flowed and therefore can be rich in fossil microorganisms.
During the press conference “the first sounds recorded on the surface of Mars” were also disclosed, thanks to incorporation into the “rover”, for the first time, from two microphones.
In the first segment you hear the vehicle descending and the loud noise of the wind, and in the second some wind, but mostly a silent Mars.
In addition to the new interpretations on the Martian surface, the images derived from the video, especially those of the landing, they will serve for its analysis during “years and years”. Of these dangerous landing maneuvers, Allen Chen, Perseverance’s entry, descent and landing leader, said that although it “behaved as expected”, they did observe some details that need to be analyzed and improved; one related to the parachute.
