NASA has released the first audio recordings and panoramic video from Mars – Technology


A new video from the rover Perseverance launched by NASA recorded the highlights during the last minutes of its landing on the Red Planet on February 18, and on that occasion, the microphone on the rover also recorded the first audio recording of sounds from Mars.

From the moment the parachute opened, the cameras covered the entire descent process, showing some of the more interesting rover rides to Mars Crater Lake.

The footage from the high-resolution cameras begins 11 kilometers above the surface, showing the opening of the most massive parachute ever sent outside our planet, and ends with the rover touching the surface of Mars.

NASA also published a panoramic photo on the mission’s official Twitter page, along with the caption: “Landing on Mars is a burst of tension, drama and noise. Then, when the dust clears: serenity and magnificence. “

The microphone attached to the rover did not collect useful data during the descent, but the device survived a very dynamic descent to the surface and on February 20 recorded sound from the Jezero crater.

In the tenth second of the one-minute recording, you can hear the “Martian wind”, as NASA called it, which can be heard for a few seconds, as well as the mechanical sounds of a rover moving on the surface.

More than 30 GB of information has already been collected from the rover, along with 23,000 images as the vehicle descended.

Matt Wallis, Perseverens’ deputy manager, revealed that he got the idea for a sophisticated camera system after he bought a sports camera and a case for his daughter, a gymnast.

He explained: “I don’t know about you, but I can’t make a reel back. But when she showed me the video – and I watched that camera roll up to the ceiling and the room turned upside down and somehow straightened, she got to her feet – for a moment I felt I had an insight into what it would be like to be able to make that reel. ” .

Wallis added: “It is unlikely at this point in my career that I will pilot a spacecraft to the surface of Mars. But when you see these pictures, I think you will feel what it might be like. “

“For those who are wondering what it looks like to land on Mars or why it’s so difficult or how cool it would be – there is no need to ask further,” said NASA Acting Administrator Steve Jurczik.

“‘Perseverance’ is just beginning its work and has already provided some of the most famous visual elements in the history of space exploration. It helps the extraordinary level of engineering and precision needed to build and fly vehicles to the Red Planet, ”said Steve Jurczik.

The rover of the American space agency NASA landed on Mars on February 18, after seven months of travel, several decades of work and billions of dollars spent, and on that occasion, the first photos from the ground of Mars were published.
