MOSCOW, 11 Mar – RIA Novosti. The Perseverance rover has recorded the sound of its laser on the Red Planet for the first time, according to a NASA press release.
Earlier it was reported that the rover made the first test drive around the planet.
Did you know? Some sounds that we're used to on Earth, like whistles, bells or bird songs, would be almost inaudible on Mars.

The first recordings of the SuperCam instrument installed on the rover have arrived on Earth. “The data from the instrument arrived at the French space agency's operations center in Toulouse and includes the first audio recordings of laser sound on another planet,” the press release said.
The mission released three audio files, the first of which was recorded just 18 hours after landing. There is a lot of wind on the recordings, especially on the second 20-second recording, which was made on the fourth Martian day (February 22). The third file, recorded on 12 Martian days (March 2), shows the clicks of a laser aimed at a rock at a distance of about 3 meters. Some laser hits are slightly louder, giving information about the physical structure of different targets, such as relative hardness.
NASA's newest rover, Perseverance, launched from Earth last July and successfully landed on Mars in February. The device has already transmitted to Earth not only images of the Red Planet, but also a video recorded during its landing.
