Summary (IA Generated)
The Mars Perseverance rover, the first robot to record Martian sounds with a real microphone, has already picked up some eerie, extraterrestrial recordings.
The sounds, available below, include the rover’s metallic wheels rumbling over the desert ground, a laser zapping a rock 30 times, and the blowing Martian wind.
‘But when you realize you’re listening to sounds on another planet, of our own machine moving on the surface, and a laser vaporing a little bit of rock, suddenly these become profound and awe-inspiring.
5-minute-long Martian day), Perseverance recorded 16 minutes of the rover driving over the rocky Mars‘ ground.
You can hear pings, scrapes, and thuds as the six metal wheels roll over the hard surface.
Perseverance zapped a Martian rock 30 times with a laser.
They sound like snaps or cracks.
‘These sounds are exactly as you would hear them with your own ears if you were standing on the surface of Mars,’ Naomi Murdoch, a rover engineer and researcher at ISAE-SUPAERO (France‘s Higher Institute of Aeronautics and Space), said at a press conference on March 10.
Why zap a rock with a laser?.
Perseverance’s , which sits atop the robot’s mast like a crow’s nest on a ship, is equipped with the laser.
What’s more, NASA planetary scientists can also listen to zapping sounds on different surfaces, which reveals more information about the rocks, like their hardness.
The first sounds recorded on Mars were the wind.
At about six seconds into the short clip, you hear a wind gust on Mars, recorded on Feb.
Different rover sounds, like the drill and the rover zapping different rocks.
‘One of my dream sounds would be hearing a dust devil,’ said Betts.
Perhaps future missions — to other wild worlds in our solar system like the moons Titan or Europa — will one day beam back extraterrestrial sounds, too.
