Mars rover sends back grinding, squealing sounds of driving

NASA’s newest Mars rover has sent back the first ever sounds of driving on the red planet, a grinding, clanking, banging affair that by Earth standards would be pretty worrisome. The noises made by Perseverance’s six metal wheels and suspension on the first test drive two weeks ago are part of a 16 minute raw audio feed released Wednesday by Jet Propulsion Laboratory in Pasadena, California.

Dave Gruel, an engineer on the rover team, said , if I heard these sounds driving my car, I’d pull over and call for a tow. But if you take a minute to consider what you’re hearing and where it was recorded, it makes perfect sense.

The driving audio contains a unexpected high pitched scratching noise informed by NASA.
