Since touchdown on Mars greater than a yr in the past, NASA’s Perseverance Rover has used its microphones to seize the sounds of the Red Planet, together with its harsh winds and the hum of Ingenuity slicing by the environment. And now these recordings have helped scientists uncover that sound travels in a different way on Mars than it does on Earth.

In a research printed on Friday within the journal Nature, researchers stated they decided the Red Planet’s skinny carbon dioxide environment causes sound to journey slower on Mars, with a sound’s pitch additional affecting its velocity. On Earth, sound usually travels at 767 miles per hour. But on Mars, scientists decided that low-pitched journey at roughly 537 miles per hour, whereas high-pitched ones transfer at about 559 miles per hour.
Were you to go to Mars, which means you’ll hear high-pitched sounds barely earlier. “On Earth, the sounds from an orchestra attain you on the similar velocity, whether or not they’re low or excessive. But think about on Mars, if you’re a bit of removed from the stage, there can be an enormous delay,” Sylvestre Maurice, the research’s lead creator, instructed France’s AFP information company.
Sounds additionally carry a shorter distance because of the planet’s skinny environment. On Earth, they drop off at about 213 ft, whereas on Mars sounds begin to falter after solely 13 ft. That’s one thing that will make it troublesome to have a dialog with somebody solely 16 ft away from you. If you need to hear how issues like birds and ocean waves would sound on Mars, NASA has put collectively recordings that give a way of simply how a lot a Martian-like environment would change our notion of the world.
