NASA's Perseverance Rover helps scientists discover slower sonic flights on Mars

or On Mars more than a year ago, NASA’s Perseverance Rover used its microphones to pick up sounds from the Red Planet, including its own. buzz of creativity . Now these recordings have helped scientists This sound propagates differently on Mars than on Earth.

In a study published Friday in the journal, Researchers said they found that the red planet’s thin carbon dioxide atmosphere slows the propagation of sound on Mars, while increasing the effect of sound on its speed. On Earth, sound typically travels at 767 miles per hour. But on Mars, scientists have determined that extreme movements are about 537 miles per hour, while sharp ones move around 559 miles per hour.

If you visit Mars, this means that you will hear high-pitched voices a little earlier. “On Earth, the sounds of an orchestra reach you at the same speed, soft or loud. But imagine on Mars, if you were a little further from the scene, there would be a significant delay,” lead author Sylvester Morris told France. .

Sounds also carry a shorter distance due to the planet’s weak atmosphere. On Earth, they drop about 213 feet, while on Mars, the sounds start to fade after only 13 feet. This is something that would make it difficult to have a conversation with someone who is only 16 feet away from you. If you want to know what things like birds and ocean waves would look like on Mars, NASA put them together Which gives an idea of ​​how the Martian-like atmosphere affects our perception of the world.
