NASA scientists have created a Mars 'soundscape' using audio recorded by the Perseverance rover

NASA scientists have cut a year’s worth of audio recordings of persistence on Mars to five.jam Playlist of the best songs from the red planet (youYou can listen some here). His voice was very quiet Dan an offer A new way to explore the Martian environment. They already did Helps This confirms several theories about the way sound travels on the planet.

Audio from the rover was first published last year—No sound is very pleasing to the ear, probably due to electromagnetic interference. The latest sound is softer of that scream. a Sound analysis and what it can tell us about how sound propagates on Mars published Last month in nature.

Baptiste Scheid, Planetary Scientist at The Los Alamos National Laboratory told Gizmodo in a video call last year that sound heard on Mars would sound like it’s coming through walls, because Mars’ atmosphere is 1% as dense as it is. land. But Chadd was still amazed at how calm Mars was. He said praise in one of America’s vocal associations let go.

However, along with the science instruments, the rover is also equipped with two microphones, built with ready-to-use components, to record the first acoustic data on Mars.

One of the microphones on the Tenacity attaches to the rover’s frame and sits directly above one of its wheels. This microphone is wrapped on A net to protect it from Martian dust, which is stirred up by planetary winds and can be fatal to spacecraft, such as Therefore, opportunity explorers are not studied properly. Another microphone is mounted on the rover’s SuperCam, one of the main cameras in the machine that is placed in an arm above the rover’s frame.

As a result, the researchers found that the latter microphone picked up sounds of the wind blowing around the rover, while the former microphone picked up more sounds from the rover’s activities. The microphones successfully picked up the whine of the Ingenuity helicopter in flight, even when the rotorcraft was over 300 feet away.

In March, Chide’s team used the SuperCam microphone to Measuring the speed of sound on Mars. Recent research has used both microphones to characterize the acoustic environment of Mars, and has used sound sources near and far to show how a carbon dioxide-rich atmosphere affects it. The ability of sound to propagate.

Mars Much colder than Earth, thinner Atmosphere. NASA scientists expected sound to travel slower on Mars as a result, and rightly so. The researchers found that high-frequency sounds also travel faster than low-frequency sounds.

The sound on Mars will change throughout the year 687 days on Mars. During the Martian winter, carbon dioxide freezes in the planet’s polar regions, causing the loudness of the sound to fluctuate, according to the statement. Keep in touch. As long as persistence works as the name suggests, we should soon have a more diverse choice of Martian mixes.
