Sounds Travels Slower in Mars

Researchers are monitoring the recordings that are captured on microphones by NASA’s Perseverance rover. The rover has found that the Sounds Travels slower on Mars. The results of the study were published in Nature.

The research team monitored the recording that was recorded in 2021. The researchers were able to compare Martian sounds to Earth noises by using recorded sounds from the rover that was used to break rocks and flying sounds from the Ingenuity helicopter. They discovered that Sounds Travels on Mars at a speed of 100 metres per second slower than on Earth.

The news release also said that the researchers realised that there are two speeds of sound in Mars. This would be difficult for two people standing only five meters apart to have a conversation. The extraordinarily low atmospheric surface pressure creates a unique acoustic environment. The pressure on Mars is 170 times lower than on Earth.

A high-pitched voice travels 213 feet on Earth but only 26 feet on Mars.  While human ears can detect sounds on Mars, they are quite faint. Researchers declared the first recordings to be the first time sounds from another planet had ever been caught when they were made last year. The recordings, according to Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate, are “the closest you can get to landing on Mars without putting on a pressure suit.” It found that the red planet faced flash floods that carved the landscape into the rocky wasteland we see today.
