Strange behavior on Mars, NASA released samples

NASA has released a study about the sound on Mars. NASA’s Perseverance rover has collected some samples of sound on Mars. These conclude that sound behaves differently on Mars. The study found that on the red planet Mars, sound moves at a slower rate than on Earth. It also behaves in a somewhat awkward way. Due to this, in the future, when humans make arrangements to settle here, there may be a problem in setting up the communication platform. The speed of sound also depends on the density of the atmosphere. The atmosphere of Mars is very thin, so the sound wave moves at a slow speed there. 

Sound travels on Earth at a speed of 343 meters per second. In some studies, it has been found that in more dense medium such as water, they can move at the rate of 1480 meters per second. Hence they accelerate in more dense medium and slow down in less dense medium. The atmosphere of Mars is up to 100 times thinner than that of Earth. It is composed mostly of carbon dioxide.

This study shows that different types of sound behave differently on Mars. Low-pitch sound travels here at a rate of 240 meters per second and high-pitched sound at a rate of 250 meters per second. NASA scientists say that such a process has never been experienced before. The scientists have published their discoveries in the journal Nature.  

Study co-author Baptiste Chide said, “Mars is surrounded by silence because the pressure of its atmosphere is very low. But its pressure varies according to the seasons. This means that the coming autumn season on Mars is more Noise can be heard.”  

The Perseverance rover and its associated Ingenuity helicopter were launched in July 2020 and landed on Mars in February next year. They are looking for signs of old life on this red planet.
