Of course, come on Tuesday We went there and explored it with rovers, satellites and telescopes. We have made tremendous progress in learning about our “brother” planet, but some things remain a mystery.
One of the pieces we put together in the mosaic to learn about the Red Planet is the sound they hear there. Our voice And sounds very familiar to us.
Scientists’ study
Our main tool for understanding what Mars’s noise is, again, is the NASA rover DiligenceSome microphones are also mounted on the board.
Determined by a team of international researchers who analyze the sounds captured by diligence The speed of sound in Mars. Baptiste Side of the National Laboratory in Los Alamos, USA, presented the results of this research at the 53rd Conference. Lunar and planetary science.
The Microphone Because of the diligence fitted, the rover allowed us to send the first sounds we heard from a planet other than our own – many of these sounds can be heard on the diligence rover’s webpage. In a new study, researchers analyze sounds and see if they can reveal anything useful.
To do this, Chide’s team of researchers used microphone data to measure the speed of sound on Mars. They did this by measuring the time it takes for sounds to be emitted Laser bursts Diligence led them back to the rover’s microphone. These laser beams were used to evaporate rocks for a more thorough examination.
It would be hard to talk about Mars
In this way, scientists discovered that sound travels to Mars 240 meters per second, 340 m / s on Earth. But they also found that on the red planet different frequencies travel at different speeds. The speed increases to about 10 meters per second over 400 beats.
That suggests innovation It can be hard to talk On Mars: Different parts of the speech placed on the board will reach the listener at different times and the conversations will be confusing and difficult to understand.
The words are then adjourned and come even in one volume Slightly less Compared to normal terrain: Mars’ atmosphere is about a hundred times less dense than terrestrial. This affects how sound waves travel from the source to the receiver, resulting in a smoother signal. On Mars, to hear the same amount of sound as on Earth, you have to be very close to its source.
Plays another important role Temperature Of the planet: sound travels at different speeds depending on heat or cold. By diligently measuring the speed of sound while diligently firing its laser, the researchers were able to calculate rapid changes in temperature. Sight said his research team plans to constantly monitor and analyze sounds coming from Mars during the winter months or to learn more about the fluctuations that occur on the planet during dust storms.
