NASA plans to 'eavesdrop' on Mars

NASA scientists are working hard to find and record possible sounds on Mars.

Scientists from the US Aerospace Agency (NASA) will install recording microphones into Mars Rover's self-propelled self-propelled Mars Rover .

So far people have not known anything about the sounds that appear on the Red Planet. People hope to change this reality, when Mars Rover is launched on Mars in 2020.

So far, there have been many plans to install sound recorders on self-propelled vehicles posted on Mars but all failed, in part because of financial reasons. NASA used to install a microphone on the Phoenix Lander self-propelled car, but the device lost contact.

The plan is also not easy to implement when the atmospheric pressure on Mars is between 6 and 10 Torr units (atmospheric pressure at sea level on Earth is 735.5 units). This means that the sound will need to be much larger, the human ears or the receiver of the microphone can be recorded. It also means that the microphone will have to be very sensitive to record the sound.

Now scientists are considering the ability to use the microphone of Knowles, which has been fitted to the previous generation self-propelled cars, the Mars Polar Lander and Phoenix.

In addition to recording, the microphone will have the task of supporting collecting statistics on wind speed and studying dust at a distance close to self-propelled vehicles.
