In the movie "The Martian", the astronaut "Mark Whitney" lived a difficult days on Mars, steadfast with the presence of a few resources that helped him stay alive after his comrades believed that he died in a strong Martian storm they exposed to;Before they received the first sign of it stating that he is still alive.
The film reviewed the features of the dirt storm on the surface of Mars harsh;Where the winds released strength and noisy voices to collide the dust and stones with the equipment and the facility in which Whitney lived.
The following question is stopped here:
If human beings are able to adapt in another planetary atmosphere, they decide to migrate to live on the surface of Mars in effect, then its atmosphere began to disturb and expose to a strong sandstorm;Will the same voices make on the planet Earth, or as the film showed them?
actually;Mars is completely different from our planet;So it is natural that there are multiple factors that will cause the functioning of life naturally on Mars;Such as the different components of the atmosphere that the oxygen gas lacks, the difference in atmospheric pressure, heat, and of course the way of direct communication between humans.Speaking of human communication;One of the most important means of communication;It is the sound.

What is the sound, how does it move?
We may have long thought that the space is completely silent, but if we look at the content of the space;It contains cosmic gases between stars and galaxies, and the dust left by the stars after their death or which is sometimes used in the formation of new stars.
These gases and dust - particles - have the ability to carry sound waves in space, but all that we are humans are not qualified to hear them;Where the gas and dust particles that carry the sound waves are spread at a distance;Thus, sound waves are produced with a low frequency than the appropriate frequency of the human ear;So we cannot hear it.
And the interpretation of that;It is that the sound is transmitted in the form of molecules that collide and jump in the direction of the help of each other;Therefore, the sound loses its speed, except for the sounds that are transmitted near us.
On Mars
It is designed in a small size, with a length of about 5 cm, and its thickness reaches one cm, and weighs less than 50 grams.It is also designed to use a small amount of energy, less than 0.1 watts during the most active times.
The design includes many necessary electronics that work to capture and store the sound, where the rate of access to data is limited, while it takes 10 seconds to restore a period of 10 seconds for a period of time.
The device has an internal memory that will store sounds to transfer to the ground alongside other data that the vehicle picks up.The manufacture of the device cost about $ 50,000.
finally;Next year;Spacex is supposed to send missions to Mars with the help of NASA, and send inhabited missions between 2024-2025;So we are on a new date with another life on Mars in a way larger than how the sound is transmitted.
