NASA this week shared sounds of Mars that the Perseverance rover managed to capture from the surface of the red planet, where it has been exploring and working on different science missions since February.
In this way, it is possible to perceive what gusts of Martian wind, sandstorms, and even the wheels and motors of the spacecar sound as it moves. “These sounds allow scientists and engineers experience the red planet in new ways“, assures the American space agency.
The five hours of audio collected by Perseverance in nearly a year of exploration have been made possible by two microphones, one located on the chassis of the vehicle and the other on the mast. It is worth noting that both audio devices are commercial models available to the public.
The sounds can be heard from minute 1:30.
The recordings are teaching scientists about the Mars “changes of atmosphere”, based on the fact that sound travels through air vibrations, explains NASA. The boom microphone is capable of recording the sounds made by the SuperCam laser instrument, and its position is “ideal” for monitoring “microturbulence (minimal changes in air)”.
Baptiste Chide, a planetary scientist who studies the data from the microphones, assures that these will be “an important asset for the future science of Mars and the solar system.” He further adds that Martian sounds have “strong bass vibrations”, unlike the terrestrial ones.
In this regard, NASA details that the microphones allow to investigate How sound travels on that planet and stresses that, because Earth and Mars have different atmospheres, the way sound is heard is affected. Martian is much less dense and therefore higher pitched sounds in particular are difficult to hear.
