A variety of shots will be taken on Mars for the 23-camera persistence. For example, seven of them must capture the entrance, landing and landing to the Martian atmosphere. But the devices also include a few microphones. If all goes according to plan, the historical audio recording of the arrival and landing on Mars will provide the sound of the rover, wind and other ambient sounds in the workplace.
However, JPL pointed out that on a neighboring planet, it is much different than on Earth. This is because the atmosphere on the surface of Mars contains only one percent of the density of the Earth and other compositions, which affects the radiation and propagation of sound. NASA At its site it gives the opportunity to hear some of the sounds known on earth – Like a bird singing in a serious city, like a bicycle bell or the waves of the sea – Compare what scientists think Mars looks like.
NASA has already sent two devices with microphones to Mars – a Mars Polar lander mission failed, and the Phoenix lander had a microphone on the landing camera, but it never turned on.
The Perseverance program primarily searches for signs of life on Mars. The tasks of the automated researcher include explaining the climate and geography of the planet and collecting samples of rocks and dust that may be taken to Earth at some point in the future. The purpose of the expedition is to pave the way for people to explore Mars.
A robot with a helicopter
To achieve these goals, the robotic researcher is equipped with a number of new tools and equipment. Using some of them, if perseverance proves successful in this work, it is also considered for human exploration to Mars. One such innovation, for example, the small robotic helicopter ingenuity, is the first helicopter to explore the vehicle’s surroundings in thin air, always just a few minutes.
