NASA publishes audio of the “rover” traveling to Mars



NASA has released an audio of the Captured 60 seconds on October 19 by one of the reconnaissance vehicle’s microphones Persistence, which is currently on an interplanetary flight bound for Mars.

“Interplanetary Sounds of the ‘Rover’ Perseverance” it can be heard on SoundCloud picking up the subtle sounds of the rover’s own mechanisms.

Sound waves they do not propagate in open space, but they move well on solid objectsThat’s why NASA needs microphones to monitor the rover’s machines.

Normally, the “rover” remains inactive and most equipment is off, and is only activated during verifications, as on this occasion.

Technology to have a record of Mars

The vehicle has two microphones, one installed in the SuperCam camera and another called EDL that is designed to handle record the process of entering the atmosphere, descent and landing device, scheduled for the start of the 2021.

Dave Gruel, Mars 2020 EDL Microphone and Camera Subsystem Principal Engineer Explained:

“The microphone we added to listen to what it’s like to land on Mars was able to capture the Perseverance thermal system operating in the vacuum of space through mechanical vibrations”

And the engineer pointed out that “getting noise from the landing is a good thing, no need. If this does not happen, it will in the least prevent the “rover” mission in the crater Jezero. Even if only part of the landing sequence were captured on audio, it would be great

NASA’s rover, launched last July, will reach the surface of Mars February 18, 2021, especially in the Jezero crater, an ancient lake with a diameter of 45 kilometers.

The mission of the new reconnaissance vehicle will consist of look for rocks that contain possible signs of ancient microbial life. At the end of October, the space agency reported that Persistence had completed half of its flight going to Red planet.
