NASA has a little surprise for all the space enthusiasts out there.
NASA has released an audio track of the sounds picked up by the Perseverance Rover’s built-in microphone as it blasts through interplanetary space towards Mars. Perseverance Rover, which is the first spacecraft to be equipped with an audio device, aims to land in the Jezero Crater of Mars on February 18, 2021. NASA shared the 60-second audio file, collected during an in-flight camera check and microphone system, SoundCloud.

How did NASA capture sound in the vacuum of space?
The US space agency collected the file on October 19 after engineers on Earth turned on the microphone to check if the system is working properly. NASA said the buzz comes from the rover’s heat rejection fluid pump. Sound does not travel in the vacuum of space, but NASA managed to capture the hum as it traveled through the solid object as mechanical vibrations.

“Apologizing to the person who came up with the slogan for” Alien “, I guess you could say that no one in space could hear you scream, but they can hear your heat rejection fluid pump. The microphone we have included to hear how it is landing on Mars was actually able to pick up Perseverance’s thermal system operating in the vacuum of space through mechanical vibrations, ”said Dave Gruel, chief engineer for Mars 2020’s EDL Camera and Microphone subsystem.
