The Scary Sounds of Mars: NASA Makes Incredible Sound Picked Up Through Perseverance on the Red Planet!

NASA’s rover, Perseverance, has been recording the “terrifying sounds of Mars” since its arrival in February, including its wheels and Ingenuity helicopter hitting the surface.

Hearing sounds from the Red Planet is made possible by a pair of microphones on the rover that make it sound like you’re really standing there, says NASA.

The rover has been cruising through Jezero crater for eight months, searching for signs of ancient life, while also taking amazing pictures and recording sound.

Perseverance is the first spacecraft to record the sound of the Red Planet, in addition to allowing us to hear the sound of winds on another world, and provide information about the atmosphere.

Analysis of the Martian sounds revealed “strong bass vibrations”, say researchers from the Institute for Research in Astrophysics and Planets in Toulouse, France.

The audio recordings also helped NASA engineers monitor the engines, wheels, and general operation of the Perseverance and helicopter.

So far, nearly five hours of audio has been recorded by two microphones aboard the Perseverance spacecraft, according to NASA.

This includes Martian winds, rover wheels breaking over gravel, and the roar of engines as the Ingenuity helicopter moves through the air.

These sounds are allowing scientists and engineers to experience the Red Planet in new ways, according to Baptiste Chede, a planetary scientist from France.

The microphones in the rover were both commercially available devices. One is mounted on the side of the rover’s hull, and the second microphone is placed on the rover’s mast as a complement to the SuperCam laser instrument, which studies rocks and soil by striking it with a laser, then analyzes the resulting vapor with a camera.

Because the laser pulses up to hundreds of times per target, the chances of picking up the thunderbolts increase rapidly: the microphone has already recorded more than 25,000 laser shots.

These recordings teach scientists about changes in the planet’s atmosphere.

From its position on the Perseverance mast, the SuperCam is ideally located for observing ‘micro perturbations’ – tiny shifts in the air.

This complements the rover’s dedicated wind sensors, which are part of an atmospheric instrument suite called MEDA (Mars Environment Dynamics Analyzer).

MEDA sensors sample wind speed, pressure, and temperature one to two times per second for up to two hours at a time.

On the other hand, a SuperCam microphone can deliver similar information at a rate of 20,000 times per second over the course of several minutes.

The microphone also allows research on how sound propagates on Mars.

Because the planet’s atmosphere is much less dense than Earth’s, scientists realized that especially high-pitched sounds would be hard to hear.
