Another First: Perseverance Captures the Sounds of Driving on Mars
NASA’s latest rover recorded audio of itself crunching about the surface of the Crimson Planet, incorporating a total new dimension to Mars exploration.
As the Perseverance rover commenced to make tracks on the surface of Mars, a delicate microphone it carries scored a first: the bangs, pings, and rattles of the robot’s 6 wheels as they rolled about Martian terrain.
“A large amount of individuals, when they see the images, really do not recognize that the wheels are steel,” explained Vandi Verma, a senior engineer and rover driver at NASA’s Jet Propulsion Laboratory in Southern California. “When you’re driving with these wheels on rocks, it is essentially incredibly noisy.”

A lot more than 16 minutes of appears from Perseverance’s 90-foot (27.3-meter) push on March 7 ended up captured by Perseverance’s entry, descent, and landing (EDL) microphone, which continues to be operational on the rover following its historic touchdown on Feb. 18. The off-the-shelf microphone was added to the rover to help acquire the public alongside for the experience in the course of touchdown, but mission associates have been eager to listen to the appears from the surface, far too.
“If I listened to these appears driving my auto, I’d pull about and phone for a tow,” explained Dave Gruel, lead engineer for Mars 2020’s EDL Camera and Microphone subsystem. “But if you acquire a minute to consider what you’re hearing and where by it was recorded, it would make great feeling.”
Two versions of the audio clip of the similar push ended up launched to the public on March 17. The first edition options about 16 minutes of uncooked, unfiltered appears of the rover traveling in Jezero Crater. In it, the sounds generated by the conversation of Perseverance’s mobility system (its wheels and suspension) with the surface can be listened to, alongside with a high-pitched scratching sounds. Perseverance’s engineering staff proceeds to examine the resource of the scratching sounds, which may perhaps possibly be electromagnetic interference from one particular of the rover’s electronics containers or interactions between the mobility system and the Martian surface. The EDL microphone was not intended for surface functions and experienced limited tests in this configuration prior to start.
This first audio of a push across the Martian surface joins a expanding playlist of Mars appears beamed back again to Earth from Perseverance. A second microphone, part of the rover’s SuperCam instrument, beforehand picked up the sighing of Martian wind and the quick ticking sound of the instrument’s laser zapping rocks to expose specifics of their composition and composition. Such details will help researchers as they search Jezero Crater for indicators of historical microscopic lifetime, taking samples of rock and sediment to be returned to Earth by long run missions.
The SuperCam appears ended up part of a sequence of methods checks the rover has long gone by way of, ranging from the unstowing of Perseverance’s significant robotic arm to making its first temperature observations using the Mars Environmental Dynamics Analyzer.
The rover has also been browsing for a suited airfield for the Ingenuity Mars Helicopter to attempt its first flight exams. Now that the suitable place has been discovered, the Perseverance and Ingenuity teams are making plans for the rover to deploy the helicopter, which will have 30 Martian times, or sols (31 Earth times), to entire up to 5 examination flights.
And then the hunt for historical lifetime will begin in earnest, with Perseverance discovering terrain as soon as believed to be coated with h2o. Amongst the rover’s 19 cameras and its two microphones, the encounter will be packed with sights and appears. For Verma, who has assisted “drive” NASA’s previous 4 Mars rovers, scheduling their routes and transmitting directions so they can acquire a day’s push across uncharted terrain, the audio is much more than just interesting.
“The variants between Earth and Mars – we have a experience for that visually,” she explained. “But sound is a total unique dimension: to see the variances between Earth and Mars, and encounter that environment much more intently.”
A lot more About the Mission
A vital objective for Perseverance’s mission on Mars is astrobiology, like the search for indicators of historical microbial lifetime. The rover will characterize the planet’s geology and previous climate, pave the way for human exploration of the Crimson Planet, and be the first mission to gather and cache Martian rock and regolith (broken rock and dust).
Subsequent NASA missions, in cooperation with ESA (European Area Agency), would deliver spacecraft to Mars to gather these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration strategy, which includes Artemis missions to the Moon that will help get ready for human exploration of the Crimson Planet.
JPL, which is managed for NASA by Caltech in Pasadena, California, designed and manages functions of the Perseverance rover.
