This illustration of NASA's Perseverance Mars rover indicates the placement of the spacecraft's two microphones. The microphone on the mast is part of the SuperCam science instrument. The microphone on the side of the rover was intended to capture the sounds of entry, descent, and landing for public engagement. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect 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 approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. https://photojournal.jpl.nasa.gov/catalog/PIA24931

One of multiple microphone stations used in the CarpetDIEM flight series, which gave researchers valuable lessons learned in preparations to deploy a similar array for the quiet supersonic X-59. Prior to community overflights, X-59 will undergo an acoustic validation phase, during which NASA will deploy the array of specially-configured microphones to measure the X-59’s thumps, in order to verify that they are as quiet as predicted.

NASA's Mars 2020 Perseverance rover is equipped with two microphones that, if all goes as planned, will capture the sounds during entry, descent, and landing, and sounds on the Martian surface — from listening to the gusts of Mars' winds, to the "zap" of SuperCam's laser. This image depicts microphones under consideration the mission being tested at NASA's Jet Propulsion Laboratory in 2017. The microphones were placed inside a chamber with a playback speaker to record sounds within a simulated Martian environment. https://photojournal.jpl.nasa.gov/catalog/PIA24166

Juliet Page, a physical scientist with the Volpe National Transportation Systems Center, calibrates a microphone station during the CarpetDIEM flight series. The array featured high-fidelity microphones arranged in several configurations, giving researchers the ability to obtain accurate sound data and assess the loudness of the sonic booms, just as they will measure the quiet sonic thumps from the X-59.

Components are visible on the port side of the Perseverance rover in this close-up image taken on Nov. 16, 2019, in High Bay 1 of the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory in Southern California. At center of the image, attached to the side of the rover, is a black cable bracket (with gold cabling running through it). Attached to the top of this black bracket — and gray in color — is the Entry Descent and Landing (EDL) microphone.
