But the recording was lost due to malfunction in a system that was programmed to digitize the audio for storage on the rover\u2019s computer.<\/p>\n<p>Nevertheless, the microphone is still functional, and NASA released an audio clip a few days after landing of a wind gust on the surface of Mars. It was the first recording of natural sound from another planet.<\/p>\n<p>Now NASA has released another audio recording captured as the rover drove across Martian soil.<\/p>\n<p>The rover\u2019s aluminum wheels are about 20.7 inches (52.5 centimeters) in diameter. The six wheels have cleats for traction and titanium spokes for \u201cspringy support,\u201d NASA says.<\/p>\n<p>\u201cA lot of people, when they see the images, don\u2019t appreciate that the wheels are metal,\u201d said Vandi Verma, a senior engineer and rover driver at NASA\u2019s Jet Propulsion Laboratory in Southern California. \u201cWhen you\u2019re driving with these wheels on rocks, it\u2019s actually very noisy.\u201d<\/p>\n<p>NASA released two versions of the audio \u2014 one 90-second file edited and processed to filter out background noise, and another 16-minute clip with raw, unfiltered sound. The short and long versions are posted below.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/w.soundcloud.com\/player\/?url=https%3A\/\/api.soundcloud.com\/tracks\/1009995931&amp;color=%23ff5500&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false&amp;show_teaser=true&amp;visual=true\" width=\"100%\" height=\"300\" frameborder=\"no\" scrolling=\"no\"><\/iframe><\/p>\n<p>NASA \u00b7 Sounds of Perseverance Mars Rover Driving \u2013 Sol 16 (90-second highlights)<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/w.soundcloud.com\/player\/?url=https%3A\/\/api.soundcloud.com\/tracks\/1009995607&amp;color=%23ff5500&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false&amp;show_teaser=true&amp;visual=true\" width=\"100%\" height=\"300\" frameborder=\"no\" scrolling=\"no\"><\/iframe><\/p>\n<p>NASA \u00b7 Sounds of Perseverance Mars Rover Driving \u2013 Sol 16 (16 minutes)<\/p>\n<p>\u201cIf I heard these sounds driving my car, I\u2019d pull over and call for a tow,\u201d said Dave Gruel, lead engineer for Mars 2020\u2019s EDL Camera and Microphone subsystem. \u201cBut if you take a minute to consider what you\u2019re hearing and where it was recorded, it makes perfect sense.\u201d<\/p>\n<p>Perseverance recorded the sounds during a 90-foot (27.3-meter) drive March 7, according to NASA. The rover\u2019s top speed is a little less than 0.1 mph, or about 152 meters per hour.<\/p>\n<p>The longer, raw audio clip includes a high-pitched scratching noise. The origin of the sound remains a mystery.<\/p>\n<p>\u201cPerseverance\u2019s engineering team continues to evaluate the source of the scratching noise, which may either be electromagnetic interference from one of the rover\u2019s electronics boxes or interactions between the mobility system and the Martian surface,\u201d NASA said in a statement. \u201cThe EDL microphone was not intended for surface operations and had limited testing in this configuration before launch.\u201d<\/p>\n<p>Sounds travel much differently on Mars than on Earth. The Martian atmosphere is less than 1 percent the thickness of Earth\u2019s atmosphere at sea level, and is primarily made up of carbon dioxide, not nitrogen and oxygen.<\/p>\n<p>Last week, scientists working on the rover\u2019s SuperCam instrument released an audio recording from a different microphone on the Perseverance rover.<\/p>\n<p>The SuperCam instrument, developed in partnership between U.S. and French scientists, is designed to measure the composition of rocks using cameras, a laser, spectrometers, and a microphone.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/w.soundcloud.com\/player\/?url=https%3A\/\/api.soundcloud.com\/tracks\/1004116528&amp;color=%23ff5500&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false&amp;show_teaser=true&amp;visual=true\" width=\"100%\" height=\"300\" frameborder=\"no\" scrolling=\"no\"><\/iframe><\/p>\n<p>NASA \u00b7 First Acoustic Recording of Laser Shots on Mars<\/p>\n<p>The microphone on the SuperCam instrument is an aid for scientists to understand the physical properties of Martian rocks and soils.<\/p>\n<p>\u201cThis is a very important technique in order to determine the hardness of samples,\u201d said Naomi Murdoch, a SuperCam team member from the&nbsp;Institut Sup\u00e9rieur de l\u2019 A\u00e9ronautique et de l\u2019Espace in Toulouse, France.<\/p>\n<p>One of the primary goals of the $2.7 billion Perseverance rover mission is to gather, seal, and cache samples on Mars for retrieval by a robotic return mission in the late 2020s.&nbsp;Data from SuperCam can help identify organic molecules \u2014 the building blocks of life \u2014 and help ground teams determine which rocks Perseverance should drill and sample for return to Earth.<\/p>\n<p>Ground teams hope to use Perseverance\u2019s microphones in the future to record the sound of the rover\u2019s&nbsp;drill coring out the rock specimens.<\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>NASA\u2019s Mars Perseverance rover acquired this image using its onboard left Navigation Camera (Navcam) on March 7, the same day the rover\u2019s microphone recorded the sounds of driving.
