NASA’s Perseverance Rover helps scientists discover sound travels slower on Mars

Since landing on Mars more than a year ago, NASA’s Perseverance Rover has used its microphones to capture the sounds of the Red Planet, including its harsh winds and the hum of Ingenuity cutting through the atmosphere. And now those recordings have helped scientists discover that sound travels differently on Mars than it does on Earth.In a study published on Friday in the journal Nature, researchers said they determined the Red Planet’s thin carbon dioxide atmosphere causes sound to travel slower on Mars, with a sound’s pitch further affecting its speed. On Earth, sound typically travels at 767 miles per hour. But on Mars, scientists determined that low-pitched travel at approximately 537 miles per hour, while high-pitched ones move at about 559 miles per hour.Were you to visit Mars, that means you would hear high-pitched sounds slightly earlier. "On Earth, the sounds from an orchestra reach you at the same speed, whether they are low or high. But imagine on Mars, if you are a little far fro
