A few days, NASA's Mars rover Perseverance touched down on Mars after a six month journey to get there. Perseverance has a busy schedule on Mars with a number of firsts planned. And one of those firsts just happened: Perseverance recorded an audio clip of Mars. This is the first time ever that humans have heard the sound of another planet. Just take a second to let that sink in. Then listen to the sound of Mars in the video below (underneath the first full color photo Perseverance took). Enjoy, Earthlings.
