NASA’s Center for Near Earth Object Studies keeps an eye on the sky, surveying more than 26,000 asteroids and a much smaller number of comets that pass near Earth. Near Earth Asteroids, or NEAs, also include more than 2,000 potentially dangerous specimen, of which 158 have a diameter of more than one kilometer, making them 2.5 times as tall as the Empire State Building.

On April 30, 2021, NASA’s Perseverance rover made history as the first spacecraft to record sounds from another spacecraft on another planet. During Ingenuity’s fourth flight, a microphone included with the SuperCam instrument aboard Perseverance captured the humming sound of the blades and the din of wind.
