Collision at Asteroid Dimorphos (APOD: 2025 Jul 28) Video Credit: ASI NASA, Johns Hopkins APL, DART, LICIACube, LUKE, IOP https://apod.nasa.gov/apod/ap250728.html Explanation: Why was this collision so strange? In 2022, to develop Earth-saving technology, NASA deliberately crashed the DART spacecraft into the asteroid moonlet Dimorphos. The hope was that this collision would alter the trajectory of Dimorphos around its parent asteroid Didymos and so demonstrate that similar collisions could, in

Just in case you missed yesterday's Double Asteroid Redirection Test (DART) impact, here is a sped-up version of the last five-and-a-half minutes of images from the spacecraft before it went boom. DART is a mission designed to test the kinetic impactor method of deflecting asteroids. Basically, we want to know if we can move asteroids on course for Earth by hitting them really, really hard. Yesterday's target was the asteroid moon Dimorphos. It orbits a larger asteroid named Didymos, which is vi
