This image of the Dimorphos was taken by Hubble about four months after the asteroid was hit by the DART mission (Double Asteroid Redirection Test). Hubble’s sensitivity reveals dozens of boulders knocked loose by the impact. They are among the faintest objects Hubble has ever photographed in the Solar System. Hubble’s photometry suggests the boulders range from 3 to 22 feet across. They are drifting away from the asteroid at a roughly a half-mile per hour.
