Astronomers rejoiced as NASA's Double Asteroid Redirection Test (DART) impactor slammed into its pyramid-sized, rugby ball-shaped target 11 million kilometres (6.8 million miles) from Earth on Monday night.
Hubble images from 22 minutes, five hours and eight hours after impact show the expanding spray of matter from where DART hit.
The Hera mission, which is scheduled to launch in October 2024 and arrive at the asteroid in 2026, had expected to survey a crater around 10 metres (33 feet) in diameter.
