> 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.
