South Korea's space agency has released images that show the Moon after part of a SpaceX rocket crashed into its surface on Wednesday. Rocket debris struck the Moon at around 06:35 GMT on Wednesday, according to the South Korean space agency. Re-usable Falcon 9 rockets were designed to allow part of the rocket to return to Earth (the upper stage) and other sections to be shed in space. Its job was to fire the upper stage hard enough to send both of the landers out of Earth's orbit and onto a path towards the Moon. The spent stage was left drifting in a long, looping orbit that swung out towards the Moon and back again.
