A discarded part of a rocket crashed into the Moon’s far side just after noon, scientists say. They were expecting the impact to occur at 12:25 GMT on Friday.
The rocket segment, which weighs three tons, had been tracked for years, but its origin wasn’t clear.
For a time, astronomers thought it belonged to Elon Musk’s SpaceX firm, then they said it was Chinese, which China denies.

The effects of such an impact on the Moon should be pretty minor, experts say.
