A block of cheese launched into the upper atmosphere on Tuesday has been found undamaged in Buckinghamshire.
The "interstellar cheddar" landed in Cressex - some 74 miles away - and was taken to High Wycombe police station on Wednesday night, the launch team said.
The wedge was still in one piece but the flight-recording camera had failed.
