Keeping time on the moon...
You’re out for a drive, 250,000 miles from Earth. Your flight leaves in 64 minutes. How did the crew of Apollo 17 make it?

Lift-off. It was 12:33am on 7 December 1972, and as the world fell away behind him, Captain Cernan rolled his spaceship through the upper atmosphere before peeling off towards the Moon. For the next four days, he and his crew would float towards their destination at 3,000mph, except for one bit where they'd hit an invisible speed bump, as Earth's gravity lost its grip and they were grabbed by the Moon's. They would flit between moments of flurried activity and the monotony of a mostly empty universe. All the while, their off-the-shelf Speedmasters would be locked onto Houston time, giving them a sense of constant reality on this cosmic trip.
