In this rollicking conversation, Chief Metrologist Dr Bruce Warrington, and Astronomer at Large Prof Fred Watson, will take us on an illustrated journey to reveal some of the very weird and interesting things that happen to time when you’re 100,000 km from Earth.

With no agreed time zones on the Moon, and without the handy technology we use every day such as GPS and the internet, how on Earth will humans be able to agree where, how and when it’s time to set off on our next interplanetary space missions?

Suitable for ages 10+
