Chris and Mr Max are back pounding the sweltering streets of Oxford, enjoying a lovely view of the Moon in the twilight sky. Find out what links Mare Serenitatis - the sea of serenity - with Daft Punk, and hear about the intrepid exploration of the region by the Apollo 17 astronauts while Mr Max equally intrepidly explores a bush. It's hot, but the sky is still beautiful.
