Space fans: mark 10am this Friday (12 February). That's when tickets go on sale for a sure-fire sell-out that sees Buzz Aldrin in conversation with Brian Cox (or, 'Never mind the Buzz, Cox', as the event should have been titled).
The event at the Science Museum pairs the most famous living astronaut with the second-most-famous physicist-popstar called Brian (after this guy). It takes place on 28 February, but you'll need to be ready to pounce on 12 February if you're going to grab a ticket.
The pair will discuss the past, present and future of spaceflight, particularly Aldrin's campaign to get humans on Mars.
Brian & Buzz in conversation a the Science Museum's IMAX theatre, 28 February 2016. Tickets £10 on sale 12 February, 10am. Image by NASA/M@ and not an official promo shot for the talk.
