We're taking a look at the lost cosmonaut theory this week. Yuri Gagarin was the first person to enter space on April 12, 1961 - but what if he wasn't? What if he was just the first one to make it back? We examine the idea that maybe there were other cosmonauts before Yuri whose journeys weren't so successful. 

We’ve teamed up with the brand new Space and Beyond Box from Astronomy magazine to give away one one-year subscription to the Space & Beyond Box and five first boxes!
