50th anniversary of Yuri Gagarin's flight.

The Guardian is a British newspaper and has a fascinating piece about Sergei Korolev, the man behind the Soviet Space Race. You can read the online version here. They also have a great gallery of Yuri related images here. Yuri is of course probably the inspiration behind the naming of Yuri in episode 2. Hopefully in 3 we will find out his real name.
