How about paying a visit to Russian Space exploration museum? If it seems like a good idea then come inside for it.
The Yuri Gagarin greats your in the hall and invites to see seventy more photos of what inside.
This is the world's first biological satellite, in which Russian dog "Laika" has made its first flight in 1957. It's of actual size on display.
And here her colleague "Belka".
And Belka's partner "Strelka".
And that's an ejecting container for animals from the "Sputnik" or satellite. In this container Belka and Strelka dogs got back to Earth in 1960.
That's boat is called after Gagarin - "Yuri Gagarin scientific research ship". It was used in establishing links with satellites and Russian manned space missions.
