The Memorial Museum of Cosmonautics is one of a kind. It’s a museum dedicated to soviet space exploration. It has about 85,000 items from the space race era including the capsule that Yuri Gagarin used to return to earth. The stuffed bodies of Belka and Strelka are also there. They were the first dogs to go to space and safely return home. There’s a cafe serving space food and a 3-D cinema. Unfortunately all the descriptions on the exhibits are in Russian, but even so it’s worth a visit.
The museum is located inside the Monument to the Conquerors of Space which was erected in 1964 to celebrate the soviet achievements in space exploration. The monument inauguration was on the day of the 7th anniversary of the Sputnik 1 launch. By that time the museum did not exist. It opened 17 years later in 1981 to commemorate the 20th anniversary of the first space flight performed by the inhabitant of the Earth. On 12 April 1961 Yuri Gagarin became the first human to journey into outer space.
The best way to arrive there is to go to VDNKh metro station.
