RKK Energia Museum of S.P. Korolev in Korolyov is the corporate museum of the Roscosmos-affiliated Energia rocket-and-space corporation, established in 1963. Its demonstration hall interprets the Soviet and Russian human-spaceflight programme with flown Vostok descent vehicles including Yuri Gagarin’s, Voskhod-2 hardware linked to Alexei Leonov’s first spacewalk, Soyuz–Apollo and Mir displays, satellites, interplanetary spacecraft and early R-1, R-2 and R-5M rockets. A memorial room recreates Sergei Korolev’s office, while the labour-history hall documents the engineers, scientists and cosmonauts behind the enterprise; a second site presents later rocket and spacecraft development. Visits are advance-arranged group excursions inside the enterprise, so confirm current registration, security and accessibility requirements with the operator. Visitor address: 4A Lenina Street, Korolyov, Moscow Region 141070, Russia.
