Energia Museumis one of the most important space museums in the world. The exhibitions here have significant historical values including a real Vostok-1 descent module returned to the earth after the world's first manned space flight by Yuri. A. Gagarin.
RSC Energia took the leadership of almost all the space development activities of early stage in Soviet Union under S. P. Korelov. RSC Energia developed not only rockets but also various satellites including Sputnik-1, the world's first satellite. As a museum within RSC Energia, many of the satellite models exhibited here are not simple "mock-ups" but proto models, development models, engineering models or even flight spares.

the world's first satellite, was packaged in a two semispheric containers with the diameter of 580 mm. Its structure was made of 2mm thick aluminum and connected by 36 bolts using O-ring seal. Satellite mass was 83.6kg. The satellite carried the followings:
Radio transmitters D-200 transmitting signals "beep beep beep" lasting 0.4 seconds at frequencies of 20 and 40 MHz.
Power supply made of three silver-zinc batteries .
Thermal control system composed of thermal control switches and a ventilation fan.
Two sets of antennas: one with two 2.4-meter elements, another two 3.9 meter elements.
Sputonik-1 was launched by R-7 rocket from Baikonur Cosmodrome at 22:28 of October 4th, 1957 (Moscow time), and was said to be injected into an orbit of perigee 228 km and apogee 947 km with an inclination of 65.1 degrees.
The Sputnik-1 transmitted signals for 22 days before its batteries went out. The satellite circled 1,440 orbits and re-entered into the Earth's atmosphere on January 4, 1958, 92 days in space after launch.
Although the Sputonik-1 was a very simple satellite, the following scientific data was obtained:
Density of the upper atmosphere from the rate of decay of its orbit,
Radio wave propagation through the ionosphere.
The success of the Sputnik-1 provided dreams of Space to many people all over the world, and the Space Age started with the Sputnik-1. At the same time it also shocked the United States that the USSR can strike the US territory with nuclear weapons by ballistic missiles.
The museum has three exhibition area: a large exhibition hall, the Labour Glory hall and the Memorial Room devoted to S.P. Korolev.

There are several manned spacecraft exhibitions on the first floor of the exhibition hall. Real descent module of Vostok -1, the world's first manned flight by Yuri Gagarin and other descent modules with significant historical values can be seen only here.
shows the history made by those who contributed space development using photographs, documents, awards, memorable souvenirs and others. The history of RSC Energia was the history of early space development of Soviet Union.

S.P. Korolev is the Father of space development of Soviet Union. He took the leadership of development of early launch vehicles and satellites including the world's first satellite Sputnik-1and the world's first manned flight by Yuri Gararin. However, he is not well-known to the western world because his name had been kept secret until his death.
Memorial room exhibits his personal belongings, many photographs and documents which are today of significant historical value. His work study in Energia is also reconstructed here.
