Earth Artificial Satellites
This part of the exposition tells the story of the begining of the Space Exploration Era, from the very first satellite "Sputnik" whose full-scale engineering test model is in museum, through the "Kosmos" space satellites.

- Sputnik-1. The full-scale engineering test model of "PS-1" (Primitive
Satellite - 1) is located in the musuem. Sputnik was launched into Earth
orbit in October 4, 1957 from Tura-Tam (the Baikonur Cosmodrome). It was
the very first artificial satellite in the world, and it began the Space
Exploration Era. Mass - 83.6 kg., Diameter - 58 cm. Time of orbit - 92 days.
Rocket booster - "Sputnik" (R-7 modification). Designer - Sergey
P. Korolev.


- Sputnik-2. The
full-scale model. The second satellite was launched in November 3, 1957.
The dog "Laika" was on board (bottom sphere with round window).
Mass - about 500 kg. Time of mission - 7 days. Rocket booster - "Sputnik"
(R-7 modification). Designer - Sergey P. Korolev.
- Sputnik-3. The
full-scale model. The third satellite - "Scientific laboratory".
Was launched in May 15, 1958. There were 12 probes for scientific research
of the Earth and near Earth space.
Mass - 1,327 kg. Mass of probes - 968 kg. Time of existanse - till 6.4.1960.
Rocket booster - "Sputnik" (R-7 modification). Designer - Sergey
P. Korolev.
- Kosmos-149. The
full-scale model. The "Kosmos" satellite were used in the Soviet
Union since 1962. "Kosmos-149" (The Space Arrow) was used for
upper atmosphere research. Rocket booster - "Kosmos". Designer
- Mihail K. Yangel. (1911-1971).
- Proton-1. The full-scale model. Heavy earth satellites "Proton"
were launched in 1965-1968 for civil and military purposes. "Proton-1"
was launched in June16,1965. Mass - 12.2 tons Rocket booster - "Proton".
Designer - Vladimir N. Chelomey (1914-1984).
- Molniya-1. The
full-scale model. The first Soviet radio and TV telecommunications satellite.
it was launched in April 23, 1965. Rocket booster - R-7. Designer - Sergey
P. Korolev.
