Here Tsiolkovsky evaluated the work needed to overcome the force of gravity, determined the speed needed to propel the device into the solar system ("escape velocity"), and examined calculation of flight time. The publication of this article made a splash in the scientific world, and Tsiolkovsky found many friends among his fellow scientists.
Soyuz (Russian: Союз, IPA:, lit. 'Union') is a series of spacecraft which has been in service since the 1960s, having made more than 140 flights. It was designed for the Soviet space program by the Korolev Design Bureau (now Energia).
Russian involvement in rocketry began in 1903 when Konstantin Tsiolkovsky published a paper on liquid-propelled rockets (LPREs). [1] Tsiolkovsky's efforts made significant advances in the use of liquid fuel. His work challenged traditional thought and sparked a revolution in science which embraced new ideas in rocket technology. [1]
In addition to being the designation for the whole Soviet/Russian reusable spacecraft project, Buran was also the name given to orbiter 1K, which completed one uncrewed spaceflight in 1988 and was the only Soviet reusable spacecraft to be launched into space.
Soyuz crewed missions were the only spacecraft visiting the International Space Station, starting from when the Space Shuttle program ended in 2011, until the launch of Crew Dragon Demo-2 on 30 May 2020. [14] [15] The International Space Station always has at least one Soyuz spacecraft docked at all times for use as an escape craft. [16] [17]
The theory of space exploration had a solid basis in the Russian Empire before the First World War with the writings of the Russian and Soviet rocket scientist Konstantin Tsiolkovsky (1857–1935), who published pioneering papers in the late 19th and early 20th centuries on astronautic theory, including calculating the Rocket equation and in 1929 introduced the concept of the multistaged rocket.
In the early 1960s, when Europe and America were establishing geostationary communication satellites, the Russians found these orbits unsuitable. [6] They were limited in the amount of rocket power available and it is extremely energy intensive to both launch a satellite to 40,000 km, and change its inclination to be over the equator, especially when launched from Russia.
Sputnik 1 (/ ˈ s p ʌ t n ɪ k, ˈ s p ʊ t n ɪ k /, Russian: Спутник-1, Satellite 1), sometimes referred to as simply Sputnik, was the first artificial Earth satellite.It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program.
