Konstantin Tsiolkovsky in the context of "Sergei Korolev"

The Soviet space program (Russian: Космическая программа СССР, romanized: Kosmicheskaya programma SSSR) was the state space program of the Soviet Union, active from 1951 until the dissolution of the Soviet Union in 1991. Contrary to its competitors (NASA in the United States, the European Space Agency in Western Europe, and the Ministry of Aerospace Industry in China), which had their programs run under single coordinating agencies, the Soviet space program was divided between several internally competing design bureaus led by Korolev, Kerimov, Keldysh, Yangel, Glushko, Chelomey, Makeyev, Chertok and Reshetnev. Several of these bureaus were subordinated to the Ministry of General Machine-Building. The Soviet space program served as an important marker of claims by the Soviet Union to its superpower status.

Soviet investigations into rocketry began with the formation of the Gas Dynamics Laboratory in 1921, and these endeavors expanded during the 1930s and 1940s. In the years following World War II, both the Soviet and United States space programs utilised German technology in their early efforts at space programs. In the 1950s, the Soviet program was formalized under the management of Sergei Korolev, who led the program based on unique concepts derived from Konstantin Tsiolkovsky, sometimes known as the father of theoretical astronautics.

The Konstantin E. Tsiolkovsky State Museum of the History of Cosmonautics (Russian: Государственный музей истории космонавтики имени К.Э.Циолковского) is the first museum in the world dedicated to the history of space exploration. It was opened on 3 October 1967 in Kaluga, and is named after Konstantin Tsiolkovsky, a school master and rocket science pioneer who lived most of his life in this city. The driving force behind the creation of the museum was Sergei Korolyov, chief designer of RKK Energiya. The building was designed by Boris Barkhin, Evgeny Kireev, Nataliya Orlova, Valentin Strogy and Kirill Fomin, and the cornerstone was laid by Yuri Gagarin on 13 June 1961. The museum has over 100,000 visitors per year and has 127 employees, of whom 43 are curators.

Kaluga (Russian: Калу́га, IPA: [kɐˈɫuɡə] ) is a city and the administrative center of Kaluga Oblast, Russia. It stands on the Oka River 150 kilometers (93 mi) southwest of Moscow. Its population was 337,058 at the 2021 census.

Kaluga's most famous resident, the space travel pioneer Konstantin Tsiolkovsky, worked there as a school teacher from 1892 to 1935. The Tsiolkovsky State Museum of the History of Cosmonautics in Kaluga is dedicated to his theoretical achievements and to their practical implementations for modern space research, hence the motto on the city's coat of arms: Колыбель Космонавтики, Kolybélʹ kosmonávtiki ("The Cradle of Space-Exploration").

Robert Albert Charles Esnault-Pelterie (French pronunciation: [ʁɔbɛʁ albɛʁ ʃaʁl eno pɛltəʁi]; 8 November 1881 – 6 December 1957) was a French aircraft designer and spaceflight theorist. He is referred to as being one of the founders of modern rocketry and astronautics, along with the Russian Konstantin Tsiolkovsky, the Germans Hermann Oberth, Wernher von Braun and the American Robert H. Goddard.
