Plesetsk Cosmodrome

Plesetsk Cosmodrome (Russian: Космодром «Плесецк», romanized: Kosmodrom "Plesetsk") is a Russian spaceport located in Mirny, Arkhangelsk Oblast, near the town of Plesetsk, from which it takes its name. Until 2025 and the commissioning of the Andøya base in Norway, it was the only operational orbital spaceport in Europe and the northernmost spaceport in the world. Originally developed as an intercontinental ballistic missile (ICBM) site for the R-7 missile, its strategic location approximately 800 kilometres (500 mi) north of Moscow was key to its selection.

Due to its high latitude, Plesetsk is particularly suited for specific types of satellite launches, such as those into Molniya orbits, and historically served as a secondary launch facility. Most Soviet orbital launches were conducted from Baikonur Cosmodrome, located in the Kazakh SSR. However, following the dissolution of the Soviet Union, Baikonur became part of Kazakhstan, which began charging Russia to lease the land for its use. As a result, Plesetsk has seen significantly increased activity since the 2000s, especially for launching military satellites.

Plesetsk (62°55′32.32″N 40°34′40.36″E / 62.9256444°N 40.5778778°E / 62.9256444; 40.5778778) is used especially for military satellites placed into high inclination and polar orbits since the range for falling debris is clear to the north which is largely uninhabited Arctic and polar terrain. It is situated in a region of taiga, or flat terrain with boreal pine forests.

The Soyuz rocket, Cosmos-3M, Rokot, Tsyklon, and Angara are launched from the Plesetsk Cosmodrome. The heavy Proton and Zenit rockets can only be land-launched from Baikonur (Zenit may also be launched at sea). As of 26 December 2017, all Zenit launches are discontinued and all activities are suspended.

Plesetsk Cosmodrome was originally developed by the Soviet Union as a launch site for intercontinental ballistic missiles under the leadership and supervision of lieutenant general Galaktion Alpaidze. On 11 January 1957, the Soviet government passed the resolution about the foundation of a special military object with the secret name "Angara". This secret object had to be situated in Plesetsk District, Arkhangelsk Oblast. It was named after the town of Plesetsk. The first Soviet Combat formation of intercontinental ballistic missiles R-7 of general designer Sergei Korolev had to be located in that place, in thick northern taiga to the south of Arkhangelsk. The official birthday of the proving ground was 15 July 1957. That day Colonel Gregorjev assumed his post as the missile unit commander. By 15 July 1961, four missile complexes for R-7 ICBMs were at combat status.

In January 1963, a joint decision of the Central Committee of the Communist Party of the Soviet Union and the USSR Council of Ministers created the "Research Proving Ground missile and space weapons USSR Ministry of Defense" near the Ilez railway station, Velsky District of Arkhangelsk Oblast. In the summer of 1963, the state leadership decided to use the Plesetsk launch facilities for launching spacecraft. In September 1963, the Council of Ministers of the USSR 3rd ALM and NIIP converted to "53 minutes Research Proving Ground". Three test management, employees of combat duty, tests of rocket and space complexes, holding and processing of telemetry and trajectory measurements.

And from 1964, on the basis of rocket connection started the establishment of research proving ground missiles and space weapons. Such conversion were the favourable geographical location and a significant number of systems already deployed by the end of 1964 were on duty, four launchers R-7A, seven PU P-16U, and three PU R-9A. Since then, the landfill has developed in two directions: rocket and space.

17 March 1966 was the space birthday of Plesetsk. That day was the first missile launching of the rocket booster Vostok with space vehicle Kosmos 112. Since that time, the rocket base "Angara" has become Plesetsk Cosmodrome. Construction started in 1957 and it was declared operational for R-7 rockets in December 1959. The urban-type settlement of Plesetsk in Arkhangelsk Oblast had a railway station, essential for the transport of missile components. A new town for the support of the facility was named Mirny, Russian for "peaceful". By 1997, more than 1,500 launches to space had been made from the site, more than from any other launch facility, although the usage has declined significantly since the break-up of the Soviet Union.
