Overview

Plesetsk (Lat: 62°55'32.32"N, Lon: 40°34'40.36"E) 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, Rockot, 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).

History

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 special military object with secret name "Angara". This secret object had to be situated in Plesetsk District, Arhangelsk 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 ballistic missile R-7 were at combat status.

In January 1963, a joint decision of the Central Committee of the CPSU and the USSR Council of Ministers created the "Research Proving Ground missile and space weapons USSR Ministry of Defense" near the Ilez railway station, Belsky District of Arkhangelsk Oblast. In the summer of 1963, the leadership of the state is decided on the use of launch facilities in Plesetsk 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 favorable 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 Cosmos 112. Since that time the rocket base Angara has become cosmodrome Plesetsk. 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 for any other launch facility, although the usage has declined significantly since the breakup of the Soviet Union.

The existence of Plesetsk Cosmodrome was originally kept secret, but it was discovered by British physics teacher Geoffrey Perry and his students, who carefully analyzed the orbit of the Cosmos 112 satellite in 1966 and deduced it had not been launched from Baikonur Cosmodrome. Meteor 1-2 satellite launch from Plesetsk on 6 October 1969 was one of the earliest launches observed and photographed from Finland. After the end of the Cold War it was learned that the CIA had begun to suspect the existence of an ICBM launch site at Plesetsk in the late 1950s. The Soviet Union did not officially admit the existence of Plesetsk Cosmodrome until 1983.

The use of the cosmodrome will likely increase in the future since there are concerns with security in operating the Baikonur Cosmodrome in now-independent Kazakhstan, which also demands rent for its continued use. Plesetsk is not ideally suited for low inclination or geostationary launches because of its high latitude of 62 degrees north (as compared to the Guiana Space Centre at 5° north or the Kennedy Space Center at 28° 31′ north).

The new all-Russian Angara rocket was designed to be launched primarily from Plesetsk (and also eventually from the Vostochny Cosmodrome, which is still under construction as of mid-2014). The first test flight of the Angara took place successfully on 9 July 2014.

In May 2007, a new ICBM, called the RS-24 has been tested and launched there, and is seen as eventually replacing the aging RS-18/UR-100Ns (SS-19 Stiletto) and RS-20/R-36Ms (SS-18 Satan) that are the backbone of Russia's missile forces.

In September 2011 Space Forces spokesman Colonel Alexei Zolotukhin said Russia will spend over 5 billion rubles ($170m) on the development and expansion of the cosmodrome in 2011. This includes the reconstruction of a local motorway and modernizing the energy supply system. New facilities will be built, including a dormitory and hospital.
