Plesetsk Cosmodrome () is a Russian spaceport, located in Arkhangelsk Oblast, about 800 km north of Moscow and approximately 200 km south of Arkhangelsk.
Currently, the Soyuz rocket, Cosmos-3M, Rockot and Tsyklon are launched from the Plesetsk Cosmodrome. The heavy Proton and Zenit rockets can only be land-launched from Baikonur (Zenit may also be utilized on sea launch).
March 17, 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. 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 around 28° north).
Still, the new all-Russian Angara rocket is designed to be launched primarily from Plesetsk when it comes into service.
The Iranian satellite Sina 1 was launched from Plesetsk Cosmodrome on 27 October 2005.
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-18s and RS-20s that are the backbone of Russia's missile forces. Those missiles are known in the West as the SS-19 Stiletto and the SS-18 Satan.
