As of 2024, it is Europe's only operational orbital spaceport and the northernmost spaceport in the world. Originally developed as an ICBM site for the R-7 missile, it has also served for numerous satellite launches using the R-7 and other rockets. Its high latitude makes it useful only for certain types of launches, especially

2080-593: Is a launch complex used by Russia 's Angara rocket. The complex has a single launch pad , Site 35/1, which was first used for the maiden flight of the Angara in July 2014. Site 35 was originally intended to support the Zenit rocket, which the Soviet Union saw as a replacement for the R-7 series . The construction of a Zenit launch complex at Plesetsk was authorised in 1976; however, development did not begin until

2184-729: Is observing in X-band (center frequency of 9.65 GHz corresponding to a wavelength of 3.1 cm). Prior to an image acquisition, the satellite rolls in an appropriate position and stabilizes its attitude. Then, the SAR image is acquired. After that, the satellite rolls back into its standby attitude and continues to charge its batteries, preparing itself for the next SAR image acquisition. A replacement of SAR-Lupe, called SARah, entered service starting from 2022. It will consist of 2 radar satellites and one optical satellite. The SARah satellites are bigger and more capable than those of SAR-Lupe. SARah-1,

It claimed that

7072-410: The development and expansion of the cosmodrome in 2011. This includes the reconstruction of a local motorway and modernising the energy supply system. New facilities will be built, including a dormitory and hospital. PL-19 Nudol anti-ballistic missile systems are located at the Cosmodrome, at the former launch site of the Tsyklon-2 rocket. Site 16 , also known as SK-2 , is a launch complex at

7176-495: The enactment of the April Novelization , as agreed upon following the Polish Round Table Agreement talks from February to April between the government and the Solidarity trade union. The Polish Solidarity Union, as established through the 1980 August Accords, presented Lech Wałęsa as their candidate, who became the first democratically elected president of Poland. The elections in Poland inspired other Eastern European Soviet Nations to pursue peaceful democratic transitions, and soon

7280-488: The end of 1989, the year the Berlin Wall fell. This was also the year that CNN became the first non-Soviet broadcaster allowed to beam its TV news programs to Moscow. Officially, CNN was available only to foreign guests in the Savoy Hotel , but Muscovites quickly learned how to pick up signals on their home televisions. That had a major effect on how Soviets saw events in their country and made censorship almost impossible. The month-long nomination period for candidates for

7384-399: 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 demands rent for its continued use. Plesetsk is not ideally suited for low inclination or geostationary launches because of its high latitude of 62° north (as compared to

7488-428: 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,

7592-696: The first group release since the Khrushchev Thaw in the mid-1950s. On 10 September, Boris Yeltsin wrote a letter of resignation to Gorbachev. At the 27 October plenary meeting of the Central Committee, Yeltsin, frustrated that Gorbachev had not addressed any of the issues outlined in his resignation letter, criticized the slow pace of reform, and servility to the general secretary. In his reply, Gorbachev accused Yeltsin of "political immaturity" and "absolute irresponsibility". Nevertheless, news of Yeltsin's insubordination and "secret speech" spread, and soon samizdat versions began to circulate. That marked

7696-583: The following days and months. The secession of the Baltic states was recognized in September 1991. The Belovezha Accords were signed on 8 December by President Boris Yeltsin of Russia , President Kravchuk of Ukraine , and Chairman Shushkevich of Belarus , recognizing each other's independence and creating the Commonwealth of Independent States (CIS) to replace the Soviet Union. Kazakhstan

7800-523: The future first president of independent Armenia Levon Ter-Petrossian , formed the eleven-member Karabakh Committee to lead and organize the new movement.

8008-421: The lawyer Anatoly Sobchak . In the first session of the new Congress of People's Deputies (from 25 May to 9 June), hardliners retained control but reformers used the legislature as a platform for debate and criticism, which was broadcast live and uncensored. This transfixed the population since nothing like such a freewheeling debate had ever been witnessed in the Soviet Union. On 29 May, Yeltsin managed to secure

8112-510: The leading rebel republic. On 5 July 1988, when a contingent of troops was sent in to remove demonstrators by force from Yerevan's Zvartnots International Airport , shots were fired and one student protester was killed. In September, further large demonstrations in Yerevan led to the deployment of armored vehicles. In the autumn of 1988 almost all of the 200,000 Azerbaijani minority in Armenia

8216-861: The major conclusion of the Revolutions of 1989 and the end of the Cold War . In the aftermath of the Cold War , several of the former Soviet republics have retained close links with Russia and formed multilateral organizations such as the CIS, the Collective Security Treaty Organization (CSTO), the Eurasian Economic Union (EAEU), and the Union State , for economic and military cooperation. On

8320-489: The march and after a few incidents, dispersed the demonstrators. In 1988, Gorbachev started to lose control of two regions of the Soviet Union, as the Baltic republics were now leaning towards independence, and the Caucasus descended into violence and civil war. On 1 July 1988, the fourth and last day of a bruising 19th Party Conference, Gorbachev won the backing of the tired delegates for his last-minute proposal to create

8424-422: The most prominent Soviet dissident , returned to Moscow shortly after receiving a personal telephone call from Gorbachev telling him that after almost seven years his internal exile for defying the authorities was over.

8528-410: The most suitable. Construction began in 2004 but was not completed until April 2014. The Angara made its maiden flight—in the one-off Angara-1.2pp configuration—from Site 35/1 on 9 July 2014, flying a successful suborbital test mission. The first orbital launch from the site was the inaugural launch of the Angara A5 on 23 December 2014, which carried a mass simulator. A second orbital test flight of

8632-575: The nationalist wind and on 28 May, allowed Armenians to unfurl the red-blue-orange First Armenian Republic flag for the first time in almost 70 years to mark the 1918 declaration of the First Republic. On 15 June 1988, the Armenian Supreme Soviet adopted a resolution formally approving the idea of Nagorno-Karabakh's unification as part of the republic. Armenia, formerly one of the most loyal republics, had suddenly turned into

8736-544: The orbit of the Kosmos 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

8840-482: The other hand, the Baltic states and all of the other former Warsaw Pact states became part of the European Union (EU) and joined NATO , while some of the other former Soviet republics like Ukraine, Georgia and Moldova have been publicly expressing interest in following the same path since the 1990s, despite Russian attempts to persuade them otherwise. Mikhail Gorbachev was elected General Secretary by

8944-731: The republic's legislature in November 1988 calling for Georgia's independence and in support of Estonia's declaration of sovereignty. Beginning in February 1988, the Democratic Movement of Moldova (formerly Moldavia) organized public meetings, demonstrations, and song festivals, which gradually grew in size and intensity. In the streets, the center of public manifestations was the Stephen the Great Monument in Chișinău, and

9048-587: The republics had already been scheduled to take place between December and March 1990. The six Warsaw Pact countries of Eastern Europe, while nominally independent, were widely recognized as the Soviet satellite states (along with Mongolia ). All had been occupied by the Soviet Red Army in 1945, had Soviet-style socialist states imposed upon them, and had very restricted freedom of action in either domestic or international affairs. Any moves towards real independence were suppressed by military force – in

9152-562: 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

9256-475: The satellite maintains a fixed orientation over the Earth, and the radar image is formed simply by the satellite's motion along its orbit). Response time for imaging of a given area is 10 hours or less. Thales Alenia Space provided the core of the synthetic-aperture radar sensors. The SAR-Lupe satellites are the first German military satellites. The testing of SAR-Lupe involved an inverse procedure, in which

9360-799: The satellite, mounted in a radome on Earth, was used to image the International Space Station , whose orbit is reasonably close to the one the satellite will eventually be in. One-metre resolution at the ISS was apparently achieved. On 30 July 2002 a cooperation treaty between Germany and France was signed, under which the SAR-Lupe satellites and the French Helios optical reconnaissance satellite will operate jointly. Other EU countries have been invited to join as well, and Italy has shown considerable interest. XSAR of SAR-Lupe

On 5 June 1988, as the official celebrations of the Millennium were held in Moscow,

9568-539: The site, more than from any other launch facility, although the usage has declined significantly since the break-up of the Soviet Union. Because Plesetsk was used primarily for military launches, especially Zenit photo reconnaissance satellites , which were launched in large numbers during the 1970s-80s, the USSR did not admit to its existence, but it was discovered by British physics teacher Geoffrey Perry and his students at Kettering Grammar School , who carefully analysed

9672-430: The square by force, and imposed a curfew that lasted ten months. The rebellion of fellow Armenians in Nagorno-Karabakh had an immediate effect in Armenia itself. Daily demonstrations, which began in the Armenian capital Yerevan on 18 February, initially attracted few people, but each day the Nagorno-Karabakh issue became increasingly prominent and the numbers swelled. On 20 February, a 30,000-strong crowd demonstrated in

All 122 Tsyklon-3 launches were conducted from the site. 57 launches were recorded as having been from pad 1 and 65 were recorded from pad 2. Site 35 at the Plesetsk Cosmodrome

10088-537: Was expelled by Armenian nationalists, with over 100 killed in the process. That, after the Sumgait pogrom earlier that year, which had been carried out by Azerbaijanis to ethnic Armenians and led to the expulsion of Armenians from Azerbaijan, was for many Armenians considered an act of revenge for the killings at Sumgait. On 25 November 1988, a military commandant took control of Yerevan as the Soviet government moved to prevent further ethnic violence. On 7 December 1988,

10296-476: 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,

10400-558: Was not used again until 1984. On 18 June 1987, a Soyuz-U rocket exploded at liftoff on Pad 3. Both were rebuilt, and are in service as of 2009.

This secret object had to be situated in Plesetsk District , Arkhangelsk Oblast. It

10608-433: Was placed on Site 41. It would have had a response time of 8–12 hours should an order have been given to launch it. No launches were conducted from Site 41 whilst it was operational. In 1963, the complex was converted for use by carrier rockets . The first launch from the complex was a suborbital test of an R-7A Semyorka missile, on 14 December 1965. The first orbital launch from the complex occurred on 17 March 1966, when

10712-495: Was the last republic to leave the Union, proclaiming independence on 16 December. All the ex-Soviet republics, with the exception of Georgia and the Baltic states, joined the CIS on 21 December, signing the Alma-Ata Protocol . Russia, as by far the largest and most populous republic, became the USSR's de facto successor state . On 25 December, Gorbachev resigned and turned over his presidential powers—including control of

10816-595: Was the uncensored live TV coverage of the legislature's deliberations, where people witnessed the previously feared Communist leadership being questioned and held accountable. This example fueled a limited experiment with democracy in Poland , which quickly led to the toppling of the Communist government in Warsaw that summer and in turn sparked uprisings that overthrew governments in the other five Warsaw Pact countries before
