Mir EO-3 (also called Mir Principal Expedition 3 ) was an expedition to the space station Mir . The crew consisted of 3 people, Musa Manarov (Commander), Vladimir Titov (Flight Engineer) and Valeri Polyakov (Research Doctor). Manarov and Titov arrived at the station in December 1987 on Soyuz TM-4 , while Polyakov arrived much later, in August 1988 on Soyuz TM-6 . After the arrival of Polyakov, medical experiments became more intensive.

110-501: Upon docking to Mir; Titov and Manarov became the third resident crew. Both performed three EVAs . Polyakov joined the crew later separately. In the first week of the mission they performed biological experiments (with onions and fishes for example) and installed the Aynur biological crystal growth apparatus, which they had delivered to the station, into Kvant-1. Titov and Manarov conducted part of an ongoing survey of galaxies and star groups in

220-635: A famine between 1930 and 1933 that killed millions. The Soviet forced labour camp system of the Gulag was expanded. During the late 1930s, Stalin's government conducted the Great Purge to remove opponents, resulting in mass death, imprisonment, and deportation. In 1939, the USSR and Nazi Germany signed a nonaggression pact , but in 1941, Germany invaded the Soviet Union in the largest land invasion in history, opening

330-641: A 22-minute spacewalk wearing the Chinese-developed Feitian space suit , with taikonaut Liu Boming wearing the Russian-derived Orlan space suit assisting him in the process. Zhai completely exited the craft, while Liu stood by at the airlock, straddling the portal. Since 2021, China has carried out several more extravehicular activities lasting several hours for the construction of the Tiangong space station . American company SpaceX conducted

440-533: A closer relationship with France and Britain. In 1939, half a year after the Munich Agreement , the USSR attempted to form an anti-Nazi alliance with France and Britain. Adolf Hitler proposed a better deal, which would give the USSR control over much of Eastern Europe through the Molotov–Ribbentrop Pact . In September, Germany invaded Poland, and the USSR also invaded later that month, resulting in

550-446: A critical spacecraft malfunction before the EVA could be conducted. Astronauts on the next three Gemini flights ( Eugene Cernan , Michael Collins , and Richard Gordon ), performed several EVAs, but none was able to successfully work for long periods outside the spacecraft without tiring and overheating. Cernan attempted but failed to test an Air Force Astronaut Maneuvering Unit which included

660-515: A greater union which he initially named as the Union of Soviet Republics of Europe and Asia (Russian: Союз Советских Республик Европы и Азии , romanized : Soyuz Sovyetskikh Respublik Evropy i Azii ). Joseph Stalin initially resisted Lenin's proposal but ultimately accepted it, and with Lenin's agreement he changed the name to the Union of Soviet Socialist Republics (USSR), although all republics began as socialist soviet and did not change to

770-592: A new profitable market. In the late 1920s and early 1930s, Stalin ordered Marxist-Leninist parties across the world to strongly oppose non-Marxist political parties, labour unions or other organizations on the left, which they labelled social fascists . In the usage of the Soviet Union, and of the Comintern and its affiliated parties in this period, the epithet fascist was used to describe capitalist society in general and virtually any anti-Soviet or anti-Stalinist activity or opinion. Stalin reversed himself in 1934 with

880-535: A segment on a solar cell. The second EVA was on 30 June 1988 (5h 10m) in which the replacement of a detector block on the Kvant-1 module failed. New tools were delivered to the station and with this the same work was then successful on 20 October 1988 (4h 12m). Mir EO-3 officially concluded on 21 December 1988, when Manarov and Titov returned to Earth in the Soyuz TM-6 spacecraft. The mission in total lasted for 365.94 days,

990-723: A self-contained oxygen system. On November 13, 1966, Edwin "Buzz" Aldrin became the first to successfully work in space without tiring during Gemini XII , the last Gemini mission. Aldrin worked outside the spacecraft for 2 hours and 6 minutes, in addition to two stand-up EVAs in the spacecraft hatch for an additional 3 hours and 24 minutes. Aldrin's interest in scuba diving inspired the use of underwater EVA training to simulate weightlessness, which has been used ever since to allow astronauts to practice techniques of avoiding wasted muscle energy. On January 16, 1969, Soviet cosmonauts Aleksei Yeliseyev and Yevgeny Khrunov transferred from Soyuz 5 to Soyuz 4 , which were docked together. This

1100-461: A spacecraft were made by Charles "Pete" Conrad , Joseph Kerwin , and Paul J. Weitz on May 26, June 7, and June 19, 1973, on the Skylab 2 mission. They rescued the functionality of the launch-damaged Skylab space station by freeing a stuck solar panel , deploying a solar heating shield, and freeing a stuck circuit breaker relay. The Skylab 2 crew made three EVAs, and a total of ten EVAs were made by

1210-637: A stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVAs have been conducted by the Soviet Union /Russia, the United States, Canada, the European Space Agency and China. On March 18, 1965, Alexei Leonov became the first human to perform a spacewalk, exiting the Voskhod 2 capsule for 12 minutes and 9 seconds. On July 20, 1969, Neil Armstrong became

1320-615: A status that is retained by the Russian Federation . Covering a sixth of Earth's land surface, its size was comparable to that of North America . Two other successor states, Kazakhstan and Ukraine , rank among the top 10 countries by land area, and the largest country entirely in Europe, respectively. The European portion accounted for a quarter of the country's area and was the cultural and economic center. The eastern part in Asia extended to

1430-469: A union of equals, in practice the Soviet Union was dominated by Russians . The domination was so absolute that for most of its existence, the country was commonly (but incorrectly) referred to as 'Russia'. While the Russian SFSR was technically only one republic within the larger union, it was by far the largest (both in terms of population and area), most powerful, and most highly developed. The Russian SFSR

1540-556: Is derived from the Russian word sovet (Russian: совет ), meaning 'council', 'assembly', 'advice', ultimately deriving from the proto-Slavic verbal stem of * vět-iti ('to inform'), related to Slavic věst ('news'), English wise . The word sovietnik means 'councillor'. Some organizations in Russian history were called council (Russian: совет ). In the Russian Empire ,

1650-627: Is his background, his education , his profession . These are the questions that will determine the fate of the accused. That is the meaning and essence of the Red Terror ." During his rule, Stalin always made the final policy decisions. Otherwise, Soviet foreign policy was set by the commission on the Foreign Policy of the Central Committee of the Communist Party of the Soviet Union , or by

1760-510: The Council of People's Commissars ), headed by the Chairman (Premier) and managing an enormous bureaucracy responsible for the administration of the economy and society. State and party structures of the constituent republics largely emulated the structure of the central institutions, although the Russian SFSR, unlike the other constituent republics, for most of its history had no republican branch of

1870-590: The Eastern Front of World War II . The Soviets played a decisive role in defeating the Axis powers , suffering an estimated 27 million casualties , which accounted for most Allied losses. In the aftermath of the war , the Soviet Union consolidated the territory occupied by the Red Army , forming satellite states , and undertook rapid economic development which cemented its status as a superpower . Geopolitical tensions with

1980-644: The Gemini program was spun off to develop the capability for astronauts to work outside a two-person Earth orbiting spacecraft. However, the Soviet Union was fiercely competitive in holding the early lead it had gained in crewed spaceflight, so the Soviet Communist Party , led by Nikita Khrushchev , ordered the conversion of its single-pilot Vostok capsule into a two- or three-person craft named Voskhod , in order to compete with Gemini and Apollo . The Soviets were able to launch two Voskhod capsules before U.S.

2090-729: The Land Forces , the Air Force , the Navy , Joint State Political Directorate (OGPU) and the Internal Troops . The OGPU later became independent and in 1934 joined the NKVD secret police, and so its internal troops were under the joint leadership of the defense and internal commissariats. After World War II, Strategic Missile Forces (1959), Air Defense Forces (1948) and National Civil Defense Forces (1970) were formed, which ranked first, third, and sixth in

2200-724: The Manned Maneuvering Unit (MMU), and on a flight test in 1994 of the Simplified Aid For EVA Rescue (SAFER), a safety device worn on tethered U.S. EVAs. NASA planners invented the term extravehicular activity (abbreviated with the acronym EVA) in the early 1960s for the Apollo program to land humans on the Moon, because the astronauts would leave the spacecraft to collect lunar material samples and deploy scientific experiments. To support this, and other Apollo objectives,

2310-518: The Moscow State Institute of International Relations . The Marxist-Leninist leadership of the Soviet Union intensely debated foreign policy issues and changed directions several times. Even after Stalin assumed dictatorial control in the late 1920s, there were debates, and he frequently changed positions. During the country's early period, it was assumed that Communist revolutions would break out soon in every major industrial country, and it

2420-644: The Pacific Ocean to the east and Afghanistan to the south, and, except some areas in Central Asia , was much less populous. It spanned over 10,000 kilometres (6,200 mi) east to west across 11 time zones , and over 7,200 kilometres (4,500 mi) north to south. It had five climate zones: tundra , taiga , steppes , desert and mountains . The USSR, like Russia , had the world's longest border , measuring over 60,000 kilometres (37,000 mi), or 1 + 1 ⁄ 2 circumferences of Earth. Two-thirds of it

2530-761: The Popular Front program that called on all Marxist parties to join with all anti-Fascist political, labour, and organizational forces that were opposed to fascism , especially of the Nazi variety. The rapid growth of power in Nazi Germany encouraged both Paris and Moscow to form a military alliance, and the Franco-Soviet Treaty of Mutual Assistance was signed in May 1935. A firm believer in collective security, Stalin's foreign minister Maxim Litvinov worked very hard to form

2640-404: The Soviet Union , was a transcontinental country that spanned much of Eurasia from 1922 to 1991. During its existence, it was the largest country by area , extending across eleven time zones and sharing borders with twelve countries , and the third-most populous country . An overall successor to the Russian Empire , it was nominally organized as a federal union of national republics ,

2750-566: The Soviet republics , and the control of the Communist Party weakened. The failed coup attempt in August 1991 against Gorbachev by hardline communists hastened the end of the Soviet Union , which formally dissolved on December 26, 1991, ending nearly seven decades of Soviet rule. With an area of 22,402,200 square kilometres (8,649,500 sq mi), the Soviet Union was the world's largest country,

2860-739: The State Council , which functioned from 1810 to 1917, was referred to as a Council of Ministers. The Soviets as workers' councils first appeared during the 1905 Russian Revolution . Although they were quickly suppressed by the Imperial army, after the February Revolution of 1917 , workers' and soldiers' Soviets emerged throughout the country and shared power with the Russian Provisional Government . The Bolsheviks, led by Vladimir Lenin , demanded that all power be transferred to

2970-616: The Universal Declaration of Human Rights (1948), saying that it was "overly juridical" and potentially infringed on national sovereignty. The Soviet Union later signed legally-binding human rights documents, such as the International Covenant on Civil and Political Rights in 1973 (and the 1966 International Covenant on Economic, Social and Cultural Rights ), but they were neither widely known or accessible to people living under Communist rule, nor were they taken seriously by

3080-736: The largest arsenal of nuclear weapons in the world . As an Allied nation, it was a founding member of the United Nations as well as one of the five permanent members of the United Nations Security Council . Before its dissolution, the USSR was one of the world's two superpowers through its hegemony in Eastern Europe, global diplomatic and ideological influence (particularly in the Global South ), military and economic strengths, and scientific accomplishments. The word soviet

3190-534: The right to food , the right to work , and the right to education . The Soviet conception of human rights was very different from international law . According to Soviet legal theory , "it is the government who is the beneficiary of human rights which are to be asserted against the individual". The Soviet state was considered as the source of human rights. Therefore, the Soviet legal system considered law an arm of politics and it also considered courts agencies of

3300-556: The ultraviolet part of the spectrum using the Glazar telescope on Kvant. The survey required photography with exposure times of up to 8 minutes. Other work included Earth observation and experiments on the fields of materials sciences, meteorology , space technology, physiology , psychology , medical sciences and astronomical research, using the Marija-research apparatus. In total the crew performed over 2000 experiments. In June 1988,

3410-683: The 1920s, it refused to rubber stamp proposals from the party and Council of Ministers. In 1990, Gorbachev introduced and assumed the position of the President of the Soviet Union , concentrated power in his executive office, independent of the party, and subordinated the government, now renamed the Cabinet of Ministers of the USSR , to himself. Tensions grew between the Union-wide authorities under Gorbachev, reformists led in Russia by Boris Yeltsin and controlling

3520-476: The 1950s, the Soviet Union expanded its efforts in space exploration and took a lead in the Space Race with the first artificial satellite , the first human spaceflight , the first space station , and the first probe to land on another planet . In 1985, the last Soviet leader, Mikhail Gorbachev , sought to reform the country through his policies of glasnost and perestroika . In 1989, various countries of

3630-585: The 1990s, people in the West were also interested in the radioactive hazards of nuclear facilities, decommissioned nuclear submarines , and the processing of nuclear waste or spent nuclear fuel . It was also known in the early 1990s that the USSR had transported radioactive material to the Barents Sea and Kara Sea , which was later confirmed by the Russian parliament. The crash of the K-141 Kursk submarine in 2000 in

3740-519: The CPSU, being ruled directly by the union-wide party until 1990. Local authorities were organized likewise into party committees , local Soviets and executive committees . While the state system was nominally federal, the party was unitary. The state security police (the KGB and its predecessor agencies ) played an important role in Soviet politics. It was instrumental in the Red Terror and Great Purge , but

3850-518: The Communist authorities. Under Joseph Stalin , the death penalty was extended to adolescents as young as 12 years old in 1935. Sergei Kovalev recalled "the famous article 125 of the Constitution which enumerated all basic civil and political rights" in the Soviet Union. But when he and other prisoners attempted to use this as a legal basis for their abuse complaints, their prosecutor's argument

3960-533: The Politburo after the deaths of Lenin and Stalin, as well as after Khrushchev's dismissal, itself due to a decision by both the Politburo and the Central Committee. All leaders of the Communist Party before Gorbachev died in office, except Georgy Malenkov and Khrushchev, both dismissed from the party leadership amid internal struggle within the party. Between 1988 and 1990, facing considerable opposition, Mikhail Gorbachev enacted reforms shifting power away from

4070-703: The Russian Soviet Federative Socialist Republic (RSFSR), the world's first constitutionally socialist state . The revolution was not accepted by all within the Russian Republic , resulting in the Russian Civil War . The RSFSR and its subordinate republics were merged into the Soviet Union in 1922. Following Lenin's death in 1924, Joseph Stalin came to power, inaugurating rapid industrialization and forced collectivization that led to significant economic growth but contributed to

4180-470: The Russian name of the Soviet Union as СС has been taboo, the reason being that СС as a Russian Cyrillic abbreviation is associated with the infamous Schutzstaffel of Nazi Germany , as SS is in English. In English-language media, the state was referred to as the Soviet Union or the USSR. The Russian SFSR dominated the Soviet Union to such an extent that, for most of the Soviet Union's existence, it

4290-463: The Shipka program. The visiting EP-2 crew returned to Earth about a week later in the spacecraft Soyuz TM-4 , leaving TM-5 as the station's lifeboat. On 31 August 1988, the spacecraft Soyuz TM-6 arrived at the station, carrying the new EO-3 crew member Valeri Polyakov . Also on TM-6 was the two-person crew of the visiting expedition Mir EP-3 , consisting of the commander Vladimir Lyakhov , as well as

4400-613: The Soviet Union and turned into SSRs, which was not recognized by most of the international community and was considered an illegal occupation . After the Soviet invasion of Finland , the Karelo-Finnish SSR was formed on annexed territory as a Union Republic in March 1940 and then incorporated into Russia as the Karelian ASSR in 1956. Between July 1956 and September 1991, there were 15 union republics (see map below). While nominally

4510-525: The Soviet Union . Boris Yeltsin , the leader of the RSFSR, oversaw its reconstitution into the Russian Federation , which became the Soviet Union's successor state; all other republics emerged as fully independent post-Soviet states . During its existence, the Soviet Union produced many significant social and technological achievements and innovations . It had the world's second-largest economy and largest standing military. An NPT-designated state , it wielded

4620-636: The Soviet Union's priorities changed. Despite previous conflict with the United Kingdom , Vyacheslav Molotov dropped his post war border demands. The Cold War was a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc , which began following World War II in 1945. The term cold war is used because there

4730-535: The Soviet Union's superpower status, the economy struggled due to its centralized nature, technological backwardness, and inefficiencies. The vast military expenditures and burdens of maintaining the Eastern Bloc, further strained the Soviet economy. In the 1980s, Mikhail Gorbachev 's policies of Glasnost (openness) and Perestroika (restructuring) aimed to revitalize the Soviet system but instead accelerated its unraveling. Nationalist movements gained momentum across

4840-477: The Soviet authorities admitted. The Soviet Union was the world's second largest producer of harmful emissions. In 1988, total emissions in the Soviet Union were about 79% of those in the United States. But since the Soviet GNP was only 54% of that of the United States, this means that the Soviet Union generated 1.5 times more pollution than the United States per unit of GNP. The Soviet Chernobyl disaster in 1986

4950-773: The Soviets, and gained support from the workers and soldiers. After the October Revolution , in which the Bolsheviks seized power from the Provisional Government in the name of the Soviets, Lenin proclaimed the formation of the Russian Socialist Federal Soviet Republic (RSFSR). During the Georgian Affair of 1922, Lenin called for the Russian SFSR and other national Soviet republics to form

5060-414: The Space Shuttle program were designated as EV-1, EV-2, EV-3 and EV-4 (assigned to mission specialists for each mission, if applicable). For EVAs from the International Space Station , NASA employed a camp-out procedure to reduce the risk of decompression sickness. This was first tested by the Expedition 12 crew. During a camp-out, astronauts sleep overnight in the airlock prior to an EVA, lowering

5170-415: The Supreme Soviet were members of the CPSU. Of the party heads themselves, Stalin (1941–1953) and Khrushchev (1958–1964) were Premiers. Upon the forced retirement of Khrushchev, the party leader was prohibited from this kind of double membership, but the later General Secretaries for at least some part of their tenure occupied the mostly ceremonial position of Chairman of the Presidium of the Supreme Soviet ,

5280-551: The US led to the Cold War . The American-led Western Bloc coalesced into NATO in 1949, prompting the Soviet Union to form its own military alliance, the Warsaw Pact , in 1955. Neither side engaged in direct military confrontation, and instead fought on an ideological basis and through proxy wars . In 1953, following Stalin's death , the Soviet Union undertook a campaign of de-Stalinization under Nikita Khrushchev , which saw reversals and rejections of Stalinist policies. This campaign caused tensions with Communist China . During

5390-430: The USSR. Moscow eventually stopped threatening other states, and instead worked to open peaceful relationships in terms of trade, and diplomatic recognition. The United Kingdom dismissed the warnings of Winston Churchill and a few others about a continuing Marxist-Leninist threat, and opened trade relations and de facto diplomatic recognition in 1922. There was hope for a settlement of the pre-war Tsarist debts, but it

5500-426: The United States resumed EVAs on April 7, 1983, astronauts started using an Extravehicular Mobility Unit (EMU) for self-contained life support independent of the spacecraft. STS-6 was the first Space Shuttle mission during which a spacewalk was conducted. Also, for the first time, American astronauts used an airlock to enter and exit the spacecraft like the Soviets. Accordingly, the American definition of EVA start time

5610-409: The Warsaw Pact overthrew their Soviet-backed regimes , and nationalist and separatist movements erupted across the Soviet Union. In 1991, amid efforts to preserve the country as a renewed federation , an attempted coup against Gorbachev by hardline communists prompted the largest republics—Ukraine, Russia, and Belarus—to secede. On December 26, Gorbachev officially recognized the dissolution of

5720-449: The accident, but this led to a relatively low number of deaths (WHO data, 2005). Another major radioactive accident was the Kyshtym disaster . The Kola Peninsula was one of the places with major problems. Around the industrial cities of Monchegorsk and Norilsk , where nickel , for example, is mined, all forests have been destroyed by contamination, while the northern and other parts of Russia have been affected by emissions. During

5830-471: The air pressure to 10.2 psi (70 kPa), compared to the normal station pressure of 14.7 psi (101 kPa). Spending a night at the lower air pressure helps flush nitrogen from the body, thereby preventing " the bends ". More recently astronauts have been using the In-Suit Light Exercise protocol rather than camp-out to prevent decompression sickness. Soviet Union The Union of Soviet Socialist Republics ( USSR ), commonly known as

5940-429: The country was limited. The state restricted rights of citizens to private property . According to the Universal Declaration of Human Rights , human rights are the "basic rights and freedoms to which all humans are entitled." including the right to life and liberty , freedom of expression , and equality before the law ; and social, cultural and economic rights, including the right to participate in culture ,

6050-442: The creation of new state commissions and committees. It gained additional powers relating to the approval of the Five-Year Plans and the government budget . The Supreme Soviet elected a Presidium (successor of the Central Executive Committee ) to wield its power between plenary sessions, ordinarily held twice a year, and appointed the Supreme Court , the Procurator General and the Council of Ministers (known before 1946 as

6160-409: The degree of power consolidation, it was either the Politburo as a collective body or the General Secretary, who always was one of the Politburo members, that effectively led the party and the country (except for the period of the highly personalized authority of Stalin, exercised directly through his position in the Council of Ministers rather than the Politburo after 1941). They were not controlled by

6270-436: The depressurized cabin through an open hatch. Because of this, the American and Soviet space programs developed different definitions for the duration of an EVA. The Soviet (now Russian ) definition begins when the outer airlock hatch is open and the cosmonaut is in vacuum . An American EVA began when the astronaut had at least their head outside the spacecraft. The USA has changed its EVA definition since. The first EVA

6380-432: The duty of the Russian Bolsheviks to protect what they had in Russia, and avoid military confrontations that might destroy their bridgehead. Russia was now a pariah state, along with Germany. The two came to terms in 1922 with the Treaty of Rapallo that settled long-standing grievances. At the same time, the two countries secretly set up training programs for the illegal German army and air force operations at hidden camps in

6490-531: The first Afghan cosmonaut Abdul Ahad Mohmand . After about a week on the station, Lyakhov and Mohmand returned to Earth in Soyuz TM-5 , leaving the fresh TM-6 spacecraft at the station as their new lifeboat. During the descent of TM-6 there were some technical problems, resulting in some tense moments as well as a day-long delay in landing. Nevertheless, they landed safely on 7 September. The first spacewalk (also known as "Extra-vehicular activity", or EVA) of EO-3 took place on 26 February 1988 (4h 25m) replacing

6600-410: The first human to perform a moonwalk, outside his lunar lander on Apollo 11 for 2 hours and 31 minutes. In 1984, Svetlana Savitskaya became the first woman to perform a spacewalk, conducting EVA outside the Salyut 7 space station for 3 hours and 35 minutes. On the last three Moon missions, astronauts also performed deep-space EVAs on the return to Earth, to retrieve film canisters from the outside of

6710-593: The first private sector-financed EVA on September 12, 2024. Entrepreneur Jared Isaacman and SpaceX engineer Sarah Gillis briefly ventured outside a Dragon capsule, for a stand-up EVA (SEVA) during the Polaris Dawn mission to conduct spacesuit mobility testing. The other two crew members were exposed to the vacuum of space in the capsule, but did not leave it. SpaceX plans to launch at least two more missions involving an EVA, including one that involves SpaceX's still-in-development Starship launch vehicle. The first spacewalk, made by Soviet cosmonaut Alexei Leonov,

In 1924, during the national delimitation in Central Asia, Uzbekistan and Turkmenistan were formed from parts of Russia's Turkestan ASSR and two Soviet dependencies, the Khorezm and Bukharan PSPs . In 1929, Tajikistan was split off from the Uzbekistan SSR. With the constitution of 1936, the Transcaucasian SFSR

6930-410: The general party membership, as the key principle of the party organization was democratic centralism , demanding strict subordination to higher bodies, and elections went uncontested, endorsing the candidates proposed from above. The Communist Party maintained its dominance over the state mainly through its control over the system of appointments . All senior government officials and most deputies of

The post-Stalin leadership, particularly under Nikita Khrushchev , initiated a de-Stalinization process, leading to a period of liberalization and relative openness known as the Khrushchev Thaw . However, the subsequent era under Leonid Brezhnev , referred to as the Era of Stagnation , was marked by economic decline, political corruption, and a rigid gerontocracy . Despite efforts to maintain

7150-438: The government. Extensive extrajudicial powers were given to the Soviet secret police agencies . In practice, the Soviet government significantly curbed the rule of law , civil liberties , protection of law and guarantees of property , which were considered as examples of "bourgeois morality" by Soviet law theorists such as Andrey Vyshinsky . The USSR and other countries in the Soviet Bloc had abstained from affirming

7260-402: The highest bodies of the party and making the Supreme Soviet less dependent on them. The Congress of People's Deputies was established, the majority of whose members were directly elected in competitive elections held in March 1989, the first in Soviet history. The Congress now elected the Supreme Soviet, which became a full-time parliament, and much stronger than before. For the first time since

7370-402: The implementation of socialist policies and the New Economic Policy (NEP), which allowed for market-oriented reforms. The rise of Joseph Stalin in the late 1920s ushered in an era of intense centralization and totalitarianism. Stalin's rule was characterized by the forced collectivization of agriculture , rapid industrialization , and the Great Purge , which eliminated perceived enemies of

The coup failed, and the State Council of the Soviet Union became the highest organ of state power 'in the period of transition'. Gorbachev resigned as General Secretary, only remaining President for the final months of the existence of the USSR. The judiciary

7810-400: The nominal head of state . The institutions at lower levels were overseen and at times supplanted by primary party organizations . However, in practice the degree of control the party was able to exercise over the state bureaucracy, particularly after the death of Stalin, was far from total, with the bureaucracy pursuing different interests that were at times in conflict with the party, nor

7920-603: The official Soviet system of importance (ground forces were second, Air Force fourth, and Navy fifth). The army had the greatest political influence. In 1989, there served two million soldiers divided between 150 motorized and 52 armored divisions. Until the early 1960s, the Soviet navy was a rather small military branch, but after the Caribbean crisis , under the leadership of Sergei Gorshkov , it expanded significantly. It became known for battlecruisers and submarines. In 1989, there served 500 000 men. The Soviet Air Force focused on

8030-531: The only legal party and the final policymaker in the country. At the top of the Communist Party was the Central Committee , elected at Party Congresses and Conferences. In turn, the Central Committee voted for a Politburo (called the Presidium between 1952 and 1966), Secretariat and the general secretary (First Secretary from 1953 to 1966), the de facto highest office in the Soviet Union. Depending on

8140-677: The other order until 1936 . In addition, in the regional languages of several republics, the word council or conciliar in the respective language was only quite late changed to an adaptation of the Russian soviet and never in others, e.g. Ukrainian SSR . СССР (in the Latin alphabet: SSSR ) is the abbreviation of the Russian-language cognate of USSR, as written in Cyrillic letters . The Soviets used this abbreviation so frequently that audiences worldwide became familiar with its meaning. After this,

8250-560: The partition of Poland. In response, Britain and France declared war on Germany, marking the beginning of World War II . Up until his death in 1953, Joseph Stalin controlled all foreign relations of the Soviet Union during the interwar period . Despite the increasing build-up of Germany 's war machine and the outbreak of the Second Sino-Japanese War , the Soviet Union did not cooperate with any other nation, choosing to follow its own path. However, after Operation Barbarossa ,

8360-529: The party's highest body the Politburo . Operations were handled by the separate Ministry of Foreign Affairs . It was known as the People's Commissariat for Foreign Affairs (or Narkomindel), until 1946. The most influential spokesmen were Georgy Chicherin (1872–1936), Maxim Litvinov (1876–1951), Vyacheslav Molotov (1890–1986), Andrey Vyshinsky (1883–1954) and Andrei Gromyko (1909–1989). Intellectuals were based in

8470-491: The pressure in his suit, risking " the bends ". This added another 12 minutes to his time in vacuum, and he was overheated by 1.8 °C (3.2 °F) from the exertion. It would be almost four years before the Soviets tried another EVA. They misrepresented to the press how difficult Leonov found it to work in weightlessness and concealed the problems encountered until after the end of the Cold War . The first American spacewalk

8580-495: The second Bulgarian to fly in space, the first being Georgi Ivanov , who flew on Soyuz 33 but failed to reach Salyut 6 after an engine failure aborted his mission. As a result, Bulgaria was the last Eastern European Soviet ally to not have one of its citizens visit a Soviet space station. Aleksandrov became the first Bulgarian to visit a space station. During his visit, Aleksandrov used nearly 2,000 kg of equipment delivered by Progress spacecraft to conduct 46 experiments in

8690-451: The spacecraft Soyuz TM-5 arrived at the station carrying the three-person visiting crew of Mir EP-2 . The crew consisted of two Soviets, Commander Solovyev and Flight Engineer Savinykh , as well as the Bulgarian research cosmonaut Aleksandr Aleksandrov (not to be confused with Soviet cosmonaut Aleksandr Aleksandrov , who was part of the long-duration Mir EO-2 crew). Aleksandrov was

8800-475: The spacecraft but difficult to use for moving around, contrary to Leonov's claim. However, a defect in the capsule's hatch latching mechanism caused difficulties opening and closing the hatch, which delayed the start of the EVA and put White and his crewmate at risk of not getting back to Earth alive. No EVAs were planned on the next three Gemini flights. The next EVA was planned to be made by David Scott on Gemini VIII , but that mission had to be aborted due to

8910-477: The spacecraft. American Astronauts Pete Conrad , Joseph Kerwin , and Paul Weitz also used EVA in 1973 to repair launch damage to Skylab , the United States' first space station. EVAs may be either tethered (the astronaut is connected to the spacecraft; oxygen and electrical power can be supplied through an umbilical cable ; no propulsion is needed to return to the spacecraft), or untethered. Untethered spacewalks were only performed on three missions in 1984 using

9020-529: The state. The Soviet Union played a crucial role in the Allied victory in World War II , but at a tremendous human cost, with millions of Soviet citizens perishing in the conflict. The Soviet Union emerged as one of the world's two superpowers, leading the Eastern Bloc in opposition to the Western Bloc during the Cold War . This period saw the USSR engage in an arms race, the Space Race , and proxy wars around

9130-469: The struggle for dominance was expressed via indirect means such as psychological warfare , propaganda campaigns, espionage , far-reaching embargoes , rivalry at sports events and technological competitions such as the Space Race . Constitutionally, the USSR was a federation of constituent Union Republics, which were either unitary states, such as Ukraine or Byelorussia (SSRs), or federations, such as Russia or Transcaucasia (SFSRs), all four being

9240-529: The third longest of all the expeditions. Polyakov stayed aboard the station, and was transferred to Mir EO-4 . Extra-vehicular activity Extravehicular activity ( EVA ) is any activity done by an astronaut in outer space outside a spacecraft . In the absence of a breathable Earthlike atmosphere , the astronaut is completely reliant on a space suit for environmental support. EVA includes spacewalks and lunar or planetary surface exploration (commonly known from 1969 to 1972 as moonwalks ). In

9350-591: The three Skylab crews. They found that activities in weightlessness required about 2 1 ⁄ 2 times longer than on Earth because many astronauts suffered spacesickness early in their flights. After Skylab, no more EVAs were made by the United States until the advent of the Space Shuttle program in the early 1980s. In this period, the Soviets resumed EVAs, making four from the Salyut 6 and Salyut 7 space stations between December 20, 1977, and July 30, 1982. When

9460-492: The truth". Human rights in the Soviet Union were severely limited. The Soviet Union was a totalitarian state from 1927 until 1953 and a one-party state until 1990. Freedom of speech was suppressed and dissent was punished. Independent political activities were not tolerated, whether these involved participation in free labour unions , private corporations , independent churches or opposition political parties . The freedom of movement within and especially outside

9570-464: The vacuum of space, stiffening so much that he could not activate the shutter on his chest-mounted camera. At the end of his space walk, the suit stiffening caused a more serious problem: Leonov had to re-enter the capsule through the inflatable cloth airlock, 1.2 m (3 ft 11 in) in diameter and 2.5 m (8 ft 2 in) long. He improperly entered the airlock head-first and got stuck sideways. He could not get back in without reducing

9680-514: The west further raised concerns. In the past, there were accidents involving submarines K-19 , K-8 , a K-129 , K-27 , K-219 and K-278 Komsomolets . There were three power hierarchies in the Soviet Union: the legislature represented by the Supreme Soviet of the Soviet Union , the government represented by the Council of Ministers , and the Communist Party of the Soviet Union (CPSU),

9790-459: The world's largest lakes; the Caspian Sea (shared with Iran ), and Lake Baikal , the world's largest (by volume) and deepest freshwater lake that is also an internal body of water in Russia. Neighbouring countries were aware of the high levels of pollution in the Soviet Union but after the dissolution of the Soviet Union it was discovered that its environmental problems were greater than what

9900-552: Was a coastline . The country bordered Afghanistan , the People's Republic of China , Czechoslovakia , Finland , Hungary , Iran , Mongolia , North Korea , Norway , Poland , Romania , and Turkey from 1945 to 1991. The Bering Strait separated the USSR from the United States . The country's highest mountain was Communism Peak (now Ismoil Somoni Peak ) in Tajikistan , at 7,495 metres (24,590 ft). The USSR also included most of

10010-450: Was able to launch its first crewed Gemini. The Voskhod's avionics required cooling by cabin air to prevent any kind of overheating, therefore an airlock was required for the spacewalking cosmonaut to exit and re-enter the cabin while it remained pressurized. Unusually, and by contrast, the Gemini avionics did not require air cooling, allowing the spacewalking astronaut to exit and re-enter

10120-524: Was also the industrial center of the Soviet Union. Historian Matthew White wrote that it was an open secret that the country's federal structure was 'window dressing' for Russian dominance. For that reason, the people of the USSR were usually called 'Russians', not 'Soviets', since 'everyone knew who really ran the show'. Under the Military Law of September 1925, the Soviet Armed Forces consisted of

10230-480: Was brought under strict party control after Stalin's death. Under Yuri Andropov , the KGB engaged in the suppression of political dissent and maintained an extensive network of informers, reasserting itself as a political actor to some extent independent of the party-state structure, culminating in the anti-corruption campaign targeting high-ranking party officials in the late 1970s and early 1980s. The constitution , which

10340-528: Was carried out within the terms of the Soviet Civil Code. Some Soviet legal scholars even said that "criminal repression" may be applied in the absence of guilt. Martin Latsis , chief of Soviet Ukraine 's secret police explained: "Do not look in the file of incriminating evidence to see whether or not the accused rose up against the Soviets with arms or words. Ask him instead to which class he belongs, what

10450-466: Was colloquially, but incorrectly, referred to as Russia . The history of the Soviet Union began with the ideals of the Bolshevik Revolution and ended in dissolution amidst economic collapse and political disintegration. Established in 1922 following the Russian Civil War , the Soviet Union quickly became a one-party state under the Communist Party . Its early years under Lenin were marked by

10560-574: Was commemorated in 1965 with several Eastern Bloc stamps (see Alexei Leonov#Stamps ). Since the Soviet Union did not publish details of the Voskhod spacecraft at the time, the spaceship depiction in the stamps was purely fictional. The U.S. Post Office issued a postage stamp in 1967 commemorating Ed White 's first American spacewalk. The engraved image has an accurate depiction of the Gemini IV spacecraft and White's space suit . NASA "spacewalkers" during

10670-404: Was dissolved, resulting in its constituent republics of Armenia , Georgia and Azerbaijan being elevated to Union Republics, while Kazakhstan and Kirghizia were split off from the Russian SFSR, resulting in the same status. In August 1940, Moldavia was formed from parts of Ukraine and Soviet-occupied Bessarabia , and Ukrainian SSR. Estonia , Latvia and Lithuania were also annexed by

10780-424: Was no large-scale fighting directly between the two superpowers , but they each supported major regional conflicts known as proxy wars . The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany in 1945. Aside from the nuclear arsenal development and conventional military deployment,

10890-507: Was not independent of the other branches of government. The Supreme Court supervised the lower courts ( People's Court ) and applied the law as established by the constitution or as interpreted by the Supreme Soviet. The Constitutional Oversight Committee reviewed the constitutionality of laws and acts. The Soviet Union used the inquisitorial system of Roman law , where the judge, procurator , and defence attorney collaborate to "establish

11000-504: Was performed on June 3, 1965, by Ed White from the second crewed Gemini flight, Gemini IV , for 21 minutes. White was tethered to the spacecraft, and his oxygen was supplied through a 25-foot (7.6 m) umbilical , which also carried communications and biomedical instrumentation. He was the first to control his motion in space with a Hand-Held Maneuvering Unit , which worked well but only carried enough propellant for 20 seconds. White found his tether useful for limiting his distance from

11110-455: Was performed on March 18, 1965, by Soviet cosmonaut Alexei Leonov , who spent 12 minutes and 9 seconds outside the Voskhod 2 spacecraft. Carrying a white metal backpack containing 45 minutes' worth of breathing and pressurization oxygen, Leonov had no means to control his motion other than pulling on his 15.35 m (50.4 ft) tether. After the flight, he claimed this was easy, but his space suit ballooned from its internal pressure against

11220-481: Was promulgated in 1924 , 1936 and 1977 , did not limit state power. No formal separation of powers existed between the Party, Supreme Soviet and Council of Ministers that represented executive and legislative branches of the government. The system was governed less by statute than by informal conventions, and no settled mechanism of leadership succession existed. Bitter and at times deadly power struggles took place in

11330-608: Was redefined to when the astronaut switches the EMU to battery power. Numerous EVAs were conducted during the assembly of the ISS , often using the Quest Joint Airlock , designed to support both US EMUs, and Russian Orlan space suits. China became the third country to independently carry out an EVA on September 27, 2008, during the Shenzhou 7 mission. Chinese taikonaut Zhai Zhigang completed

11440-477: Was repeatedly postponed. Formal recognition came when the new Labour Party came to power in 1924. All the other countries followed suit in opening trade relations. Henry Ford opened large-scale business relations with the Soviets in the late 1920s, hoping that it would lead to long-term peace. Finally, in 1933, the United States officially recognized the USSR, a decision backed by the public opinion and especially by US business interests that expected an opening of

11550-482: Was that "the Constitution was written not for you, but for American Negroes, so that they know how happy the lives of Soviet citizens are". Crime was determined not as the infraction of law, instead, it was determined as any action which could threaten the Soviet state and society. For example, a desire to make a profit could be interpreted as a counter-revolutionary activity punishable by death. The liquidation and deportation of millions of peasants in 1928–31

11660-587: Was the Russian responsibility to assist them. The Comintern was the weapon of choice. A few revolutions did break out, but they were quickly suppressed (the longest lasting one was in Hungary)—the Hungarian Soviet Republic —lasted only from 21 March 1919 to 1 August 1919. The Russian Bolsheviks were in no position to give any help. By 1921, Lenin, Trotsky, and Stalin realized that capitalism had stabilized itself in Europe and there would not be any widespread revolutions anytime soon. It became

11770-404: Was the first major accident at a civilian nuclear power plant . Unparalleled in the world, it resulted in a large number of radioactive isotopes being released into the atmosphere. Radioactive doses were scattered relatively far. Although long-term effects of the accident were unknown, 4,000 new cases of thyroid cancer which resulted from the accident's contamination were reported at the time of

11880-568: Was the last Apollo astronaut to step off the surface of the Moon. Apollo 15 command module pilot Al Worden made an EVA on August 5, 1971, on the return trip from the Moon, to retrieve a film and data recording canister from the service module. He was assisted by Lunar Module Pilot James Irwin standing up in the Command Module hatch. This procedure was repeated by Ken Mattingly and Charles Duke on Apollo 16 , and by Ronald Evans and Harrison Schmitt on Apollo 17 . The first EVA repairs of

11990-481: Was the party itself monolithic from top to bottom, although factions were officially banned . The Supreme Soviet (successor of the Congress of Soviets ) was nominally the highest state body for most of the Soviet history, at first acting as a rubber stamp institution, approving and implementing all decisions made by the party. However, its powers and functions were extended in the late 1950s, 1960s and 1970s, including

12100-671: Was the second Soviet EVA, and it would be almost another nine years before the Soviets performed their third. American astronauts Neil Armstrong and Buzz Aldrin performed the first EVA on the lunar surface on July 21, 1969 ( UTC ), after landing their Apollo 11 Lunar Module spacecraft. This first Moon walk, using self-contained portable life support systems , lasted 2 hours and 36 minutes. A total of fifteen Moon walks were performed among six Apollo crews, including Charles "Pete" Conrad , Alan Bean , Alan Shepard , Edgar Mitchell , David Scott , James Irwin , John Young , Charles Duke , Eugene Cernan , and Harrison "Jack" Schmitt . Cernan
