The general easement of repressive policies became known later as

2641-509: A system of ground stations was to be developed to collect data transmitted by the satellite, observe the satellite's orbit, and transmit commands to the satellite. Because of the limited time frame, observations were planned for only 7 to 10 days and orbit calculations were not expected to be extremely accurate. By the end of 1956, it became clear that the complexity of the ambitious design meant that 'Object D' could not be launched in time because of difficulties creating scientific instruments and

2780-451: A trajectory measurement system called "Tral", developed by OKB MEI (Moscow Energy Institute), by which they received and monitored data from transponders mounted on the R-7 rocket's core stage.

Three attempts to launch the second rocket (8K71 No.6) were made on 10–11 June, but an assembly defect prevented launch. The unsuccessful launch of

10008-545: The control of the Golden Horde and consolidated the whole of northern Rus' under Moscow's dominion, and was the first Russian ruler to take the title "Grand Duke of all Rus'". After the fall of Constantinople in 1453, Moscow claimed succession to the legacy of the Eastern Roman Empire . Ivan III married Sophia Palaiologina , the niece of the last Byzantine emperor Constantine XI , and made

10147-476: The country has experienced democratic backsliding and become an authoritarian dictatorship . Russia has been militarily involved in a number of conflicts in former Soviet states and other countries , including its war with Georgia in 2008 and its war with Ukraine since 2014, which has involved the internationally unrecognised annexations of Ukrainian territory including Crimea in 2014 and four other regions in 2022 during an ongoing invasion . Russia

10286-839: The country was more often referred to by its inhabitants as Rus ' , the Russian land ( Russkaia zemlia ), or the Muscovite state ( Moskovskoe gosudarstvo ), among other variations. In 1721, Peter the Great changed the name of the state from Tsardom of Russia ( Russian : Русское царство , romanized :  Russkoye tsarstvo ) or Tsardom of Muscovy ( Russian : Московское царство , romanized :  Moskovskoye tsarstvo ) to Russian Empire ( Rossiiskaia imperiia ). There are several words in Russian which translate to "Russians" in English. The noun and adjective русский , russkiy refers to ethnic Russians . The adjective российский , rossiiskiy denotes Russian citizens regardless of ethnicity. The same applies to

10425-450: The crucial Battle of Molodi . The death of Ivan's sons marked the end of the ancient Rurik dynasty in 1598, and in combination with the disastrous famine of 1601–1603 , led to a civil war, the rule of pretenders, and foreign intervention during the Time of Troubles in the early 17th century. The Polish–Lithuanian Commonwealth , taking advantage, occupied parts of Russia, extending into

10564-500: The dummy warhead to the target altitude and velocity, reentered the atmosphere, and broke apart at a height of 10 km (6.2 mi) after traveling 6,000 km (3,700 mi). On 27 August, the TASS issued a statement on the successful launch of a long-distance multistage ICBM. The launch of the fifth R-7 rocket (8K71 No.9), on 7 September, was also successful, but the dummy was also destroyed on atmospheric re-entry, and hence needed

10703-575: The earliest known traces of horses in warfare . The genetic makeup of speakers of the Uralic language family in northern Europe was shaped by migration from Siberia that began at least 3,500 years ago. In the 3rd to 4th centuries CE, the Gothic kingdom of Oium existed in southern Russia, which was later overrun by Huns . Between the 3rd and 6th centuries CE, the Bosporan Kingdom , which

10842-513: The efforts of Russian explorers , developing into the Russian Empire , which remains the third-largest empire in history . However, with the Russian Revolution in 1917, Russia's monarchic rule was abolished and eventually replaced by the Russian SFSR —the world's first constitutionally socialist state . Following the Russian Civil War , the Russian SFSR established the Soviet Union with three other Soviet republics , within which it

10981-415: The fan was turned on; when it fell below 20 °C (68 °F), the fan was turned off by the dual thermal switch. If the temperature exceeded 50 °C (122 °F) or fell below 0 °C (32 °F), another control thermal switch was activated, changing the duration of the radio signal pulses. Sputnik 1 was filled with dry nitrogen , pressurized to 1.3  atm (130 kPa). The satellite had

11120-481: The first Europeans to reach and colonise Alaska . In 1803–1806, the first Russian circumnavigation was made. In 1820, a Russian expedition discovered the continent of Antarctica . During the Napoleonic Wars , Russia joined alliances with various European powers, and fought against France. The French invasion of Russia at the height of Napoleon's power in 1812 reached Moscow, but eventually failed as

11259-564: The first Russian feudal representative body (the Zemsky Sobor ), revamped the military, curbed the influence of the clergy, and reorganised local government. During his long reign, Ivan nearly doubled the already large Russian territory by annexing the three Tatar khanates: Kazan and Astrakhan along the Volga , and the Khanate of Sibir in southwestern Siberia. Ultimately, by the end of

11398-586: The first half of the 19th century, Russia also conquered the Caucasus . Catherine's successor, her son Paul , was unstable and focused predominantly on domestic issues . Following his short reign, Catherine's strategy was continued with Alexander I's (1801–1825) wresting of Finland from the weakened Sweden in 1809, and of Bessarabia from the Ottomans in 1812. In North America, the Russians became

11537-635: The first observations of it in the western world were made at the school observatory in Rodewisch ( Saxony ). News reports at the time pointed out that "anyone possessing a short wave receiver can hear the new Russian earth satellite as it hurtles over this area of the globe." Directions, provided by the American Radio Relay League , were to "Tune in 20 megacycles sharply, by the time signals, given on that frequency. Then tune to slightly higher frequencies. The 'beep, beep' sound of

11676-507: The first orbit the Telegraph Agency of the Soviet Union (TASS) transmitted: "As result of great, intense work of scientific institutes and design bureaus the first artificial Earth satellite has been built". The R-7 core stage, with a mass of 7.5 tonnes and a length of 26 metres, also reached Earth orbit. It was a first magnitude object following behind the satellite and visible at night. Deployable reflective panels were placed on

11815-485: The government, which led to the rise of Russian oligarchs . Many of the newly rich moved billions in cash and assets outside of the country in an enormous capital flight . The depression of the economy led to the collapse of social services—the birth rate plummeted while the death rate skyrocketed, and millions plunged into poverty; while extreme corruption, as well as criminal gangs and organised crime rose significantly. In late 1993, tensions between Yeltsin and

11954-548: The hydrogen bomb payload would be. The R-7 was also known by its GRAU (later GURVO, the Russian abbreviation for "Chief Directorate of the Rocket Forces") designation 8K71. At the time, the R-7 was known to NATO sources as the T-3 or M-104, and Type A. Several modifications were made to the R-7 rocket to adapt it to 'Object D', including upgrades to the main engines, the removal of a 300 kg (660 lb) radio package on

12093-535: The latter deliberately starved to death or otherwise killed 3.3 million Soviet POWs , and a vast number of civilians, as the " Hunger Plan " sought to fulfil Generalplan Ost . Although the Wehrmacht had considerable early success, their attack was halted in the Battle of Moscow . Subsequently, the Germans were dealt major defeats first at the Battle of Stalingrad in the winter of 1942–1943, and then in

12232-628: The launch of America's secret WS-117L spy satellites, the U.S. had launched Project Vanguard as its own "civilian" satellite entry for the International Geophysical Year. Eisenhower greatly underestimated the reaction of the American public, who were shocked by the launch of Sputnik and by the televised failure of the Vanguard Test Vehicle 3 launch attempt. The sense of anxiety was inflamed by Democratic politicians and professional cold warriors, who portrayed

12371-533: The launch of Sputnik, a poll conducted and published by the University of Michigan showed that 26% of Americans surveyed thought that Russian sciences and engineering were superior to that of the United States. (A year later, however, that figure had dropped to 10% as the U.S. began launching its own satellites into space.) One consequence of the Sputnik shock was the perception of a " missile gap ". This became

12510-527: The launch site would be collected at six separate observatories and telegraphed to NII-4 . Located back in Moscow (at Bolshevo ), NII-4 was a scientific research arm of the Ministry of Defence that was dedicated to missile development. The six observatories were clustered around the launch site, with the closest situated 1 km (0.62 mi) from the launch pad. A second, nationwide observation complex

12649-667: The low specific impulse produced by the completed R-7 engines (304 seconds instead of the planned 309 to 310 seconds). Consequently, the government rescheduled the launch for April 1958. Object D would later fly as Sputnik 3 . Fearing the U.S. would launch a satellite before the USSR, OKB-1 suggested the creation and launch of a satellite in April–May 1957, before the IGY began in July 1957. The new satellite would be simple, light (100 kg or 220 lb), and easy to construct, forgoing

12788-686: The meantime, both the Bolsheviks and White movement carried out campaigns of deportations and executions against each other, known respectively as the Red Terror and White Terror . By the end of the violent civil war, Russia's economy and infrastructure were heavily damaged, and as many as 10 million perished during the war, mostly civilians. Millions became White émigrés , and the Russian famine of 1921–1922 claimed up to five million victims. On 30 December 1922, Lenin and his aides formed

12927-439: The military to education systems. The federal government began investing in science, engineering, and mathematics at all levels of education. An advanced research group was assembled for military purposes. These research groups developed weapons such as ICBMs and missile defense systems, as well as spy satellites for the U.S. Initially, U.S. President Dwight Eisenhower was not surprised by Sputnik 1. He had been forewarned of

13066-545: The mission. A fuel regulator in the booster also failed around 16 seconds into launch, which resulted in excessive RP-1 consumption for most of the powered flight and the engine thrust being 4% above nominal. Core stage cutoff was intended for T+296 seconds, but the premature propellant depletion caused thrust termination to occur one second earlier when a sensor detected overspeed of the empty RP-1 turbopump. There were 375 kg (827 lb) of LOX remaining at cutoff. At 19.9 seconds after engine cut-off, PS-1 separated from

13205-609: The more recently coined noun россиянин , rossiianyn , "Russian" in the sense of citizen of the Russian state. According to the Primary Chronicle , the word Rus' is derived from the Rus' people , who were a Swedish tribe, and where the three original members of the Rurikid dynasty came from. The Finnish word for Swedes, ruotsi , has the same origin. Later archeological studies mostly confirmed this theory. The first human settlement on Russia dates back to

13344-471: The naked eye. What most watchers actually saw was the much more visible 26-metre core stage of the R-7. Shortly after the launch of PS-1, Khrushchev pressed Korolev to launch another satellite to coincide with the 40th anniversary of the October Revolution , on 7 November 1957. The launch of Sputnik 1 surprised the American public, and shattered the perception created by American propaganda of

13483-641: The north-east. Led by Prince Alexander Nevsky , Novgorodians repelled the invading Swedes in the Battle of the Neva in 1240, as well as the Germanic crusaders in the Battle on the Ice in 1242. Kievan Rus' finally fell to the Mongol invasion of 1237–1240, which resulted in the sacking of Kiev and other cities, as well as the death of a major part of the population. The invaders, later known as Tatars , formed

13622-620: The obstinate resistance in combination with the bitterly cold Russian winter led to a disastrous defeat of invaders, in which the pan-European Grande Armée faced utter destruction. Led by Mikhail Kutuzov and Michael Andreas Barclay de Tolly , the Imperial Russian Army ousted Napoleon and drove throughout Europe in the War of the Sixth Coalition , ultimately entering Paris. Alexander I controlled Russia's delegation at

13761-654: The official line. The continued internal struggle in the Bolshevik party culminated in the Great Purge . Under Stalin's leadership, the government launched a command economy , industrialisation of the largely rural country , and collectivisation of its agriculture . During this period of rapid economic and social change, millions of people were sent to penal labour camps , including many political convicts for their suspected or real opposition to Stalin's rule; and millions were deported and exiled to remote areas of

13900-407: The press ; the country also has high levels of perceived corruption . As of 2024, Russia has a high-income economy which ranks eleventh in the world by nominal GDP and fourth at purchasing power parity , relying on its vast mineral and energy resources ; the world's second-largest for oil production and natural gas production . Russia is home to 32 UNESCO World Heritage Sites . According to

14039-417: The proving ground and preparations for the launch of PS-1 began. Compared to the military R-7 test vehicles, the mass of 8K71PS was reduced from 280 to 272 tonnes (617,000 to 600,000 lb), its length with PS-1 was 29.167 metres (95 ft 8.3 in) and the thrust at liftoff was 3.90  MN (880,000  lb f ). PS-1 was not designed to be controlled; it could only be observed. Initial data at

14178-589: The rivalry between the two major European empires came to be known as the Great Game . The late 19th century saw the rise of various socialist movements in Russia. Alexander II was assassinated in 1881 by revolutionary terrorists. The reign of his son Alexander III (1881–1894) was less liberal but more peaceful. Under last Russian emperor, Nicholas II (1894–1917), the Revolution of 1905

14317-513: The rocket. The satellite had a one-watt, 3.5 kg (7.7 lb) radio transmitting unit inside, developed by Vyacheslav I. Lappo from NII-885 , the Moscow Electronics Research Institute, that worked on two frequencies, 20.005 and 40.002 MHz. Signals on the first frequency were transmitted in 0.3 s pulses (near f = 3 Hz) (under normal temperature and pressure conditions on board), with pauses of

14456-419: The rouble. High budget deficits coupled with increasing capital flight and inability to pay back debts, caused the 1998 Russian financial crisis , which resulted in a further GDP decline. Sputnik 1 Sputnik 1 ( / ˈ s p ʌ t n ɪ k , ˈ s p ʊ t n ɪ k / , Russian : Спутник-1 , Satellite 1 ), sometimes referred to as simply Sputnik , was the first artificial Earth satellite . It

14595-418: The same duration filled by pulses on the second frequency. Analysis of the radio signals was used to gather information about the electron density of the ionosphere. Temperature and pressure were encoded in the duration of radio beeps. A temperature regulation system contained a fan , a dual thermal switch , and a control thermal switch. If the temperature inside the satellite exceeded 36 °C (97 °F),

14734-469: The satellite can be heard each time it rounds the globe." The first recording of Sputnik 1's signal was made by RCA engineers near Riverhead, Long Island. They then drove the tape recording into Manhattan for broadcast to the public over NBC radio. However, as Sputnik rose higher over the East Coast, its signal was picked up by W2AEE, the ham radio station of Columbia University . Students working in

14873-876: The seat of the Metropolitan of the Russian Orthodox Church moved to Moscow in 1325, its influence increased. Moscow's last rival, the Novgorod Republic , prospered as the chief fur trade centre and the easternmost port of the Hanseatic League . Led by Prince Dmitry Donskoy of Moscow, the united army of Russian principalities inflicted a milestone defeat on the Mongol-Tatars in the Battle of Kulikovo in 1380. Moscow gradually absorbed its parent duchy and surrounding principalities, including formerly strong rivals such as Tver and Novgorod . Ivan III ("the Great") threw off

15012-457: The second stage and the satellite's transmitter was activated. These signals were detected at the IP-1 station by Junior Engineer-Lieutenant V.G. Borisov, where reception of Sputnik 1's "beep-beep-beep" tones confirmed the satellite's successful deployment. Reception lasted for two minutes, until PS-1 passed below the horizon. The Tral telemetry system on the R-7 core stage continued to transmit and

15151-402: The spent R-7 second stage at the same time as the satellite was ejected. Tests of the satellite were conducted at OKB-1 under the leadership of Oleg G. Ivanovsky . The control system of the Sputnik rocket was adjusted to an intended orbit of 223 by 1,450 km (139 by 901 mi), with an orbital period of 101.5 minutes. The trajectory had been calculated earlier by Georgi Grechko , using

15290-596: The state of the Golden Horde , which ruled over Russia for the next two centuries. Only the Novgorod Republic escaped foreign occupation after it agreed to pay tribute to the Mongols. Galicia-Volhynia would later be absorbed by Lithuania and Poland , while the Novgorod Republic continued to prosper in the north. In the northeast, the Byzantine-Slavic traditions of Kievan Rus' were adapted to form

15429-418: The third R-7 rocket (8K71 No.7) took place on 12 July. An electrical short caused the vernier engines to put the missile into an uncontrolled roll which resulted in all of the strap-ons separating 33 seconds into the launch. The R-7 crashed about 7 km (4.3 mi) from the pad. The launch of the fourth rocket (8K71 No.8), on 21 August at 15:25 Moscow Time , was successful. The rocket's core boosted

15568-523: The time Chechen separatists declared independence in the early 1990s, an intermittent guerrilla war was fought between the rebel groups and Russian forces. Terrorist attacks against civilians were carried out by Chechen separatists, claiming the lives of thousands of Russian civilians. After the dissolution of the Soviet Union, Russia assumed responsibility for settling the latter's external debts. In 1992, most consumer price controls were eliminated, causing extreme inflation and significantly devaluing

15707-512: The transmitter batteries depleted on 26 October 1957. On 4 January 1958, after three months in orbit, Sputnik 1 burned up while reentering Earth's atmosphere , having completed 1,440 orbits of the Earth, and travelling a distance of approximately 70,000,000 km (43,000,000 mi). Спутник-1 , romanized as Sputnik-Odin ( pronounced [ˈsputnʲɪk.ɐˈdʲin] ), means 'Satellite-One'. The Russian word for satellite, sputnik ,

15846-575: The university's FM station, WKCR , made a tape of this, and were the first to rebroadcast the Sputnik signal to the American public (or whoever could receive the FM station). The Soviet Union agreed to transmit on frequencies that worked with the United States' existing infrastructure, but later announced the lower frequencies. Asserting that the launch "did not come as a surprise", the White House refused to comment on any military aspects. On 5 October,

15985-610: The world regarding a shift in power to the Soviets. The USSR's launch of Sputnik 1 spurred the United States to create the Advanced Research Projects Agency (ARPA, later DARPA ) in February 1958 to regain a technological lead. In Britain, the media and population initially reacted with a mixture of fear for the future, but also amazement about human progress. Many newspapers and magazines heralded

16124-515: Was Ruthenia . In Russian, the current name of the country, Россия ( Rossiya ), comes from the Byzantine Greek name for Rus', Ρωσία ( Rosía ). A new form of the name Rus ' , Росия ( Rosiya ), was borrowed from the Greek term and first attested in 1387. The name Rossiia appeared in Russian sources in the late 15th century, but until the end of the 17th century

16263-449: Was elected President of the Russian SFSR. In August 1991, a coup d'état attempt by members of Gorbachev's government, directed against Gorbachev and aimed at preserving the Soviet Union, instead led to the end of the Communist Party of the Soviet Union. On 25 December 1991, following the dissolution of the Soviet Union , along with contemporary Russia, fourteen other post-Soviet states emerged. The economic and political collapse of

16402-437: Was a 585-millimetre (23.0 in) diameter sphere, assembled from two hemispheres that were hermetically sealed with O-rings and connected by 36 bolts . It had a mass of 83.6 kilograms (184 lb). The hemispheres were 2 mm thick, and were covered with a highly polished 1 mm-thick heat shield made of an aluminium – magnesium – titanium alloy , AMG6T . The satellite carried two pairs of antennas designed by

16541-631: Was a Hellenistic polity that succeeded the Greek colonies, was also overwhelmed by nomadic invasions led by warlike tribes such as the Huns and Eurasian Avars . The Khazars , who were of Turkic origin , ruled the steppes between the Caucasus in the south, to the east past the Volga river basin, and west as far as Kyiv on the Dnieper river until the 10th century. After them came the Pechenegs who created

16680-528: Was approved, provided that the R-7 completed at least two successful test flights. The R-7 rocket was initially designed as an intercontinental ballistic missile (ICBM) by OKB-1. The decision to build it was made by the Central Committee of the Communist Party of the Soviet Union and the Council of Ministers of the USSR on 20 May 1954. The rocket was the most powerful in the world; it was designed with excess thrust since they were unsure how heavy

16819-559: Was bestowed with the specific proper name 'Fellow-Traveler-One', rather than being designated by the general term 'Satellite-One'. In Russian-language references, Sputnik 1 is recognized by the technical name of 'Satellite-One'. On 17 December 1954, chief Soviet rocket scientist Sergei Korolev proposed a developmental plan for an artificial satellite to the Minister of the Defense Industry, Dimitri Ustinov . Korolev forwarded

16958-471: Was coined in the 18th century by combining the prefix s- ('fellow') and putnik ('traveler'), thereby meaning 'fellow-traveler', a meaning corresponding to the Latin root satelles ('guard, attendant or companion'), which is the origin of English satellite . In English, 'Sputnik' is widely recognized as a proper name; however, this is not the case in Russian. In the Russian language, sputnik

17097-473: Was completed, however, the Soviet Union launched a second satellite, Sputnik 2, on 3 November 1957. Meanwhile, the televised failure of Vanguard TV-3 on 6 December 1957 deepened American dismay over the country's position in the Space Race . The Americans took a more aggressive stance in the emerging space race, resulting in an emphasis on science and technological research, and reforms in many areas from

17236-414: Was detected on its second orbit. The designers, engineers, and technicians who developed the rocket and satellite watched the launch from the range. After the launch they drove to the mobile radio station to listen for signals from the satellite. They waited about 90 minutes to ensure that the satellite had made one orbit and was transmitting before Korolev called Soviet premier Nikita Khrushchev . On

17375-602: Was dissolved by the All-Russian Central Executive Committee . An alternative socialist establishment co-existed, the Petrograd Soviet , wielding power through the democratically elected councils of workers and peasants, called soviets . The rule of the new authorities only aggravated the crisis in the country instead of resolving it, and eventually, the October Revolution , led by Bolshevik leader Vladimir Lenin , overthrew

17514-555: Was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's success was unanticipated by the United States . This precipitated the American Sputnik crisis and triggered the Space Race . The launch was the beginning of a new era of political, military, technological, and scientific developments. The word sputnik

17653-919: Was established to track the satellite after its separation from the rocket. Called the Command-Measurement Complex, it consisted of the coordination center in NII-4 and seven distant stations situated along the line of the satellite's ground track . These tracking stations were located at Tyuratam , Sary-Shagan , Yeniseysk , Klyuchi , Yelizovo , Makat in Guryev Oblast , and Ishkup in Krasnoyarsk Krai . Stations were equipped with radar , optical instruments, and communications systems. Data from stations were transmitted by telegraphs into NII-4 where ballistics specialists calculated orbital parameters. The observatories used

17792-515: Was found at Kostyonki–Borshchyovo , and at Sungir , dating back to 34,600 years ago—both in western Russia . Humans reached Arctic Russia at least 40,000 years ago, in Mamontovaya Kurya . Ancient North Eurasian populations from Siberia genetically similar to Mal'ta–Buret' culture and Afontova Gora were an important genetic contributor to Ancient Native Americans and Eastern Hunter-Gatherers . The Kurgan hypothesis places

17931-581: Was half Neanderthal and half Denisovan, and lived some 90,000 years ago, was also found within the latter cave. Russia was home to some of the last surviving Neanderthals, from about 45,000 years ago, found in Mezmaiskaya cave . The first trace of an early modern human in Russia dates back to 45,000 years, in Western Siberia . The discovery of high concentration cultural remains of anatomically modern humans , from at least 40,000 years ago,

18070-518: Was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program . It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries became depleted. Aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere 58 cm (23 in) in diameter with four external radio antennas to broadcast radio pulses. Its radio signal

18209-685: Was located and tracked by the British using the Lovell Telescope at the Jodrell Bank Observatory , the only telescope in the world able to do so by radar. Canada's Newbrook Observatory was the first facility in North America to photograph Sputnik 1. Sputnik 1 was designed to meet a set of guidelines and objectives such as: The chief constructor of Sputnik 1 at OKB-1 was Mikhail S. Khomyakov. The satellite

18348-476: Was low-key and almost dismissive. Eisenhower was even pleased that the USSR, not the U.S., would be the first to test the waters of the still-uncertain legal status of orbital satellite overflights . Eisenhower had suffered the Soviet protests and shoot-downs of Project Genetrix (Moby Dick) balloons and was concerned about the probability of a U-2 being shot down. To set a precedent for "freedom of space" before

18487-584: Was populated by Finno-Ugrian peoples. From the 7th century onwards, the incoming East Slavs slowly assimilated the native Finno-Ugrians. The establishment of the first East Slavic states in the 9th century coincided with the arrival of Varangians , the Vikings who ventured along the waterways extending from the eastern Baltic to the Black and Caspian Seas. According to the Primary Chronicle ,

18626-439: Was scheduled for 1957. Work on the satellite was to be divided among institutions as follows: Preliminary design work was completed in July 1956 and the scientific tasks to be carried out by the satellite were defined. These included measuring the density of the atmosphere and its ion composition, the solar wind , magnetic fields , and cosmic rays . These data would be valuable in the creation of future artificial satellites;

18765-718: Was sometimes dubbed the "Sputnik craze". The U.S. soon had a number of successful satellites, including Explorer 1, Project SCORE , and Courier 1B . However, public reaction to the Sputnik crisis spurred America to action in the Space Race, leading to the creation of both the Advanced Research Projects Agency (renamed the Defense Advanced Research Projects Agency, or DARPA, in 1972), and NASA (through

18904-401: Was the foundation of the United Nations Security Council . During the war, Soviet civilian and military death were about 26–27 million , accounting for about half of all World War II casualties . The Soviet economy and infrastructure suffered massive devastation, which caused the Soviet famine of 1946–1947 . However, at the expense of a large sacrifice, the Soviet Union emerged as

19043-416: Was the largest and principal constituent. At the expense of millions of lives , the Soviet Union underwent rapid industrialisation in the 1930s and later played a decisive role for the Allies in World War II by leading large-scale efforts on the Eastern Front . With the onset of the Cold War , it competed with the United States for ideological dominance and international influence . The Soviet era of

19182-438: Was the only city in the former Yugoslavia to receive the K2, where it was labeled the K2YU. The only differences with the original K2 were in very minor details. One of the most noticeable differences were the corrugated sides and the pantograph, which was in the first series located at the rear of the tram, instead of the front (however it was eventually moved to the front in the 2000s for easier access). Other series already had

19321-569: Was triggered by the humiliating failure of the Russo-Japanese War . The uprising was put down, but the government was forced to concede major reforms ( Russian Constitution of 1906 ), including granting freedoms of speech and assembly , the legalisation of political parties, and the creation of an elected legislative body, the State Duma . In 1914, Russia entered World War I in response to Austria-Hungary 's declaration of war on Russia's ally Serbia , and fought across multiple fronts while isolated from its Triple Entente allies. In 1916,
