12390-408: The Moon. Also, probes were sent throughout the known Solar System, and into Solar orbit. Uncrewed spacecraft have been sent into orbit around Saturn, Jupiter, Mars, Venus, and Mercury by the 21st century, and the most distance active spacecraft, Voyager 1 and 2 traveled beyond 100 times the Earth-Sun distance. The instruments were enough though that it is thought they have left the Sun's heliosphere,
12567-404: The Moon. It set the goal of a lunar landing in 1967—the 50th anniversary of the October Revolution —or 1968. At one stage in the early 1960s the Soviet space program was actively developing multiple launchers and spacecraft. With the fall of Krushchev in 1964, Korolev was given complete control of the crewed program. In 1961, Valentin Bondarenko , a cosmonaut training for a crewed Vostok mission,
12744-518: The OKB-1 design bureau was given to Vasily Mishin , who had the task of sending a human around the Moon in 1967 and landing a human on it in 1968 . Mishin lacked Korolev's political authority and still faced competition from other chief designers. Under pressure, Mishin approved the launch of the Soyuz 1 flight in 1967, even though the craft had never been successfully tested on an uncrewed flight. The mission launched with known design problems and ended with
12921-807: The Russian alphabet include ⟨ ѣ ⟩ , which merged to ⟨ е ⟩ ( /je/ or /ʲe/ ); ⟨ і ⟩ and ⟨ ѵ ⟩ , which both merged to ⟨ и ⟩ ( /i/ ); ⟨ ѳ ⟩ , which merged to ⟨ ф ⟩ ( /f/ ); ⟨ ѫ ⟩ , which merged to ⟨ у ⟩ ( /u/ ); ⟨ ѭ ⟩ , which merged to ⟨ ю ⟩ ( /ju/ or /ʲu/ ); and ⟨ ѧ ⟩ and ⟨ ѩ ⟩ , which later were graphically reshaped into ⟨ я ⟩ and merged phonetically to /ja/ or /ʲa/ . While these older letters have been abandoned at one time or another, they may be used in this and related articles. The yers ⟨ ъ ⟩ and ⟨ ь ⟩ originally indicated
13098-458: The Russian principalities before and especially during Mongol rule. This strengthened dialectal differences, and for a while, prevented the emergence of a standardized national language. The formation of the unified and centralized Russian state in the 15th and 16th centuries, and the gradual re-emergence of a common political, economic, and cultural space created the need for a common standard language. The initial impulse for standardization came from
13275-423: The Solar System are accomplished at a cost in energy, which is described by the net change in velocity of the spacecraft, or delta-v . Due to the relatively high delta-v to reach Mercury and its proximity to the Sun, it is difficult to explore and orbits around it are rather unstable. Venus was the first target of interplanetary flyby and lander missions and, despite one of the most hostile surface environments in
13452-539: The Solar System, has had more landers sent to it (nearly all from the Soviet Union) than any other planet in the Solar System. The first flyby was the 1961 Venera 1 , though the 1962 Mariner 2 was the first flyby to successfully return data. Mariner 2 has been followed by several other flybys by multiple space agencies often as part of missions using a Venus flyby to provide a gravitational assist en route to other celestial bodies. In 1967, Venera 4 became
13629-432: The Soviet Union as part of Operation Osoaviakhim . However, after 1947 the Soviets made very little use of German specialists and their influence on the future Soviet rocket program was marginal. The Soviet space program was tied to the USSR's Five-Year Plans and from the start was reliant on support from the Soviet military. Although he was "single-mindedly driven by the dream of space travel", Korolev generally kept this
13806-495: The Soviet Union's Sputnik 1 , on 4 October 1957, and the first Moon landing by the American Apollo 11 mission on 20 July 1969 are often taken as landmarks for this initial period. The Soviet space program achieved many of the first milestones, including the first living being in orbit in 1957, the first human spaceflight ( Yuri Gagarin aboard Vostok 1 ) in 1961, the first spacewalk (by Alexei Leonov ) on 18 March 1965,
13983-405: The Soviet era can speak Russian, other generations of citizens that do not have any knowledge of Russian. Primary and secondary education by Russian is almost non-existent. In Uzbekistan , Russian is the language of inter-ethnic communication. It has some official roles, being permitted in official documentation and is the lingua franca of the country and the language of the elite. Russian
14160-491: The Soviet's first liquid-fueled rocket GIRD-X . In 1933 GIRD was merged with GDL by the Soviet government to form the Reactive Scientific Research Institute (RNII), which brought together the best of the Soviet rocket talent, including Korolev, Langemak, Ivan Kleymyonov and former GDL engine designer Valentin Glushko . Early success of RNII included the conception in 1936 and first flight in 1941 of
14337-404: The Soviets landing men on the Moon before the United States. Besides the crewed landings, the abandoned Soviet Moon program included the multipurpose moon base Zvezda , first detailed with developed mockups of expedition vehicles and surface modules. Following this setback, Chelomey convinced Ustinov to approve a program in 1970 to advance his Almaz military space station as a means of beating
14514-570: The Soviets valuable experience with space medicine . Because of its global range and large payload of approximately five tons, the reliable R-7 was not only effective as a strategic delivery system for nuclear warheads, but also as an excellent basis for a space vehicle. The United States' announcement in July 1955 of its plan to launch a satellite during the International Geophysical Year greatly benefited Korolev in persuading Soviet leader Nikita Khrushchev to support his plans. In
14691-481: The State Commission for Vostok as part of his duties, was appointed Chairman of the State Commission on Piloted Flights and headed it for the next 25 years (1966–1991). He supervised every stage of development and operation of both crewed space complexes as well as uncrewed interplanetary stations for the former Soviet Union. One of Kerimov's greatest achievements was the launch of Mir in 1986. The leadership of
14868-690: The Sun, beginning with the Apollo Telescope Mount , have been launched and still others have had solar observation as a secondary objective. Parker Solar Probe , launched in 2018, will approach the Sun to within 1/9th the orbit of Mercury. Mercury remains the least explored of the Terrestrial planets . As of May 2013, the Mariner 10 and MESSENGER missions have been the only missions that have made close observations of Mercury. MESSENGER entered orbit around Mercury in March 2011, to further investigate
15045-462: The U.S. remained in flux. The Constellation program aiming for a return to the Moon by 2020 was judged unrealistic by an expert review panel reporting in 2009. Constellation ultimately was replaced with the Artemis Program , of which the first mission occurred in 2022 , with a planned crewed landing to occur with Artemis III . The rise of the private space industry also began in earnest in
15222-439: The US's announced Skylab . Mishin remained in control of the project that became Salyut but the decision backed by Mishin to fly a three-man crew without pressure suits rather than a two-man crew with suits to Salyut 1 in 1971 proved fatal when the re-entry capsule depressurized killing the crew on their return to Earth. Mishin was removed from many projects, with Chelomey regaining control of Salyut. After working with NASA on
15399-653: The US-led Artemis Program, with its plan to build the Lunar Gateway and the Artemis Base Camp , each having its own set of international partners. The first telescope is said to have been invented in 1608 in the Netherlands by an eyeglass maker named Hans Lippershey , but their first recorded use in astronomy was by Galileo Galilei in 1609. In 1668 Isaac Newton built his own reflecting telescope ,
15576-528: The United Arab Emirates. Called the Emirates Mars Mission , it was launched on 19 July 2020 and went into orbit around Mars on 9 February 2021. The uncrewed exploratory probe was named "Hope Probe" and was sent to Mars to study its atmosphere in detail. The Russian space mission Fobos-Grunt , which launched on 9 November 2011, experienced a failure leaving it stranded in low Earth orbit . It
15753-460: The United Nations. Education in Russian is still a popular choice for both Russian as a second language (RSL) and native speakers in Russia, and in many former Soviet republics. Russian is still seen as an important language for children to learn in most of the former Soviet republics. In Belarus , Russian is a second state language alongside Belarusian per the Constitution of Belarus . 77% of
15930-543: The asteroid 4 Vesta , two of the three largest asteroids, were visited by NASA's Dawn spacecraft , launched in 2007. Hayabusa was a robotic spacecraft developed by the Japan Aerospace Exploration Agency to return a sample of material from the small near-Earth asteroid 25143 Itokawa to Earth for further analysis. Hayabusa was launched on 9 May 2003 and rendezvoused with Itokawa in mid-September 2005. After arriving at Itokawa, Hayabusa studied
16107-428: The asteroid's shape, spin, topography, color, composition, density, and history. In November 2005, it landed on the asteroid twice to collect samples. The spacecraft returned to Earth on 13 June 2010. The exploration of Jupiter has consisted solely of a number of automated NASA spacecraft visiting the planet since 1973. A large majority of the missions have been "flybys", in which detailed observations are taken without
16284-549: The automatic Lunokhod and the Luna sample return missions . The Mars probe program was also continued with some success, while the explorations of Venus and then of the Halley comet by the Venera and Vega probe programs were more effective. The "Luna" programme , achieved the first flyby of the moon by Luna 1 in 1959 (also marking the first time a probe reached the far side of the moon),
16461-464: The basis of a permanent crewed space station and crewed exploration of the Moon . However, Dmitry Ustinov directed him to focus on near-Earth missions using the Voskhod spacecraft , a modified Vostok, as well as on uncrewed missions to nearby planets Venus and Mars . Yangel had been Korolev's assistant but with the support of the military, he was given his own design bureau in 1954 to work primarily on
16638-403: The broader sense of expanding the use of Russian alongside or in favour of other languages. The current standard form of Russian is generally regarded as the modern Russian literary language ( современный русский литературный язык – "sovremenny russky literaturny yazyk"). It arose at the beginning of the 18th century with the modernization reforms of the Russian state under the rule of Peter
16815-535: The capital from high-altitude Luftwaffe attacks. In 1942 Korolev was transferred to OKB-SD, where he proposed development of the long range missiles D-1 and D-2. The third design bureau was Plant No 51 (OKB-51) , led by Soviet Ukrainian Engineer Vladimir Chelomey , where he created the first Soviet pulsating air jet engine in 1942, independently of similar contemporary developments in Nazi Germany . During World War II, Nazi Germany developed rocket technology that
16992-460: The class of weakly differentiated melanocratic alkaline gabbroids, similar to terrestrial leucitic basalt with a high potassium content. The acoustic detector returned the sounds of the spacecraft operations and the background wind, estimated to be a speed of around 0.5 m/sec wind. Venera 14 , an identical spacecraft to Venera 13, launched 5 days apart. The mission profiles were very similar, except 14 ran into issues using it's spectrometer to analyze
17169-562: The country. There is an Israeli TV channel mainly broadcasting in Russian with Israel Plus . See also Russian language in Israel . Russian is also spoken as a second language by a small number of people in Afghanistan . In Vietnam , Russian has been added in the elementary curriculum along with Chinese and Japanese and were named as "first foreign languages" for Vietnamese students to learn, on equal footing with English. The Russian language
17346-684: The distinction of being the only object in the Outer Solar System that has been explored with a lander, the Huygens probe deployed by the Cassini spacecraft. The exploration of Uranus has been entirely through the Voyager 2 spacecraft, with no other visits currently planned. Given its axial tilt of 97.77°, with its polar regions exposed to sunlight or darkness for long periods, scientists were not sure what to expect at Uranus. The closest approach to Uranus occurred on 24 January 1986. Voyager 2 studied
17523-533: The energy required at launch to reach Jupiter, albeit at the cost of a significantly longer flight duration. Jupiter has 95 known moons , many of which have relatively little known information about them. Saturn has been explored only through uncrewed spacecraft launched by NASA, including one mission ( Cassini–Huygens ) planned and executed in cooperation with other space agencies. These missions consist of flybys in 1979 by Pioneer 11 , in 1980 by Voyager 1 , in 1982 by Voyager 2 and an orbital mission by
17700-413: The factory and the industrial plant their local peasant dialects with their phonetics, grammar, and vocabulary, and the very process of recruiting workers from peasants and the mobility of the worker population generate another process: the liquidation of peasant inheritance by way of leveling the particulars of local dialects. On the ruins of peasant multilingual, in the context of developing heavy industry,
17877-529: The father of theoretical astronautics . Competing in the Space Race with the United States and later with the European Union and with China , the Soviet space program was notable in setting many records in space exploration, including the first intercontinental missile ( R-7 Semyorka ) that launched the first satellite ( Sputnik 1 ) and sent the first animal ( Laika ) into Earth orbit in 1957, and placed
18054-451: The final reading amendments that state that all schools and kindergartens in the country are to transition to education in Latvian . From 2025, all children will be taught in Latvian only. On 28 September 2023, Latvian deputies approved The National Security Concept, according to which from 1 January 2026, all content created by Latvian public media (including LSM ) should be only in Latvian or
18231-521: The first Sputnik proved to be a successful propaganda coup , Korolev—now known publicly only as the anonymous "Chief Designer of Rocket-Space Systems"—was charged to accelerate the crewed program, the design of which was combined with the Zenit program to produce the Vostok spacecraft . After Sputnik, Soviet scientists and program leaders envisioned establishing a crewed station to study the effects of zero-gravity and
18408-403: The first fully functional telescope of this kind, and a landmark for future developments due to its superior features over the previous Galilean telescope . A string of discoveries in the Solar System (and beyond) followed, then and in the next centuries : the mountains of the Moon , the phases of Venus , the main satellites of Jupiter and Saturn , the rings of Saturn , many comets ,
18585-403: The first human in space in 1961, Yuri Gagarin . In addition, the Soviet program also saw the first woman in space, Valentina Tereshkova , in 1963 and the first spacewalk in 1965. Other milestones included computerized robotic missions exploring the Moon starting in 1959: being the first to reach the surface of the Moon , recording the first image of the far side of the Moon , and achieving
18762-483: The first impact of the moon by Luna 2 , and the first photos of the far side of the moon by Luna 3 . As well as garnering scientific information on the moon, Luna 1 was able to detect a strong flow of ionized plasma emanating from the Sun , streaming through interplanetary space. Luna 2 impacted the moon east of Mare Imbrium . Photography transmitted by Luna 3 showed two dark regions which were named Mare Moscoviense (Sea of Moscow) and Mare Desiderii (Sea of Dreams),
18939-467: The first man-made object to flyby the moon and return to Earth (as well as the first animal to flyby the moon), splashing down in the Indian Ocean. Zond 6 , Zond 7 , and Zond 8 had similar mission profiles, Zond 6 failed to return to earth safely, Zond 7 did however and returned high quality color photography of the earth and the moon from varying distances, Zond 8 successfully returned to earth after
19116-458: The first of which was Galileo , which flew past two: 951 Gaspra in 1991, followed by 243 Ida in 1993. Both of these lay near enough to Galileo' s planned trajectory to Jupiter that they could be visited at acceptable cost. The first landing on an asteroid was performed by the NEAR Shoemaker probe in 2000, following an orbital survey of the object, 433 Eros . The dwarf planet Ceres and
19293-415: The first photography of the surface of Venus. Venera 10 landed on Venus and followed with further photography shortly after. In 1978, Venera 11 and Venera 12 successfully landed, however ran into issues performing photography and soil analysis. Venera 11's light sensor detected lightning strikes. In 1981, Venera 13 performed a successful soft-landing on Venus and marked the first probe to drill into
19470-457: The first probe to enter and directly examine the atmosphere of Venus. In 1970, Venera 7 became the first successful lander to reach the surface of Venus and by 1985 it had been followed by eight additional successful Soviet Venus landers which provided images and other direct surface data. Starting in 1975, with the Soviet orbiter Venera 9 , some ten successful orbiter missions have been sent to Venus, including later missions which were able to map
19647-483: The first soft landing on the Moon. The Soviet program also achieved the first space rover deployment with the Lunokhod programme in 1966, and sent the first robotic probe that automatically extracted a sample of lunar soil and brought it to Earth in 1970, Luna 16 . The Soviet program was also responsible for leading the first interplanetary probes to Venus and Mars and made successful soft landings on these planets in
19824-412: The first soft-landing on the Moon, and successfully transmitted photography from the surface. Luna 10 marked the first man-made object to establish an orbit around the Moon, followed by Luna 11 , Luna 12 , and Luna 14 which also successfully established orbits. Luna 12 was able to transmit detailed photography of the surface from orbit. Luna 10, 12, and Luna 14 conducted Gamma ray spectrometry of
20001-421: The first time a man-made object made contact with another planet after it impacted Venus on March 1, 1966. Venera 4 , Venera 5 , and Venera 6 performed successful atmospheric entry. In 1970 Venera 7 marked the first time a spacecraft was able to return data after landing on another planet. Venera 7 held a resistant thermometer and an aneroid barometer to measure the temperature and atmospheric pressure on
20178-412: The first uncrewed rovers and also successfully brought lunar soil samples to Earth for study. This marked the first (and to date the only) automated return of extraterrestrial soil samples to Earth. Uncrewed exploration of the Moon continues with various nations periodically deploying lunar orbiters. China's Chang'e 4 in 2019 and Chang'e 6 in 2024 achieved the world's first landing and sample return on
20355-529: The formation of the Gas Dynamics Laboratory in 1921, and these endeavors expanded during the 1930s and 1940s. In the years following World War II , both the Soviet and United States space programs utilised German technology in their early efforts at space programs. In the 1950s, the Soviet program was formalized under the management of Sergei Korolev , who led the program based on unique concepts derived from Konstantin Tsiolkovsky , sometimes known as
20532-617: The generation of immigrants who started arriving in the early 1960s). Only about 25% of them are ethnic Russians, however. Before the dissolution of the Soviet Union , the overwhelming majority of Russophones in Brighton Beach, Brooklyn in New York City were Russian-speaking Jews. Afterward, the influx from the countries of the former Soviet Union changed the statistics somewhat, with ethnic Russians and Ukrainians immigrating along with some more Russian Jews and Central Asians. According to
20709-480: The government bureaucracy for the lack of a reliable tool of communication in administrative, legal, and judicial affairs became an obvious practical problem. The earliest attempts at standardizing Russian were made based on the so-called Moscow official or chancery language, during the 15th to 17th centuries. Since then, the trend of language policy in Russia has been standardization in both the restricted sense of reducing dialectical barriers between ethnic Russians, and
20886-471: The government in February 1962 abruptly ordered an ambitious mission involving two Vostoks simultaneously in orbit launched "in ten days time" to eclipse John Glenn 's Mercury-Atlas 6 that month; the program could not do so until August, with Vostok 3 and Vostok 4 . Unlike the American space program, which had NASA as a single coordinating structure directed by its administrator, James Webb through most of
21063-429: The laboratory was renamed the Gas Dynamics Laboratory (GDL). The First test-firing of a solid fuel rocket was carried out in March 1928, which flew for about 1,300 meters Further developments in the early 1930s were led by Georgy Langemak . and 1932 in-air test firings of RS-82 missiles from an Tupolev I-4 aircraft armed with six launchers successfully took place. A key contributor to early soviet efforts came from
21240-459: The last largest moon in the system. Data from Voyager 2 supported the view that Neptune's largest moon, Triton , is a captured Kuiper belt object. The dwarf planet Pluto presents significant challenges for spacecraft because of its great distance from Earth (requiring high velocity for reasonable trip times) and small mass (making capture into orbit difficult at present). Voyager 1 could have visited Pluto, but controllers opted instead for
21417-425: The latter was found to be composed of the smaller Mare Ingenii and other dark craters. Luna 2 marked the first time a man-made object has contacted a celestial body. Luna 1 discovered the Moon had no magnetic field. In 1963, the Soviet Union's "2nd Generation" Luna programme was less successful, Luna 4 , Luna 5 , Luna 6 , Luna 7 , and Luna 8 were all met with mission failures. However, in 1966 Luna 9 achieved
21594-476: The long term effects on lifeforms in a space environment. Still influenced by Tsiolkovsky—who had chosen Mars as the most important goal for space travel—in the early 1960s, the Soviet program under Korolev created substantial plans for crewed trips to Mars as early as 1968 to 1970. With closed-loop life support systems and electrical rocket engines, and launched from large orbiting space stations, these plans were much more ambitious than America's goal of landing on
21771-469: The longest ever Soviet planetary surface mission. Venus and Mars are the two planets outside of Earth on which humans have conducted surface missions with uncrewed robotic spacecraft . Salyut 1 was the first space station of any kind, launched into low Earth orbit by the Soviet Union on 19 April 1971. The International Space Station (ISS) is currently the largest and oldest of the 2 current fully functional space stations, inhabited continuously since
21948-466: The lunar surface, and 400,171 km (248,655 mi) from Earth, marking the record for the farthest humans have ever traveled from Earth in 1970. As of 26 November 2022 Voyager 1 was at a distance of 159 AU (23.8 billion km; 14.8 billion mi) from Earth. It is the most distant human-made object from Earth. Starting in the mid-20th century probes and then human missions were sent into Earth orbit, and then on to
22125-458: The military space program. This had the stronger rocket engine design team including the use of hypergolic fuels but following the Nedelin catastrophe in 1960 Yangel was directed to concentrate on ICBM development. He also continued to develop his own heavy booster designs similar to Korolev's N-1 both for military applications and for cargo flights into space to build future space stations. Glushko
22302-516: The northwestern Xinjiang Uyghur Autonomous Region . Russian was also the main foreign language taught in school in China between 1949 and 1964. In Kazakhstan , Russian is not a state language, but according to article 7 of the Constitution of Kazakhstan its usage enjoys equal status to that of the Kazakh language in state and local administration. The 2009 census reported that 10,309,500 people, or 84.8% of
22479-494: The observations made by Mariner 10 in 1975 (Munsell, 2006b). A third mission to Mercury, scheduled to arrive in 2025, BepiColombo is to include two probes . BepiColombo is a joint mission between Japan and the European Space Agency . MESSENGER and BepiColombo are intended to gather complementary data to help scientists understand many of the mysteries discovered by Mariner 10's flybys . Flights to other planets within
22656-515: The other hand, before the war, almost a quarter of Ukrainians were in favour of granting Russian the status of the state language, while after the beginning of Russia's invasion the support for the idea dropped to just 7%. In peacetime, the idea of raising the status of Russian was traditionally supported by residents of the south and east . But even in these regions, only a third of the respondents were in favour, and after Russia's full-scale invasion , their number dropped by almost half. According to
22833-455: The other three languages in the East Slavic branch. In many places in eastern and southern Ukraine and throughout Belarus, these languages are spoken interchangeably, and in certain areas traditional bilingualism resulted in language mixtures such as Surzhyk in eastern Ukraine and Trasianka in Belarus. An East Slavic Old Novgorod dialect , although it vanished during the 15th or 16th century,
23010-446: The parliament approved a bill to close up all Russian language schools and kindergartens by the school year. The transition to only Estonian language schools and kindergartens will start in the 2024-2025 school year. In Latvia , Russian is officially considered a foreign language. 55% of the population was fluent in Russian in 2006, and 26% used it as the main language with family, friends, or at work. On 18 February 2012, Latvia held
23187-453: The peasants' speech was never systematically studied, as it was generally regarded by philologists as simply a source of folklore and an object of curiosity. This was acknowledged by the noted Russian dialectologist Nikolai Karinsky , who toward the end of his life wrote: "Scholars of Russian dialects mostly studied phonetics and morphology. Some scholars and collectors compiled local dictionaries. We have almost no studies of lexical material or
23364-426: The planet's unique atmosphere and magnetosphere . Voyager 2 also examined its ring system and the moons of Uranus including all five of the previously known moons, while discovering an additional ten previously unknown moons. Images of Uranus proved to have a uniform appearance, with no evidence of the dramatic storms or atmospheric banding evident on Jupiter and Saturn. Great effort was required to even identify
23541-455: The population aged 15 and above, could read and write well in Russian, and understand the spoken language. In October 2023, Kazakhstan drafted a media law aimed at increasing the use of the Kazakh language over Russian, the law stipulates that the share of the state language on television and radio should increase from 50% to 70%, at a rate of 5% per year, starting in 2025. In Kyrgyzstan , Russian
23718-418: The population was fluent in Russian in 2006, and 67% used it as the main language with family, friends, or at work. According to the 2019 Belarusian census , out of 9,413,446 inhabitants of the country, 5,094,928 (54.1% of the total population) named Belarusian as their native language, with 61.2% of ethnic Belarusians and 54.5% of ethnic Poles declaring Belarusian as their native language. In everyday life in
23895-554: The potential use of the space program in a conflict with the US. The Soviet space program was secondary in military funding to the Strategic Rocket Forces ' ICBMs. While the West believed that Khrushchev personally ordered each new space mission for propaganda purposes, and the Soviet leader did have an unusually close relationship with Korolev and other chief designers, Khrushchev emphasized missiles rather than space exploration and
24072-541: The probe had survived the impact and continued transmitting a weak signal for another 23 minutes. It is believed that the spacecraft may have bounced upon impact and come to rest on its side, so the antenna was not pointed towards Earth. In 1972, Venera 8 landed on Venus and measured the light level as being suitable for surface photography, finding it to be similar to the amount of light on Earth on an overcast day with roughly 1 km visibility. In 1975, Venera 9 established an orbit around Venus and successfully returned
24249-586: The probe landing or entering orbit; such as in Pioneer and Voyager programs. The Galileo and Juno spacecraft are the only spacecraft to have entered the planet's orbit. As Jupiter is believed to have only a relatively small rocky core and no real solid surface, a landing mission is precluded. Reaching Jupiter from Earth requires a delta-v of 9.2 km/s, which is comparable to the 9.7 km/s delta-v needed to reach low Earth orbit. Fortunately, gravity assists through planetary flybys can be used to reduce
24426-475: The pronunciation of ultra-short or reduced /ŭ/ , /ĭ/ . Because of many technical restrictions in computing and also because of the unavailability of Cyrillic keyboards abroad, Russian is often transliterated using the Latin alphabet. For example, мороз ('frost') is transliterated moroz , and мышь ('mouse'), mysh or myš' . Once commonly used by the majority of those living outside Russia, transliteration
24603-466: The proper pronunciation of uncommon words or names. Russian is an East Slavic language of the wider Indo-European family . It is a descendant of Old East Slavic , a language used in Kievan Rus' , which was a loose conglomerate of East Slavic tribes from the late 9th to the mid-13th centuries. From the point of view of spoken language , its closest relatives are Ukrainian , Belarusian , and Rusyn ,
24780-491: The respondents), while according to the 2002 census – 142.6 million people (99.2% of the respondents). In Ukraine , Russian is a significant minority language. According to estimates from Demoskop Weekly, in 2004 there were 14,400,000 native speakers of Russian in the country, and 29 million active speakers. 65% of the population was fluent in Russian in 2006, and 38% used it as the main language with family, friends, or at work. On 5 September 2017, Ukraine's Parliament passed
24957-414: The satellite was not punctured by a meteoroid . Sputnik 1 was launched by an R-7 rocket. It burned up upon re-entry on 3 January 1958. The first successful human spaceflight was Vostok 1 ("East 1"), carrying the 27-year-old Russian cosmonaut , Yuri Gagarin , on 12 April 1961. The spacecraft completed one orbit around the globe, lasting about 1 hour and 48 minutes. Gagarin's flight resonated around
25134-697: The soil. Russian language Russian is an East Slavic language belonging to the Balto-Slavic branch of the Indo-European language family . It is one of the four extant East Slavic languages, and is the native language of the Russians . It was the de facto and de jure official language of the former Soviet Union . Russian has remained an official language of the Russian Federation , Belarus , Kazakhstan , Kyrgyzstan , and Tajikistan , and
25311-428: The sole visit to the system as of 2024. The possibility of a Neptune Orbiter has been discussed, but no other missions have been given serious thought. Although the extremely uniform appearance of Uranus during Voyager 2 ' s visit in 1986 had led to expectations that Neptune would also have few visible atmospheric phenomena, the spacecraft found that Neptune had obvious banding, visible clouds, auroras , and even
25488-436: The space exploration programs of the Soviet Union (later Russia), the United States, Europe, Japan and India. Dozens of robotic spacecraft , including orbiters , landers , and rovers , have been launched toward Mars since the 1960s. These missions were aimed at gathering data about current conditions and answering questions about the history of Mars. The questions raised by the scientific community are expected to not only give
25665-715: The surface of Venus using radar to pierce the obscuring atmosphere. Space exploration has been used as a tool to understand Earth as a celestial object. Orbital missions can provide data for Earth that can be difficult or impossible to obtain from a purely ground-based point of reference. For example, the existence of the Van Allen radiation belts was unknown until their discovery by the United States' first artificial satellite, Explorer 1 . These belts contain radiation trapped by Earth's magnetic fields, which currently renders construction of habitable space stations above 1000 km impractical. Following this early unexpected discovery,
25842-506: The surface of another planet and take a sample. Venera 13 also took an audio sample of the Venusian environment, marking another first. Venera 13 returned the first color images of the surface of Venus, revealing an orange-brown flat bedrock surface covered with loose regolith and small flat thin angular rocks. The composition of the sample determined by the X-ray fluorescence spectrometer put it in
26019-753: The surface of the moon. Luna 20 was another successful sample return mission. Luna 18 and Luna 23 resulted in crash landings. In total there were 24 missions in the Luna Programme, 15 were considered to be successful, including 4 hard landings and 3 soft landings, 6 orbits, and 2 flybys. The programme was continued after the collapse of the Soviet union, when the Russian federation space agency launched Luna 25 in 2023. The Venera programme marked many firsts in space exploration and explorations of Venus . Venera 1 and Venera 2 resulted in failure due to losses of contact, Venera 3 , which also lost contact, marked
26196-400: The surface, the transmitted data showed 475 C at the surface, and a pressure of 92 bar. A wind of 2.5 meters/sec was extrapolated from other measurements. The landing point of Venera 7 was 5°S 9°W / 5°S 9°W / -5; -9 . Venera 7 impacted the surface at a somewhat high speed of 17 metres per second, later analysis of the recorded radio signals revealed that
26373-675: The survey carried out by RATING in August 2023 in the territory controlled by Ukraine and among the refugees, almost 60% of the polled usually speak Ukrainian at home, about 30% – Ukrainian and Russian, only 9% – Russian. Since March 2022, the use of Russian in everyday life has been noticeably decreasing. For 82% of respondents, Ukrainian is their mother tongue, and for 16%, Russian is their mother tongue. IDPs and refugees living abroad are more likely to use both languages for communication or speak Russian. Nevertheless, more than 70% of IDPs and refugees consider Ukrainian to be their native language. In
26550-459: The syntax of Russian dialects." After 1917, Marxist linguists had no interest in the multiplicity of peasant dialects and regarded their language as a relic of the rapidly disappearing past that was not worthy of scholarly attention. Nakhimovsky quotes the Soviet academicians A.M Ivanov and L.P Yakubinsky, writing in 1930: The language of peasants has a motley diversity inherited from feudalism. On its way to becoming proletariat peasantry brings to
26727-770: The two. Others divide the language into three groupings, Northern , Central (or Middle), and Southern , with Moscow lying in the Central region. The Northern Russian dialects and those spoken along the Volga River typically pronounce unstressed /o/ clearly, a phenomenon called okanye ( оканье ). Besides the absence of vowel reduction, some dialects have high or diphthongal /e⁓i̯ɛ/ in place of Proto-Slavic * ě and /o⁓u̯ɔ/ in stressed closed syllables (as in Ukrainian) instead of Standard Russian /e/ and /o/ , respectively. Another Northern dialectal morphological feature
26904-506: The use of the language has some presence in certain areas. A large part of the population, especially the older generations, can speak Russian as a foreign language. However, English has replaced Russian as lingua franca in Lithuania and around 80% of young people speak English as their first foreign language. In contrast to the other two Baltic states, Lithuania has a relatively small Russian-speaking minority (5.0% as of 2008). According to
27081-455: The vehicle crashing to the ground, killing Vladimir Komarov . This was the first in-flight fatality of any space program. The Soviets were beaten in sending the first crewed flight around the Moon in 1968 by Apollo 8 , but Mishin pressed ahead with development of the flawed super heavy N1 , in the hope that the Americans would have a setback, leaving enough time to make the N1 workable and land
27258-682: The world's ninth-most spoken language by total number of speakers . Russian is one of two official languages aboard the International Space Station , one of the six official languages of the United Nations , as well as the fourth most widely used language on the Internet . Russian is written using the Russian alphabet of the Cyrillic script ; it distinguishes between consonant phonemes with palatal secondary articulation and those without—the so-called "soft" and "hard" sounds. Almost every consonant has
27435-423: The world; it was a demonstration of the advanced Soviet space program and it opened an entirely new era in space exploration: human spaceflight . The first artificial object to reach another celestial body was Luna 2 reaching the Moon in 1959. The first soft landing on another celestial body was performed by Luna 9 landing on the Moon on 3 February 1966. Luna 10 became the first artificial satellite of
27612-433: The year 2000. The other, Tiangong space station built by China, is now fully crewed and operational. Voyager 1 became the first human-made object to leave the Solar System into interstellar space on 25 August 2012. The probe passed the heliopause at 121 AU to enter interstellar space . The Apollo 13 flight passed the far side of the Moon at an altitude of 254 kilometers (158 miles; 137 nautical miles) above
27789-628: Was a vertical test launch. Although the rocket reached space, it did not reach orbital velocity , and therefore returned to Earth in an impact, becoming the first sub-orbital spaceflight . In 1949, the Bumper-WAC reached an altitude of 393 kilometres (244 mi), becoming the first human-made object to enter space, according to NASA . The first successful orbital launch was of the Soviet uncrewed Sputnik 1 ("Satellite 1") mission on 4 October 1957. The satellite weighed about 83 kg (183 lb), and
27966-405: Was also provided by the Latvian pioneer of rocketry and spaceflight Friedrich Zander , including suggesting in a 1925 paper that a spacecraft traveling between two planets could be accelerated at the beginning of its trajectory and decelerated at the end of its trajectory by using the gravity of the two planets' moons – a method known as gravity assist . The first Soviet development of rockets
28143-458: Was also provided by the Ukrainian and Soviet engineer and mathematician Yuri Kondratyuk who developed the first known lunar orbit rendezvous (LOR), a key concept for landing and return spaceflight from Earth to the Moon . The LOR was later used for the plotting of the first actual human spaceflight to the Moon . Many other aspects of spaceflight and space exploration are covered in his works. Both theoretical and practical aspects of spaceflight
28320-585: Was an essential catalyst to early Soviet efforts. In 1945 and 1946 the use of German expertise was invaluable in reducing the time needed to master the intricacies of the V-2 rocket, establishing production of the R-1 rocket and enable a base for further developments. On 22 October 1946, 302 German rocket scientists and engineers, including 198 from the Zentralwerke (a total of 495 persons including family members), were deported to
28497-480: Was divided between several internally competing design bureaus led by Korolev , Kerimov , Keldysh , Yangel , Glushko , Chelomey , Makeyev , Chertok and Reshetnev . Several of these bureaus were subordinated to the Ministry of General Machine-Building . The Soviet space program served as an important marker of claims by the Soviet Union to its superpower status. Soviet investigations into rocketry began with
28674-452: Was during the Cold War. After the ability to create nuclear weapons, the narrative of defense/offense left land and the power to control the air the focus. Both the Soviet Union and the U.S. were racing to prove their superiority in technology through exploring space. In fact, the reason NASA was created was as a response to Sputnik I. The launch of the first human-made object to orbit Earth ,
28851-405: Was first introduced in North America when Russian explorers voyaged into Alaska and claimed it for Russia during the 18th century. Although most Russian colonists left after the United States bought the land in 1867, a handful stayed and preserved the Russian language in this region to this day, although only a few elderly speakers of this unique dialect are left. In Nikolaevsk, Alaska , Russian
29028-421: Was fluent in Russian in 2006, and 19% used it as the main language with family, friends, or at work. According to the 2014 Moldovan census , Russians accounted for 4.1% of Moldova's population, 9.4% of the population declared Russian as their native language, and 14.5% said they usually spoke Russian. According to the 2010 census in Russia , Russian language skills were indicated by 138 million people (99.4% of
29205-407: Was in 1921, when the Soviet military sanctioned the commencement of a small research laboratory to explore solid fuel rockets , led by Nikolai Tikhomirov , a chemical engineer, and supported by Vladimir Artemyev , a Soviet engineer. Tikhomirov had commenced studying solid and Liquid-fueled rockets in 1894, and in 1915, he lodged a patent for "self-propelled aerial and water-surface mines." In 1928
29382-456: Was intended as a means to test the possibility of a manned mission to the moon, including methods of a stable re-entry to earth from a Lunar trajectory using a heat shield. It did not flyby the moon, but established an elliptical orbit at Lunar distance. Due to issues with the crafts orientation, it was unable to make a soft-landing in the Soviet union and instead was self destructed. Later in the year Zond 5 , carrying two Russian tortoises became
29559-430: Was killed in an endurance experiment after the chamber he was in caught on fire. The Soviet Union chose to cover up his death and continue on with the space program. Korolev died in January 1966 from complications of heart disease and severe hemorrhaging following a routine operation that uncovered colon cancer . Kerim Kerimov , who had previously served as the head of the Strategic Rocket Forces and had participated in
29736-542: Was more advanced than the Allies and a race commenced between the Soviet Union and the United States to capture and exploit the technology. Soviet rocket specialist was sent to Germany in 1945 to obtain V-2 rockets and worked with German specialists in Germany and later in the Soviet Union to understand and replicate the rocket technology. The involvement of German scientists and engineers
29913-501: Was not very interested in competing with Apollo. While the government and the Communist Party used the program's successes as propaganda tools after they occurred, systematic plans for missions based on political reasons were rare, one exception being Valentina Tereshkova , the first woman in space, on Vostok 6 in 1963. Missions were planned based on rocket availability or ad hoc reasons, rather than scientific purposes. For example,
30090-777: Was relocated to a prison for scientists and engineers in September 1940. During World War II rocketry efforts were carried out by three Soviet design bureaus . RNII continued to develop and improve solid fuel rockets, including the RS-82 and RS-132 missiles and the Katyusha rocket launcher, where Pobedonostsev and Tikhonravov continued to work on rocket design. In 1944, RNII was renamed Scientific Research Institute No 1 (NII-I) and combined with design bureau OKB-293, led by Soviet engineer Viktor Bolkhovitinov , which developed, with Aleksei Isaev , Boris Chertok , Leonid Voskresensky and Nikolay Pilyugin
30267-459: Was slow. The progress of the Apollo program alarmed the chief designers, who each advocated for his own program as the response. Multiple, overlapping designs received approval, and new proposals threatened already approved projects. Due to Korolev's "singular persistence", in August 1964—more than three years after the United States declared its intentions—the Soviet Union finally decided to compete for
30444-428: Was the chief rocket engine designer but he had a personal friction with Korolev and refused to develop the large single chamber cryogenic engines that Korolev needed to build heavy boosters. Chelomey benefited from the patronage of Khrushchev and in 1960 was given the plum job of developing a rocket to send a crewed vehicle around the Moon and a crewed military space station. With limited space experience, his development
30621-399: Was the first celestial body to be the object of space exploration. It holds the distinctions of being the first remote celestial object to be flown by, orbited, and landed upon by spacecraft, and the only remote celestial object ever to be visited by humans. In 1959, the Soviets obtained the first images of the far side of the Moon , never previously visible to humans. The U.S. exploration of
30798-435: Was the first flyby of Venus to return data (closest approach 34,773 kilometers). Pioneer 6 was the first satellite to orbit the Sun , launched on 16 December 1965. The other planets were first flown by in 1965 for Mars by Mariner 4 , 1973 for Jupiter by Pioneer 10 , 1974 for Mercury by Mariner 10 , 1979 for Saturn by Pioneer 11 , 1986 for Uranus by Voyager 2 , 1989 for Neptune by Voyager 2 . In 2015,
30975-477: Was the first to return images from the surface of another planet, returning images from Venus. In 1971, the Mars 3 mission achieved the first soft landing on Mars returning data for almost 20 seconds. Later, much longer duration surface missions were achieved, including over six years of Mars surface operation by Viking 1 from 1975 to 1982 and over two hours of transmission from the surface of Venus by Venera 13 in 1982,
31152-402: Was the sixth-most used language on the top 1,000 sites, behind English, Chinese, French, German, and Japanese. Despite leveling after 1900, especially in matters of vocabulary and phonetics, a number of dialects still exist in Russia. Some linguists divide the dialects of Russian into two primary regional groupings, "Northern" and "Southern", with Moscow lying on the zone of transition between
31329-480: Was to begin exploration of the Phobos and Martian circumterrestrial orbit, and study whether the moons of Mars, or at least Phobos, could be a "trans-shipment point" for spaceships traveling to Mars. Until the advent of space travel , objects in the asteroid belt were merely pinpricks of light in even the largest telescopes, their shapes and terrain remaining a mystery. Several asteroids have now been visited by probes,
