Although Korolev trained as an aircraft designer, his greatest strengths proved to be in design integration, organization and strategic planning. Arrested for alleged mismanagement of funds (he spent the money on unsuccessful experiments with rocket devices), he was imprisoned in 1938 for almost six years, including some months in a [[Kolyma]] labour camp. Following his release he became a recognized rocket designer and a key figure in the development of the Soviet [[Intercontinental ballistic missile]] program. He was then appointed{{by whom|date=April 2016}} to lead the [[Soviet space program]] and made a Member of [[Russian Academy of Sciences|Soviet Academy of Sciences]], overseeing the early successes of the [[Sputnik]] and [[Vostok program|Vostok]] projects including the first human Earth orbit mission by [[Yuri Gagarin|Yuri Alexeevich Gagarin]] on 12 April 1961. Korolev's unexpected death in 1966 interrupted implementation of his plans for a Soviet manned Moon landing before the United States 1969 mission.

Before his death he was officially identified only as ''Glavny Konstruktor'' (''Главный Конструктор''), or the ''Chief Designer'', to protect him from possible [[cold war]] assassination attempts by the United States.<ref name="Scott and Leonov, p. 53.">Scott and Leonov, p. 53. Harford, p. 135.</ref> Only following his death in 1966 has he received appropriate public recognition as the driving force behind Soviet accomplishments in space exploration during and following the [[International Geophysical Year]].

==Early life==
[[File:Sergey Korolyov boy 1912.jpg|thumb|right|upright|Sergei Korolev as a boy in 1912.]]

Korolev was born in [[Zhytomyr]], the capital of [[Volhynian Governorate]] of the [[Russian Empire]] now recognized as part of [[Ukraine]]. His father, Pavel Yakovlevich Korolev, was from the Belarusian city of [[Mogilev]];<ref>http://www.famhist.ru/famhist/korol/001905fe.htm</ref> and his mother, Maria Nikolaevna Koroleva (Moskalenko/Bulanina), was a daughter of a wealthy merchant in the Ukrainian city of [[Nezhin]].<ref>http://astrokras.narod.ru/pub/korolev-1.htm</ref> His father moved to Zhytomyr to be a teacher of the [[Russian language]].<ref>[http://zhzh.info/news/2007-01-12-761 В Житомире сто лет назад появился на свет Сергей Королев. ФОТО / Культура / Журнал Житомира / Zhitomir City Journal]. Zhzh.info (12 January 2007). Retrieved on 2011-04-30.</ref> Three years after his birth the couple separated due to financial difficulties. Although Pavel later wrote to Maria requesting a meeting with his son, Sergei was informed by his mother that his father had died. Sergei never saw his father after the family break-up, and Pavel died in 1929 before his son learned the truth.

Korolev grew up in Nezhin, under the care of his maternal grandparents Mykola Yakovych Moskalenko who was a trader of the Second Guild and Maria Matviivna Moskalenko (Fursa), a daughter of a local [[cossack]]. Korolev's mother also had a sister Anna and two brothers Yuri and Vasily. Maria Koroleva was frequently away attending Women's higher education courses in [[Kiev]]. As a child, Korolev was stubborn, persistent, and argumentative. Sergei grew up a lonely child with few friends. Korolev began reading at an early age, and his abilities in [[mathematics]] and other subjects made him a favorite student of his teachers, but caused jealousy from his peers. He later stated in an interview, the torment of classmates bullying and teasing him as a small child encouraged his focus on academic work.<ref name="Harford, James 1999">Harford, James. Korolev: How One Man Masterminded the Soviet Drive to Beat America to the Moon. New York: Wiley, 1999. Print.</ref> His mother divorced Pavel in 1915 and in 1916 married Grigory Mikhailovich Balanin, an electrical engineer educated in Germany but attending the Kiev Polytechnic University because German engineering diplomas were unrecognized in Russia. After getting a job with the regional railway, Grigory moved the family to [[Odessa]] in 1917, where they endured hardships with many other families through the tumultuous years following the [[Russian Revolution of 1917|Russian Revolution]] and continuing internecine struggles until the [[Bolsheviks]] assumed unchallenged power in 1920. Local schools were closed and young Korolev had to continue his studies at home. Grigory proved a good influence on his step-son, who suffered from a bout of [[typhus]] during the severe food shortages of 1919.

==Education==
[[File:Молодой Королёв.jpg|thumb|right|upright|Sergei Korolev in the 1920s.]]

Korolev received vocational training in [[carpentry]] and in various academics at the Odessa Building Trades School (Stroyprofshkola No. 1). Enjoyment of a 1913 air show inspired interest in [[aeronautical engineering]]. Korolev began designing a [[glider (aircraft)|glider]] as a diversion while studying for his graduation exams at the vocational school. He made an independent study of flight theory, and worked in the local glider club. A detachment of military seaplanes had been stationed in Odessa, and Korolev took a keen interest in their operations.

In 1923 he joined the Society of Aviation and Aerial Navigation of Ukraine and the Crimea (OAVUK). He had his first flying lesson after joining the Odessa hydroplane squadron and had many opportunities to fly as a passenger. In 1924 he personally designed an OAVUK construction project glider called the K-5. He briefly trained in gymnastics until his academic work suffered from this distraction. Korolev hoped to attend the Zhukovsky Academy in [[Moscow]], but his qualifications did not meet the academy's standards.<ref name="Harford, James 1999"/> He attended the [[Kiev Polytechnic Institute]]'s aviation branch in 1924 while living with his uncle Yuri, and earning money to pay for his courses by performing odd jobs. His curriculum was technically oriented, and included various engineering, physics and mathematics classes. He met and became attracted to a classmate, Xenia Vincentini, who would later become his first wife.<ref name="Harford, James 1999"/>  In 1925 he was accepted into a limited class on glider construction, and suffered two broken ribs flying the training glider they built. He continued courses at Kiev until he was accepted into the [[Bauman Moscow State Technical University]] (MVTU, BMSTU) in July 1926.

Korolev studied specialized aviation topics until 1929, while living with his family in the typically crowded conditions of Moscow. Korolev enjoyed opportunities to fly gliders and powered aircraft during this part of his education. He designed a glider in 1928, and flew it in a competition the next year. The Communist Party accelerated the education of engineers in 1929 to meet the country's urgent need for their skills. Korolev obtained a diploma by producing a practical aircraft design by the end of the year. His advisor was the famous [[Andrei Tupolev]].

==Early career==
[[File:Korolyov in cockpit.jpg|thumb|right|Korolev sitting in the cockpit of glider "Koktebel."]]
[[File:Sergey Korolyov.jpg|thumb|upright|Sergey Korolyov in [[comdiv]] uniform (1933).]]
After graduation, Korolev worked with some of the best Soviet designers at the 4th Experimental Section aircraft design bureau OPO-4 headed by {{Interlanguage link multi|Paul Aimé Richard|fr|3=Paul Aimé Richard|vertical-align=sup}} who emigrated to the USSR from [[France]] in the 1920s.<ref>{{Cite book|last = Siddiqi|first = Asif A.|title = The red rockets' glare.

In 1930 he became interested in the possibilities of liquid-fueled rocket engines to propel airplanes while working as a lead engineer on the [[Tupolev TB-3]] heavy bomber. Korolev earned his pilot's license in 1930 and explored the operational limits of the aircraft he piloted, wondering what was beyond his plane's altitude limit and how he could get there. Many believe this was the start of his interest in space.<ref name="Harford, James 1999"/>

Korolev married Xenia Vincentini on 6 August 1931. He had first proposed marriage to her in 1924, but she then declined so she might continue her higher education. In 1931, Korolev and [[Spaceflight|space travel]] enthusiast [[Friedrich Zander]] participated in the creation of the [[Group for the Study of Reactive Motion]] (GIRD), one of the earliest state-sponsored centers for rocket development in the USSR. In May 1932 Korolev was appointed chief of the group; and military interest encouraged funding of group projects. GIRD developed three different propulsion systems, each more successful than the last. Their first launch of a liquid-fueled rocket was GIRD-X in 1933. (Although this is often cited as the GIRD-09, the hybrid GIRD-09 used solid gasoline and liquid oxygen.<ref>{{cite book|last=Altman and Holzman|title=Progress in Astronautics and Aeronautics, vol. 218: Fundamentals of Hybrid Rocket Propulsion|year=2007|publisher=American Institute of Aeronautics and Astronautics|location=Reston, VA|page=5|editor1=Martin J. Chiaverini |editor2=Kenneth K. Kuo |chapter=1, Overview and History of Hybrid Rocket Propulsion }}</ref>) This was just seventeen years after [[Ivan Grave|Colonel Ivan Platonovich Grave]]'s first launch in 1916 (patent in 1924).

Growing military interest in this new technology caused GIRD to be merged with the Gas Dynamics Laboratory (GDL) at [[Saint Petersburg|Leningrad]] in 1933 to create the Jet Propulsion Research Institute (RNII), headed up by the military engineer Ivan Kleimenov and containing a number of enthusiastic proponents of space travel, including [[Valentin Glushko]]. Korolev became the Deputy Chief of the institute, where he supervised development of [[cruise missile]]s and a manned rocket-powered [[Glider aircraft|glider]]. "Rocket Flight in Stratosphere" was published by Korolev in 1934.

On 10 April 1935, Korolev's wife gave birth to their daughter, Natalya; and they moved out of Sergei's parents' home and into their own apartment in 1936. Both Korolev and his wife had careers, and Sergei always spent long hours at his design office. By now he was chief engineer at RNII. The RNII team continued their development work on rocketry, with particular focus on the area of stability and control. They developed automated [[gyroscope]] stabilization systems that allowed stable flight along a programmed trajectory. Korolev was a charismatic leader who served primarily as an engineering project manager. He was a demanding, hard-working man, with a disciplinary style of management. Korolev personally monitored all key stages of the programs and paid meticulous attention to detail.

==Imprisonment==
[[File:Korolev posle aresta 1938.jpg|thumb|right|Sergei Korolev shortly after his arrest, 1938]]
[[File:Bw1940-02-29-KorolevSP.jpg|thumb|Sergei Korolev, 1940]]
Korolev was arrested by the [[NKVD]] on 22 June 1938 after being accused of deliberately slowing the work of the research institute by [[Ivan Kleymenov]], [[Georgy Langemak]], and [[Valentin Glushko]].<ref name=SilentSea110>{{cite book|first1=Francis|last1=French |first2=Colin|last2=Burgess|title=Into That Silent Sea: Trailblazers of the Space Era, 1961-196|page=110|year=2007|publisher=University of Nebraska Press|isbn=9780803206977|url=https://books.google.co.uk/books?id=VykZgN3hZyoC&pg=PA110&lpg=PA110&dq=Korolev+was+arrested+by+the+NKVD&source=bl&ots=w3SFtwAzof&sig=qMNdntd6ONpMS9IU2ywPGbvIs-8&hl=en&sa=X&ved=0ahUKEwiNkbzNicDSAhULKsAKHSXTDUIQ6AEIODAE#v=onepage&q=Korolev%20was%20arrested%20by%20the%20NKVD&f=false}}</ref> He was tortured in the [[Lubyanka Building|Lubyanka]] prison to extract a confession during the [[Great Purge]], and was tried and sentenced to death as the purge was waning.<ref name=face2face>[https://web.archive.org/web/20140407044816/http://balanga.tv:80/film/596/ Korolev vs Von Braun: The Space Race]</ref> Kleymenov and Langemak were executed,<ref name=armaments>{{cite book|title=Soviet armaments industry.|year=1993|publisher=Harwood Academic|location=Chur|isbn=3-7186-5313-3|url=https://books.google.com/books?id=Ygg66pf52OsC&lpg=PA76&dq=Chyeranovskiy&pg=PA76#v=onepage&q=Chyeranovskiy&f=false}} {{Page needed|date=March 2017}}</ref> but Korolev survived. Glushko and Korolev had reportedly been denounced by [[Andrei Kostikov]], who became the head of RNII after its leadership was arrested. The rocket program was set back for years and fell far behind the rapid progress taking place in Germany. Kostikov was ousted a few years later over accusations of budget irregularities.{{citation needed|date=September 2014}}

Korolev was sent to prison, where he wrote many appeals to the authorities, including Stalin himself. Following the fall of NKVD head [[Nikolai Yezhov]], the new chief [[Lavrenti Beria]] chose to retry Korolev on reduced charges in 1939; but by that time Korolev was on his way from prison to a [[gulag]] camp in the far east of Siberia, where he spent several months in a gold mine in the [[Kolyma]] area before word reached him of his retrial. Work camp conditions of inadequate food, shelter, and clothing killed thousands of prisoners each month.<ref name="Harford, James 1999"/>  Korolev sustained injuries and lost most of his teeth from [[scurvy]] before being returned to Moscow in late 1939.<ref name=face2face/> When he reached Moscow, Korolev's sentence was reduced to eight years<ref>{{cite book|last = French|first = Francis|author2=Colin Burgess |author3=Paul Haney |title = Into that Silent Sea: Trailblazers of the Space Era, 1961–1965|publisher = University of Nebraska Press|page = 110|isbn = 0-8032-1146-5}}</ref> to be served in a ''[[sharashka]]'' penitentiary for intellectuals and the educated. These were effectively slave-labor camps where scientists and engineers worked on projects assigned by the Communist party leadership. The ''Central Design Bureau 29'' (CKB-29, ЦКБ-29) of the NKVD, served as Tupolev's engineering facility, and Korolev was brought here to work for his old mentor. During [[World War II]], this ''sharashka'' designed both the [[Tupolev Tu-2]] bomber and the [[Petlyakov Pe-2]] dive bomber. The group was moved several times during the war, the first time to avoid capture by advancing German forces. Korolev was moved in 1942 to the ''sharashka'' of [[Kazan]] [[d:Q4207853|OKB-16]] under Glushko. Korolev and Glushko designed [[rocket-assisted take off]] boosters for aircraft and the RD-1&nbsp;kHz<ref>"''Last of the Wartime Lavochkins''", AIR International, Bromley, Kent, U.K., November 1976, Volume 11, Number 5, pages 245–246.</ref> auxiliary rocket motor tested in an unsuccessful fast-climb [[Lavochkin La-7R]]. Korolev was isolated from his family until 27 June 1944 when he – along with Tupolev, Glushko and others – was finally discharged by special government decree, although the charges against him were not dropped until 1957.<ref>{{cite book|last = Parrish|first = Michael|title = The Lesser Terror|publisher = Greenwood Publishing Group|year = 1996|page = 46|isbn = 0-275-95113-8}}</ref>

Korolev rarely talked about his experience in the gulag. He lived under constant fear of being executed for the military secrets he possessed, and was deeply affected by his time in the camp, becoming reserved and cautious. He later learned Glushko was one of his accusers and this may have been the cause of the lifelong animosity between the two men. The design bureau was handed over from NKVD control to the government's aviation industry commission. Korolev continued working with the bureau for another year, serving as deputy designer under Glushko and studying various rocket designs.

==Ballistic missiles==
{{Refimprove section|date=June 2008}}

Korolev was commissioned into the [[Red Army]] with the rank of [[polkovnik|colonel]] in 1945; his first decoration was the Badge of Honor, awarded in 1945 for his work on the development of rocket motors for military aircraft. He was among the experts flown to Germany to recover the technology of the German [[V-2 rocket]]. The Soviets placed a priority on reproducing lost documentation on the V-2, and studying the various parts and captured manufacturing facilities. That work continued in [[East Germany]] until late 1946, when 2,000+ German scientists and engineers were sent to Russia through [[Operation Osoaviakhim]]. Most of the German experts, [[Helmut Gröttrup]] being an exception, were engineers and technicians involved in wartime mass-production of V-2, and they had not worked directly with [[Wernher von Braun]]. Many of the leading German rocket scientists, including Dr. von Braun himself, surrendered to Americans and were transported to the United States as part of [[Operation Paperclip]].

Stalin made rocket and missile development a national priority, and a new [[NII-88]] institute was created for that purpose in the suburbs of Moscow.  Korolev's team oversaw 170+ German specialists - including [[Helmut Gröttrup]] and [[Fritz Karl Preikschat]] - in Branch 1 of NII-88 on [[Gorodomlya Island]] in [[Lake Seliger]] some {{convert|200|km}} from Moscow. Their facility was surrounded by barbed wire and armed guards with watch-dogs, although [[Boris Chertok]], chief designer of guidance and control systems, notes in his book ''Rockets and People'',
<blockquote>
All structures on Gorodomlya island were renovated and living conditions were quite decent for those times. At least married specialists received separate two- or three-room apartments. Visiting the island, I could only envy them, because I and my family lived in Moscow in a shared four-room apartment, where we had two rooms of {{convert|24|m2}} combined. Many of our specialists and workers lived in barracks without most elementary necessities. [...] This is why life on the island behind barbed wire could not compare at all to prisoner of war conditions.<ref name="ReferenceA">Черток Б.Е., Ракеты и люди (Boris Chertok, Rockets and People)</ref>
</blockquote>

Development of [[ballistic missile]]s was put under the military control of [[Dmitriy Ustinov]], with Korolev serving as a chief designer of long-range missiles at the Special Design Bureau 1 ([[OKB-1]]) of NII-88. Korolev demonstrated his organizational abilities in this new facility by keeping a dysfunctional and highly compartmentalized organization operating.<ref name=RedMoon>{{cite book|author=Brzezinski, Matthew|title=Red Moon Rising.|year=2007|publisher=Times Books|location=New York|isbn=0-8050-8147-X}}</ref>

With blueprints produced from disassembled V-2 rockets, the team began producing a working replica of the rocket. This was designated the [[R-1 rocket|R-1]], and was first tested in October 1947. A total of eleven were launched with five hitting the target. This was similar to the German hit ratio, and demonstrated the unreliability of the V-2. In 1947, Korolev's group began working on more advanced designs, with improvements in range and throw weight. The [[R-2 rocket|R-2]] doubled the range of the V-2, and was the first design to utilize a separate warhead. This was followed by the R-3, which had a range of {{convert|3,000|km}}, and thus could target England. The Soviets continued to utilize the expertise of the Germans on V-2 technology for some time; but, to preserve secrecy surrounding the ballistic missile program, Gröttrup and his team had no access to classified work of their Russian colleagues on new rocket technology including production and testing facilities. This negatively affected the morale of the German team and limited their technical contributions. The Ministry of Defence decided to dissolve the German team in 1950 and [[repatriate]]d the German engineers and their families between December 1951 and November 1953.<ref name="ReferenceA"/>

Glushko couldn't obtain the required thrust from the  R-3 engines, so the project was canceled in 1952; and Korolev joined the Soviet [[Communist Party]] that year to request money from the government for future projects including the [[R-5 missile|R-5]], with a more modest {{convert|1,200|km}} range. It completed a first successful flight by 1953. The world's first true [[intercontinental ballistic missile]] (ICBM) was the [[R-7 Semyorka]]. This was a two-stage rocket with a maximum payload of 5.4 tons, sufficient to carry the Soviets' bulky [[Nuclear weapon|nuclear bomb]] an impressive distance of {{convert|7000|km}}. After several test failures, the R-7 successfully launched on August 1957, sending a dummy payload to the [[Kamchatka Peninsula]]. On 19 April 1957 Korolev was declared fully "[[Rehabilitation (Soviet)|rehabilitated]]", as the government acknowledged that his sentence was unjust.

==Space program==
{{Unreferenced section|date=June 2008}}

Korolev was keenly aware of the orbital possibilities of the rockets being designed as ICBMs. He conceptualized using the R-7 to launch [[Sputnik]] as early as 1953, and suggested to the [[Russian Academy of Sciences|Academy of Sciences of the USSR]] the concept for sending a dog into space. The Communist Party was uninterested until the United States press began discussing a possible satellite launch for the International Geophysical year. While the US government debated the idea of spending millions of dollars on this concept. Korolev's group suggested the international prestige of launching a satellite before the United States could act. The spirit of cold war competition was adequate to secure approval for the project.

The satellite was designed and constructed in less than a month. [[Sputnik 1]] was a simple polished metal sphere containing batteries powering a transmitter using external antennae. Korolev personally managed the assembly at a hectic pace; and the satellite was placed in orbit on 4 October 1957 using a rocket that had successfully launched only once before. International response to the accomplishment was electrifying, and political ramifications continued for decades. [[Nikita Khrushchev]] was pleased with this success, and encouraged launch of a more sophisticated satellite less than a month later in time for the 40th anniversary of the [[October Revolution]] on 3 November.

This new [[Sputnik 2]] spacecraft had six times the mass of the Sputnik 1, and carried the dog [[Laika]] as a payload. The entire vehicle was designed from scratch within four weeks, with no time for testing or quality checks. It was successfully launched on 3 November and Laika was placed in orbit. There was no mechanism to bring the dog back to Earth, which died from heat exhaustion after five or six hours in space.<ref>[http://www.russianspaceweb.com/sputnik2_mission.html "Sputnik-2 in orbit", ''Russian Space Web'']</ref>

The instrument-laden [[Sputnik 3]] spacecraft was sent into orbit on 15 May 1958. The tape recorder that was to store the data failed after launch. As a result, the discovery and mapping of the [[Van Allen radiation belt]]s were left to the United States' [[Explorer 3]] and [[Pioneer 3]] satellites. Sputnik 3 left little doubt with the American government about the Soviets' pending ICBM capability.

===The Moon===
{{Main|Soviet Moonshot}}
Korolev then turned his attention to reaching the [[Moon]]. A modified version of the R-7 launch vehicle was used with a new upper stage. The engine for this final stage was the first designed to be fired in outer space. The first three lunar probes launched in 1958 all failed in part because of political pressure forcing the launches to be rushed with an inadequate budget to test and develop the hardware properly before they were ready to fly. Korolev thought political infighting in Moscow was responsible for the lack of sufficient funding for the program, although the US space program at this early phase also had a scarcely enviable launch record. Once, when pressured to beat the US to a working lunar probe, Korolev allegedly exclaimed "Do you think that only American rockets explode!?"<ref name="Harford, James 1999"/> The [[Luna 1]] mission in 1959 was intended to impact the surface, but missed by about {{convert|6000|km}}. Nevertheless, this probe became the first to reach escape velocity and the first to go near the Moon. A subsequent attempt ([[Luna E-1A No.1]]) failed at launch, and then [[Luna 2]] successfully impacted the surface on 14 September 1959, giving the Soviets another first. This was followed just one month later by an even greater success with [[Luna 3]]. It was launched only two years after Sputnik 1, and on 7 October 1959 was the first spacecraft to photograph the [[Far side (Moon)|far side of the Moon]].

Korolev's group was also working on ambitious programs for missions to [[Mars]] and [[Venus]], putting a man in orbit, launching communication, spy and weather satellites, and making a soft-landing on the Moon. A radio communication center needed to be built in the [[Crimea]], near [[Simferopol]] and near [[Pluton (complex)|Evpatoria]] to control the spacecraft. Many of these projects were not realized in his lifetime, and none of the planetary probes performed a completely successful mission until after his death.

===Human spaceflight===

Korolev's planning for the piloted mission began in 1958 with design studies for the future [[Vostok spacecraft]]. It was to hold a single passenger in a [[space suit]], and be fully automated. The capsule had an escape mechanism for problems prior to launch, and a soft-landing and ejection system during the recovery.

On 15 May 1960 an unmanned prototype performed 64 orbits of the Earth, but the reentry maneuver failed. Four tests were then sent into orbit carrying dogs, and the last two were fully successful. After gaining approval from the government, a modified version of the R-7 was used to launch [[Yuri Gagarin|Yuri Alexeevich Gagarin]] into orbit on 12 April 1961. The first human in space and Earth orbit returned to Earth via a parachute after ejecting at an altitude of {{convert|7|km|ft}}. Gagarin was followed by additional Vostok flights, culminating with 81 orbits completed by [[Vostok 5]] and the launch of [[Valentina Tereshkova]] as the first woman cosmonaut in space aboard [[Vostok 6]].

Korolev proposed communications satellites and a modified Vostok useful for photographic reconnaissance to quiet Soviet military objections about the cost of planetary and manned programs of no perceived value for national defense. Korolev planned to move forward with [[Soyuz spacecraft|Soyuz]] craft able to dock with other craft in orbit and exchange crews. He was directed by Khrushchev to cheaply produce more 'firsts' for the piloted program, including a multi-manned flight. Korolev was reported to have resisted the idea as the Vostok was a one-man spacecraft and the three-man Soyuz was several years away from being able to fly. Khrushchev was not interested in technical excuses and let it be known that if Korolev could not do it, he would give the work to his rival, [[Vladimir Chelomei]].

Cosmonaut [[Alexey Leonov]] describes the authority Korolev commanded at this time.<ref name="Scott and Leonov, p. 53."/>
<blockquote>
Long before we met him, one man dominated much of our conversation in the early days of our training;
Sergei Pavlovich Korolev, the mastermind behind the Soviet space program.
He was only ever referred to by the initials of his first two names, SP, or
by the mysterious title of "Chief Designer", or simply "Chief".
For those on the space program there was no authority higher.
Korolev had the reputation of being a man of the highest integrity,
but also of being extremely demanding.
Everyone around him was on tenterhooks, afraid of making a wrong move and
invoking his wrath. He was treated like a god.
</blockquote>
Leonov recalls the first meeting between Korolev and the cosmonauts.<ref>Scott and Leonov, p. 54.</ref>
<blockquote>
I was looking out of the window when he arrived, stepping out of a black [[ZIS-110|Zis 110]] limousine.
He was taller than average;
I could not see his face, but he had a short neck and large head.
He wore the collar of his dark-blue overcoat turned up and the brim of his hat pulled down.
</blockquote>
<blockquote>
"Sit down, my little eagles," he said as he strode into the room where we were waiting.
He glanced down a list of our names and
called on us in alphabetical order to introduce ourselves briefly and
talk about our flying careers.
</blockquote>

{{Main article|Voskhod program}}

The [[Voskhod spacecraft|Voskhod]] was designed as an incremental improvement on the Vostok to meet Khruschev's goal. One of the difficulties in the design of the Voskhod was the need to land it via parachute. The three-person crew could not bail out and land by parachute, since the altitude would not be survivable. So the craft would need much larger parachutes in order to land safely. Early tests with the craft resulted in some failures causing the death of test animals until use of stronger fabric improved parachute reliability.

The resulting Voskhod was a stripped-down vehicle from which any excess weight had been removed; although a backup retrofire engine was added, since the more powerful [[Voskhod rocket]] used to launch the craft would send it to a higher orbit than the Vostok, eliminating the possibility of a natural decay of the orbit and reentry in case of primary retrorocket failure. After one unmanned test flight, this spacecraft carried a crew of three [[cosmonauts]], Komarov, Yegorov and Feoktistov, into space on 12 October 1964 and completed sixteen orbits. This craft was designed to perform a soft landing, eliminating a need for the ejection system; but the crew was sent into orbit without space suits or a launch abort system.

With the Americans planning a space walk with their [[Gemini program]], the Soviets decided to trump them again by performing a space walk on the second Voskhod launch. After rapidly adding an airlock, the [[Voskhod 2]] was launched on 18 March 1965, and [[Alexei Leonov]] performed the world's first space walk. The flight very nearly ended in disaster and plans for further Voskhod missions were shelved. In the meantime the change of Soviet leadership with the fall of Khrushchev meant that Korolev was back in favor and given charge of beating the US to landing a man on the Moon.

For the [[Soviet Moonshot#Moon landing N1/L3 program|Moon race]], Korolev's staff started to design the immense [[N1 rocket]] in 1961,<ref name="sovlun">Lindroos, Marcus.

As well, Korolev was designing the Luna series of vehicles that would soft-land on the Moon and make robotic missions to Mars and Venus. Unexpectedly, he died in January 1966, before he could see his various plans brought to fruition.

====Criticism====

Engineer [[Sergei Khrushchev]], son of former Soviet Premier Nikita Khrushchev, explained in an interview some shortcomings of Korolev's approach, which in his opinion is why the Soviets didn’t land on the moon:

:The Russian people had many problems in day-to-day life, they were not too concerned about the first man on the moon.

:'''Was Russia pretty close?'''
:The Russians were not pretty close. I think Russia had no chance to be ahead of the Americans under Sergei Korolev and his successor, Vasili Mishin. Korolev was not a scientist, not a designer: he was a brilliant manager. Korolev's problem was his mentality. His intent was to somehow use the launcher he had [the [[N1 (rocket)]]]. It was designed in 1958 for a different purpose and with a limited payload of about 70 tons. His philosophy was, let’s not work by stages [as is usual in spacecraft design], but let’s assemble everything and then try it. And at last it will work. There were several attempts and failures with Lunnik [a series of unmanned Soviet moon probes]. Sending man to the moon is too complicated, too complex for such an approach. I think it was doomed from the very beginning.<ref>Saswato R.

==Death==
[[File:Korolyev kremlin wall.jpg|thumb|right|Korolev's tomb (left) in the [[Kremlin Wall Necropolis]]]]

On 3 December 1960, Korolev suffered his first [[myocardial infarction|heart attack]]. During his convalescence, it was also discovered that he was suffering from a kidney disorder, a condition brought on by his detention in the Soviet prison camps. He was warned by the doctors that if he continued to work as intensely as he had, he would not live long. Korolev became convinced that Khrushchev was only interested in the space program for its propaganda value and feared that he would cancel it entirely if the Soviets started losing their leadership to the United States, so he continued to push himself even harder.

By 1962 Sergei Korolev's health problems were beginning to accumulate and he was suffering from numerous ailments. He had a bout of intestinal bleeding that led to him being taken to the hospital in an ambulance. In 1964 doctors diagnosed him with [[cardiac arrhythmia]]. In February he spent ten days in the hospital after a heart problem. Shortly after he was suffering from inflammation of his [[gallbladder]]. The mounting pressure of his workload was also taking a heavy toll, and he was suffering from a lot of fatigue. Korolev was also experiencing hearing loss, possibly from repeated exposure to loud rocket engine tests.

The actual circumstances of Korolev's death remain somewhat uncertain. In December 1965, he was supposedly diagnosed with a bleeding [[polyp (medicine)|polyp]] in his [[large intestine]]. He entered the hospital on 5 January 1966 for somewhat routine surgery, but died nine days later. It was stated by the government that he had what turned out to be a large, cancerous [[tumor]] in his abdomen, but Glushko later reported that he actually died due to a poorly performed operation for [[hemorrhoid]]s. Another version states that the operation was going well and no one was predicting any complications. Suddenly, during the operation, Korolev started to bleed. Doctors tried to provide [[intubation]] to allow him to breathe freely, but his jaws, injured during his time in a gulag, had not healed properly and impeded the installation of the breathing tube. Korolev died without regaining consciousness. According to Harford, Korolev's family confirmed the cancer story.  His weak heart contributed to his death during surgery.<ref>McKie, Robin, "[https://www.theguardian.com/science/2011/mar/13/yuri-gagarin-first-space-korolev Sergei Korolev: the rocket genius behind Yuri Gagarin]", ''[[The Observer]]'', 13 March 2011, retrieved 21 March 2011.</ref>

Under a policy initiated by Stalin and continued by his successors, the identity of Korolev was not revealed until after his death. The purported reason was to protect him from foreign agents from the United States. As a result, the Soviet people didn't become aware of his accomplishments until after his death. His [[obituary]] was published in the ''[[Pravda]]'' newspaper on 16 January 1966, showing a photograph of Korolev with all his medals. Korolev's ashes were interred with state honors in the [[Kremlin Wall Necropolis|Kremlin Wall]].

Korolev is often compared to [[Wernher von Braun]] as the leading architect of the [[Space Race]]. Like von Braun, Korolev had to compete continually with rivals, such as [[Vladimir Chelomei]], who had their own plans for flights to the Moon. Unlike the Americans, he also had to work with technology that in many aspects was less advanced than what was available in the United States, particularly in electronics and computers, and to cope with extreme political pressure.

Korolev's successor in the Soviet space program was [[Vasily Mishin]], a quite competent engineer who had served as his deputy and right-hand man. After Korolev died, Mishin became the Chief Designer, and he inherited what turned out to be a flawed [[N1 rocket]] program. In 1972, Mishin was fired and then replaced by a rival, [[Valentin Glushko]], after all four N-1 test launches failed. By that time, the rival Americans had already made it to the Moon, and so the program was canceled by CPSU General Secretary [[Leonid Brezhnev]].

==Personal life==
The Soviet émigré Leonid Vladimirov related the following description of Korolev by Glushko at about this time:

:"Short of stature, heavily built, with head sitting awkwardly on his body, with brown eyes glistening with intelligence, he was a skeptic, a cynic and a pessimist who took the gloomiest view of the future. 'We are all going to be [[Execution by shooting|whacked]] and there will be no [[obituary]]' (''Khlopnut bez nekrologa'', Хлопнут без некролога – i.e. "we will all vanish without a trace") was his favorite expression."<ref>Kerber, Lev. [http://www.lib.ru/MEMUARY/KERBER/tupolewskaya_sharaga.txt Tupolev's Sharaga] — 1973 (in Russian).</ref>

Korolev was rarely known to drink vodka or other alcoholic beverages, and chose to live a fairly austere lifestyle. He remained a handsome and solidly built man, and he was as fond of women as they were of him.

His career also contributed to instability in his personal life. About 1946, the marriage of Korolev and Vincentini began to break up. Vincentini was heavily occupied with her own career, and about this time Korolev had an affair with a younger woman named Nina Ivanovna Kotenkova, who was an English interpreter in the Podlipki office.<ref name="Harford, James 1999"/> Vincentini, who still loved Korolev and was angry over the infidelity, divorced him in 1948. Korolev and Kotenkova were married in 1949, but he is known to have had affairs even after this second marriage.

As a leader, Korolev’s passion for his work in the long term was something that made him a great one.  He was committed to training younger engineers to move into his space and missile projects, even with his own work being consuming.  Korolev knew that students would be the future of space exploration, which is why he made such an effort to communicate with them.<ref name="Harford, James 1999"/>

==Awards and honours==
[[File:The Soviet Union 1969 CPA 3731 stamp (Sergei Korolev).jpg|thumb|Sergey Korolev on a [[Postage stamps and postal history of Russia|1969 Soviet stamp]] (10 kopeks)]]
Among his awards, Korolev was twice honored as [[Hero of Socialist Labor]], in 1956 and 1961. He was also a [[Lenin Prize]] winner in 1971,<ref name="nmspacemuseum.org">[http://www.nmspacemuseum.org/halloffame/detail.php?id=15 International Space Hall of Fame :: New Mexico Museum of Space History  :: Inductee Profile] nmspacemuseum.org</ref> and was awarded the [[Order of Lenin]] three times, the [[Order of the Badge of Honour]] and the [[Medal "For Labour Valour"]].

In 1958 he was elected to the [[Academy of Sciences of the USSR]]. In 1969 and 1986, the USSR issued 10 [[Ruble|kopek]] postage stamps honoring Korolev.<ref>[[:Image:Soviet Union-1969-Stamp-0.10. Sergei Korolev.jpg|Image of 1969, 10k stamp.]] [http://www.stamprussia.com/5713b.jpg Image of 1986, 10k stamp.]</ref> In addition he was made an [[Honorary Citizen]] of [[Korolyov, Moscow Oblast|Korolyov]] and received the [[Medal "In Commemoration of the 800th Anniversary of Moscow"]].

Sergei Khrushchev claimed that the [[Nobel Prize]] committee attempted to award Korolev but the award was turned down by Khrushchev in order to maintain harmony within the Council of Chief Designers.<ref name="airspacemag.com">[http://www.airspacemag.com/space-exploration/sputchev.html Air and Space Magazine] airspacemag.com</ref>

===Namesakes===
A street in Moscow was named after Korolev in 1966 and is now called ''Ulitsa Akademika Korolyova'' (Academician Korolyov Street). ''The memorial home-museum of akademician S.P.Korolyov'' was established in 1975 in the house where Korolev lived from 1959 till 1966 ([[Moscow]], 6th Ostankinsky Lane,2/28).<ref>{{cite web|url=http://www.museum.ru/kosmonav/Housee.htm |title=The memorial home-museum of akademician S.P.Korolev |accessdate=2005-02-06 |deadurl=bot: unknown |archiveurl=https://web.archive.org/web/20050313223527/http://www.museum.ru/kosmonav/Housee.htm |archivedate=13 March 2005 |df=dmy }}</ref> In 1976 he was inducted into the ''[[New Mexico Museum of Space History|International Space Hall of Fame]]''.<ref name="nmspacemuseum.org"/>

The town of Kaliningrad (formerly ''Podlipki'', Moscow region) is the home of [[S.P. Korolev Rocket and Space Corporation Energia|RSC Energia]], the largest space company in Russia. In 1996, [[Boris Yeltsin]] renamed the town to [[Korolev, Moscow Oblast|Korolyov]]. There is now an oversized statue of S.P. Korolev located in the town square. RSC Energia was also renamed to [[S.P. Korolev Rocket and Space Corporation Energia]].

[[Astronomical naming conventions|Astronomical features named]] after Korolev include the crater [[Korolev (lunar crater)|Korolev]] on the [[Far side (Moon)|far side]] of the Moon, a [[Korolev Crater|crater]] on [[Mars]], and the [[asteroid]] [[1855 Korolyov]].

Quite a large number of streets exist with his name in Russia as well as in [[Ukraine]]. In [[Zhytomyr]] on the other side of the street (vulytsia Dmytrivska) from the house where Sergei Korolev was born is the {{Interlanguage link multi|Korolev Memorial Astronautical Museum|WD=Q26988112}}.

==Portrayals in fiction==
The first portrayal of Korolev in Soviet cinema was made in the 1972 film ''[[Taming of the Fire]]'', in which Korolev was played by renowned Russian actor [[Kirill Lavrov]]. He was played by [[Steve Nicolson]] in the 2005 [[BBC]] co-produced docu-drama ''[[Space Race (TV series)|Space Race]]''. In 2011 the British writer [[Rona Munro]] produced the play ''Little Eagles'' on Korolev's life – its premiere was from 16 April to 7 May 2011, in an [[Royal Shakespeare Company|RSC]] production at the [[Hampstead Theatre]],<ref>[http://www.hampsteadtheatre.com/page/3031/Little+Eagles/231 What's On Main Stage].
