Rocket teams assembled

The German rocket center at Peenemünde was located in the eastern part of Germany, which became the Soviet zone of occupation. On Stalin's orders, the Soviet Union sent its best rocket engineers to this region to see what they could salvage for future weapons systems. The Soviet rocket engineers were led by Sergei Korolev.

 (1947–1991) developed between two former allies, the Soviet Union and the United States, soon after the end of the Second World War. It involved a continuing state of political conflict, military tension, proxy wars, and economic competition, primarily between the Soviet Union and its satellite states, and the powers of the Western world, particularly the United States. Although the primary participants' military forces never clashed directly, they expressed this conflict through military coalitions, strategic conventional force deployments, extensive aid to states deemed vulnerable, proxy wars, espionage, propaganda, a nuclear arms race, and economic and technological competitions, such as the Space Race.

) that were capable of delivering nuclear payloads.

For its part, the Soviet Union harbored fears of invasion. Having suffered at least 27 million casualties during World War II after being invaded by Nazi Germany in 1941, the Soviet Union was wary of its former ally, the United States, which until late 1949 was the sole possessor of atomic weapons. The United States had used these weapons operationally during World War II, and it could use them again against the Soviet Union, laying waste its cities and military centers. Since the Americans had a much larger air force than the Soviet Union, and the United States maintained advance air bases near Soviet territory, in 1947 Stalin ordered the development of intercontinental ballistic missile

 rocket, which represented a major advance from the German design. Although some of its components (notably boosters) still resembled the German G-4, the new rocket incorporated staged design, a completely new control system, and a new fuel. It was successfully tested on 21 August 1957 and became the world's first fully operational ICBM the following month. It would later be used to launch the first satellite into space, and derivatives would launch all piloted Soviet spacecraft.

The United States had multiple rocket programs divided among the different branches of the American armed services, which meant that each force developed its own ICBM program. The Air Force initiated ICBM research in 1945 with the MX-774. However, its funding was cancelled and only three partially successful launches were conducted in 1947. In 1951, the Air Force began a new ICBM program called MX-1593, and by 1955 this program was receiving top-priority funding. The MX-1593 program evolved to become the Atlas-A, with its maiden launch occurring on 11 June 1957, becoming the first successful American ICBM. Its upgraded version, the Atlas-D rocket, would later serve as an operational nuclear ICBM and be used as the orbital launch vehicle for Project Mercury

With the Cold War as an engine for change in the ideological competition between the United States and the Soviet Union, a coherent space policy began to take shape in the United States during the late 1950s. Korolev would take much inspiration from the competition as well, achieving many firsts to counter the possibility that the United States might prevail.

Beginnings

In 1955, with both the United States and the Soviet Union building ballistic missiles that could be utilized to launch objects into space, the "starting line" was drawn for the Space Race. In separate announcements, just four days apart, both nations publicly announced that they would launch artificial Earth satellites by 1957 or 1958. On 29 July 1955, James C. Hagerty

 spoke to international reporters at the Soviet embassy, and announced his country's intention to launch a satellite as well, in the "near future". On 30 August 1955, Korolev managed to get the Soviet Academy of Sciences to create a commission whose purpose was to beat the Americans into Earth orbit: this was the defacto start date for the Space Race.

Initially, President Eisenhower was worried that a satellite passing above a nation at over 100 kilometres (62.1 mi), might be construed as violating that nation's sovereign airspace. He was concerned that the Soviet Union would accuse the Americans of an illegal overflight, thereby scoring a propaganda victory at his expense. Eisenhower and his advisors believed that a nation's airspace sovereignty did not extend into outer space, acknowledged as the Kármán line

, which was a research-only booster. This meant that von Braun's team was not allowed to put a satellite into orbit with their Jupiter-C rocket, because of its intended use as a future military vehicle. On 20 September 1956, von Braun and his team did launch a Jupiter-C that was capable of putting a satellite into orbit, however the launch was used only as a suborbital test of nose cone reentry technology. Had von Braun's team been allowed to orbit a satellite in 1956, the Space Race might have been over before it gained sufficient momentum to yield real benefits.

First artificial satellites


Korolev received word about von Braun's 1956 Jupiter-C test, but thinking it was a satellite mission that failed, he expedited plans to get his own satellite in orbit. Since his R-7 was substantially more powerful than any of the American boosters, he made sure to take full advantage of this capability by designing Object D

Sputnik 3 was a Soviet satellite launched on May 15, 1958 from Baikonur cosmodrome by a modified R-7/SS-6 ICBM. It was a research satellite to explore the upper atmosphere and the near space, and carried a large array of instruments for geophysical research....

 as his primary satellite. It was given the designation 'D', to distinguish it from other R-7 payload designations 'A', 'B', 'G', and 'V' which were nuclear weapon payloads. Object D would dwarf the proposed American satellites, by having a weight of 1400 kilograms (3,086.5 lb), of which 300 kilograms (661.4 lb) would be composed of scientific instruments that would photograph the Earth, take readings on radiation levels, and check on the planet's magnetic field. However, things were not going along well with the design and manufacturing of the satellite, so in February 1957, Korolev sought and received permission from the USSR Council of Ministers to create a prosteishy sputnik (PS-1), or simple satellite. The Council also decreed that Object D be postponed until April 1958. The new sputnik was a shiny spherical ball that would be a much lighter craft, weighing 83.8 kilograms (184.7 lb) and having a 58 centimetres (22.8 in) diameter.
The satellite would not contain the complex instrumentation that Object D had, but it did have two radio transmitters operating on different short wave radio frequencies, the ability to detect if a meteoroid were to penetrate its pressure hull, and the ability to detect the density of the Earth's thermosphere

Korolev's fear was that von Braun might launch a Jupiter-C with a satellite payload, on, or around, the fourth or fifth of October, in conjunction with the paper. The fear of being beaten made him hasten the launch, moving it to the fourth of October.

Although he had the ability to take over manual control of his spacecraft in an emergency, it was flown in an automatic mode as a precaution; medical science at that time did not know what would happen to a human in the weightlessness of space. Vostok 1 orbited the Earth for 108 minutes and made its reentry over the Soviet Union, with Gagarin ejecting from the spacecraft at 7000 metres (22,965.9 ft), and landing by parachute.

Kennedy launches the Moon race

On 20 April 1961, about one week after Gagarin's flight, American President John F. Kennedy sent a memo to Vice President Lyndon B. Johnson
Lyndon B. Johnson
Lyndon Baines Johnson , often referred to as LBJ, was the 36th President of the United States after his service as the 37th Vice President of the United States...

, asking him to look into the state of America's space program, and into programs that could offer NASA the opportunity to catch up. Johnson responded about one week later, concluding that the United States needed to do much more to reach a position of leadership. Johnson recommended that a piloted moon landing was far enough in the future that it was likely that the United States could achieve it first.

On 25 May, Kennedy announced his support for the Apollo program and redefined the ultimate goal of the Space Race in an address to a special joint session of Congress:"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth."
His justification for the Moon Race, was that it was both vital to national security and it would focus the nation's energies in other scientific and social fields. He expressed his reasoning in the famous "We choose the Moon speech," on 12 September 1962, before a large crowd at Rice University

Proposed Joint U.S.-U.S.S.R. Moon Program

On 20 September 1963, in a speech before the United Nations General Assembly, President Kennedy proposed that the United States and the Soviet Union join forces in their efforts to reach the moon. Soviet Premier Nikita Khrushchev
Nikita Khrushchev
Nikita Sergeyevich Khrushchev led the Soviet Union during part of the Cold War. He served as First Secretary of the Communist Party of the Soviet Union from 1953 to 1964, and as Chairman of the Council of Ministers, or Premier, from 1958 to 1964...

Vostoks and Voskhods

The Soviet Union achieved another first, with the first dual-piloted flights, Vostok 3

Vostok 3 was a spaceflight of the Soviet space program intended to determine the ability of the human body to function in conditions of weightlessness and test the endurance of the Vostok 3KA spacecraft over longer flights...

Vostok 4
Vostok 4 was a mission in the Soviet space program. It was launched a day after Vostok 3 with cosmonaut Pavel Popovich on board—the first time that more than one manned spacecraft were in orbit at the same time. The two Vostok capsules came within of one another and ship-to-ship radio contact was...

 on 11–15 August 1962. The two spacecraft came within approximately 6.5 kilometres (4 mi) of one another, close enough for radio communication. The launching of two spacecraft from the same pad during a very short period of time represented a significant technical accomplishment, however there was no capability for the spacecraft to maneuver closer to each other, and over the course of the mission they continued to drift as far as 2850 kilometres (1,770.9 mi) apart.

The Soviet Union achieved yet another first when it launched not only the first woman, but also the first civilian, in space-- Valentina Tereshkova

. Launching a woman was reportedly Korolev's idea, and it was accomplished purely for propaganda value. Tereshkova was one of a small corps of female cosmonauts who were amateur parachutists, but Tereshkova was the only one to fly. The USSR didn't again open its cosmonaut corps to women until 1980, two years after the United States opened its astronaut corps to women.

Korolev had planned further, long-term missions for the Vostok spacecraft, and had four Vostoks in various stages of fabrication in late 1963 at his OKB-1

 facilities. At that time, the Americans announced their ambitious plans for the Project Gemini flight schedule. These plans included major advancements in spacecraft capabilities, including a two-person spacecraft, the ability to change orbits, the capacity to perform an extravehicular activity (EVA), and the goal of docking with another spacecraft. These represented major advances over the previous Mercury or Vostok spaceships, and Korolev felt the need to try to beat the Americans to many of these innovations. Korolev already had begun designing the Vostok's replacement, the next-generation Soyuz spacecraft, a multi-cosmonaut spacecraft that had at least the same capabilities as the Gemini spacecraft. However, Soyuz would not be available for at least three years, and it could not be called upon to deal with this new American challenge in 1964 or 1965. Political pressure in early 1964–which some sources claim was from Khrushchev while other sources claim was from other Communist Party officials—pushed him to modify his four remaining Vostoks to beat the Americans to new space firsts in the size of flight crews, and the duration of missions.

On 12 October 1964, the Chief Designer delivered another Soviet space-first when Voskhod 1
Voskhod 1
Voskhod 1 was the seventh manned Soviet space flight. It achieved a number of "firsts" in the history of manned spaceflight, being the first space flight to carry more than one crewman into orbit, the first flight without the use of spacesuits, and the first to carry either an engineer or a...

 launched the first multi-person spacecraft, with three cosmonauts in a modified Vostok spacecraft. The USSR touted another technological achievement during this mission: it was the first space flight during which cosmonauts performed in a shirt-sleeve-environment. However, flying without spacesuits was not due to safety improvements in the Soviet spacecraft's environmental systems; rather this innovation was accomplished because the craft's limited cabin space did not allow for spacesuits. Flying without spacesuits exposed the cosmonauts to significant risk in the event of potentially fatal cabin depressurization. This feat would not be repeated until the US Apollo Command Module flew in 1968; this later mission was designed from the outset to safely transport three astronauts in a shirt-sleeve environment

 and a small cadre of high-ranking Communist Party officials, deposed Premier Khrushchev as Soviet government leader a day after Voskhod 1 landed, in what was called the "Wednesday conspiracy".
The new political leaders, along with Korolev, ended the technologically troublesome Voskhod program, cancelling Voskhod 3 and 4, which were in the planning stages, and started concentrating on the race to the moon. Voskhod 2 would end up being Korolev's final achievement before his death, as it would become the last of the many space firsts that demonstrated the USSR's domination in spacecraft technology during the early 1960s. According to historian Asif Siddiqi, Korolev's accomplishments marked "the absolute zenith of the Soviet space program, one never, ever attained since." There would be a two-year pause in Soviet piloted space flights while Voskhod's replacement, the Soyuz spacecraft, was designed and developed.
On 18 March 1965, about a week before the first American piloted Project Gemini space flight, the USSR accelerated the Space Race competition, by launching the two-cosmonaut Voskhod 2

 and Alexey Leonov. Voskhod 2's design modifications included the first airlock to allow for extravehicular activity (EVA), also known as a spacewalk. Leonov performed the first-ever EVA as part of the mission. A fatality was narrowly avoided when Leonov's spacesuit expanded in the vacuum of space, preventing him from re-entering the spacecraft. He had to improvise, and perform the potentially fatal partial depressurization of his spacesuit in order to re-enter the airlock. He succeeded in safely re-entering the ship, but he and Belyayev faced further challenges when the spacecraft's atmospheric controls flooded the cabin with 45% pure oxygen, which had to be lowered to acceptable levels before re-entry. The reentry involved two more challenges: an improperly timed retrorocket firing caused the Voskhod 2 to land 386 kilometres (239.8 mi) off its designated target area, the town of Perm

 and docking of two craft, flight durations of sufficient length to simulate going to the Moon and back, Extra-vehicular Activity for extended periods, and accomplishing useful work rather than just "walking in space." Although Gemini took a year longer than planned to accomplish its first flight, Gemini took advantage of the USSR's two-year hiatus after Voskhod, which enabled the US to catch up and surpass the previous Soviet lead in piloted spaceflight. Gemini achieved several significant firsts during the course of ten piloted missions:

Soviet Moon program

The Soviet Union had planned to divide their lunar program into two separate manned programs: circumlunar flights in 1967 and lunar landings from 1968.

The circumlunar missions were to be launched by a UR-500 rocket, later known as the Proton. The cosmonauts would be flown to the Moon in the Soyuz 7K-L1
Soyuz 7K-L1
The Soyuz 7K-L1 spacecraft was designed to launch men from the Earth to circle the Moon without going into lunar orbit in the context of the Soviet manned moon-flyby program in Moon race. It was based on the Soyuz 7K-OK with several components stripped out to reduce the vehicle weight...

The Soviet lunar landing missions would use spacecraft derived from the Soyuz 7K-L1. The orbital module (Soyuz 7K-L3), the "Lunniy Orbitalny Korabl" (LOK), had a crew of two. The LOK and a separate lunar lander, the "Lunniy Korabl

In 1967, both nations faced serious challenges that brought their programs to a halt. Both nations had been rushing at full-speed on the Apollo and Soyuz programs, without paying due diligence to growing design and manufacturing problems. The results proved fatal to both pioneering crews.

The fire was probably caused by an electrical spark, and it grew out-of-control, fed by the spacecraft's pure oxygen atmosphere maintained at greater-than-normal atmospheric pressure. An investigative board detailed design and construction flaws in the spacecraft, and procedural failings including failure to appreciate the hazard of the pure-oxygen atmosphere as well as inadequate safety procedures. All these flaws had to be corrected over the next twenty-two months until the first piloted flight could be made.

, but his mission was plagued with problems. Early on his craft lacked sufficient electrical power because only one of two solar panels had deployed. Then the automatic attitude control system began malfunctioning and eventually failed completely, resulting in the craft spinning wildly. Komarov was able to stop the spin with the manual system, which was only partially effective. The flight controllers aborted his mission after only one day, and he made an emergency re-entry.
During re-entry a fault in the landing parachute system caused the primary chutes to fail, and the reserve chutes tangled together; Komarov was killed on impact.

Fixing these, and other, spacecraft faults caused an eighteen-month delay before piloted Soyuz flights could resume, similar to the US experience with Apollo. This, combined with Korolev's death, led to the quick unraveling of the Soviet Moon-landing program.

A few hours later, the crew performed the first-ever Trans-Earth injection (TEI) burn, to blast the Apollo 8 spacecraft out of lunar orbit and on to a trajectory back to the Earth. Just over two days later, on 27 December, Apollo 8 safely splashed down in the Pacific, completing another first: NASA's first dawn splashdown and recovery.

It turned out there was no chance of a piloted Soviet circumlunar flight during 1968, due to the unreliability of the Zonds. After the successive launch failures of the N1 rocket in 1969, Soviet plans for a piloted landing suffered first delay and ultimately cancellation. The launch pad explosion of the N-1 on 3 July 1969 was a significant setback. The rocket hit the pad after an engine shutdown, destroying itself and the launch facility.

Apollo 11

1969 saw the final leg of the Moon Race, with the United States leading it after the flight of Apollo 8. Unbeknownst to the Americans, the Soviet moon program was in deep trouble. Without the N-1 rocket, the Soviets had no way to land on the Moon. The next two Apollo missions proved that the Lunar Module worked well, both in low-Earth orbit and in lunar orbit. It was time to proceed to an actual landing mission. Under this backdrop, Apollo 11 was being prepared for a July encounter with the Moon.

, with Apollo 11 on board.

The lunar trip took just over three days. After achieving orbit, Armstrong and Aldrin transferred into the Lunar Module, named Eagle, and began their descent. After overcoming several computer malfunctions, Armstrong took over manual-flight-control at about 180 metres (590.6 ft), and guided the Lunar Module to a landing on the Moon's Sea of Tranquility at 4:17 p.m. EDT, 20 July 1969. The first humans on the Moon would wait another six hours before they ventured out of their craft. At 10:56:15 p.m. EDT, Armstrong became the first human to set foot on the Moon.
The first step was witnessed by at least 500 million TV viewers back on Earth. His first words when he stepped off the LM's landing pad were, "That's one small step for [a] man, one giant leap for mankind." Aldrin joined him on the surface almost 20 minutes later. Altogether, they spent just under two and one-quarter hours outside their craft. The next day, they performed the first launch from another celestial body, and rendezvoused with the Columbia Command Module.

Apollo 11 safely blasted out of Moon orbit on its way back to a splashdown in the Pacific Ocean on 24 July 1969. When the spacecraft splashed down, 2,982 days had passed since Kennedy committed the United States to landing a man on the moon and bringing him back safely to the Earth before the end of the decade; the mission was completed with just 161 days to spare. With the safe completion of the Apollo 11 mission, the Americans won the race to the Moon.

The 1970s

The early 1970s were rounded out by several more manned Moon landings, which featured expanded tasks including more sample returns, experiments, and extended EVA's with a lunar rover. The USSR continued for time with their N1 rocket, as well as more Soyuz flights to their Salyut stations. Unmanned spacecraft were in the limelight as well, with the USSR launching unmanned lunar sample return missions and probes to Mars and Venus. The US launched probes to Mars, Venus, Mercury, Jupiter

They were asphyxiated when their spacecraft's cabin lost all pressure, shortly after undocking. The disaster was blamed on a faulty cabin pressure valve, that allowed all the air to vent into space. The crew were not wearing pressure suits and had no chance of survival once the leak occurred.

Salyut 1's orbit was increased to prevent premature reentry, but further piloted flights were delayed while the Soyuz was redesigned to fix the new safety problem. The station re-entered the Earth's atmosphere on 11 October, after 175 days in orbit. The USSR attempted to launch a second Salyut-class station designated Durable Orbital Station-2 (DOS-2) on 29 July 1972, but a rocket failure caused it to fail to achieve orbit. After the DOS-2 failure, the USSR attempted to launch four more Salyut-class stations through 1975, with another failure due to an explosion of the final rocket stage, which punctured the station with shrapnel so that it wouldn't hold pressure.

Retrospectives

The meaning and nature of the space race is the subject to periodic retrospectives in American and other cultures. One such occurrence was in 2003 when Columbia was lost with crew during re-entry. Some more retrospectives took place with retirement of the U.S. Space Shuttle program in 2011 and the cancellation of Project Constellation

 fields—advanced greatly during this period. However, the effects of the Space Race went far beyond rocketry, physics, and astronomy. "Space age technology" extended to fields as diverse as home economics and forest defoliation studies, and the push to win the race changed the very nature of science education.

American concerns that they had fallen behind the Soviet Union in the race to space led quickly to a push by legislators and educators for greater emphasis on mathematics and the physical sciences in American schools. The United States' National Defense Education Act
National Defense Education Act
The National Defense Education Act , signed into law on September 2, 1958, provided funding to United States education institutions at all levels. The act authorized funding for four years, increasing funding per year: for example, funding increased on eight program titles from 183 million dollars...

 installations, a situation unparalleled in any other country and a direct consequence of the Space Race.

The scientists educated through these efforts helped develop technologies that have been adapted for use in the kitchen, in transportation systems, in athletics, and in many other areas of modern life. Dried fruits and ready-to-eat foods (in particular food sterilization and package sealing techniques), stay-dry clothing, and even no-fog ski goggles have their roots in space science.
Today over a thousand artificial satellites orbit earth, relaying communications data around the planet and facilitating remote sensing

Remote sensing is the acquisition of information about an object or phenomenon, without making physical contact with the object. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth by means of propagated signals Remote sensing...
