Korolev was keenly aware of the orbital possibilities of the rockets being designed as ICBMs, ideas that were shared by
Tikhonravov then working at
NII-4. On 30 August, Korolev met with members of the Soviet defense and scientific communities. As a result, he was allowed to use the R-7 rocket to launch satellites, and his project also gained support from the
Soviet Academy of Sciences. On 30 January 1956, the
USSR Council of Ministers officially approved the satellite project in its decree number 149-88ss. Despite earlier work done by Tikhonravov, much of its design, such as pressurized equipment, long-range communications systems, automated switches, and a metal construct to work in space, had little precedent. By mid-1956, Korolev had finalized the modifications to the R-7 ICBM for a satellite launch, but the project as a whole was falling behind schedule. He feared that the United States would launch a satellite before he could. This was heightened by reports of the American
Project Vanguard and a secret 1956 missile launch from
Patrick Air Force Base, Florida. Meanwhile, testing of the R-7 rocket engine showed that its
specific impulse would be lower than projected and thus insufficient for Object D's specifications. Korolev sent a revised plan calling for a simpler payload of approximately 100 kilograms. It was approved on 25 January 1957 as '
Object PS'. The instrument-laden
Sputnik 3 spacecraft was launched initially on 27 April 1958, but the satellite had a failure with the engine which caused the satellite to fall back down to Earth in separate pieces. On 15 May 1958, Sputnik 3 was successfully launched into orbit. The tape recorder that was to store the data failed after launch. As a result, the discovery and mapping of the
Van Allen radiation belts was 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 Even before the
Sputnik 1 launch, Korolev was interested in getting to the Moon. He came up with the notion to modify the R-7 missile in order to carry a package to the Moon. However, it was not until 1958 that this idea was approved, after Korolev wrote a letter explaining that his current technology would make it possible to get to 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.
Mechta is the Russian word meaning "dream", and this is the name Korolev called his moon ships. Officially, the Soviet Union called them
Lunas. 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!?" The
Luna 1 mission on 2 January 1959 was intended to impact the surface, but missed by about . Nevertheless, this probe became the first to reach escape velocity and the first to go near the Moon, as well as becoming the first man-made object to orbit the Sun. 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 of the Moon, which was something the people of Earth had never seen beforehand. The Luna missions were intended to make a successful soft landing on the Moon, but Korolev was unable to see a success.
Luna 4 and
Luna 6 both missed,
Luna 5,
Luna 7, and
Luna 8 all crashed on the Moon. It was not until after Korolev's death that the Soviet Union successfully achieved a soft landing on the Moon with
Luna 9. Towards the latter part of Korolev's life, he had been working on projects for reaching the planets
Mars and
Venus, and even had spacecraft ready to reach both. The United States was also working towards reaching these planets, so it was a race to see who would be successful. Korolev's two initial Mars probes suffered from engine failures, and the five probes the Soviet Union launched in hopes of reaching Venus all failed between 1961 and 1962, Korolev himself supervised the launches of all probes. On 1 November 1962, the Soviet Union successfully launched
Mars 1 and although communications failed, was the first to complete a
flyby of Mars. Later, the Soviet Union launched
Venera 3, which was the first impact of Venus. It was not until after Korolev's death that the Soviet Union impacted Mars. 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
Yevpatoria 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 and
Marshal Kirill Moskalenko, before Gagarin's launch in
Vostok 1 (1961) Although he had conceived of the idea as early as 1948, 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 space suit, unlike the United States' pure
oxygen system, was 80 percent
nitrogen and only 20 percent oxygen. The capsule had an escape mechanism for problems prior to launch, and a soft-landing and ejection system during the recovery. The spacecraft was spherical, just like the Sputnik design, and Korolev explained his reasoning for this by saying "the spherical shape would be more stable dynamically". Beginning with work on the Vostok,
Konstantin Feoktistov was recruited directly by Korolev to be the principal designer for
crewed spaceflight vehicles. On 15 May 1960 an uncrewed prototype performed 64 orbits of Earth, but the reentry maneuver failed. On 28 July 1960, two dogs by the names of Chaika and Lishichka were launched into space, but the mission was unsuccessful when an explosion killed the dogs. However, on 19 August, the Soviet Union became the first to successfully recover living creatures back to Earth. The dogs,
Belka and
Strelka were successfully launched into space on a Vostok spacecraft and they completed eighteen orbits. Following this, the Soviet Union sent a total of six dogs into space, two in pairs, and two paired with a dummy. Unfortunately, not all the missions were successful. After gaining approval from the government, a modified version of Korolev's R-7 was used to launch
Yuri Alexeevich Gagarin into orbit on 12 April 1961, which was before the United States was able to put
Alan Shepard into space. Korolev served as capsule coordinator, and was able to speak to Gagarin who was inside the capsule. 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 planned to move forward with
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-crewed 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 Chelomey. But Russian Space Web describes this demand by Khrushchev as a legend and Challenge to Apollo says that the evidence that Khrushchev would have ordered these missions does not survive scrutiny. Cosmonaut
Alexei Leonov described the authority Korolev commanded at this time. On August 11, 1962, Korolyov launched the first group flight with
Vostok 3 and 4 (with
Andriyan Nikolayev and
Pavel Popovich). The two spacecraft approached each other to 6.5 km. This was based on precise calculations already at launch and not on steering (maneuvering) of the spacecraft. During the flight, at Korolev's request, Popovich sang the Ukrainian song "
Watching the sky and thinking a thought ..." (Ukrainian Дивлюсь я на небо, та й думку гадаю ..., poem by
Mykhailo Petrenko) the first song from outer space. The
Voskhod was designed as an incremental improvement on the Vostok to meet Khruschev's goal. As a single capsule would be ineffective for proper travel to the Moon, the vehicle needed to be able to hold more people. Khrushchev ordered Korolev to launch three people on the Voskhod capsule quickly, as the United States was already doing unmanned tests of the 2 person
Gemini. Korolev accepted, on the condition that more backing would be given to his
N-1 rocket program. 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. So the craft would need much larger parachutes in order to land safely. Early tests with the craft resulted in some failures 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 uncrewed 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 spacewalk with their
Gemini program, the Soviets decided to trump them again by performing a spacewalk 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 spacewalk. The flight very nearly ended in disaster, as Leonov was just barely able to re-enter through the airlock, 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
Moon race, Korolev's staff started to design the immense
N1 rocket in 1961, using the
NK-15 liquid fuel rocket engine. He also was working on the design for the
Soyuz spacecraft that was intended to carry crews to LEO and to the Moon. 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 of the shortcomings he discerned in Korolev's approach, which in his opinion was why the Soviets didn't land on the Moon: Another reason the Soviet crewed lunar program didn't succeed was the rivalry between Korolev and
Vladimir Chelomey. Their animosity was due to the intolerable persona of both men, and their desire for leadership at any cost. The two never said a harsh word about each other either in public or in private, but toppled each other's projects in any way possible. Instead of dividing competencies and responsibilities and cooperating in order to pursue the same goal, the two struggled for leadership in the space program. According to Khrushchev, who worked for Chelomey and knew both men well, they both would have preferred the Americans to land on the Moon first rather than their rival. ==Death==
