  Lunar probe; passed within 5,995 km of moon but did not hit it as planned due to a failure of the launch vehicle control system. Went into solar orbit. First manmade object to attain of escape velocity. Also known as Mechta ("Dream"), popularly called Lunik I. Because of its high velocity and its announced package of various metallic emblems with the Soviet coat of arms, it was concluded that Luna 1 was intended to impact the Moon. After reaching escape velocity, Luna 1 separated from its 1472 kg third stage. The third stage, 5.2 m long and 2.4 m in diameter, travelled along with Luna 1. On 3 January, at a distance of 113,000 km from Earth, a large (1 kg) cloud of sodium gas was released by the spacecraft. This glowing orange trail of gas, visible over the Indian Ocean with the brightness of a sixth-magnitude star, allowed astronomers to track the spacecraft. It also served as an experiment on the behavior of gas in outer space. Luna 1 passed within 5,995 km of the Moon's surface on 4 January after 34 hours of flight. It went into orbit around the Sun, between the orbits of Earth and Mars. The measurements obtained during this mission provided new data on the Earth's radiation belt and outer space, including the discovery that the Moon had no magnetic field and that a solar wind, a strong flow of ionized plasma emmanating from the Sun, streamed through interplanetary space.

  First probe to impact lunar surface. Delivered a pennant to the surface of the Moon and conducted research during flight to the Moon. Impacted Moon 13 Sep 1959 at 22:02:04 UT, Latitude 29.10 N, Longitude 0.00 - Palus Putredinis, east of Mare Serenitatis near the Aristides, Archimedes, and Autolycus craters. After launch and attainment of escape velocity, Luna 2 separated from its third stage, which travelled along with it towards the Moon. On 13 September the spacecraft released a bright orange cloud of sodium gas which aided in spacecraft tracking and acted as an experiment on the behavior of gas in space. On 14 September, after 33.5 hours of flight, radio signals from Luna 2 abruptly ceased, indicating it had impacted on the Moon. Some 30 minutes after Luna 2, the third stage of its rocket also impacted the Moon. The mission confirmed that the Moon had no appreciable magnetic field, and found no evidence of radiation belts at the Moon.

COSPAR: 1959-Theta-1. Apogee: 499,998 km (310,683 mi). Perigee: 500 km (310 mi). Inclination: 55.00 deg. Period: 21,563.20 min.

  Luna 3 was the third spacecraft successfully launched to the Moon and the first to return images of the lunar far side. It was launched on a figure-eight trajectory which brought it over the Moon (closest approach to the Moon was 6200 km) and around the far side, which was sunlit at the time. It was stabilized while in optical view of the far side of the Moon. On October 7, 1959, the television system obtained a series of 29 photographs over 40 minutes, covering 70% of the surface, that were developed on-board the spacecraft. The photographs were scanned and 17 were radio transmitted to ground stations in facsimile form on October 18, 1959, as the spacecraft, in a barycentric orbit, returned near the Earth. The photographs were to be retransmitted at another point close to Earth but were not received. The spacecraft returned very indistinct pictures, but, through computer enhancement, a tentative atlas of the lunar farside was produced. These first views of the lunar far side showed mountainous terrain, very different from the near side, and two dark regions which were named Mare Moscovrae (Sea of Moscow) and Mare Desiderii (Sea of Dreams).

  The Soviet Union launched a Vostok 1KP prototype manned spacecraft (without heat shield; not recoverable) into near-earth orbit. Called Sputnik IV by the Western press. On May 19, at 15:52 Moscow time, the spacecraft was commanded to retrofire. However the guidance system had oriented the spacecraft incorrectly and the TDU engine instead put the spacecraft into a higher orbit. Soviet scientists said that conditions in the cabin, which had separated from the remainder of the spacecraft, were normal.

  The Soviet Union launched its second unmanned test of the Vostok spacecraft, the Korabl Sputnik II, or Sputnik V. The spacecraft carried two dogs, Strelka and Belka, in addition to a gray rabbit, rats, mice, flies, plants, fungi, microscopic water plants, and seeds. Electrodes attached to the dogs and linked with the spacecraft communications system, which included a television camera, enabled Soviet scientists to check the animals' hearts, blood pressure, breathing, and actions during the trip. After the spacecraft reentered and landed safely the next day, the animals and biological specimens were reported to be in good condition.

• Mars probe 1M s/n 1 failure. - . Payload: 1M s/n 1. Mass: 640 kg (1,410 lb). Nation: Russia. Agency: RVSN. Program: Mars. Class: Mars. Type: Mars probe. Spacecraft Bus: 1MV. Spacecraft: Mars 1M. Decay Date: 1960-10-10 .

  This was the Soviet Union's first attempt at a planetary probe. Mars probe intended to photograph Mars on a flyby trajectory. The possible cause lay in resonance vibrations of upper stages during Stage 2 burning, which led to break of contact in the command potentiometer of the gyrohorizon. As a result a pitch control malfunctioned and the launcher began to veer off the desired ascent profile. On exceeding 7 degrees of veering in pitch, the control system failed. The upper stage with the payload reached an altitude of 120 km before burning up on re-entry into the atmosphere above East Siberia.

  The Soviet Union launched its third spaceship satellite, Korabl Sputnik III, or Sputnik VI. The spacecraft, similar to those launched on May 15 and August 19, carried the dogs Pcheka and Mushka in addition to other animals, insects, and plants. Deorbited December 2, 1960 7:15 GMT. Burned up on reentry due to steep entry angle (retrofire engine did not shut off on schedule and burned to fuel depletion).

• Korabl-Sputnik - . Payload: Vostok 1K s/n 4. Mass: 4,730 kg (10,420 lb). Nation: Russia. Agency: RVSN. Program: Vostok. Class: Manned. Type: Manned spacecraft. Spacecraft: Vostok. Decay Date: 1960-12-20 .

  Unable to reach orbital velocity, the Vostok prototype separated while the third stage was still firing. While the ejection seat failed to operate, the capsule did make a hard landing in severe winter conditons in Siberia. It was recovered after some time, and the dogs Kometa and Shutka were alive. As a result of this flight the ejection seat was developed with a heat shield designed to protect the pilot in the event of a launch vehicle failure up to shut down of the first stage.

• Sputnik 7 - . Payload: 2MV-2 s/n 1. Mass: 6,483 kg (14,292 lb). Nation: Russia. Related Persons: Glushko, Korolev. Agency: RVSN. Program: Venera. Class: Venus. Type: Venus probe. Spacecraft Bus: 1MV. Spacecraft: Venera 1VA. Decay Date: 1961-02-26 . USAF Sat Cat: 71 . COSPAR: 1961-Beta-1. Apogee: 318 km (197 mi). Perigee: 212 km (131 mi). Inclination: 64.90 deg. Period: 89.80 min.

  The escape stage entered parking orbit but the main engine cut off just 0.8 s after ignition due to cavitation in the oxidiser pump and pump failure.. The payload attached together with escape stage remained in Earth orbit.

  The booster launched into a beautiful clear sky, and it could be followed by the naked eye for four minutes after launch. The third stage reached earth parking orbit, but the fourth stage didn't ignite. It was at first believed a radio antenna did not deploy from the interior of the stage, and it did not receive the ignition commands. Therefore the Soviet Union has successfully orbited a record eight-tonne 'Big Zero' into orbit. The State Commission meets two hours after the launch, and argues whether to make the launch public or not, and how to announce it. Glushko proposes the following language for a public announcement: 'with the objective of developing larger spacecraft, a payload was successfully orbited which provided on the first revolution the necessary telemetry'. Korolev and the others want to minimize any statement, to prevent speculation that it was a reconnaissance satellite or a failed manned launch. Kamanin's conclusion - the rocket didn't reach Venus, but it did demonstrated a new rocket that could deliver an 8 tonne thermonuclear warhead anywhere on the planet. The commission heads back to Moscow.

• Venera 1 - . Payload: 1VA s/n 2, Venera 1 (Sputnik 8, AMS). Mass: 644 kg (1,419 lb). Nation: Russia. Related Persons: Korolev. Agency: RVSN. Program: Venera. Class: Venus. Type: Venus probe. Spacecraft Bus: 1MV. Spacecraft: Venera 1VA. USAF Sat Cat: 80 . COSPAR: 1961-Gamma-1.

  Venera 1 was the first spacecraft to fly by Venus. The 6424 kg assembly was launched first into a 229 x 282 km parking orbit, then boosted toward Venus by the restartable Molniya upper stage. On 19 February, 7 days after launch, at a distance of about two million km from Earth, contact with the spacecraft was lost. On May 19 and 20, 1961, Venera 1 passed within 100,000 km of Venus and entered a heliocentric orbit. This failure resulted in only the following objectives being met: checking of methods of setting space objects on an interplanetary course; checking of extra-long-range communications with and control of the space station; more accurate calculation of the dimension of the solar system; a number of physical investigations in space.

  First manned spaceflight, one orbit of the earth. Three press releases were prepared, one for success, two for failures. It was only known ten minutes after burnout, 25 minutes after launch, if a stable orbit had been achieved.

  The payload included life-support equipment and radio and television to relay information on the condition of the pilot. The flight was automated; Gagarin's controls were locked to prevent him from taking control of the ship. The combination to unlock the controls was available in a sealed envelope in case it became necessary to take control in an emergency. After retrofire, the service module remained attached to the Sharik reentry sphere by a wire bundle. The joined craft went through wild gyrations at the beginning of re-entry, before the wires burned through. The Sharik, as it was designed to do, then naturally reached aerodynamic equilibrium with the heat shield positioned correctly.

  Gagarin ejected after re-entry and descended under his own parachute, as was planned. However for many years the Soviet Union denied this, because the flight would not have been recognized for various FAI world records unless the pilot had accompanied his craft to a landing.

Class: Manned. Type: Manned spacecraft. Flight: Vostok 2. Spacecraft: Vostok. Duration: 1.00 days. Decay Date: 1961-08-07 . USAF Sat Cat: 168 . COSPAR: 1961-Tau-1. Apogee: 221 km (137 mi). Perigee: 172 km (106 mi). Inclination: 64.80 deg. Period: 88.40 min.

  Second manned orbital flight. The Soviet Union successfully launched Vostok II into orbit with Gherman S. Titov as pilot. The spacecraft carried life-support equipment, radio and television for monitoring the condition of the cosmonaut, tape recorder, telemetry system, biological experiments, and automatic and manual control equipment. Flight objectives: Investigation of the effects on the human organism of a prolonged flight in orbit and subsequent return to the surface of the Earth; investigation of man's ability to work during a prolonged period of weightlessness. Titov took manual control of spacecraft but suffered from space sickness. He was equipped with a professional quality Konvas movie camera, with which ten minutes of film of the earth were taken through the porthole. Both television and film images were taken of the interior of the spacecraft. Like Gagarin, Titov experienced problems with separation of the service module after retrofire. Titov was never to fly again, after being assigned to the Spiral spaceplane, which turned out to be a dead-end project. A biography of him by Martin Caidin ('I Am Eagle') made him somewhat more accessible than Gagarin to the West.

• Zenit-2 11F61 s/n 1 - . Payload: Zenit-2 11F61 s/n 1. Mass: 4,610 kg (10,160 lb). Nation: Russia. Agency: RVSN. Class: Surveillance. Type: Military surveillance satellite. Spacecraft Bus: Vostok. Spacecraft: Zenit-2 satellite. Decay Date: 1961-12-11 .

  First attempted launch of Zenit photo-reconnaisance satellite. According to Kamanin, there was a problem with the third stage, and the capsule landed between Novosibirsk and Yakutsk, but could not be located. There was no information on the nature of the problem. Korolev stayed at Tyuratam, preparing for the next launch attempt.

• Cosmos 4 - . Payload: Zenit-2 11F61 s/n 2. Mass: 4,610 kg (10,160 lb). Nation: Russia. Related Persons: Nikolayev, Popovich. Agency: RVSN. Class: Surveillance.

  Area survey photo reconnaissance satellite. Program partially completed. Failure of primary spacecraft orientation system. It was to spend four days in space, to be followed by another mission during 5-10 May. This meant that Vostok 3/4 could not be launched before 20-30 May. The cosmonaut prime crew returned from their in-suit parachute training at Fedosiya.

  Area survey photo reconnaissance satellite. Third attempted launch of Zenit photo-reconnaissance satellite. It blew up 300 m from the pad, and did enough damage to put the launch complex out of operation for a month. Therefore the Vostok 3/4 launches could not take place until the end of July at the earliest.

  Joint flight with Vostok 4. The first such flight, where Vostok capsules were launched one day apart, coming within a few kilometers of each other at the orbital insertion of the second spacecraft. The flight was supposed to occur in March, but following various delays, one of the two Vostok pads was damaged in the explosion of the booster of the third Zenit-2 reconnsat in May. Repairs were not completed until August. Vostok 3 studied man's ability to function under conditions of weightlessness; conducted scientific observations; furthered improvement of space ship systems, communications, guidance and landing. Immediately at orbital insertion of Vostok 4, the spacecraft were less than 5 km apart. Popovich made radio contact with Cosmonaut Nikolayev. Nikolayev reported shortly thereafter that he had sighted Vostok 4. Since the Vostok had no maneuvering capability, they could not rendezvous or dock, and quickly drifted apart. The launches did allow Korolev to offer something new and different, and gave the launch and ground control crews practice in launching and handling more than one manned spacecraft at a time. The cosmonaut took colour motion pictures of the earth and the cabin interior. Additional Details: here....

• Vostok 4 - . Call Sign: Berkut (Golden Eagle ). Crew: Popovich. Backup Crew: Komarov, Volynov. Payload: Vostok 3KA s/n 6. Mass: 4,728 kg (10,423 lb). Nation: Russia. Related Persons: Nikolayev. Agency: RVSN. Program: Vostok. Class: Manned. Type: Manned spacecraft. Flight: Vostok 4. Spacecraft: Vostok. Duration: 2.96 days. Decay Date: 1962-08-15 . USAF Sat Cat: 365 . COSPAR: 1962-A-Nu-1. Apogee: 211 km (131 mi). Perigee: 159 km (98 mi). Inclination: 65.00 deg. Period: 88.20 min.

  Joint flight with Vostok 3. Acquisition of experimental data on the possibility of establishing a direct link between two space ships; coordination of astronauts' operations; study of the effects of identical spaceflight conditions on the human organism. The launch of Popovich proceeds exactly on schedule, the spacecraft launching with 0.5 seconds of the planned time, entering orbit just a few kilometers away from Nikolayev in Vostok 3. Popovich had problems with his life support system, resulting in the cabin temperature dropping to 10 degrees Centigrade and the humidity to 35%. The cosmonaut still managed to conduct experiments, including taking colour motion pictures of the terminator between night and day and the cabin interior.

  Despite the conditions, Popovich felt able to go for the full four days scheduled. But before the mission, Popovich had been briefed to tell ground control that he was 'observing thunderstorms' if he felt the motion sickness that had plagued Titov and needed to return on the next opportunity. Unfortunately he actually did report seeing thunderstorms over the Gulf of Mexico, and ground control took this as a request for an early return. He was ordered down a day early, landing within a few mintutes of Nikolayev. Only on the ground was it discovered that he was willing to go the full duration, and that ground control had thought he had given the code.

  Attempt to launch a probe towards Mars. The launch went well, but the fourth stage motor burnt for only 45s of the planned 240s. The stage remained in Earth orbit. However Kamanin notes that it was good that the launch of the basic vehicle was a success - it gave the visiting female cosmonauts confidence in the rocket they will have to ride.

  Mars probe intended to photograph Mars on a flyby trajectory. Launched from Sputnik 23 in a 157 x 238 km, 65 degree parking orbit. Sixty-one radio transmissions were held in which a large amount of data was collected. On March 21, 1963, when the spacecraft was at a distance of 106 million km communications ceased, possibly due to a malfunction in the spacecraft orientation system. Mars 1 closest approach to Mars occurred on June 19, 1963 at a distance of approximately 193,000 km, after which the spacecraft entered a heliocentric orbit. Announced mission: Prolonged exploration of outer space during flight to the planet Mars; establishment of inter-planetary radio communications; photgraphing of the planet Mars and subsquent radio-transmission to Earth of the photographs of the surface of Mars thus obtained.

  Mars probe intended to make a soft landing on Mars. Although the escape stage and payload reached orbit, the strong third stage vibrations shook a fuse loose from its mount in the main nozzle of the escape stage Block L's engine. The engine could not be ignited and remained in Earth orbit. It decayed about two months after insertion.

  Luna 4 was the second attempted Soviet unmanned lunar soft lander probe. The spacecraft, rather than being sent on a straight trajectory toward the Moon, was placed first in an earth parking orbit. The rocket stage then reignited and put the spaccecraft on a translunar trajectory. Failure of Luna 4 to make a required midcourse correction resulted in it missing the Moon by 8336.2 km on April 6, at 4:26 a.m. Moscow time. It thereafter entered a barycentric Earth orbit. The Soviet news agency, Tass, reported that data had been received from the spacecraft throughout its flight and that radio communication would continue for a few more days.

  Joint flight with Vostok 6. The Soviet Union launched Vostok 5, piloted by Lt. Col. Valery F. Bykovsky. Two days later Lt. Valentina V. Tereshkova, the first spacewoman, followed in Vostok 6. On its first orbit, Vostok 6 came within about five km of Vostok 5, the closest distance achieved during the flight, and established radio contact. Both cosmonauts landed safely on June 19. The space spectacular featured television coverage of Bykovsky that was viewed in the West as well as in Russia. Unlike earlier missions, only a black and white film camera was carried. Photometric measurements of the earth's horizon were made.

  Mission objectives were officially: further study of the effect of various space-flight factors in the human organism; extensive medico-biological experiments under conditions of prolonged flight; further elaboration and improvement of spaceship systems.

  Vostok 5 was originally planned to go for a record eight days. The launch was delayed repeatedly due to high solar activity and technical problems. Finally the spacecraft ended up in a lower than planned orbit. Combined with increased atmospheric activity due to solar levels, Vostok 5 quickly decayed temperatures in the service module reached very high levels.

  Bykovsky also experienced an unspecified problem with his waste management system (a spill?) which made conditions in the cabin 'very uncomfortable'. He was finally ordered to return after only five days in space.

  To top it all off, once again the Vostok service module failed to separate cleanly from the reentry sphere. Wild gyrations ensued until the heat of reentry burned through the non-separating retraining strap.

  Joint flight with Vostok 5. First woman in space, and the only Russian woman to go into space until Svetlana Savitskaya 19 years later. On its first orbit, Vostok 6 came within about five km of Vostok 5, the closest distance achieved during the flight, and established radio contact. Flight objectives included: Comparative analysis of the effect of various space-flight factors on the male and female organisms; medico-biological research; further elaboration and improvement of spaceship systems under conditions of joint flight. It was Korolev's idea just after Gagarin's flight to put a woman into space as yet another novelty. Khrushchev made the final crew selection. Korolev was unhappy with Tereshkova's performance in orbit and she was not permitted to take manual control of the spacecraft as had been planned.

  Unmanned test of Voskhod spacecraft. At 07:00 the State Commission meets at Area 2. All Chief Designers, Commanders, and Section report that all is ready for flight. The commission gives the order to proceed with the launch. Weather at the pad is 7 balls, 8-10 m/s wind with gusts to 15 m/s, temperature 9 to 12 deg C. Weather in the recovery zones is reported as winds up to 15 m/s. Weather in the recovery zone is not clear, but that is not considered an impediment, and in fact Kamanin would like to see how the landing system functions in bad conditions. Kamanin visits the pad at T-30 seconds; at T-20 seconds, the veranda at IP-1 has over 50 viewers of the launch, including 15 cosmonaut candidates and the 7 Voskhod cosmonauts. Kamanin is relegated to the IP-1 veranda this time, with Rudenko, Kirillov, and Tyulin the bunker adjacent to the pad. Korolev stays with the booster until T-5 minutes, then enters the bunker. The booster ignites precisely at 10:00; the strap-ons burn out and are jettisoned at T+120 seconds; the core burns out and the final stage ignites at T+290 seconds; and at T+523 seconds spacecraft 3KV number 2 is placed in orbit as the final stage shuts down. The spacecraft separates and all systems look normal.

  The U.S.S.R. launched the world's first multi-manned spacecraft, Voskhod I, the first to carry a scientist and a physician into space. The crew were Col. Vladimir Komarov, pilot; Konstantin Feoktistov, scientist; and Boris Yegorov, physician. Potentially dangerous modification of Vostok to upstage American Gemini flights; no spacesuits, ejection seats, or escape tower. One concession was backup solid retrorocket package mounted on nose of spacecraft. Seats mounted perpendicular to Vostok ejection seat position, so crew had to crane their necks to read instruments, still mounted in their original orientation. Tested the new multi-seat space ship; investigated the in-flight work potential and co-operation of a group of cosmonauts consisting of specialists in different branches of science and technology; conducted scientific physico-technical and medico-biological research. The mission featured television pictures of the crew from space.

  Coming before the two-man Gemini flights, Voskhod 1 had a significant worldwide impact. In the United States, the "space race" was again running under the green flag. NASA Administrator James E. Webb, commenting on the spectacular, called it a "significant space accomplishment." It was, he said, "a clear indication that the Russians are continuing a large space program for the achievement of national power and prestige." Additional Details: here....

  Mars probe intended to photograph Mars on a flyby trajectory. Zond 2 was launched from an earth parking orbit towards Mars to test space-borne systems and to carry out scientific investigations. Zond 2 carried six electric rocket engines of plasma type that served as actuators of the attitude control system. The communications system failed during April 1965. The spacecraft flew by Mars on August 6, 1965, at a distance of 1500 km.

  First spacewalk, with a two man crew of Colonel Pavel Belyayev and Lt. Colonel Aleksey Leonov. During Voskhod 2's second orbit, Leonov stepped from the vehicle and performed mankind's first "walk in space." After 10 min of extravehicular activity, he returned safely to the spacecraft through an inflatable airlock.

  This mission was originally named 'Vykhod ('Exit/Advance'). It almost ended in disaster when Leonov was unable to reenter the airlock due to stiffness of the inflated spacesuit. He had to bleed air from the suit in order to get into the airlock. After Leonov finally managed to get back into the spacecraft cabin, the primary hatch would not seal completely. The environmental control system compensated by flooding the cabin with oxygen, creating a serious fire hazard in a craft only qualified for sea level nitrogen-oxygen gas mixes (Cosmonaut Bondarenko had burned to death in a ground accident in such circumstances, preceding the Apollo 204 disaster by many years).

  Soft lunar landing attempt. Western observers, among them England's Sir Bernard Lovell, correctly speculated that the craft's mission was a soft landing. After launch fom Baikonur and five successful communications sessions the spacecraft performed a midcourse correction maneuver on 10 May. Unfortunately a problem developed in a flotation gyroscope (it did not have enough time to warm up properly) in the I-100 guidance control unit and control was lost so the spacecraft began spinning around its main axis. It was brought back under control, but at the time of the next maneuver, the main retrorocket system failed due to a ground control error in calculating the setpoints, and the spacecraft, though still headed for the Moon, was far off its intended landing site. Problems again cropped up with the I-100 unit so a retrorocket burn could not take place and Luna 5 impacted the lunar surface some 700 km from the target point at about 19:10 UT on 12 May 1965, becoming the second Soviet probe to hit the Moon. A Soviet announcement gave the impact point as the Sea of Clouds at roughly 31 degrees S, 8 degrees W. (Although a later analysis gave a very different estimate of 8 degrees N, 23 degrees W.)

  Attempted unmanned lunar soft lander. Tass reported that all onboard equipment was functioning normally. During the mid-course correction on 9 June the main retro-rocket failed to cut off as scheduled and fired until all of its propellant was exhausted, due to an erroneous ground command sent to the timer. This put the spacecraft on a trajectory to miss the Moon. The spacecraft was put through all the motions of an actual landing, jettisoning the lander and deploying the airbags, as an apparently successful practice run for the ground crew despite the fact that it flew by the Moon at a distance of 161,000 km on 11 June. Contact was lost at a distance of 600,000 km from Earth, the spacecraft presumably entering a heliocentric orbit.

  Zond 3 was towards the moon and interplanetary space. The spacecraft was equipped with a TV system that provided automatic inflight film processing. On July 20, during lunar flyby, 25 pictures of very good quality were taken of the lunar farside from distances of 11,570 to 9960 km. The photos covered 19,000,000 km square of the lunar surface. Photo transmissions by facsimile were returned to earth from a distance of 2,200,000 km on July 29 and were retransmitted later from a distance of 31,500,000 km, thus proving the ability of the communications system. After the lunar flyby, Zond 3 continued space exploration in a heliocentric orbit. Those pictures showed clearly the heavily cratered nature of the surface. This mission dramatized the advances in space photography that the U.S.S.R. had made since its first far-side effort six years earlier.

  Lunar soft landing attempt. The Luna 7 spacecraft was intended to achieve a soft landing on the Moon. However, due to loss of attitude control during the final approach to the lunar surface, the retrorockets were prevented from firing to slow the spacecraft and it impacted the lunar surface at 9.8 N, 47.8 W in the Sea of Storms on 7 October 1965 at 22:08:24 UT.

  Soft landed on Moon 24 December 1966 at 18:01:00 GMT, Latitude 18.87 N, 297.95 E - Oceanus Procellarum. The petal encasement of the spacecraft was opened, antennas were erected, and radio transmissions to Earth began four minutes after the landing. On December 25 and 26, 1966, the spacecraft television system transmitted panoramas of the nearby lunar landscape at different sun angles. Each panorama required approximately 100 minutes to transmit. The spacecraft was equipped with a mechanical soil-measuring penetrometer, a dynamograph, and a radiation densitometer for obtaining data on the mechanical and physical properties and the cosmic-ray reflectivity of the lunar surface. It is believed that transmissions from the spacecraft ceased before the end of December 1966.

• Cosmos 140 - . Payload: Soyuz 7K-OK (P) s/n 3. Mass: 6,450 kg (14,210 lb). Nation: Russia. Agency: MOM. Program: Soyuz. Class: Manned. Type: Manned spacecraft. Spacecraft Bus: Soyuz.

Period: 88.30 min.

  After the self-destruction of the first Soyuz 7K-OK on re-entry, and the loss of the second one on the pad fire in December, the state commission ruled that the third 7K-OK model would be flown unpiloted on a solo mission. If this was successful then the fourth and fifth Soyuz would be flown on a manned docking mission. Once in orbit Cosmos 140 experienced attitude control problems due to a faulty star sensor resulting in excessive fuel consumption. The spacecraft couldn't keep the required orientation towards the sun to keep the solar panels illuminated, and the batteries discharged. Despite all of these problems the spacecraft remained controllable. An attempted manoeuvre on the 22nd revolution still showed problems with the control system. It malfunctioned yet again during retrofire, leading to a steeper than planned uncontrolled ballistic re-entry. The re-entry capsule itself had depressurised on separation from the service module due to a fault in the base of the capsule. A 300 mm hole burned through in the heat shield during re-entry. Although such events would have been lethal to any human occupants, the capsule's recovery systems operated and the capsule crashed through the ice of the frozen Aral Sea, 3 km from shore and 500 kilometres short of the intended landing zone. The spacecraft finally sank in 10 meters of water and had to be retrieved by divers. Still, the mission was deemed 'good enough' for the next mission to be a manned two-craft docking and crew transfer space spectacular. Mishin and Kamanin felt that a human crew could have sorted out the problems. They were also under intense pressure to achieve a manned circumlunar flight before the 50th Anniversary of the Soviet Revolution in October.

  Space disaster that put back Soviet lunar program 18 months. Soyuz 1 as active spacecraft was launched first. Soyuz 2, with a 3 man crew would launch the following day, with 2 cosmonauts spacewalking to Soyuz 1. However immediately after orbital insertion Komarov's problems started. One of the solar panels failed to deploy, staying wrapped around the service module. Although only receiving half of the planned solar power, an attempt was made to manoeuvre the spacecraft. This failed because of interference of the reaction control system exhaust with the ion flow sensors that were one of the Soyuz' main methods of orientation. Additional Details: here....

  Cosmos 213 was the target for Cosmos 212 in a successful test of Soyuz 7K-OK rendezvous and docking systems. The Cosmos 213 launch was the most accurate yet. The spacecraft was placed in orbit only 4 km from Cosmos 212, ready for a first-orbit docking. Both spacecraft were recovered, but Cosmos 213 was dragged by heavy wind across the steppes when the parachute lines didn't jettison at touchdown. This failure caused the upcoming Soyuz 2/3 manned docking mission to be scaled back.

  Venera 5 is launched at 9:26 Moscow time from LC-31 in -23 deg C temperatures. All proceeds according to plan. Afterwards Kamanin meets Babakin. Venera 6 is planned for launch in 10 January. He also plans two moon landings in 1969 and two in 1970 of soil sample return spacecraft. Kamanin does not believe America can achieve a manned moon landing in 1969, and therefore that Babakin has a very good chance of stealing their thunder.

  Meanwhile Venera 5 was launched from its parking orbit towards Venus to obtain atmospheric data. The spacecraft was very similar to Venera 4 although it was of a stronger design. When the atmosphere of Venus was approached, a capsule weighing 405 kg and containing scientific instruments was jettisoned from the main spacecraft. During satellite descent towards the surface of Venus, a parachute opened to slow the rate of descent. For 53 min on May 16, 1969, while the capsule was suspended from the parachute, data from the Venusian atmosphere were returned. The spacecraft also carried a medallion bearing the coat of arms of the U.S.S.R. and a bas-relief of V.I. Lenin to the night side of Venus.

  At 3 am an An-12 arrives from Moscow with ten newspapers, and letters for Shatalov, to be delivered by the Soyuz 5 crew to him as the first 'space mail'. At 05:15 the State Commission convened and approved launch at 10:04:30. The countdown proceeds normally; meanwhile communications sessions are held with Shatalov on Soyuz 4. The commission is taken by automobile convoy from Area 2, to Area 17, where the Soyuz 5 crew declares itself ready for flight. At T-25 minutes, with the crew already aboard the spacecraft, a piece of electrical equipment fails and needs to be replaced. Engineer-Captain Viktor Vasilyevich Alyeshin goes to the fuelled booster and replaces it. While doing this he notices that the access hatch has been secured with only three bolts, instead of the four required. Nevertheless the launch proceeds successfully. After Soyuz 5 is in orbit, it and Soyuz 4 begin their mutual series of manoeuvres for rendezvous and docking.

Period: 89.10 min.

  Intended first space station mission; soft docked with Salyut 1. Launch nearly scrubbed due to poor weather. Soyuz 10 approached to 180 m from Salyut 1 automatically. It was hand docked after faillure of the automatic system, but hard docking could not be achieved because of the angle of approach. Post-flight analysis indicated that the cosmonauts had no instrument to proivde the angle and range rate data necessary for a successful manual docking. Soyuz 10 was connected to the station for 5 hours and 30 minutes. Despite the lack of hard dock, it is said that the crew were unable to enter the station due to a faulty hatch on their own spacecraft. When Shatalov tried to undock from the Salyut, the jammed hatch impeded the docking mechanism, preventing undocking. After several attempts he was unable to undock and land.

  First space station flight, two years before the American Skylab. The Soyuz 11 launch proceeds without any difficulties. The first orbital correction in the set of rendezvous manoeuvres to head for Salyut 1 is made on the fourth revolution. At 15:00 Kamanin and other critical staff board a plane for the mission control centre at Yevpatoriya. The aircraft takes 4 hours 30 minutes to get there.

  Equipment aboard Salyut 1 included a telescope, spectrometer, electrophotometer, and television. The crew checked improved on-board spacecraft systems in different conditions of flight and conducted medico-biological research. The main instrument, a large solar telescope, was inoperative because its cover failed to jettison. A small fire and difficult working conditions will lead to a decision to return crew before planned full duration of 30 days.
