Kubasov Chronology

18 May 1964 - OKB-1 Voskhod candidates. Of 14 engineering cosmonaut candidates finally submitted by Korolev, only 6 survived preliminary screening and were sent for medical screening (Volkov, Grechko, Zaitsev, Kubasov, Makarov, Siborov, Feoktistov, and Yazdovskiy).


23 May 1966 - Energia Engineer Cosmonaut Training Group 1 selected..
6 July 1966 - State Commission on Manned Spaceflight. Tyulin heads a meeting that brings the Soyuz crewing dispute into the open. The opposing crews are represented as follows:

  • Soyuz s/n 3: VVS: commander: Komarov; backup Belyayev. MOM: commander: Dolgopolov; backup Grechko. Flight engineer: VVS: open; MOM: Makarov, Backup: Bugrov.
  • Soyuz s/n 4: VVS: commander: Bykovsky; backup Nikolayev. MOM: commander: Yeliseyev; backup Anokhin. Flight engineer: VVS: open; MOM: Kubasov, Backup: Volkov.

Kamanin is furious. Mishin and Tyulin think an engineer can be trained to be a spacecraft commander in three months, without passing a flight physical, without being a qualifed pilot, without screening and training on the centrifuge or zero-G aircraft, and without parachute training. They put no value in six years of VVS experience in cosmonaut training. They give no weight to the years of general training, spaceflight experience, and ten months of Soyuz-specific training his candidates have already had. He notes that the United States trains crews for a minimum of one to two years before a flight. Kamanin says this decision will not stand.


3 August 1966 - Sea tests of Soyuz. Mishin sends a letter to Kamanin, linking acceptance of his eight cosmonaut candidates from OKB-1 to continuation of sea recovery tests of the Soyuz capsule at Fedosiya. Kamanin's early hopes for Mishin have been dashed - not only is he no Korolev, but his erratic management style and constant attempts to work outside of accepted channels and methods, are ruining the space program. Later Gagarin briefs Kamanin on the impossibility of meeting Brezhnev, who has flown south for vacation without reacting to Gagarin's letter. Most likely, the letter will be referred to Ustinov, who will pass it to Smirnov, with instructions to suppress this "revolt of the military". Gagarin requests permission to resume flight and parachute training in preparation for a space mission assignment. Kamanin agrees to allow him to begin three months before the mission to space. This will be no earlier than 1967, as Gagarin will not be assigned to the first Soyuz flights.

Kamanin decides to smooth over matters with OKB-1. He calls Mishin, and then Tsybin, and agrees to begin processing of Anokhin, Yeliseyev, Volkov, and Kubasov as soon as he receives their personnel files and security clearances. Mishin promises to deliver the Soyuz mock-up of the Tu-104 zero-G aircraft soon - it slid from 20 July, then from 7 August.


23 August 1966 - Soyuz recovery training at sea. Nikolayev, Bykovsky, Komarov, Khrunov, Gorbatko, Kolodin, and Voronov complete two parachute jumps each, with landing at sea. Training in sea-recovery by helicopter, with the cosmonauts in spacesuits, will be completed over the next two days. Smirnov is ready to sign a letter from Afanasyev, Burnazyan and Keldysh creating a new civilian cosmonaut training centre under the Ministry of Medium Machine Building, separate from the VVS centre. The letter is not coordinated with the Defence Ministry, and contradicts the letter sent by the four marshals to the Central Committee. Kamanin prepares a vigorous refutation of the letter's position. The physicians' board on OKB-1 candidates has only cleared Yeliseyev for flight - they could not agree on Volkov, Kubasov, and Grechko. OKB-1 only submitted four candidates for review, not the eight promised.
2 September 1966 - Lunar flight cosmonauts assignments.. In the period 1966 to 1968 there were five simultaneous Soviet manned space projects (Soyuz 7K-OK orbital; Soyuz 7K-L1 circumlunar; Soyuz VI military; L3 manned lunar landing; Almaz space station). Cosmonaut assignments were in constant flux, resulting in many claims in later years that 'I was being trained for the first moon flight'.

Additional Details: Lunar flight cosmonauts assignments..


5 September 1966 - OKB-1 cosmonauts accepted for training.. Kubasov, Volkov, and Grechko have been accepted by the VVS for cosmonaut training, with some relaxation in health requirements. Yeliseyev, Dolgopolov and Makarov need more medical tests to be cleared.
7 September 1966 - Cosmonaut group leaders. Volkov, Grechko and Kubasov believe they can complete cosmonaut training in two months. Of course they know space technology, but Kamanin informs them that, with intensive training, they might be ready in one or two years. Popovich is assigned as leader of the Soyuz VI military spacecraft training group, and Belyayev as head of the Almaz military orbital station training group. Kaminin tells Severin to complete spaceuits for Khrunov and Gorbatko, but to ignore Mishin's orders to prepare suits for Anokhin and Yeliseyev. Anokhin has already been rejected due to his age and health, and Yeliseyev is still being tested. Kamanin reviews draft test programs for the UR-500K/L1 and N1-L3. He lines out statements inserted by Pravetskiy on joint training of cosmonauts by the MOM, Ministry of Public Health and VVS.
31 October 1966 - Soyuz crews have only 40 days for flight training.. First snow of the winter in Moscow. The training of Soyuz crews has to be completed within 40 days, but there is still no assurance the trainers will be ready by 15 November. Komarov will command the active spacecraft, and Bykovsky the passive. Gagarin and Nikolayev are their back-ups. The 20 December flight date can only be met if Khrunov and Gorbatko serve as flight engineers. Training of Kubasov, Volkov and Yeliseyev in 40 days is impossible. Yet there is still no agreement on the crew composition.
11 November 1966 - Soyuz crew dispute drags on. Kamanin visits OKB-1. Mishin certifies that unmanned Soyuz s/n 1 and 2 will fly by 26 November, and the manned spacecraft s/n 3 and 4 by the end of December. The departure of cosmonauts for the range must take place not later than 12-15 December. There remains only 30 days for training of the crews, the member of which have still have not been agreed. Mishin ignores common sense and still insists on the preparation of only his own engineers (Yeliseyev, Kubasov, Volkov, Makarov). The argument over the Soyuz crews continues without resolution up to the Central Committee level, then back down through the VPK and State Commission, over the next week.
18 November 1966 - N1 facilities tour. Rudenko and Kamanin meet with Mishin at Area 31 (18-20 kilometers east of Area 2). Launch preparations are reviewed, and Mishin satisfies them that the two Soyuz will be launched on 26-27 November. The State Commission will meet officially tomorrow at 16:00. For today, they tour the N1 horizontal assembly building at Area 13. Korolev planned the N1 as early as 1960-1961. It will have a takeoff mass of 2700-3000 tonnes and will be able to orbit 90-110 tonnes. The first stage of rocket has 30 engines, and the booster's overall height is114 m. The construction of the assembly plant, considered a branch of the Kuibyshev factory, began in 1963 but is still not finished. Two factory shops are in use, and the adjacent main assembly hall is truly impressive - more than 100 m in length, 60 m high, and 200 wide. Work on assembly of the ground test version of the rocket is underway. Assembly will be completed in 1967, and it will be used to test the systems for transport to the pad, erection of the booster, servicing, and launch preparations. The booster is to be ready for manned lunar launches in 1968. The construction site of the N1 launch pads occupies more than one square kilometre. Two pads are located 500 meter from each other. Between and around them is a mutli-storied underground city with hundreds of rooms and special equipment installations.

Only late in the night Rudenko and Mishin finally agree that the crews for the first manned Soyuz flights will be: Basic crews: Komarov, Bykovsky, Khrunov, Yeliseyev; Back-up crews: Gagarin, Nikolayev, Gorbatko, Kubasov. Meanwhile poor weather in Moscow is delaying zero-G training for the flight. In the last week only one weightless flight on the Tu-104 was possible - and a minimum of 24 flights need to be flown before the launch. It was therefore decided to ferry one Tu-104 to Tyuratam and train the cosmonauts here - it made its first flight today.


21 November 1966 - Soyuz crews agreed officially. The weather continues to deteriorate, and Kamanin considers moving the Tu-104 and cosmonauts to Krasnovodsk in order to get the 24 necessary zero-G flights before launch. At 11:00 the State Commission meets at Area 31. Present are Kerimov, Mishin, Rudenko, Kamanin, Komarov, Bykovsky, Khrunov, Yeliseyev, Anokhin and others. Mishin describes the status of preparations of Soyuz s/n 1, 2, 3, 4 for launch. He notes that the L1 and L3 lunar spacecraft are derived from the 7K-OK, and that these flights will prove the spacecraft technology as well as the rendezvous and docking techniques necessary for subsequent manned lunar missions. Feoktistov and the OKB-1 engineers say a launch cannot occur before 15 January, but Mishin insists on 25 December. That will leave only 20 days for cosmonaut training for the mission, including the spacewalk to 10 m away from the docked spacecraft. Faced with the necessity for the crews to train together as a team prior to flight, Mishin at long last officially agrees to the crew composition for the flights: Komarov, Bykovsky, Khrunov, and Yeliseyev as prime crews, with Gagarin, Nikolayev, Gorbatko, and Kubasov as back-ups. However a new obstacle appears. KGB Colonel Dushin reports that Yeliseyev goes by his mother's surname. His father, Stanislav Adamovich Kureytis , was a Lithuanian sentenced to five years in 1935 for anti-Soviet agitation. He currently works in Moscow as Chief of the laboratory of the Central Scientific Research Institute of the Shoe Industry. Furthermore Yeliseyev had a daughter in 1960, but subsequently annulled the marriage in 1966.

Later Feoktistov works with the crews on spacecraft s/n 1 to determine the feasibility of the 10-m EVA. The cosmonauts suggest a telescoping pole rather than a line be used to enable the cosmonaut to be in position to film the joined spacecraft. Bushuyev is tasked with developing the new hardware.


22 November 1966 - Crash efforts to make manned Soyuz flight by end of December. Faced with the possibility Yeliseyev will be bumped from the crew, Mishin requests accelerated training of Kubasov as a substitute. Kamanin asks the KGB for a definitive ruling on Yeliseyev's fitness. It will only be possible to meet a 25-29 December manned flight date by curtailing certain tests and supplementing the existing preparation and test staff with about 100 military staff from the Tyuratam range and 50 additional industrial technicians. Rudenko and Mishin have backed away from the agreement on the "final" crew compositions. Now they propose to assign as second cosmonauts the best two of Khrunov, Yeliseyev, and Kubasov. Kamanin adamantly opposes this latest deviation to plan.
7 December 1966 - Soyuz and L1 crew assignments. . Rudenko, Mishin, Kerimov and Kamanin agree on crews for upcoming flights. Komarov, Bykovsky, Khrunov, and Yeliseyev are assigned to Soyuz s/n 3 and 4; Gagarin, Nikolayev, Gorbatko, and Kubasov to Soyuz s/n 5 and 6, with Beregovoi, Shatalov, Volkov, and Makarov trained as back-ups. For Soyuz s/n 7, which will conduct space welding experiments with the Vulkan furnace, the commander will be either Komarov, Bykovsky, Gagarin, Nikolayev, Beregovoi, or Shatalov. The other two crewmembers will be either Lankin and Fartushniy from the Paton Institute, VVS cosmonaut Kolodin, or an engineer from OKB-1.

Crews for the L1 must be named in order to complete the five-month training program in time. Eight L1's are being completed to the manned configuration, but Mishin believes it is necessary to plan for only six manned missions. It is decided to train nine crews. Spacecraft commanders will be Komarov, Bykovsky, Nikolayev, Gagarin, Leonov, Khrunov, Volynov, Beregovoi, and Shatalov. Flight engineers will be Yeliseyev, Kubasov, Makarov, Volkov, and Grechko. Komarov, Bykovsky or Nikolayev will command the first circumlunar flight. Mishin promises to name the OKB-1 candidates for that flight by 8 December. Mishin and Kerimov agree that training of cosmonaut- researchers from the Academy of Sciences may begin, although both Mishin and Rudenko expressed doubts about cosmonaut candidate Yershov.

The failures of Cosmos 133 have been narrowed to entangled thrust vector vanes in the main engines and a single defective approach and orientation thruster. It is agreed to set the unmanned launch of Soyuz s/n 1 for 18 December as a final functional check of all systems. If this is successful, the date will then be set for the manned launch of Soyuz s/n 3 and 4. Flight control will be conducted from Yevpatoria.


17 January 1967 - Manned space plans reviewed. At a meeting of the VPK Military-Industrial Commission and Chief Designers current manned space plans are reviewed.

Additional Details: Manned space plans reviewed.


1967 April - Soyuz 2A (cancelled). The first manned Soyuz flights were an attempt at an 'all up' manned rendezvous, docking, and crew transfer spectacular (eventually accomplished by Soyuz 4 and Soyuz 5). Komarov was the pilot for the Soyuz 1 active spacecraft, which would be launched first. Soyuz 2, with the crew of Bykovsky, Khrunov, and Yeliseyev would launch the following day, with Khrunov and Yeliseyev space-walking to Soyuz 1 and returning to earth with Komarov. Komarov's spacecraft developed serious problems after launch, including the failure of one of the spacecraft's solar panels to deploy. The Soyuz 2 crew were given the order to rendezvous with Soyuz 1 and to try during the planned EVA to unfold the undeployed solar panel. But the launch of Soyuz 2 was cancelled due to heavy rain at the cosmodrome. Low on power and battery reserves, Komarov made an attempt to land the following day. Parachute failure led to the crash of Soyuz 1 and the death of Komarov. After the disaster the Soyuz 2 spacecraft was checked, and the parachute system had the same technical failure. If Soyuz 2 had launched, the docking may have been successful, but then both spacecraft would have crashed on landing, killing four cosmonauts instead of one.
15 October 1967 - Meeting on crew selections for the L3 program.. Attending are Kuznetsov, Gagarin, Khlebnikov. There are three training groups: Soyuz, L1, and L3. Mishin and the MOM are holding up further training of cosmonauts until the VVS agrees to accept Mishin's candidates from TsKBEM. In any case, Mishin's attitude is that 'automation in space is everything. Humans in space are only supposed to monitor the operation of automated systems'. L3 cosmonauts selected by the VVS are: Leonov, Bykovsky, Nikolayev, Popovich, Voronov, Khrunov, Gorbatko, Artyukhin, Kubasov, Makarov, and Rukavishnikov. The official requirements: balanced composition of a crew according to mass requirements (no more than 70 kg weight per cosmonaut), and the ability to monitor fully automated function of the L3. According to official documents, the crew's primary function is to guide the flight, but now Mishin intends that their primary role will be as subjects of psychological and physical observations to establish the adaptation of the human organism to space flight).
15 January 1969 - Soyuz 5. 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. Officially the flight conducted scientific, technical and medico-biological research, checking and testing of onboard systems and design elements of space craft, docking of piloted space craft and construction of an experimental space station, transfer of cosmonauts from one craft to another in orbit.
26 April 1969 - Soyuz program review. The commission considers plans for the rest of the Soyuz production. Spacecraft s/n 14, 15, and 16 are to fly in August 1969, 17 and 18 in November 1969, and 19 and 20 in February-March 1970. Crews selected for the August flights are: for spacecraft 14, Shonin and Kubasov; for 15, Filipchenko, Volkov, and Gorbatko; for 16, Nikolayev and Sevastyanov. Back-ups will be Kuklin, Grechko, and Kolodin. All of the spacecraft will fly 4 to 5 day missions. Spacecraft 15 and 16 will dock and remain together 2 or 3 days to form an 'orbital station'. Experiments planned for the flight are:

  • Visual observation of rocket launch plumes using the Svinets device
  • Film and photography of the spacecraft 15-16 docking from spacecraft 14
  • Demonstration of welding in weightless vacuum conditions using the Vulkan device
  • Demonstration of autonomous navigation by the cosmonauts using a sextant
  • Medium wave radio communications
  • Test of new television sensors for the Soyuz orientation system

Spacecraft 17 through 20 will fly 15 to 16 day missions to demonstrate the new SZhO life support system for the L3, and conduct rendezvous and docking operations using the L3's Kontakt system.

Additional Details: Soyuz program review.


9 October 1969 - Final preparations. The ship's logs/flight plans are reviewed one more time. Tyuratam commander General Kurushin runs through the Svinets ABM experiment again with Shonin and Kubasov - they're ready. The Communist Party has selected Beregovoi and Feoktistov for the trip to the United States in November, ignoring Kamanin's recommendation of Belyayev and Shatalov. Kamanin is not so much against Beregovoi, but he firmly believes that Feoktistov is not worthy of the privilege - he's a degenerate, now on this third marriage..
11 October 1969 - Soyuz 6. Tested spacecraft systems and designs, manoeuvring of space craft with respect to each other in orbit, conducted scientific, technical and medico-biological experiments in group flight. Carried Vulkan welding furnace for vacuum welding experiments in depressurized orbital module. Was to have taken spectacular motion pictures of Soyuz 7 - Soyuz 8 docking but failure of rendezvous electronics in all three craft due to new helium pressurization integrity test prior to mission did not permit successful rendezvous and dockings.

Additional Details: Soyuz 6.


12 October 1969 - Soyuz 7. Tested spacecraft systems and designs, manoeuvring of space craft with respect to each other in orbit, conducted scientific, technical and medico-biological experiments in group flight. Was to have docked with Soyuz 8 and transferred crew while Soyuz 6 took film from nearby. However failure of rendezvous electronics in all three craft due to a new helium pressurization integrity test prior to the mission did not permit successful rendezvous and dockings.

Additional Details: Soyuz 7.


15 October 1969 - Second attempt to dock Soyuz 7 & 8 - rendezvous of Soyuz 6 with Soyuz 8. Following an orbital correction during the night, Soyuz 7 and 8 are expected to be less than 1 km from each other when communications are regained at 9 am. Instead they are 40 km apart. It will require two more orbits over Soviet territory to refine the tracking of the spacecraft and recalculate the necessary rendezvous manoeuvres. By 12:40 they are 1700 m apart and the crews begin the manual rendezvous manoeuvre. Shatalov fires his engines four times, but in the absence of any indication to the pilot of range to the target, he could not get into a position for a safe docking. He withdraws to a safe distance.

Additional Details: Second attempt to dock Soyuz 7 & 8 - rendezvous of Soyuz 6 with Soyuz 8.


16 October 1969 - Landing of Soyuz 6 - further attempts to dock Soyuz 7 and 8. Soyuz 6 lands successfully at 09:52 GM, coming to rest in a vertical position. A recovery helicopter lands 10 minutes later, finding the cosmonauts have already emerged from the capsule. After the landing of Soyuz 6 there are two further attempts to dock Soyuz 7 and Soyuz 8, but they fail due to large errors in the ballistic calculations of the manoeuvres necessary to correct their orbits.
20 October 1969 - Weight loss of Soyuz 6-7-8 crew. The medical reports show all the cosmonauts lost 1.5 to 3.5 kg during the flight (with Filipchenko having the greatest loss). However Kamanin plays tennis with Gorbatko, Shonin, and Volkov just two days after the flight. They show no apparent ill effects of zero-G.
21 October 1969 - Cosmonaut press conference at Baikonur. The cosmonauts hold a press conference on their flight. They are only allowed to speak one of ten prepared responses to questions, despite Kamanin's objections.
22 October 1969 - Cosmonauts arrive in Moscow. The cosmonauts fly from Baikonur to Moscow, escorted by six MiG-21 fighters to Vnukovo airfield, where they receive honours all around, followed by meetings with reporters. Brezhnev was no there - he was on his way to Baikonur to observe the Tyulpan ICBM exercise.
23 October 1969 - Cosmonauts feted at TsKBEM. Traditional meeting between the cosmonauts and the engineers and workers at TsKBEM. They are quizzed on the flight failures, followed by dinner and toasts. Kamanin tells Afanasyev that instead of messing about with the N1-L3, they should build 8 to 10 more Soyuz and fly, fly, fly -- it is the only way to develop reliable systems. The Ministry of Defence needs a long-range plan of sustained flights of 5 to 6 spacecraft per year. All 300 present applaud the speech, except Mishin, who is against a new series of Soyuz spacecraft.
6 November 1969 - Cosmonaut photo sessions.. The day is spent in photo sessions with the cosmonauts in various ministries.
10 November 1969 - Cosmonauts in demand.. Certain generals want the cosmonauts to appear at a meeting. Kamanin is forced to pull them out of follow-up physical examinations for the task.
23 April 1970 - Mishin proposes crews for Soyuz 10 and 11.. Two months after first raising the issue, Mishin has proposed crews for the flights to the DOS station, still planned to occur before the end of the year. Mishin is still pushing Feoktistov, who Kamanin believes is not only seriously ill, but immoral, being on his second wife. Kamanin now has 20 spacecraft crews, but they will have to wait six years or more for a trip to space at the current mission rate. Mishin's proposed DOS crews are as follows: 1 - Shatalov, Yeliseyev, Rukavishnikov; 2 - Shonin, Kubasov, Kolodin; 3 - Volynov, Feoktistov, Patsayev; 4 - Khrunov, Volkov, Sevastyanov.
6 May 1970 - Soyuz 10 / 11 crew discussions.. Meeting on DOS crews. Kamanin will agree to Mishin's proposed crews with the following provisions: 1) Feoktistov is eliminated from the list; 2) Military cosmonauts must be on 3 of the 4 crews, with the overall ratio six military to six civilian cosmonauts. The proposed crews: 1 - Shonin, Yeliseyev, Rukavishnikov; 2 - Leonov, Kubasov, Kolodin; 3 - Shatalov Volkov, Patsayev; 4- Dobrovolsky, Sevastyanov, Voronov. Mishin is opposed to Dobrovolsky and Volkov.
8 February 1971 - Repercussions of Shonin incident.. Kamanin has a meeting with Leonov and Shonin on the KIS incident. Shonin claims he was sober. Mishin calls. He says Khrunov and Shonin were not ready for training anyway; they had to be led by the nose the whole time. He would prefer that Yeliseyev, Kubasov, and Rukavishnikov be assigned to the mission.
11 March 1971 - Major DOS training exercise by second crew.. Leonov, Kubasov, and Kolodin train in the DOS simulator.
22 April 1971 - Soyuz 10. 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.
6 June 1971 - Soyuz 11. 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.


1972 August - Soyuz 12 / DOS 2 (cancelled). Planned first mission to the Salyut DOS 2 space station. Cancelled after it was destroyed during launch.
1973 June - Soyuz 12 / DOS 3 (cancelled). Planned first mission to the Salyut DOS 3 space station (Cosmos 557). Cancelled after it failed in orbit.
15 July 1975 - Soyuz 19 (ASTP). Soyuz 19 initial orbital parameters were 220.8 by 185.07 kilometres, at the desired inclination of 51.80°, while the period of the first orbit was 88.6 minutes. On 17 July the two spacecraft docked. The crew members rotated between the two spacecraft and conducted various mainly ceremonial activities. Leonov was on the American side for 5 hours, 43 minutes, while Kubasov spent 4:57 in the command and docking modules.

After being docked for nearly 44 hours, Apollo and Soyuz parted for the first time and were station-keeping at a range of 50 meters. The Apollo crew placed its craft between Soyuz and the sun so that the diameter of the service module formed a disk which blocked out the sun. After this experiment Apollo moved towards Soyuz for the second docking.

Three hours later Apollo and Soyuz undocked for the second and final time. The spacecraft moved to a 40 m station-keeping distance so that an ultraviolet absorption experiment could be performed. With all the joint flight activities completed, the ships went on their separate ways.


21 July 1975 - Landing of Soyuz 19 (ASTP). Soyuz 19 landed safely at 10:51 GMT, 87 km north-east of Arkalyk, 9. 6 km from its aim point.
27 June 1978 - Soyuz 30. Manned two crew. Docked with Salyut 6. Placed on board the Salyut-6 station, under the Intercosmos programme, a second, international, crew consisting of P.I. Klimuk (USSR) and M. Hermaszewski (Poland) to conduct scientific investigations and experiments.
26 May 1980 - Soyuz 36. Transported the fifth international crew under the INTERCOSMOS programme, comprising V N Kubasov (USSR) and B Farkas (Hungary) to the Salyut-6 station to carry out scientific research and experiments.
3 June 1980 - Landing of Soyuz 35. Soyuz 35 landed at 15:07 GMT, 140 km SE Dzehezkazgan, with the crew of Farkas and Kubasov aboard.
