Tsybin, Paver Vladimirovich (1905-1992) Russian Chief Designer OKB-256 1945-1959. Designs: LL rocketplanes, RS Mach 3 ramjet aircraft, PKA spaceplane. Bureau closed, worked for Korolev on Vostok, Soyuz, AMS and Molniya satellites. Deputy Designer of Buran space shuttle, 1974-1992.

Tsybin's OKB-256 built the rocket-propelled transonic research aircraft LL-1, LL-2, and LL-3 from 1945. On 23 May 1955 they were selected to build the RS air-launched ramjet-powered Mach 3 intercontinental reconnaissance/strike aircraft. In 1957, in response to the USAF Dynasoar project, OKB-256 was one of two aviation bureaux tasked with producing draft project designs for a manned spaceplane. Tsybin's draft project for the PKA gliding spacecraft, undertaken in co-operation with Korolev's OKB-1, was signed by Tsybin on 17 May 1959. Meanwhile a subsonic aerodynamic test vehicle for the RSR was built and first flown on 7 April 1959.

The Tsybin bureau was closed in October 1959. Tsybin and his staff transferred to the Myasishchev bureau in October 1959 (which had its own on-going VKA-23 winged spacecraft project). The Myasishchev bureau was then in turn closed and the staff transferred to Filial 1 of Chelomei's OKB-52 bureau in 1960. Construction of RSR prototypes was stopped in the spring of 1961, with three airframes nearly finished. Tsybin went to work for Korolev at OKB-1. Tsybin's work on the PKA was passed to the Mikoyan bureau and formed the starting point for the design of the Spiral spaceplane. At OKB-1 Tsybin worked on the Vostok, Soyuz, and Soyuz-T manned spacecraft; AMS planetary probes; and Molniya communications satellite. He was finally Deputy Designer of the Buran space shuttle project from 1974 until his death in 1992.

Korolev OKB-1 proposed Vostok ballistic capsule as quickest way to put a man in space while meeting Zenit project's reconnsat requirements. Under project VKA-23 (Vodushno Kosmicheskiye Apparat) Myasishchev OKB-23 proposed two designs, a faceted craft with a single tail, and a dual tail contoured version. Tsybin OKB-256 proposed seven man winged craft with variable wing dihedral. Contracts awarded to all three OKB's to proceed with construction of protoypes. R-7 booster to be used for suborbital launches.

  • PKA Spaceplane Draft Project - . Nation: USSR. Related Persons: Korolev; Tsybin. Spacecraft: PKA. Tsybinís design was called the gliding spacecraft (PKA). The draft project, undertaken in co-operation with Korolevís OKB-1, was signed by Tsybin on 17 May 1959.The piloted PKA would be inserted into a 300 km altitude orbit by a Vostok launch vehicle. After 24 to 27 hours of flight the spacecraft would brake from orbit, gliding through the dense layers of the earthís atmosphere. At the beginning of the descent, in the zone of most intense heating, the spacecraft would take advantage of a hull of original shape (called ĎLapotokí by Korolev after the Russian wooden shoes that it resembled). After braking to 500 to 600 m/s at an altitude of 20 km, the PKA would glide to a runway landing on deployable wings, which would move to a horizontal position from a stowed vertical position over the back of the spacecraft. Control of the PKA in flight was by rocket jets or aerodynamic surfaces, depending on the phase of flight.

1959 September - .
  • PKA Spaceplane Draft Project Completed - . Nation: USSR. Related Persons: Chelomei; Myasishchev; Tsybin. Spacecraft: PKA. The Tsybin bureau was closed down shortly after the draft project was completed. Tsybin and his staff transferred to the Myasishchev bureau in October 1959 (which had its own on-going VKA-23 winged spacecraft project). The Myasishchev bureau was then in turn closed and the staff transferred to Filial 1 of Chelomeiís OKB-52 bureau in 1960. Tsybinís work on the PKA was passed to the Mikoyan bureau and formed the starting point for the design of the Spiral spaceplane.

Spacecraft: Soyuz A. The cosmonaut weds at the TsPK cosmonaut centre, and 80 guests attend. Of the female cosmonauts, only Ponomaryova is not yet married. However the next female flight will be made no earlier than 1965-1966. Tereshkova looks tired after her tour to Southeast Asia - and she's supposed to go to Ghana on 10 January! Korolev claims that the Soyuz schedule, as laid out in the resolution of 4 December 1963, is still realistic. He will have the first Soyuz flight in August 1964 and the second and third in September 1964. Ivanovskiy doesn't believe it will be possible to make any flights until 1965. Korolev and Tsybin disccuss Shcherbakov's design for a rocket-propelled high-altitude glider. This concept was supported by the VVS, but Dementiev was against it and it was killed in the bureaucracy.

  • Baikonur abuzz - . Nation: USSR. Related Persons: Khrushchev; Tsybin; Chertok. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. The cosmodrome is a beehive of activity, not just for the unmanned Voskhod launch, now set for 18 September, but also for the impending visit of Premier Khrushchev on 24 September. Meanwhile Tsybin, Chertok, Kholodkov, and Vinokur are hurriedly implementing and testing changes made to the landing system as a result of the failures at Fedosiya. This will likely slip the mannequin launch to the end of September.

  • Voskhod-2 State Commission - . Nation: USSR. Related Persons: Korolev; Tsybin; Severin. Program: Voskhod. Flight: Voskhod 2. Spacecraft: Voskhod. The first meeting of the State Commission for the Voskhod-2 flight is held. Korolev, Tsybin, Severin, and other testify to the readiness of the spacecraft and booster systems. It is decided to fly the pathfinder mannequin fight on 14-16 February, and the crewed flight on 25-27 February. Kamanin objects that the radio beacon system on Voskhod is less reliable than that on Vostok, as proven on the Voskhod-1 mission.

  • Voskhod 3 - . Nation: USSR. Related Persons: Tsybin; Malinovskiy; Keldysh; Vershinin; Grechko, Andrei; Gagarin; Rudenko. Program: Voskhod. Flight: Voskhod 3; Voskhod 4; Voskhod 5; Voskhod 6. A major programme review is held on plans for Voskhod s/n 5, 6, and 7. Tsybin insists that to conduct all of the experiments requested by the Ministry of Defence will take ten spacecraft and missions, but only five have been authorised. Spacecraft s/n 5 will fly with dogs, on a biosat mission. Spacecraft s/n 6 and 7 are being completed for 15-day flights with two crew, outfitted for artificial gravity experiments and medical and military research. The readiness of the military experiments is very poor, due to the fact that in the past Malinovskiy over and over again prohibited any work on military uses of space, at least until the ideal military platform was developed. It was only on Keldysh's initiative that any preliminary work had been done at all. Kamanin replies to Tsybin that it was not the business of OKB-1 to develop military experiments; this was the concern of the Military of Defence. Yet, Kamanin admits to himself, there is no single organisation within the Ministry that is supervising this work. Later Kamanin takes Gagarin to a meeting with Vershinin and Marshal Grechko. The Marshal is unimpressed with Gagarin's understanding of the issues involved in the issue of whether the VVS or RVSN should handle manned spaceflight. Kamanin resolves not to take cosmonauts to such high-level meetings in the future. Grechko does understand finally how poorly Malinovskiy and his deputies have handled military spaceflight. But Malinovskiy, and his supporters, Marshal Rudenko, and Colonel-General Ponomaryov, will not give up in their effort to prevent the VVS from becoming the responsible organisation for military spaceflight.

  • OKB-1 learns of Gagarin letter - . Nation: USSR. Related Persons: Tsybin; Gagarin; Brezhnev; Korolev. Program: Voskhod; Soyuz. Tsybin has learned through his Ministry of Defence contacts of Gagarin's letter to Brezhnev. He hears that they have criticized the space policy of the Minister of Defence and proposed that the VVS manage Soviet manned spaceflight. The letter also reportedly requests production of a new series of Voskhods to fill in the manned spaceflight gap created by delays in the Soyuz program. Korolev is remarkably unperturbed that he had not heard of the letter, and that Gagarin never said anything to him about it.

  • Soviets losing space race - . Nation: USSR. Related Persons: Brezhnev; Gagarin; Korolev; Tsybin. Program: Voskhod. Flight: Voskhod 3; Voskhod 4; Voskhod 5; Voskhod 6. Brezhnev has not yet had even one hour to glance at Gagarin's letter. Kamanin and the cosmonauts are frustrated - the country has the means - the rockets, the spacecraft designs - to be beating the Americans, but nothing is done due to zero planning, poor organisation and management. Korolev still talks about flying a Voskhod in November, but neither the equipment for the artificial gravity experiment or the 3KD spacecraft for the EVA have been completed. Kamanin hears from Tsybin that Korolev is considering abandoning the Voskhod flights completely so that OKB-1 can concentrate on completing development of the Soyuz...

  • Tsybin birthday party - . Nation: USSR. Related Persons: Tsybin; Korolev; Leonov. Summary: Over 70 space program leaders celebrate Tsybin's 60th birthday at OKB-1. Kamanin and Korolev have cooled down a bit after their argument the day before. Kamanin and Leonov are preparing for a trip to the Soviet Far East on the 28th of December..

  • State Commission - . Nation: USSR. Related Persons: Tyulin; Mishin; Tsybin; Shabarov; Kerimov; Volynov; Shonin; Beregovoi; Shatalov; Pravetskiy; Katys; Keldysh. Program: Voskhod. Flight: Voskhod 3; Voskhod 4; Voskhod 5. Spacecraft: Voskhod. The commission, chaired by Tyulin, with attendance by Mishin, Tsybin, Shabarov, Kerimov, and others considers manned flight plans for 1966. The 20-day dog flight of Voskhod s/n 5 is expected to launch on 22-23 February. Kamanin notes that although he is not against the flight, it has no interest to the military. Launch of Voskhod 3 is set for 20-23 March. Kamanin names his crews for the flight - Volynov/Shonin and Beregovoi/Shatalov as back-ups. Only Pravetskiy objects to these selections, pushing Katys for the prime crew. This settled, Mishin announces he still intends to pursue the artificial gravity experiment on the flights of Voskhod s/n 7 and/or 8. Kamanin informs Mishin that he has requested for more than a year that this experiment be moved to a Soyuz flight - there are 700 kg of new military scientific equipment that has to be flown aboard Voskhod, leaving little room for nothing else.

    It is decided that the flights of Voskhod s/n 5 and 6 will be run from Moscow rather than from the cosmodrome. The state commission will return to Moscow immediately after launch for this purpose. Four groups of staff will follow the flight on four-hour shifts.

    Tyulin, Keldysh, and Mishin want engineer and scientist cosmonauts to be trained for early Soyuz flights. Kamanin agrees, telling them he will submit suitable candidates. The meeting goes well, possibly since in the absence of Korolev the commission is stacked with military representatives - of 17 members, 9 are military.

1966 March 23 - .
  • Cosmos 110 review - . Nation: USSR. Related Persons: Tyulin; Mishin; Tsybin; Volynov; Shonin; Beregovoi; Shatalov. Program: Voskhod. Flight: Voskhod 3. Spacecraft: Voskhod. An OKB-1 review is held, without Tyulin and Mishin, who are at Baikonur supervising launch of a Monlniya satellite and Luna 10. Tsybin leads the meeting. Although the Cosmos 110 flight was successful, there were several deviations: the Zarya antenna did not deploy, the Komar system did not 'digest' after landing, the ion flow sensors were unreliable, and the Signal radio system only functioned in the HF band within the zone of visibility of a tracking station. There was no detectable dangerous radiation at the 900 km apogee of the satellite. The dogs were alive, but uncoordinated in their movement after landing, and showed a loss of calcium in their bones. The flight also showed good functioning of the ECS - the problems seen on the ground could not be duplicated in flight. A new run at IMBP has reached its 16th day with no abnormalities, which clears the system for use on an 18-19 day manned flight. The Voskhod-3 spacecraft has been completed and shipped to Baikonur; the booster has also been delivered and is ready for flight. The crew has completed their flight plans and ship's logs. After completion of the ECS trials (planned for 10 April), Voskhod 3 will be cleared for launch.

    Work on the Svinets experiment continues. It was discovered that the device needs a night horizon, and the absence of a moon in the sky, in order to detect a rocket launch in the infrared band. The designer has been working with the cosmonauts for three months to fix this and problems in reliably operating the equipment. Kamanin estimates it will take 10 to 15 days to rectify these problems. Svinets is a crucial experiment, but in his view the development of the device by the PVO has been poorly managed.

  • Voskhod 3 State Commission - . Nation: USSR. Related Persons: Voronin; Tsybin; Shabarov. Program: Voskhod. Flight: Voskhod 3. Spacecraft: Voskhod. Chief Designer A A Golubev from OKB-154 Voronezh discusses the failure of his engines on the third stage of the Molniya launch on 27 March. He points out that the third stage has operated successfully in 500 stand trials and over 100 flights. It is true there have been seven instances of high-frequency oscillations in test stand runs of the engines, going back to the time of Tereshkova's flight, but these are felt to be due to the test stand propellant feed set-up and would not occur in flight engines. Despite no definite cause having been found for the third stage failure on 27 March, he guarantees his engines ready for flight. Other commission members question his optimism, but finally his guarantee is accepted, dependent on a thorough quality assurance review and certification by military officials responsible for control of the production processes at the factory. Voronin certifies the ECS system for an 18 day flight. Tsybin certifies the readiness of the spacecraft, and Shabarov the readiness of the booster at the launch centre. The absence of Korolev's presence is sorely felt, especially in handling the opposition of Smirnov and Pashkov to the flight. Nevertheless, the order is given for final preparations to proceed, with launch set for 22-28 May. However the confidence of the commission members in standing up to Smirnov is tenuous, and it is clear that any delay into June or July will kill the flight.

  • Soyuz crew manoeuvres - . Nation: USSR. Related Persons: Rudenko; Mishin; Tsybin; Tyulin; Dolgopolov; Yeliseyev; Volkov; Anokhin; Makarov; Grechko; Komarov; Gorbatko; Khrunov; Bykovsky; Voronov; Kolodin; Gagarin; Nikolayev; Smirnov; Ustinov; Malinovskiy. Program: Soyuz. Flight: Soyuz 1; Soyuz 2A; Soyuz s/n 3/4. Spacecraft: Soyuz 7K-OK. Kamanin is back from leave and orients himself. VVS General Rudenko has been visited by Mishin, Tsybin, and Tyulin. They want to replace Kamanin's crews for the first Soyuz mission in September-October with a crew made up of OKB-1 engineers: Dolgopolov, Yeliseyev, and Volkov as the prime crew, Anokhin, Makarov, and Grechko as back-ups. Kamanin believes this absurd proposal, made only three months before the planned flight date, shows a complete lack of understanding on the part of OKB-1 management of the training and fitness required for spaceflight. Kamanin has had eight cosmonauts (Komarov, Gorbatko, Khrunov, Bykovsky, Voronov, Kolodin, Gagarin, and Nikolayev) training for this flight since September 1965. Yet Mishin and Tyulin have been shopping this absurd proposal to Smirnov, Ustinov, and Malinovskiy, who do not know enough to reject it.

1966 July 12 - .
  • Soyuz crews - . Nation: USSR. Related Persons: Tsybin; Mishin. Program: Soyuz. Spacecraft: Yastreb. Kamanin meets with Tsybin (Mishin being unavailable on 'command' activities). For over two hours they argue about Soyuz crew plans. Kamanin finds it absurd that OKB-1 thinks they can turn engineers into spacecraft commanders with two to three months training, when it takes the VVS two to four years. He also declares himself categorically opposed to sending crew out on spacewalks with serious health defects. He tries to impress on Tsybin that it will be fatal to send men into space without medical screening, centrifuge and zero-gravity screening and training. It would be insane to send men out into open space to conduct work without training on representative equipment, dressed in a spacesuit, in a zero-G aircraft. He declares himself ready to train candidates selected by the Academy of Science and MOM as cosmonauts, but only on a sensible and professional basis, not a crash program. Kamanin senses that Tsybin realises the fallacy of MOM's position, but he is only following the orders of Mishin, Tyulin, and Korolev before them. He promises to discuss the matter again with Mishin.

1966 July 26 - .
  • Soyuz hatch problem - . Nation: USSR. Related Persons: Sharafutdinov; Shcheglov; Skvortsov; Komarov; Khrunov; Gorbatko; Mishin; Tsybin; Severin; Alekseyev, Semyon; Anokhin; Yeliseyev; Smirnov. Program: Soyuz. Flight: Soyuz 1; Soyuz 2A; Soyuz s/n 3/4. Spacecraft: Soyuz 7K-OK; Yastreb. Training of the new cosmonaut cadre is reviewed. English language courses are proving to be a particular problem. There have been some potential washouts - Sharafutdinov has done poorly in astronomy, Shcheglov suffered an injury at the beach, Skvortsov damaged his landing gear on a MiG-21 flight.

    At 15:00 a major review is conducted, with Komarov, Khrunov, Gorbatko, Kamanin, and other VVS officer meeting with OKB-1 leaders Mishin, Tsybin, Severin, Alekseyev, Anokhin, and other engineers. Film is shown of the difficulties in the zero-G aircraft of cosmonauts attempting to exit from the 660 mm diameter hatch. In four sets of ten attempts, the cosmonaut was only to get out of the hatch half the time, and then only with acrobatic contortions - the inflated suit has a diameter of 650 mm, only 10 mm less than the hatch. Mishin finally concedes the point. But installation of the hatch in Soyuz s/n 3 and 4 is not possible - the spacecraft are essentially complete, and to add the hatch would delay their flight 6 to 8 months. Then Mishin makes the astounding assertion that Gorbatko and Khrunov are not adequately trained to be engineer-cosmonauts, and without this he will not allow them into space. He suggests OKB-1 engineers Anokhin and Yeliseyev instead. After outraged response, Severin finally sinks this suggestion by pointing out that no space suit has been prepared for Anokhin, and that it will take two to three months to make one. Kamanin is astounded that Mishin has pushed Anokhin all the way up to Smirnov and the VPK without even knowing he could not possibly fly due to this restriction. It again points out their poor management. Finally Mishin agrees that spacecraft s/n 5 and 6 and on will have 720 mm hatches. The ECS for the suits for those missions will have to be changed from a backpack configuration, with the equipment rearranged around the waist of the cosmonaut. The crews for the flight will be an experienced VVS pilot cosmonaut as commander, and (Kamanin realizes he may have to concede) a VVS engineer as flight engineer cosmonaut. They will have to complete training by 1 October 1966.

  • Beregovoi pushed for Soyuz mission - . Nation: USSR. Related Persons: Mishin; Rudenko; Beregovoi; Gagarin; Anokhin; Khrunov; Volynov; Shonin; Tsybin; Tyulin; Burnazyan; Keldysh; Malinovskiy; Zakharov; Krylov; Vershinin. Program: Soyuz; Voskhod. Flight: Voskhod 3; Soyuz 1; Soyuz 2A; Soyuz s/n 3/4. Spacecraft: Soyuz 7K-OK; Yastreb. Mishin, Rudenko, and others have met with Beregovoi and support his selection as commander for the first Soyuz mission. Kamanin does not believe he is fit for the assignment, due to his age, his height and weight (that are the limit of the acceptable for the Soyuz). Gagarin reports that during a visit to OKB-1 the day before, he discovered that they were still going all out to prepare their own crews and train their own cosmonauts for Soyuz flights. Kamanin reassures him that the full power of the VVS, the General Staff, and the Ministry of Defence is behind the position that only VVS pilots will command the missions. Mishin is gloating over the latest spacesuit tests. Khrunov tried exiting from the Soyuz hatch in the Tu-104 zero-G aircraft. Using his full dexterity and strength, he had more success than in earlier tests. But Kamanin notes that designing a spacecraft hatch only 10 mm wider than the cosmonaut is hardly the basis for practical spaceflight or training. Later Kamanin plays tennis with Volynov and Shonin. Their Voskhod 3 flight is still not officially cancelled. They have been fully trained for the flight for months now, but no go-ahead is given. On Saturday, Tsybin presents to the General Staff OKB-1's concept for training of engineer cosmonauts. Tyulin, Burnazyan, and Keldysh have approved the plan, except they have substituted VVS engineer cosmonauts for those from OKB-1 for the first Soyuz flights. So this is the result of months of controversy - a position that there is no fundamental opposition to cosmonaut candidates from OKB-1. Kamanin sees the absolute need for his draft letter to be sent from the four Marshals (Malinovskiy, Zakharov, Krylov, and Vershinin) to the Central Committee. Mishin continues to "assist" the situation - it has been two weeks since he promised to submit the names and documentation for his candidates to the VVS, and he has done nothing.

  • Showdown on spacesuits - . Nation: USSR. Related Persons: Litvinov; Mishin; Tsybin; Bushuyev; Severin; Komarov; Bykovsky; Nikolayev; Gagarin; Khrunov; Gorbatko; Anokhin; Yeliseyev; Alekseyev, Semyon. Program: Soyuz. Flight: Soyuz 1; Soyuz 2A; Soyuz s/n 3/4. Spacecraft: Soyuz 7K-OK; Yastreb. At a meeting at LII MAP Zazakov, Litvinov, Mishin, Tsybin, Bushuev, Severin, Alekseyev, and Komarov spar over the hatch and spacesuit problem. Severin only agrees to modifying the ECS under immense pressure, but the modified suit will not be ready until November. Severin could not get Mishin to agree to an increased hatch diameter from Soyuz s/n 8 - Mishin will only "study the problem". An arrangement of the ECS around the waist of the cosmonaut is finally agreed. Mishin and Litvinov categorically rejected any modification of the hatch in the first production run of Soyuz.

    In turn, Factory 918 insisted on a final decision on Soyuz crews. They cannot build 16 of the custom-built spacesuits for all possible candidates for the flights (8 from VVS and 8 from OKB-1). It was therefore agreed that the commanders of the first two missions would be Komarov and Bykovsky, with Nikolayev and Gagarin as their backups. It was finally decided to assume that the other crew members would be either Khrunov and Gorbatko from the VVS, or Anokhin and Yeliseyev from OKB-1.

  • Soyuz simulators still incomplete - . Nation: USSR. Related Persons: Darevskiy; Tsybin. Program: Soyuz. Spacecraft: Soyuz 7K-OK. Darevskiy now reports that the 7K-OK will not be finished until the end of October at the earliest. Poor quality optic systems and unreliable equipment from OKB-1 are blamed. Tsybin promises to resolve all issues, with OKB-1-providing equipment within a week

  • Soyuz State Commission - . Nation: USSR. Related Persons: Mnatsakanian; Tsybin; Mishin; Smirnov. Program: Soyuz. Flight: Voskhod 3; Soyuz 1; Soyuz 2A. Spacecraft: Soyuz 7K-OK. The investigative committees unanimously concluded that the problems with Cosmos 133 were not due to any fundamental design defects, but rather poor pre-launch quality control and testing which did not reveal the problems. All Soyuz 7K-OK spacecraft will be reworked to remove the problems by 15 December. The go-ahead is given to launch Soyuz s/n 1 between 15-18 December. Only Mnatsakanyan, designer of the automatic docking system, objects to the idea of a single spacecraft test flight. Tsybin reports that over four hundred system and subsystem qualification tests have been completed on Soyuz. However some vacuum tests in the TBK-60 chamber, and tests of the back-up parachute system and emergency recovery system will not be completed until 10 January 1967. Tsybin is ordered to accelerate the work so that the entire spacecraft is qualified for manned flight by 5 January. Mishin states that, assuming the flight of s/n 1 is successful, the manned flight of Soyuz s/n 3 and 4 can begin by 29 January 1967. Kamanin is reminded that Smirnov's cancellation of the Voskhod 3 launch in June, based on the promise that Soyuz would fly by October, has instead resulted in almost two years without a Soviet manned spaceflight.

    Later Kamanin learns that Malinovskiy is dying of cancer and will not return to work. Kamanin prays for his own health in the remaining five to seven years until his retirement. He will be able to retire peacefully only once Soviet voyages to the lunar surface have become routine.

Inclination: 51.5000 deg. Period: 88.30 min. Protoype Soyuz 7K-L1 manned circumlunar spacecraft. There are high winds for the L1 launch, 15-17 m/s. The official limit is 20 m/s, but Chelomei wants to scrub the launch if winds go over 15 m/s. Nevertheless the launch proceeds in 17-18 m/s winds and the L1 reached earth orbit. However the Block D translunar injection stage failed to fire (ullage rockets, which had to fire to settle propellants in tanks before main engine fired, were jettisoned prematurely). The failure is blamed on Mishin and has Tsybin seething in anger. Mishin is disorganised and has made many mistakes. Spacecraft burned up two days later when orbit decayed. Later in the day comes the news the RTS has to be replaced on one of the Soyuz 1/2 spacecraft. This will have a 3 to 4 day schedule impact, and push the launch back to 15-20 April. The crews arrive the same day for the upcoming Soyuz launch.

  • Review of Soyuz trainer status. - . Nation: USSR. Related Persons: Mishin; Feoktistov; Tsybin. Program: Lunar L1; Soyuz. Spacecraft: Soyuz 7K-OK; Soyuz 7K-L1. The Soyuz simulator has not been functional for three months -- entirely the fault of Mishin and Tsybin. The L1 trainer has not been finished, and the autonomous navigation system has not completed development. There are two prototype electronic computers at TsKBEM, but they are not complete and don't work. The first L1 spacecraft was to fly in May, but it is now clear it won't be ready until September at the earliest. There will be no manned lunar flyby for the fiftieth anniversary of the October Revolution as was ordered by the Party. Additional Details: here....

  • Soyuz 9 Day 18 - . Nation: USSR. Related Persons: Mishin; Nikolayev; Sevastyanov; Kerimov; Afanasyev, Sergei; Karas; Bushuyev; Tsybin. Program: Soyuz. Flight: Soyuz 9. Spacecraft: Soyuz 7K-OK. Final Landing Commission meeting is held. The primary landing site is 50 km west of Karaganda. Visibility there is 10 km, winds 6-10 m/s. Mishin wants to land 50 km further wesst, near a city with passenger train service. It is finally agreed to land there, at 71 deg 31' E, but that will mean that an emergency ballistic re-entry (in the event of a guidance system failure) would bring the capsule down in the Aral Sea. That in turn means additional recovery forces, consisting of three amphibious vehicles, three helicopters, five naval cutters, and 15 scuba divers have to be alerted and prepared. The Politburo approves the landing, and the plan to fly the cosmonauts to Chkalovsky Airfield, followed by ten days in the hospital. Mishin and Kerimov discussed having the traditional cosmonaut greeting at Vnukovo Airport, but they'll have to forget such extravaganzas in the years to come, when only long-duration missions are planned. Meanwhile the crew is well, preparing for landing. They secure the BO living module, stow items in the SA re-entry vehicle that are to be returned to earth. There is a communications pass at 08:00 to 08:30. Afanasyev, Karas, Chertok, Bushuyev, Tsybin, and other members of the State Commission now arrive at Yevpatoriya.
