Severin Chronology


1964 July 20 - .
  • Voskhod training - . Nation: USSR. Related Persons: Volynov; Katys; Yegorov; Severin. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. Volynov, Katys, and Yegorov conduct tests in the spacecraft for the first time at the cosmonaut training centre. The cabin is extremely cramped, even without spacesuits, and Katys does not fit in the standard seat, his head sticks 3 to 4 cm beyond the moulded head rest. Gay Severin promises to prepare an individual seat liner for Katys. Kamanin briefs the crew on the status of tests of the Voskhod soft landing system and an incident in the recovery of a Zenit reconnaissance satellite capsule, which was the same type as Voskhod and Vostok. It descended in the Ural mountains, landed on a 30 degree slope, and rolled 300 m before coming to a halt. Due to the unreliability of Voskhod, it is proposed that each crew member be provided with a special mask to protect the face and throat. The Academy of Science has not yet provided the promised experiments to be conducted in-flight. On the other hand, the medical experiments and observations have already been agreed.,

1965 February 6 - .
  • 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.

1965 March 16 - .
  • Voskhod-2 state commission - . Nation: USSR. Related Persons: Belyayev; Leonov; Korolev; Severin; Kuznetsov. Program: Voskhod. Flight: Voskhod 2. Spacecraft: Voskhod; Berkut. Korolev, Severin, Kuznetsov, and Kamanin certify the readiness of the booster and spacecraft, the airlock and spacesuit, the astronauts, and the recovery forces. Roll-out to the pad is set for the morning of 17 March, with launch on 18 or 19 March. In the evening the recovered Zenit-4 capsule arrives at Baikonur and is examined by the astronauts. The rate of rotation never exceeded 40 - 100 degrees/second, well within the tolerance of both the crew and the parachute deployment system.

1966 July 20 - .
  • Heated exchange with Mishin - . Nation: USSR. Related Persons: Mishin; Severin; Darevskiy; Komarov. Program: Soyuz. Flight: Soyuz 1; Soyuz 2A; Soyuz s/n 3/4. Spacecraft: Yastreb. Kamanin and VVS officers spend more than two hours in a heated exchange with Mishin and his staff at OKB-1. Mishin is attacked for delays in completion of Soyuz; his demand that OKB-1 cosmonauts be trained in VVS zero-G aircraft without any agreement on this having been reached; the lack of work on spacesuits for the Soyuz flights by Severin; and above all his "illegal" training of his own cosmonauts. Mishin responds with wild attacks against the competence of Kamanin's cosmonauts, saying that his engineers could better guide a spacecraft to a docking than Kamanin's pilots. Finally things cool down, and Mishin agrees to submit to Kamanin a list of OKB-1 candidates for cosmonaut training within two to three days. Kamanin agrees to consider how they may be prepared for flight on a two-month schedule.

    Later Kamanin's group visits Darevskiy at MAP and reviews the status of Soyuz trainer completion. He promises to have them completed by the end of August. Finally Kamanin confronts Komarov over statements he made in Japan. Komarov admits telling the world press that the Soviet Union will, at the scheduled time, fly an automated spacecraft around the moon and return it to earth, to be followed by a dog flight, then a manned circumlunar flight. Kamanin has already had the Central Committee and Soviet Ministers calling him about this unauthorised disclosure.


1966 July 25 - .
  • VVS Victory on Soyuz crew issue - . Nation: USSR. Related Persons: Tyulin; Mishin; Malinovskiy; Khrunov; Gorbatko; Voronov; Kolodin; Severin. Program: Soyuz. Flight: Soyuz 1; Soyuz 2A; Soyuz s/n 3/4. Spacecraft: Yastreb. Tyulin advises Kamanin that Ustinov has instructed Mishin to accept that Soyuz spacecraft will be commanded by a VVS pilot cosmonaut, with OKB-1 providing cosmonauts for the engineering support role. Mishin is to immediately send four candidates from OKB-1 to Kamanin for cosmonaut training. Kamanin feels this is only a 50% victory, and vows to accelerate submission of the letter from Malinovskiy to the Central Committee, demanding that the support cosmonaut seats also be filled by trained VVS engineer cosmonauts (e.g. Khrunov, Gorbatko, Voronov, and Kolodin). Meanwhile spacesuit designer Severin informs Kamanin that OKB-1 has insisted that the outer hatch of Soyuz will remain at 660 mm diameter, even though he has told them for a long time that the minimum diameter for a cosmonaut in spacesuit with a life support system backpack is 700 mm. Kamanin agrees to support him, but notes the change can only be made in later spacecraft; it is too late to change the first production run.

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.

  • VPK Meeting - L1 delays - . Nation: USSR. Related Persons: Vershinin; Chelomei; Mishin; Voronin; Severin. Program: Lunar L1. Flight: Soyuz 7K-L1 mission 1. Spacecraft: Soyuz 7K-L1. Marshal Vershinin attends the meeting, where it is revealed that all systems in development - Chelomei's, Mishin's, Voronin's, Severin's, and others - are seriously behind schedule. The first unmanned circumlunar test of the L1 was to be made by 15 April 1967, but it seems unlikely it will even be completed by the end of 1967.

1966 August 5 - .
  • 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.


1966 September 7 - .
  • Cosmonaut group leaders - . Nation: USSR. Related Persons: Volkov; Grechko; Kubasov; Popovich; Belyayev; Severin; Khrunov; Gorbatko; Anokhin; Yeliseyev; Pravetskiy. Program: Soyuz; Almaz. Flight: Soyuz 1; Soyuz 2A. Spacecraft: Soyuz 7K-L1; Soyuz VI; Almaz OPS; Yastreb. 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.

1968 March 20 - .
  • Lunar spacesuit review. - . Nation: USSR. Related Persons: Severin; Mishin. Program: Lunar L3. Spacecraft: Krechet; Orlan; LK; Luna Ye-8. Meeting with Gay Ilyich Severin. Two spacesuits are being developed for the L3 program: the Krechet-94 and Orlan. Both have been in development for two years. The Krechet-94 will allow six hours of lunar surface activity, the Orlan, 2.5 hours. Both weigh about 90 kg. There are consumables for a total of 52 hours of life support in the LK and the LT Lunar Cart. Kamanin feels the suits are too heavy, due to Mishin's demand for a 5 km range from the LK over a three day traverse with the LT. Severin could have instead developed the spacesuit used by Leonov to have a four hour autonomous operation, but Mishin insisted on doubling of the capacity.

1968 December 16 - .
  • Lunar Soviet. - . Nation: USSR. Related Persons: Mishin; Severin. Program: Lunar L1; Lunar L3. Spacecraft: Soyuz 7K-L1; Krechet. In a four-hour meeting, a number of issues are dealt with. First point was military control of the KIK control centre for lunar missions. A civilian mission control centre is requested. Next, the issue of recovery of L1 and L3 capsules in the Indian Ocean. The re-entry corridor within which landings might occur is 6000 km long and 100 km wide, stretching from Antarctica to India. To cover it will require 20 naval vessels, each with a helicopter, and 10 An-22 or Tu-95 long-range maritime reconnaissance and relay aircraft. Total cost: 600 million roubles. As Kamanin sees it, all this is due to Mishin's inability to design spacecraft capable of precision landing that also incorporates the landing and recovery aids requested by the VVS. Kamanin notes in his diary violent criticism of Mishin's disregard for the safety of the cosmonaut crews, development of crew-associated items at the last minute, unrealistic schedules and expectations, etc. etc. Severin reports that the lunar space suit he is designing will support the cosmonaut for three days, during walks extending 5 km. To do this requires a bulky suit weighing 100 kg. Kamanin disagrees, saying what is needed is to develop a simple and safe approach for the first landing, with a minimum programme for the cosmonaut - not the fantastic schemes of Mishin.

1968 December 26 - .
  • Heated arguments over technical approach of Soviet space systems - . Nation: USSR. Related Persons: Shatalov; Beregovoi; Severin; Mnatsakanian; Mishin. Program: Lunar L1; Soyuz; Almaz. Flight: Apollo 8. Spacecraft: Soyuz 7K-OK; Soyuz 7K-L1; Soyuz 7K-LOK; Soyuz 7K-S; Almaz OPS; Soyuz OB-VI; Soyuz VI. The training for the Soyuz 4 and 5 flights was completed last night. Today the crews undergo medical tests and start preparation of their flight logs/flight plans. On the return flight to Moscow Shatalov, Beregovoi, Severin, Kamanin, and Mnatsakanian get into a heated argument. The cosmonauts attack Mnatsakanian's Igla automated docking system. It limits docking manoeuvres to periods when the spacecraft are flying over the Soviet Union due to the requirement for ground stations to receive live television. The Americans worked only on the Apollo spacecraft for the last two to three years, while the Soviets have divided their efforts on no less than five spacecraft types: the L1, L3, Soyuz, Soyuz VI, and Almaz. This is all Mishin's fault...

  • ECS technology review. - . Nation: USSR. Related Persons: Keldysh; Voronin; Severin; Gazenko. Program: Salyut. Spacecraft: Salyut 1; MKBS; Aelita. Keldysh heads a review of spacecraft environmental control system development. The work of the IMBP is not well organised. They have been developing systems for eight years with no concrete results. G I Voronin is responsible for oxygen regenerator and thermal regulation systems; G I Severin, for space suits; O G Gazenko for biosensors, medicines, and space food. Two problems need to be solved: to understand and counter the effects of zero gravity on the human organism; and to develop a reliable environmental control system with a guaranteed life of two to three years. Keldysh declares that in the next five to ten years the Soviet Union will not fly space stations with artificial gravity. Therefore, due to the inevitable deterioration of the human body in zero gravity, crews will have to be rotated every 30 to 60 days. Development must continue with an eye to supporting eventual lunar bases and manned expeditions to Mars.

1971 July 4 - . LV Family: N1. Launch Vehicle: N1.
  • Soyuz 11 failure investigation - . Nation: USSR. Related Persons: Tereshkova; Dobrovolsky; Patsayev; Volkov; Severin. Program: Lunar L3; Salyut. Flight: Soyuz 11. Spacecraft: Soyuz 7KT-OK; Soyuz 7K-T. This was a very difficult time for TsKBEM. All work at the bureaus came to a complete halt after the loss of Soyuz 11 and N1 6L. Simultaneous expert commissions investigated the loss of N1 6L and Soyuz 11. TsKBEM was seen as responsible for every failure. A virtually legal process ensued to fix guilt. Every design decision was examined and questioned. Additional Details: here....
