  • Voskhod The Voskhods were adaptations of the single place Vostok spacecraft meant to conduct flights with up to three crew and for space walks in advance of US Gemini program. Work on the 3KV and 3KD versions of the basic Vostok spacecraft began with the decree issued on 13 April 1964. In order to accommodate more than one crew, the seats were mounted perpendicular to the Vostok ejection seat position, so the crew had to crane their necks to read instruments, still mounted in their original orientation. The Elburs soft landing system replaced the ejection seat and allowed the crew to stay in the capsule. It consisted of probes that dangled from the parachute lines. Contact with the earth triggered a solid rocket engine in the parachute which resulted in a zero velocity landing. More...

Yegorov Chronology


1964 May 26 - .
  • Voskhod Cosmonaut Training Group selected. - . Nation: USSR. Related Persons: Benderov; Lazarev; Polyakov, Boris; Sorokin; Yegorov. The group was selected toprovide payload specialists and physicians for Voskhod spaceflights.. Qualifications: Engineers, scientists, or physicians nominated by their parent organizations; under 40 years of age; under 170 cm tall; under 70 kg in weight.. In 1963 it was decided to fly the Voskhod multi-seat spacecraft. There followed a chaotic struggle between the commander of the Soviet cosmonaut team, Kamanin, and leaders of other military and civilian scientific and engineering organisations over who would fly on these missions. The training group for the first Voskhod 3-seat mission included:

  • Voskhod passenger candidates - . Nation: USSR. Related Persons: Lazarev; Yegorov; Polyakov; Sorokin; Moskalyov; Katys. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. After screening the flight candidates have been boiled down to four: Lazarev, Yegorov, Polyakov, and Sorokin. Moskalev and Katys are the remaining scientist-passenger candidates. Kamanin believes Katys, with a doctorate in technical sciences, is the better candidate and definitely superior to any of the OKB-1 engineer candidates.

1964 May 29 - .
  • Voskhod passenger candidates - . Nation: USSR. Related Persons: Lazarev; Yegorov; Polyakov; Sorokin; Katys. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. Summary: Following final review, the General Staff ordered Lazarev, Yegorov, Polyakov, Sorokin, and Katys to enter training for flight aboard the Voskhod spacecraft..

1964 July 2 - .
  • Voskhod and Soyuz crewing - . Nation: USSR. Related Persons: Benderov; Polyakov; Volynov; Katys; Komarov; Yegorov; Sorokin; Lazarev; Feoktistov; Titov; Beregovoi. Program: Voskhod; Lunar L1. Flight: Voskhod 1; Soyuz A-4. Spacecraft: Voskhod; Soyuz A. Benderov has been washed out of training after haemorrhaging excessively during centrifuge training, and Polyakov after reacting poorly to the barometric chamber. This leaves only seven cosmonauts in training for the first mission: Volynov, Katys, Komarov, Yegorov, Sorokin, Lazarev, and Feoktistov. The first six are qualified for flight, but Feoktistiov cannot be admitted for parachute or flight training; his visual acuity is only 0.3. Later the cosmonaut party collective meets to take up the problem of Titov. He has made many errors: he drives and flies too fast, he has bad marital relations. But he is known not only to the entire country, but to the whole world. To disgrace him would not reflect only on him, but on all of the cosmonauts and the Soviet Union. Therefore it is finally decided not to take any public action, but to switch him and Beregovoi in the training order for the fourth Soyuz flight.

    Later Finogenov, head of the VVS range at Vladimirovka, informs Kamanin that flight trials of the new combination parachute/soft landing system will be delayed at least two weeks after the failure of one of the parachute canopy rings in static test.


1964 July 6 - .
  • Voskhod crews selected. - . Nation: USSR. Related Persons: Volynov; Katys; Yegorov; Komarov; Feoktistov; Sorokin; Lazarev; Belyayev; Leonov; Khrunov; Gorbatko. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. Kamanin select Volynov, Katys, and Yegorov as the prime crew for the Voskhod flight. Komarov, Feoktistov, and Sorokin will be the backup crew. Lazarev will serve as reserve for both crew physician position. The VVS leadership approves the selection. For the first space walk (the flight designated Vykhod at the time), Belyayev, Leonov, Khrunov, and Gorbatko are in training. All want to be first, but Kamanin finds Leonov and Khrunov to have the best analytical minds, to be able to get themselves out of a jam if something goes wrong. He selects Belyayev and Gorbatko to be trained as spacecraft commanders for the missions.

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.,

1964 August 12 - .
  • Voskhod State Commission - . Nation: USSR. Related Persons: Korolev; Volynov; Katys; Lazarev; Yegorov; Komarov; Feoktistov; Sorokin. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. The readiness of two crews is certified (the prime crew of Volynov, Katys, and Yegorov and backup crew of Komarov, Feoktistov, and Sorokin). Korolev presses for Feoktistov to be included in the prime crew, citing his unequalled technical knowledge of the spacecraft. Kamanin and the VVS doctors oppose this, citing his poor medical condition which makes him uncertifiable for flight. A very heated discussion ensues, with the final decision to continue training all seven cosmonauts, with the first candidates for flight being Volynov, Katys, and Yegorov, with Komarov, Lazarev, and Sorokin being reserve cosmonauts. The question of Feoktistov's flight certification will be taken up by a special panel of physicians.

1964 August 26 - .
  • Voskhod crews - . Nation: USSR. Related Persons: Katys; Yegorov; Korolev. Program: Voskhod. Flight: Voskhod 1; Voskhod 2. Spacecraft: Voskhod; Berkut. Composition of the crew for Voskhod continues to be debated intensively. There has been talk of the medical unsuitability of Katys and Yegorov. Later Kamanin discusses progress with the Vykhod mission based on their work at Factory 918 and LII. Many technical details have to be worked out -- movement in open space, the space suit, airlock, communications, etc. The work is in two steps: first to solve simply doing spacewalk, and then how to control and manoeuvre the spacecraft when a cosmonaut is outside. Korolev seems to think that enthusiasm will solve all problems, but Kamanin is concerned of the demonstrated unreliability of Korolev's Luna, Mars, and Molniya unmanned spacecraft.

1964 August 31 - .
  • Katys deleted from Voskhod prime crew. - . Nation: USSR. Related Persons: Katys; Yegorov; Feoktistov. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. It is discovered that Katys has a brother and sister living in Paris, a fact he did not disclose during the selection process. They left for Paris in 1910, 16 years before Katys was even born. But together with the fact that his father was executed by the Soviet state, it makes him unsuitable to be a cosmonaut. Yegorov and Feoktistov are making serious efforts to be appointed to the crew. Yegorov did poorly in zero-G training and Feoktistov is physically unqualified. Meanwhile TASS, APN, and other Soviet newspapers are stubbornly pursuing information about the crew for the forthcoming flight. Film biographies and press kits are being made of all of the candidates, so that the information can be released once the final crew - whoever they are - are in orbit. But this violation of secrecy disturbs Kamanin.

1964 September 14 - . LV Family: N1; Proton; R-7; UR-700.
  • Voskhod abort system - . Nation: USSR. Related Persons: Korolev; Krylov; Feoktistov; Komarov; Volynov; Lazarev; Yegorov. Program: Voskhod; Lunar L1; Lunar L3. Flight: Voskhod 1. Spacecraft: Voskhod; LK-1. Kamanin reviews the Voskhod abort system with Korolev. Up to T+27 seconds, there is no possibility of saving the crew in the event of a booster failure; from T+27 seconds to T+44 seconds, escape would be difficult, but is possible; and from T+44 seconds to T+501 seconds abort should be possible, with the capsule landing on Soviet territory. Afterwards, Korolev speaks with Kamanin secretly and privately. Korolev reveals that he has discussed a greater VVS role in space with Marshal Krylov, but that Krylov is adamantly opposed to the VVS assuming such a mission. Korolev is seeking a resolution from the Communist Party that will authorise him to develop a manned lunar flyby and landing system using his N1 booster. He believes that Chelomei's UR-500 booster will not have sufficient payload to mount a manned flyby - a docking in low earth orbit will be required. But Chelomei has rejected the use of docking, and is even designing his UR-700 to allow a lunar landing without the use of docking.

    Finally Korolev gets to the purpose of the secret meeting. He wants Feoktistov to be aboard Voskhod 1, despite the opinion of Kamanin and the physicians. Kamanin reiterates that the most qualified crew would be Komarov, Volynov, and Lazarev; and if he gives in on Feoktistov, then Komarov, Feoktistov, Lazarev. But Korolev is opposed to Lazarev, and insists that the crew should be Komarov, Feoktistov, and Yegorov. From Kamanin's point of view this is flying a space mission with two invalids aboard. Lazarev is a qualified and fit flight surgeon, a qualified pilot as well as a physician with 15 years of research experience in aviation medicine. Korolev is adamant that the two passengers should be civilian, not military. No agreement is possible.


1964 September 24 - .
  • Voskhod crew ready - . Nation: USSR. Related Persons: Volynov; Komarov; Katys; Feoktistov; Yegorov; Sorokin; Lazarev; Gagarin; Belyayev; Khrunov; Khrushchev. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. Kamanin arrives at Baikonur. All is ready for the Voskhod launch, except the spacecraft. Kamanin conducts a final readiness review with Volynov, Komarov, Katys, Feoktistov, Yegorov, Sorokin, and Lazarev. He tells them that every one of them must do his utmost to be physically and psychologically ready for the flight, since the final crew selection will not be made until 2 or 3 days before the launch. Gagarin, Belyayev, and Khrunov are at the cosmodrome, where they are showing the Vykhod spacecraft to Khrushchev. Later Kamanin discusses the crew selection with the military leadership. The top brass have no interest in space and seem to be ready to give in to Korolev. This invalidates everything Kamanin was worked for in terms of establishing a systematic method of cosmonaut selection, training, and crew selection.

1964 October 4 - .
  • Voskhod crews arrive - . Nation: USSR. Related Persons: Volynov; Katys; Komarov; Feoktistov; Yegorov. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. At 15:30 the Voskhod cosmonauts arrive aboard an An-10 at Baikonur and are greeted by Korolev and others. Although they have not been told officially, Kamanin is sure that Volynov and Katys have heard that the State Commission finally selected Komarov, Feoktistov, and Yegorov for the flight. In the evening Kamanin plays tennis with the flight crew and is surprised - Yegorov and Feoktistov play well, and Komarov played poorly.

1964 October 9 - .
  • Cosmos 47 teardown - . Nation: USSR. Related Persons: Korolev; Tyulin; Rudenko; Tkachev; Komarov; Yegorov; Feoktistov. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. At 10:00 Korolev, Tyulin, Rudenko, Tkachev, and other leaders examine the capsule. The condition of the parachute, and capsule exterior and interior show how well the soft landing system functioned. Then they examine the Voskhod s/n 3 which will be sued for the manned flight. The crew of Komarov, Yegorov, and Feoktistov take their place in the cabin, and Korolev and Kamanin examine the cramped accommodations and ask Komarov questions to verify his understanding of the ship's controls. For an hour from 16:00 the crew is interviewed by news correspondents. After the interview, the crew plays tennis for the benefit of photographers. Afterwards post-flight examinations are discussed. A suggestion that the crew spends three nights in a hospital after the flight is rejected. Instead they will spend three nights in the cosmonaut's quarters at Baikonur, under medical observation. Finally, the State Commission meets to verify the crew selection. The session is filmed and recorded for later use by the press.

1964 October 12 - . 07:30 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC1. LV Family: R-7. Launch Vehicle: Voskhod 11A57. LV Configuration: Voskhod 11A57 R15000-04.
  • Voskhod 1 - . Call Sign: Rubin (Ruby ). Crew: Feoktistov; Komarov; Yegorov. Backup Crew: Katys; Lazarev; Volynov. Payload: Voskhod 3KV s/n 3. Mass: 5,320 kg (11,720 lb). Nation: USSR. Related Persons: Korolev; Rudenko; Tyulin; Gagarin; Feoktistov; Komarov; Yegorov; Katys; Lazarev; Volynov. Agency: Korolev. Program: Voskhod. Class: Manned. Type: Manned spacecraft. Flight: Voskhod 1. Spacecraft: Voskhod. Duration: 1.01 days. Decay Date: 1964-10-13 . USAF Sat Cat: 904 . COSPAR: 1964-065A. Apogee: 336 km (208 mi). Perigee: 178 km (110 mi). Inclination: 64.7000 deg. Period: 89.60 min. 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....

  • Preparations for return to Moscow - . Nation: USSR. Related Persons: Malinovskiy; Komarov; Yeliseyev; Yegorov. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. The Voskhod 1 crew memorise and rehearse the speeches they will deliver to the leadership and masses on their return to Moscow. Later Kamanin plays tennis with the crew. Kamanin believes that Malinovskiy has finally become more supportive of Soviet manned spaceflight, which can be seen as a reflection of the country's military potential. Unwavering support will be needed to fulfil the recently approved space plan, which foresees manned docking operations in orbit, a manned flyby of the moon, a manned lunar landing, and missions of 20 to 30 days in earth orbit.

  • Voskhod 1 crew in Moscow - . Nation: USSR. Related Persons: Komarov; Yegorov; Feoktistov; Brezhnev; Biryuzov. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. The crew arrives at Vnukovo Airfield at 12:30 aboard an Il-18. The crew walks up to the reviewing stand and Komarov makes the standard report to the Communist Party and Soviet Ministers. At 14:00 there is a meeting at Red Square, and at 17:00 an audience at the Kremlin. The next day will be the customary meeting with Korolev and the workers of OKB-1, and the day after, the press conference, and on 22 October the meeting with the staff at the Cosmonaut Training Centre. The celebrations provide the first opportunity for Brezhnev to present himself in public in the role previously held by Khrushchev. The celebrations are somewhat dampened by new that an Il-18 crashed near Belgrade, killing all 17 occupants of a military delegation, including Marshal Biryuzov. This was the same aircraft and same crew that had flown the cosmonauts from Kustanin to Tyuratam....

  • Cosmonaut meeting at OKB-1 - . Nation: USSR. Related Persons: Komarov; Yegorov; Feoktistov; Korolev; Keldysh; Tyulin; Mozzhorin. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. The traditional meeting with the crew is followed by a smaller group in Korolev's office. Numerous toasts are drunk to the crew, to future victories in space, and... "on to the moon". From 18:00 to 20:00 the cosmonauts are prepared by Keldysh, Tyulin, Pashkov, Skuridin, Mozzhorin, Rumyanets, and others in allowable answers for the next day's press conference. Kamanin wants the crew to be free to answer questions about the physical characteristics of the booster and spacecraft (thrust, weight, dimensions, and so on) but Keldysh and Tyulin prohibit it strongly.

1964 October 28 - .
  • Voskhod plans - . Nation: USSR. Related Persons: Komarov; Yegorov; Feoktistov. Program: Voskhod. Flight: Voskhod 1; Voskhod 2; Voskhod 3; Voskhod 4; Voskhod 5; Voskhod 6. Spacecraft: Voskhod; Berkut. The Voskhod 1 crew have completed their post-flight debriefings and final report. Plans for 1965 are laid out. The Vykhod spacewalk flight will be made in the first quarter of 1965. Of the five Voskhod spacecraft, that are to be completed in the first quarter of 1965, the following program is laid out: two will be devoted to flights of a single cosmonaut, without a spacesuit, on endurance missions of 12 to 15 days. Two will be used for scientific research missions. One will be used to repeat the spacewalk of the Vykhod mission.

1964 November 3 - .
  • Cosmonauts dispersed - . Nation: USSR. Related Persons: Komarov; Yegorov; Feoktistov; Gagarin; Nikolayev; Popovich; Tereshkova; Titov; Bykovsky; Biryuzov. Kamanin receives a phone call from Serbin in the Central Committee, demanding that all nine flown cosmonauts be present at the unveiling of a space obelisk in Moscow the next day, and be on the podium at Red Square on 7 November. This is impossible - the cosmonauts are dispersed on vacation, cure, or public relations missions. Gagarin, Nikolayev, Popovich, and Tereshkova are in Sochi, and after discussion, it seems they will be able to get back by the next day. But Titov and Bykovsky are in Odessa, and it will take them three days to get back. The VVS leadership is contacted to arrange special flights, otherwise all nine could only be gathered by 9-10 November.

    Kamanin receives the decree creating the new TsUKOS military organisation that will direct Soviet spaceflight. He is sure such a resolution would never have passed had Biryuzov not been killed in the plane crash. The VVS retains only its existing role of cosmonaut training.


1964 November 4 - .
  • Space obelisk unveiling - . Nation: USSR. Related Persons: Komarov; Yegorov; Feoktistov; Gagarin; Titov; Nikolayev; Popovich; Tereshkova; Bykovsky; Brezhnev. Gagarin, Titov, Nikolayev, Popovich, Tereshkova, and Bykovsky have all managed to make it to Moscow by plane, and they meet at TsPK at 13:00. Kamanin takes the unique opportunity of having them all together to discuss plans for their higher engineering education at the Zhukovskiy Academy, plans for construction of new quarters at the TsPK, and an overview of planned future missions based on recent resolutions. At 14:30 the group departs in four Volga automobiles for Moscow. The unveiling ceremony is at 16:00. Brezhnev, Kosygin, Mikoyan, and other bigwigs are there as well.

1964 November 6 - .
  • Well deserved rest - . Nation: USSR. Related Persons: Komarov; Yegorov; Feoktistov. Flight: Voskhod 1. Summary: The cosmonauts will go to a rest area on 8 November. Kamanin is going on leave from 9 November to 20 December. On this last day of work, several cosmonauts receive the Vietnamese Hero of Socialist Labour medal from Vietnamese premier Pham Van Dong..

1965 March 29 - .
  • Cosmonaut travel plans - . Nation: USSR. Related Persons: Tereshkova; Nikolayev; Yegorov; Belyayev; Leonov; Gagarin. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. Tereshkova and Nikolayev are to travel to Algeria on 1 April, and Hungary on 2 April. Yegorov is going to Berlin to deliver a medical lecture. There is an avalanche of fan mail for Belyayev and Leonov. Kamanin believes that Leonov is moving into the pantheon with Gagarin and Tereshkova of top space heroes.

1965 September 23 - .
  • Voskhod 3 plans - . Nation: USSR. Related Persons: Korolev; Yegorov; Anokhin. Program: Voskhod. Flight: Voskhod 3; Voskhod 4; Gemini 7. Spacecraft: Voskhod. Korolev is charging ahead with the plan to fly Voskhod 3 for 20 days. Kamanin is doubtful - the life support system is rated for only 12-15 days, and testing to certify it for 25 days cannot be done in time. Korolev is also planning for a 15 November launch (to fly before Gemini 7). Kamanin believes instead a series of three flights should be flown - first to 12-15 days, then to 20 days, then to 25 days. It is essential the military experiments are flown on these flights. Yegorov and Anokhin have been sent to negotiate a protocol to be signed by Kamanin that he will prepare a crew consisting of a spacecraft commander and scientist-astronaut for a 20 day flight in time to support a 15 November launch. Kamanin refuses to sign the document - it is absurd and impossible.

1966 November 28 - .
  • Cosmos 133 - . Nation: USSR. Related Persons: Mishin; Rudenko; Kerimov; Gagarin; Nikolayev; Belyayev; Yegorov. Program: Soyuz. Flight: Soyuz 1; Soyuz 2A. Spacecraft: Soyuz 7K-OK. Four years behind Korolev's original promised schedule, the countdown is underway for the first Soyuz spacecraft. A new closed circuit television system allows the rocket to be observed from several angles during the final minutes. Mishin, as per tradition, personally stays with the rocket until the last moment. Rudenko, Kerimov, and Kamanin observe the launch from the bunker, while Gagarin, Nikolayev, Belyayev and Yegorov observe from the observation post. The launch is perfect, within 0.2 seconds of the 16:00 launch time. The separation of the first stage strap-ons can be seen with the naked eye in the clear sky. The spacecraft is given the cover designation Cosmos 133 after launch. By 22:00 the spacecraft is in deep trouble. For unknown reasons the spacecraft consumed its entire load of propellant for the DPO approach and orientation thrusters within a 15-minute period, leaving the spacecraft in a 2 rpm spin. At the insertion orbital perigee of 179 kilometres, the spacecraft will have a life of only 39 orbits. It is decided to attempt to stop the spin on the 13th orbit using other thrusters and the ion flow sensors to determine attitude. Then the re-entry sequence will be commanded on the 16th orbit, with the spacecraft to use solar sensors to orient itself for retrofire on the 17th orbit.
