Yazdovskiy Chronology

1961 March 2 - .
  • Vostok launch preparations - . Nation: USSR. Related Persons: Korolev; Yazdovskiy; Gallay; Feoktistov; Alekseyev, Semyon; Keldysh; Bushuyev; Voskresenskiy. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok. Korolev, Yazdovskiy, Gallay, Feoktistov, Makarov, and Alekseyev spend over three hours editing the 'Instructions to Cosmonauts'. This is the first flight manual in the world for a piloted spacecraft, including instructions for all phases of flight and emergency situations. Korolev, Keldysh, Bushuyev, and Voskresenskiy want the instructions to be simply 'put on suit, check communications, observe functioning of the spacecraft'. Korolev is motivated by his belief that on this single-orbit flight everything should occur automatically. Kamanin, Yazdovskiy, Gallay, and Smirnov are categorically against such a passive role for the cosmonaut. They argue that the cosmonauts know the equipment and must be capable of manually flying the spacecraft after releasing the electronic logical lock. They need to observe the instruments, report on their status by radio, and make journal entries. The emotions of the cosmonaut during high-G's and zero-G must be understood in order to fully prepare the cosmonauts that will follow. After long debate, Korolev and Keldysh give in. The agreed first edition of the flight manual is signed by Korolev and Kamanin. The next Vostok 3KA launch is set for 9 March.

  • Vostok flight preparations - . Nation: USSR. Related Persons: Korolev; Alekseyev, Semyon; Yazdovskiy. Program: Vostok. Flight: Vostok 1. Korolev, Alekseyev, Yazdovskiy, and other engineers lay out the plan for the preparation of the cosmonaut on launch day. The cosmonaut will be put in Nedelin's cottage at Baikonur Area 2 the night before the launch, be awakened five hours before launch, and undergo a physical examination. Kamanin and Korolev will be in the bunker at the launch pad for at least the next two launches. After the launch, Kamanin is to fly to the recovery zone to be present for the landing of the spacecraft.

  • Kuibyshev - . Nation: USSR. Related Persons: Gagarin; Nelyubov; Popovich; Titov; Bykovsky; Nikolayev; Yazdovskiy; Karpov. Program: Vostok. Flight: Vostok 1. The VVS contingent departs for Tyuratam in three Il-14's. The two with cosmonauts aboard stop at Kuibyshev to give the pilots a look at the recovery zone. Aboard the first aircraft are Kamanin, Gagarin, Nelyubov, and Popovich. Aboard the other are Titov, Bykovsky, and Nikolayev. At the VVS Sanatorium at Privolzhskiy on the Volga the cosmonauts relax, and play ping-pong, chess, and billiards. The cosmonauts, Kamanin, Yazdovskiy, and Karpov sleep together in a single large room. Kamanin finds it a lively group; only Gagarin is pale and quieter than the others. On 7 March his wife had their second daughter and only yesterday he brought them back from the hospital. It was tough on him to then have to leave them on his dangerous secret mission - to be the first man into space.

  • Vostok launch delay - . Nation: USSR. Related Persons: Gusev; Feoktistov; Yazdovskiy; Karpov; Gagarin; Nelyubov; Titov. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok. The launch has been delayed to 24-25 March due to problems with L I Gusev's radio system aboard the spacecraft. A meeting of the cosmonauts at 10:00 reviews landing contingency plans that will bring the capsule down on the territory of the USSR. The best chances for such a landing are on orbits 1, 2, and 16, but it is also possible on orbits 4, 5, 6, and 7. A map will be aboard the capsule to show where and when to ignite the TDU retrorocket for each landing opportunity. Feoktistov was a great help in developing this visual aid. For about an hour Kamanin, Korolev, Yazdovskiy, Karpov, and Azbiyevich discuss long-range plans. Korolev is interested in the VVS position that they should be responsible for all military space activities. The reconnaissance satellite version of Vostok is discussed. Korolev says he plans to send a cosmonaut to the moon by 1965.

    Afterwards the cosmonauts develop the radio communications plan for the flight. During the 710-second ascent to orbit, and after landing, they are to use the UHF radio. The HF and UHF radios can be used from orbit, but only over the USSR. Plans for filming the cosmonaut in flight are also discussed.

  • Vostok 1 State Commission - . Nation: USSR. Related Persons: Moskalenko; Yazdovskiy; Titov; Gagarin; Korolev; Keldysh. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok. Rudnev chairs the meeting, in which Kamanin recommends that Gagarin pilot the first manned spaceflight, with Titov as backup. A discussion follows on whether to have a representative from the FAI at the launch in order to obtain registration of the world record. Marshal Moskalenko and Keldysh are opposed - they don't want anyone from outside at the secret cosmodrome. It is decided to enclose the code to unlock the controls of the spacecraft in a special packet. Gagarin will have to break it open in order to get the code that will allow him to override the automatic system and orient the spacecraft manually for re-entry. An emergency ejection during ascent to orbit is discussed. It is decided that only Korolev or Kamanin will be allowed to manually command an ejection in the first 40 seconds of flight. After that, the process will be automatic. There is embarrassment when Moskalenko confronts Yazdovskiy: 'so why are you here, when you're a veterinarian and only handle dogs?' Kamanin has to explain that Yazdovskiy is actually a medical doctor. After the meeting, Kamanin reviews Titov's training in the spacecraft, which has gone well.

  • Vostok 1 countdown - . Nation: USSR. Related Persons: Gagarin; Titov; Korolev; Yazdovskiy; Feoktistov. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok. The booster is rolled out to the pad at 05:00. At 10:00 the cosmonauts meet with Feoktistov for a last review of the flight plan. Launch is set of 09:07 the next day, followed by shutdown and jettison of the lateral boosters of the first stage at 09:09, and orbital insertion at 09:18. The spacecraft will orient itself toward the sun for retrofire at 09:50. At 10:15 the first command sequence will be uploaded to the spacecraft, followed by the second at 10:18 and the third at 10:25. Retrofire of the TDU engine will commence at 10:25:47. The service module will separate from the capsule at 10:36 as the capsule begins re-entry. The capsule's parachute will deploy at 10:43:43 and at 10:44:12 the cosmonaut's ejection seat will fire. While the cosmonauts go through this, the booster has been brought upright on the pad, the service towers raised, and all umbilical connections made. Korolev, Yazdovskiy, and the others make a final inspection at the pad prior to the commencement of the countdown. At 13:00 Gagarin meets a group of soldiers, NCO's, and officers. After this Kamanin and the cosmonauts go to the cottage formerly occupied by Marshal Nedelin, where they will spend the last night before launch. They eat 'space food' out of 160 g toothpaste-type tubes for lunch - two servings of meat puree and one of chocolate sauce. Gagarin's blood pressure is measured as 115/60, pulse 64, body temperature 36.8 deg C. He then subjects to placement of the biosensors he will wear during the flight, and baseline measurements are taken for an hour and twenty minutes. He is very calm through all this. At 21:30 Korolev comes to the cottage, says good night to the cosmonauts, then goes back out to check on launch preparations. Gagarin and Titov go to bed after this. Kamanin stays up a while in the next room, listening to them talk to one another in the dark.

  • Gagarin returns to Moscow - . Nation: USSR. Related Persons: Gagarin; Agaltsov; Yazdovskiy; Khrushchev. Program: Vostok. Flight: Vostok 1. Everyone is up at the dacha on the Volga at 06:00 and are ready to leave shortly thereafter. Now the weather in Moscow is expected to be fine. At 10:40 an Il-18 takes off for Moscow with Gagarin's party. This consists of Gagarin, Agaltsov, Rytov, Yazdovskiy, several correspondents, and some film operators. 50 km from Moscow seven fighters intercept the transport and form up as an escort, two off each wing, and three trailing. Gagarin calls them on the radio 'Brother fighter pilots - I send you greetings - Yuri Gagarin!' The aircraft formation flies down Lenin Prospekt, Red Square, and then up Gorkiy Street to Vnukovo. There are masses of people everywhere below. At exactly 15:00 the aircraft shuts down its engines 100 m from the reviewing stands. Yuri exits the aircraft and steps into history....

  • Vostok 2 discussions - . Nation: USSR. Related Persons: Yazdovskiy; Bushuyev; Feoktistov; Korolev. Program: Vostok. Flight: Vostok 2. Spacecraft: Sever; Vostok. Kamanin, Yazdovskiy, Bushuyev, and Feoktistov fly to Sochi. Korolev arrives on the next flight, and discussions begin on plans for the second Soviet manned spaceflight. Korolev wants a one-day/16-orbit flight, but Kamanin thinks this is too daring and wants a 3 to 4 orbit flight. Korolev rejects this, saying recovery on orbits 2 to 7 is not possible since the solar orientation sensor would not function (retrofire would have to take place in the earth's shadow). But Kamanin believes one day is too big a leap since the effects of sustained zero-G are not known. He finally agrees to a one-day flight, but with the proviso that a manually-oriented retrofire can be an option on orbits 2 to 7 if the cosmonaut is feeling unwell. Korolev reports that the new Sever spacecraft should be ready for flight by the third quarter of 1962. OKB-1 is working hard on the finding solutions to the problems of manoeuvring, rendezvous, and docking in orbit. Kamanin tells Korolev that it would be difficult to recruit and train three-man crews in time to support such an aggressive schedule.

1962 February 13 - .
  • Sever trial - . Nation: USSR. Related Persons: Voronin; Yazdovskiy; Vershinin; Bushuyev. Spacecraft: Sever. Summary: Vershinin, Bushuev and others are at OKB-124 for Voronin's Sever experiment. It was a bit mistake not to include IAKM in the 15-day experiment. This is Yazdovskiy's doing. He wanted to get a second source due to problems with IAKM's equipment.

1963 June 24 - .
  • Controversy over Tereshkova's performance - . Nation: USSR. Related Persons: Tereshkova; Korolev; Bykovsky; Keldysh; Tyulin; Yazdovskiy. Flight: Vostok 6; Vostok 5. The cosmonauts are prepared by Keldysh, Tyulin, and Korolev for their first big press conference. Yazdovskiy has inserted a paragraph in the official press release about Tereshkova's poor emotional state while in space. He claims she experienced overwhelming emotions, tiredness, and a sharply reduced ability to work and complete all of her assigned tasks. Kamanin takes him aside and asks him not to exaggerate her difficulties during the flight. She only had tasks assigned for the first day. When the flight was extended for a second, and then a third day, there was essentially nothing for her to do. The ground command did nothing to support her during those additional days. She certainly was never tired, never objected, but rather did all she could to complete fully the flight program.

1963 July 2 - .
  • Yazdovskiy presses complaints about Tereshkova's performance - . Nation: USSR. Related Persons: Tereshkova; Yazdovskiy. Flight: Vostok 6. Doctor Yazdovskiy is insisting that Tereshkova is not being truthful about her flight experience. She handed out rations to on-lookers at the landing site in order to cover up the fact she did not eat enough during the flight. Kamanin considers the accusation a stupidity and indicative of the constant war going on between the flight surgeons and the cosmonauts. Tereshkova powerfully denies the accusation and defends herself well.

1964 May 18 - .
  • OKB-1 Voskhod candidates - . Nation: USSR. Related Persons: Volkov; Grechko; Zaitsev; Kubasov; Makarov; Feoktistov; Yazdovskiy. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. Summary: 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)..
