  • Zenit project review - . Nation: Russia. Related Persons: Alekseyev, Semyon, Ustinov, Voronin. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok, Zenit-2 satellite, Zenit-4.

    Ustinov heads a review of the reconnaissance satellite program, at that time still referred to as the Vostok-2 and Vostok-4 spacecraft. Thirty staff are working on it full time at OKB-1, but Korolev says that due to delays in the photographic, television, and radar equipment for the spacecraft the first launch will be delayed two to three months. But he points out that since Vostok-1 has already proven the recovery systems, the first Vostok-2 should still be ready for launch in June-July 1961. Ustinov notes that the Ministry of Defence has had little input or understanding of the specification for the spacecraft. The launch of the first Vostok-3 is delayed to March due to the need to fully test all systems. The life support system (Vornonin) and the ejection seat (Alekseyev) are the pacing items. The next meeting is set for 27 February. Kustanin testifies as to the readiness of the spacecraft and the cosmonauts.

  • Vostok rollout - . Nation: Russia. Related Persons: Alekseyev, Semyon, Gagarin, Rudnev, Titov, Ustinov, Voronin. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok.

    At 08:54 a meeting is held, where it is decided the bad performance of Voronin and Alekseyev in completing their capsule subsystems will be reported to Ustinov and Rudnev. At 13:00 the booster is rolled out to the pad. At 18:00 Gagarin and Titov donn their space suits and practice riding the elevator up to the spacecraft, and entering the hatch. This is to give them a practical feel for the time it will actually take them to get aboard and complete checkout of the spacecraft and suit.

  • Vostok cleared for manned flight - . Nation: Russia. Related Persons: Dementiev, Korolev, Kozlov, Moskalenko, Ustinov, Voronin. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok.

    The capsule was recovered 45 km southeast of Votinsk. The mannequin was ejected successfully from the aircraft, the dog Zvezdochka was fine, and was displayed to journalists all day. Therefore all is ready for a manned flight. The cosmonauts agree: 'Everything is finished, we can fly'. All is ready for a one-orbit flight with recovery in the USSR, but Kamanin still worries about the lack of any realistic plan in emergency situations. The environmental control system has still not completed endurance tests, and won't be able to keep the cosmonaut alive for the ten to twelve days it would take the spacecraft to decay from orbit if the retrorocket fails. Trials with the hot mock-up of the ECS in the capsule have still not been successful. Furthermore, a recovery at sea is not practical.

    The pace quickens leading to the first human spaceflight. Kamanin coordinates matters with Korolev and Voronin, and then discusses the ECS problems and cosmonaut landing issues with Dementiev. Plans are made for a meeting with Ustinov and Kozlov. In the evening a meeting of the General Staff is held. Decisions made: 1) Announce the name of the cosmonaut as soon as he is in orbit; 2) improve VVS support (aircraft, helicopters) needed to pick up the cosmonaut immediately after landing; 3) issue a formal letter to Moskalenko on rules for filming of the cosmonaut at the launch site; 4) organise an examination of the 11 cosmonauts not in the group of six now being prepared for flights.

  • Vostok problems review - . Nation: Russia. Related Persons: Dementiev, Keldysh, Korolev, Voronin. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok.

    The meeting is held at G T Voronin's OKB-124 at the 'Daks' factory. All of the program bigwigs are there (Korolev, Keldysh, etc). The big issue is the problem with the oxygen regenerator. On the 10 day trial 4 litres of lithium chloride were consumed, but the test was unsuccessful. A new solution of chlorine-lithium is proposed. But this is dangerous - the doctors are worried that if it gets into the cosmonauts body, it will poison him. A sharp discussion ensues, but the final decision is to try a five day trial with lithium chloride. At 12:00 the commission proceeds to Dementiev's GKAT. The tests of the Vostok recovery system are reviewed. There were to have been two to four ejection seat tests from Il-28 bombers, tests, plus tests at sea at Fedosiya of the NAZ ejection seat and the characteristics of the parachute underwater. The discussion turns again to the five-day ECS cabin test. It is decided to keep the faulty gas analyser, but not to connect it to the telemetry - the readings will be read with a television camera instead. There is a clear political aspect in the argument between the VVS design bureau and the institute over the performance of the ECS system. Lieutenant-General Kolkov orders yet another examination of the cosmonauts.

  • Vostok preparations - . Nation: Russia. Related Persons: Grechko, Andrei, Korolev, Malinovskiy, Vershinin, Voronin, Zakharov. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok.

    The VVS leadership has been diverted for the last three days in meetings of the General Staff of the Warsaw Pact. At 09:00 Kamanin takes a break to prepare two letters. One goes to the Ministry of Defence, certifying readiness for the launch of Vostok 1 on 10-20 April; the other goes to Zakharov on the General Staff, turning over all in-flight photographs to the VVS. Vershsinin pages through Kamanin's photo album of earth photographs taken during the unmanned Vostok test flights. They show the precise orbital orientation of the spacecraft. He says he will show these to Grechko and Malinovskiy, trying to convince them of the usefulness of manned spaceflight. Kamain calls Korolev and advises him that Voronin is ready. Korolev says that he plans to put wood wool into the cabin to absorb any excess lithium chloride.

  • Vostok trials - . Nation: Russia. Related Persons: Voronin. Program: Vostok. Flight: Vostok 1. Spacecraft: Vostok.

    Trials of the NAZ ejection seat at sea with the underwater drag chute trials were unsuccessful. The NAZ is simply not seaworthy. The antenna remained submerged in all tests, making communications impossible. The five-day test of the ECS was also unsuccessful. The lithium chloride was used up at the end of four days. Kamanin believes that Voronin is a poor manager, and that a completely new solution to the Vostok life support system will be needed after the first flight.

  • Sever spacecraft trials - . Nation: Russia. Related Persons: Voronin. Spacecraft Bus: Soyuz. Spacecraft: Sever. Two officers start a 15 day test aboard a mock-up of the Sever spacecraft, but without the participation of the IAKM. The whole thing was planned by Voronin's OKB in GKNII..

1962 February 13 - .
  • Sever trial - . Nation: Russia. Related Persons: Bushuyev, Vershinin, Voronin, Yazdovskiy. Spacecraft Bus: Soyuz. Spacecraft: Sever. 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.

  • Conference on space cabin ecology. - . Nation: Russia. Related Persons: Keldysh, Korolev, Voronin. Spacecraft Bus: TMK. Spacecraft: TMK-1.

    Keldysh, Korolev, Voronin, and Kamanin attend a conference on space cabin ecology. Presentations are made by IAKM, OKB-124, the Biology Institute, and the Physiology Institute. In two to three years the USSR expects to orbit spacecraft of 78 to 80 tonnes, which will be assembled in earth orbit to produce larger spacecraft. These will not only fly around the moon, but also be used to fly to Venus, Mars, and other planets. Although it will take years, many technical problems have to be solved before such a spacecraft can be built. How to shield the crew from radiation? How best to regenerate the air? How to recycle the water? Can the crew survive for long flights in zero-G, or must some form of artificial gravity be provided? If so, what is the best method? How can the psychological health of the crew best be maintained on long flights?

    It is reported that a lot of test stand work has been completed and is underway on closed ecological systems for recycling the air and water. One kilogram of chlorella algae can produce 27 kg of oxygen per day. Since each man will require 25 kg of oxygen per day, 2 kg of chlorella per crew member will be adequate. Therefore the problem of recycling the cabin atmosphere is considered already solved.

    Food requirements per crew member are 2.5 to 3.0 kg/day, or about one tonne per year. It is expected that in two to three years development will be complete of a system that will recycle 80% of the food. A 150 kg device will produce 400 to 600 g of food per day, or 100 to 200 kg per year.

  • Landing of Voskhod 2 - . Return Crew: Belyayev, Leonov. Nation: Russia. Related Persons: Belyayev, Korolev, Leonov, Voronin. Program: Voskhod. Flight: Voskhod 2. Spacecraft Bus: Vostok. Spacecraft: Voskhod.

    On re-entry the primary automatic retrorocket system failed. A manually controlled retrofire was accomplished one orbit later (evidently using the primary engine, not the backup solid rocket retropack on the nose of spacecraft). The service module failed to separate completely, leading to wild gyrations of the joined reentry sphere - service module before connecting wires burned through. Vostok 2 finally landed near Perm in the Ural mountains in heavy forest at 59:34 N 55:28 E on March 19, 1965 9:02 GMT. The crew spent two nights in deep woods, surrounded by wolves. Recovery crews had to chop down trees to clear landing zones for helicopter recovery of the crew, who had to ski to the clearing from the spacecraft. Only some days later could the capsule itself be removed. Additional Details: here....

  • Voskhod ECS - . Nation: Russia. Related Persons: Voronin. Program: Voskhod. Flight: Voskhod 3, Voskhod 4.

    Kamanin discusses the environmental control system for the 20-day Voskhod fight. Chief Constructor Voronin tells him that to develop such a system to support two crew for 20 days is fully possible; but it will take months of development and testing to certify it for flight. There is no way it will be ready until the first quarter of 1966.

  • New cosmonauts - . Nation: Russia. Related Persons: Babiychuk, Korolev, Voronin. Program: Voskhod, Soyuz, Lunar L1, . Flight: Voskhod 3. Spacecraft Bus: Vostok. Spacecraft: Voskhod.

    Kamanin meets the 22 new cosmonaut candidates. Some higher officers have questioned the need for so many cosmonauts in training - 32 are already available. But Kamanin sees plans for 40 to 50 manned spaceflights over the next 3 to 4 years. He expects to see some of these cosmonauts walking on the moon, and others on expeditions to other planets. Later Kamanin has to call Korolev after a dispute breaks out between Voronin and Babiychuk and Frolov. Voskhod 3 will not be cleared for flight because the trials of the long-duration environmental control system will not be undertaken at designer Voronin's institute. Furthermore it is still the position of the military that Voskhod 4 should conduct some military experiments.

  • Kamanin and Korolev clash - . Nation: Russia. Related Persons: Glushko, Gorbatko, Katys, Korolev, Kosberg, Pilyugin, Volynov, Voronin. Program: Voskhod. Flight: Voskhod 3. Spacecraft Bus: Vostok. Spacecraft: Voskhod.

    The two have a difficult discussion over crewing for Voskhod 3. Korolev has found that Katys has been taken out of training for the mission. He does not agree with Kamanin's all-military pilot crew of Volynov and Gorbatko. Kamanin is tired of Korolev's caprices and his endless fighting with Glushko, Pilyugin, Voronin, Kosberg, and other chief designers. Korolev has had it with the military excluding civilians and civilian objectives from manned space.

  • Lunar expedition - . Nation: Russia. Related Persons: Gagarin, Komarov, Nikolayev, Voronin. Program: Voskhod. Flight: Voskhod 3. Spacecraft Bus: Vostok. Spacecraft: Voskhod.

    Kamanin spent six hours the previous Saturday reviewing the development plan over the next 24-30 months of the Soviet manned lunar landing with Gagarin, Nikolayev, and Komarov. Today is the third day of the duration test of the Voskhod-3 ECS at IMBP. It is showing unstable temperature control; the cabin is vacillating between 25 and 15 deg C. After review by the engineers and Voronin, it is decided to continue with the run.

  • Voskhod ECS Tests - . Nation: Russia. Related Persons: Voronin. Program: Voskhod. Flight: Voskhod 3. Spacecraft Bus: Vostok. Spacecraft: Voskhod. The tests at IMBP are going very poorly. The temperature in the cabin has gone as low as 12 deg C. In factory trials Voronin was able to control this by closing the 'window blind' radiators..

  • Voskhod 3 ECS - . Nation: Russia. Related Persons: Voronin. Program: Voskhod. Flight: Voskhod 3. Spacecraft Bus: Vostok. Spacecraft: Voskhod.

    Today the trials at Voronin's OKB-124 had to be halted after a 16 day run, when the cabin oxygen level went out of limits. It seems the cosmonauts could control it in flight by closely monitoring the cabin atmosphere composition and changing cartridges as necessary (typically after 5.5 days), but this is not a reliable basis for a flight. For a 20 day flight, a 22-day endurance run on earth should be a minimum, but neither the IMBP or OKB-124 have been able to make the system run longer than 14-16 days before it breaks down. Later the State Commission meets. Cosmos 110 continues in normal flight, the dogs and other life forms are alive. The only minus is that data received is complete due to the failure of the antennae to deploy.

  • Voskhod 3 State Commission - . Nation: Russia. Related Persons: Shabarov, Tsybin, Voronin. Program: Voskhod. Flight: Voskhod 3. Spacecraft Bus: Vostok. 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.

  • VPK Meeting - L1 delays - . Nation: Russia. Related Persons: Chelomei, Mishin, Severin, Vershinin, Voronin. Program: Lunar L1. Flight: Soyuz 7K-L1 mission 1. Spacecraft Bus: Soyuz. 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.

  • ECS technology review. - . Nation: Russia. Related Persons: Gazenko, Keldysh, Severin, Voronin. Program: Salyut. Spacecraft: Aelita satellite, MKBS, Salyut 1.

    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.
