  • R-7 The world's first ICBM became the most often used and most reliable launch vehicle in history. The original core+four strap-on booster missile had a small third stage added to produce the Vostok launch vehicle, with a payload of 5 metric tons. Addition of a larger third stage produced the Voskhod/Soyuz vehicle, with a payload over 6 metric tons. Using this with a fourth stage, the resulting Molniya booster placed communications satellites and early lunar and planetary probes in higher energy trajectories. By the year 2000 over 1,628 had been launched with an unmatched success rate of 97.5% for production models. Improved models providing commercial launch services for international customers entered service in the new millenium, and a new launch pad at Kourou was to be inaugurated in 2011. It appeared that the R-7 could easily still be in service 70 years after its first launch. More...

  • 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...

Associated Launch Sites
  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.

  • Plesetsk Plesetsk was the Soviet Union's northern cosmodrome, used for polar orbit launches of mainly military satellites, and was at one time the busiest launch centre in the world. The collapse of the Soviet Union put the main launch site of Baikonur in Kazakh territory. It now seems that once the Proton rocket is retired, Baikonur will be abandoned and Plesetsk will be Russia's primary launch centre. Upgrades to existing launch facilities will allow advanced versions of the Soyuz rocket and the new Angara launch vehicle to be launched from Plesetsk. Plesetsk's major drawback was the lower net payload in geosynchronous orbit from a northern latitude launch site. However Russia is planning to remove the disadvantage by looping geosynchronous satellites around the moon, using lunar gravity to make the necessary orbital plane change. More...
  • Plesetsk LC41/1 R-7 launch complex. Code named 'Lesobaza', this was the first complex completed at Plesetsk, being declared ready for military service with the R-7A ICBM in November 1959.

  • Korolev requests new Vostoks - . Nation: USSR. Related Persons: Korolev. Program: Vostok. Spacecraft: Vostok; Vostok-Zh; Zenit-4. Korolev has issued a letter requested eight new Vostok 3A spacecraft to be built in 1962-1963. He recommends that they should be finished as the 1100 to 1300 kg heavier 'Vostok-2', to be boosted by the 11A57 rocket, developed originally for the Zenit-4 spy satellite. These Vostok-2's will be used for docking experiments, to form EO Experimental Orbital stations, and to develop spacecraft systems for flight to the moon. The VVS fully supports these plans. One of the docking spacecraft will be piloted, the other unpiloted.

1964 September 9 - . LV Family: R-7. Launch Vehicle: Voskhod 11A57.
  • Voskhod preparations - . Nation: USSR. Related Persons: Krylov; Rudenko; Korolev. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod; Zenit-4. Kamanin arrives at the cosmodrome, only to find the launch of the manned Voskhod delayed to October. The launch of a Zenit-4 spy satellite, that uses the same launch vehicle as planned for Voskhod, has aborted on the pad after the Block A strap-on failed to ignite. This is the first block A failure in over 100 R-7 launches. That evening Kamanin views a launch of an R-36 heavy ICBM. Marshall Krylov reveals it will have a range of 14,000 km with a CEP of under 1 km with a 40 megaton warhead - one missile is sufficient to wipe out a city like New York. Rudenko believes that the victor in any nuclear war will be the one who pushes the button first. Krylov disagrees, saying that if the Americans would launch an attack on Soviet missile forces, the Soviet Union would launch its missiles on a counter-strike before the American missiles arrive - total and senseless destruction. Rudenko believes that Rudenko is more correct, since in the real-world responses will not conform to theoretical possibilities of instant reaction.

    Later the state commission meets to consider the launch of the first Voskhod. The unpleasantness at the landing trials in the Crimea reveal only the inadequacy of the design of the test capsules, and do not reflect the flight system, says Korolev. He certifies the reliability of the Voskhod for flight. The commission decides to set the launch of the next Zenit-4 reconnaissance satellite for 14 September; that of the Voskhod with mannequins on 18-20 September; the definitive landing system trial at Fedosiya on 23 September; and if that is successful, launch of a manned Voskhod by the end of September.

Spacecraft: Zenit-4. Duration: 5.00 days. Decay Date: 1964-09-18 . USAF Sat Cat: 880 . COSPAR: 1964-055A. Apogee: 311 km (193 mi). Perigee: 203 km (126 mi). Inclination: 64.9000 deg. Period: 89.60 min. High resolution photo reconnaissance satellite; returned film capsule; also carried weather experiments. The Zenit-4 launches a day ahead of schedule. The booster rocket performs perfectly as Korolev and Kamanin watch from the veranda of the IP-1 tracking station. This confirms readiness of the same launch vehicle for the Voskhod launch.

Type: Manned spacecraft. Flight: Voskhod 1. Spacecraft: Voskhod. Duration: 1.01 days. Decay Date: 1964-10-07 . USAF Sat Cat: 891 . COSPAR: 1964-062A. Apogee: 383 km (237 mi). Perigee: 174 km (108 mi). Inclination: 64.6000 deg. Period: 90.10 min. Unmanned test of Voskhod spacecraft. At 07:00 the State Commission meets at Area 2. All Chief Designers, Commanders, and Section report that all is ready for flight. The commission gives the order to proceed with the launch. Weather at the pad is 7 balls, 8-10 m/s wind with gusts to 15 m/s, temperature 9 to 12 deg C. Weather in the recovery zones is reported as winds up to 15 m/s. Weather in the recovery zone is not clear, but that is not considered an impediment, and in fact Kamanin would like to see how the landing system functions in bad conditions. Kamanin visits the pad at T-30 seconds; at T-20 seconds, the veranda at IP-1 has over 50 viewers of the launch, including 15 cosmonaut candidates and the 7 Voskhod cosmonauts. Kamanin is relegated to the IP-1 veranda this time, with Rudenko, Kirillov, and Tyulin the bunker adjacent to the pad. Korolev stays with the booster until T-5 minutes, then enters the bunker. The booster ignites precisely at 10:00; the strap-ons burn out and are jettisoned at T+120 seconds; the core burns out and the final stage ignites at T+290 seconds; and at T+523 seconds spacecraft 3KV number 2 is placed in orbit as the final stage shuts down. The spacecraft separates and all systems look normal.

  • Cosmos 47 returns to earth. - . Nation: USSR. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. At 7 am the Cosmos 47 landing commission convenes. Kamanin has had only three hours sleep. The spacecraft is to conduct retrofire on its 17th orbit of the earth and land in Kustan, where winds are 15-17 m/s. The capsule made a good landing, with the parachute-rocket soft landing system working perfectly - the spacecraft had zero velocity on impact with the ground. The spacecraft penetrated 90 mm into the ground. The strong winds caught the parachute after landing and dragged it 160 m, but if a crew had been aboard they could have quickly commanded separation of the parachute. All systems of the booster and spacecraft worked perfectly, except that the third stage engines' thrust fell by 10% for three seconds, but the engine controller detected the shortfall and made up the velocity.

1964 October 8 - . LV Family: R-7. Launch Vehicle: Voskhod 11A57.
  • Cosmos 47 capsule returned to Baikonur. - . Nation: USSR. Related Persons: Kosberg. Program: Voskhod. Flight: Voskhod 1. Spacecraft: Voskhod. The capsule arrived aboard an An-12 at 11:30. All systems performed well. It is reported that one of Kosberg's third stage engines developed an out-of-control high frequency oscillation in a stand test, and exploded. The State Commission decides to delay the manned Voskhod launch 3 or 4 days while the safety of the engines on the booster are verified. A special commission is sent to Voronezh to assess the situation. Kosberg's engines have flown 60 times, and been tested on the stand 400 times, without this problem having occurred before. In the evening seven reporters arrive from the Soviet press and begin their work leading up to the manned launch.

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....

Period: 90.90 min. First spacewalk, with a two man crew of Colonel Pavel Belyayev and Lt. Colonel Aleksey Leonov. During Voskhod 2's second orbit, Leonov stepped from the vehicle and performed mankind's first "walk in space." After 10 min of extravehicular activity, he returned safely to the spacecraft through an inflatable airlock.

    This mission was originally named 'Vykhod ('Exit/Advance'). It almost ended in disaster when Leonov was unable to reenter the airlock due to stiffness of the inflated spacesuit. He had to bleed air from the suit in order to get into the airlock. After Leonov finally managed to get back into the spacecraft cabin, the primary hatch would not seal completely. The environmental control system compensated by flooding the cabin with oxygen, creating a serious fire hazard in a craft only qualified for sea level nitrogen-oxygen gas mixes (Cosmonaut Bondarenko had burned to death in a ground accident in such circumstances, preceding the Apollo 204 disaster by many years).
