  • Soyuz The Russian Soyuz spacecraft has been the longest-lived, most adaptable, and most successful manned spacecraft design. In production for fifty years, more than 240 have been built and flown on a wide range of missions. The design will remain in use with the international space station well into the 21st century, providing the only manned access to the station after the retirement of the shuttle in 2011. More...

Associated Launch Vehicles
  • Soyuz Russian orbital launch vehicle. 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 2009. It appeared that the R-7 could easily still be in service 70 years after its first launch. More...
  • Molniya 8K78 Russian orbital launch vehicle. Four stage derivative of the R-7 ICBM developed on a crash-program basis in 1960 for Soviet lunar and planetary deep space probe missions. The third stage found later use in the Voskhod and Soyuz launchers. By the 1970's mature versions of the launch vehicle were used almost entirely for launch of Molniya communications satellites and Oko missile early warning spacecraft into elliptical, 12-hour earth orbits.

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.

Mars 2MV-1 Chronology


1962 August 25 - . 02:18 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC1. LV Family: R-7. Launch Vehicle: Molniya 8K78. LV Configuration: Molniya 8K78 T103-12. FAILURE: At T+60 min 50 sec one of the four solid motors of the escape stage's BOZ unit did not fire. The resulting asymmetric torque caused the stage to lose correct attitude and three seconds after ignition of the main engine S1.5400A1 it began to tumble.. Failed Stage: 3.
  • Sputnik 19 - . Payload: 2MV-1 s/n 1. Mass: 890 kg (1,960 lb). Nation: USSR. Related Persons: Kuznetsova; Ponomaryova; Solovyova; Tereshkova; Yerkina. Agency: RVSN. Program: Venera; Vostok. Class: Venus. Type: Venus probe. Spacecraft: Mars 2MV-1. Decay Date: 1962-08-28 . USAF Sat Cat: 371 . COSPAR: 1962-A-Pi-1. Apogee: 252 km (156 mi). Perigee: 173 km (107 mi). Inclination: 64.9000 deg. Period: 88.70 min. Attempt to launch a probe towards Mars. The launch went well, but the fourth stage motor burnt for only 45s of the planned 240s. The stage remained in Earth orbit. However Kamanin notes that it was good that the launch of the basic vehicle was a success - it gave the visiting female cosmonauts confidence in the rocket they will have to ride.

1962 September 1 - . 02:12 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC1. LV Family: R-7. Launch Vehicle: Molniya 8K78. LV Configuration: Molniya 8K78 T103-13. FAILURE: At T+ 61 min 30 sec the fuel valve did not open.; the ignition command was blocked from going to the main engine of Stage 4.. Failed Stage: 3.
  • Sputnik 20 - . Payload: 2MV-1 s/n 2. Mass: 6,500 kg (14,300 lb). Nation: USSR. Agency: RVSN. Program: Venera. Class: Venus. Type: Venus probe. Spacecraft: Mars 2MV-1. Decay Date: 1962-09-06 . USAF Sat Cat: 381 . COSPAR: 1962-A-Tau-1. Apogee: 246 km (152 mi). Perigee: 185 km (114 mi). Inclination: 64.7000 deg. Period: 88.80 min.
