Russian Venus probe. 2 launches, 1969.01.05 (Venera 6) to 1969.01.10 (Venera 6). Spacecraft was very similar to Venera 4 / 1V (V-67) although the descent module was of a stronger design.

When the atmosphere of Venus was approached, a capsule weighing 405 kg and containing scientific instruments was jettisoned from the main spacecraft. During descent towards the surface of Venus, a parachute opened to slow the rate of descent. For 53 min on May 16, 1969, while the capsule was suspended from the parachute, data from the Venusian atmosphere were returned. The spacecraft also carried a medallion bearing the coat of arms of the U.S.S.R. and a bas-relief of V.I. Lenin to the night side of Venus.

Gross mass: 1,128 kg (2,486 lb).
First Launch: 1969.01.05.
Last Launch: 1969.01.10.
Number: 2 .

  • 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...

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.

Venera 2V (V-69) Chronology


1969 January 5 - . 06:28 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC1. Launch Pad: LC1 or LC31. LV Family: R-7. Launch Vehicle: Molniya 8K78M.
  • Venera 5 - . Payload: 2V (V-69) s/n 330. Mass: 1,128 kg (2,486 lb). Nation: USSR. Related Persons: Babakin. Agency: MOM. Program: Venera. Class: Venus. Type: Venus probe. Spacecraft: Venera 2V (V-69). Decay Date: 1969-05-16 . USAF Sat Cat: 3642 . COSPAR: 1969-001A. Venera 5 is launched at 9:26 Moscow time from LC-31 in -23 deg C temperatures. All proceeds according to plan. Afterwards Kamanin meets Babakin. Venera 6 is planned for launch in 10 January. He also plans two moon landings in 1969 and two in 1970 of soil sample return spacecraft. Kamanin does not believe America can achieve a manned moon landing in 1969, and therefore that Babakin has a very good chance of stealing their thunder.

    Meanwhile Venera 5 was launched from its parking orbit towards Venus to obtain atmospheric data. The spacecraft was very similar to Venera 4 although it was of a stronger design. When the atmosphere of Venus was approached, a capsule weighing 405 kg and containing scientific instruments was jettisoned from the main spacecraft. During satellite descent towards the surface of Venus, a parachute opened to slow the rate of descent. For 53 min on May 16, 1969, while the capsule was suspended from the parachute, data from the Venusian atmosphere were returned. The spacecraft also carried a medallion bearing the coat of arms of the U.S.S.R. and a bas-relief of V.I. Lenin to the night side of Venus.
