Russian Venus probe. 2 launches, 1967.06.12 (Venera 4) to 1967.06.17 (Cosmos 167). Venus probe with the announced mission of direct atmospheric studies.

The descent vehicle carried two thermometers, a barometer, a radio altimeter, an atmospheric density gauge, 11 gas analyzers, and two radio transmitters operating in the DM waveband. The main bus, which carried the capsule to Venus, had a magnetometer, cosmic ray detectors, hydrogen and oxygen indicators, and charged particle traps. Signals were returned by the spacecraft, which braked and then deployed a parachute system after entering the Venusian atmosphere, until it reached an altitude of 24.96 km.

Gross mass: 1,105 kg (2,436 lb).
First Launch: 1967.06.12.
Last Launch: 1967.06.17.
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.

1967 June 12 - . 02:39 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC1. LV Family: R-7. Launch Vehicle: Molniya 8K78M.
  • Venera 4 - . Payload: 1V (V-67) s/n 310. Mass: 1,104 kg (2,433 lb). Nation: USSR. Agency: MOM. Program: Venera. Class: Venus. Type: Venus probe. Spacecraft: Venera 1V (V-67). Decay Date: 1967-10-18 . USAF Sat Cat: 2840 . COSPAR: 1967-058A. Venera 4 was successfully launched towards the planet Venus with the announced mission of direct atmospheric studies. On October 18, 1967, the descent vehicle entered the Venusian atmosphere. Signals were returned by the spacecraft, which deployed a parachute after braking to subsonic velocity in the Venusian atmosphere, until it reached an altitude of 24.96 km.

1967 June 17 - . 02:36 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC1. LV Family: R-7. Launch Vehicle: Molniya 8K78M. FAILURE: Stage 4's engine 11D33 failed to ignite because the turbopump had not been cooled before ignition.. Failed Stage: 3.
  • Cosmos 167 - . Payload: 1V (V-67) s/n 311. Mass: 1,106 kg (2,438 lb). Nation: USSR. Agency: MOM. Program: Venera. Class: Venus. Type: Venus probe. Spacecraft: Venera 1V (V-67). Decay Date: 1967-06-25 . USAF Sat Cat: 2852 . COSPAR: 1967-063A. Apogee: 264 km (164 mi). Perigee: 211 km (131 mi). Inclination: 51.8000 deg. Period: 89.20 min. Suggestions for the cause of the failure included incorrect soldering of wires in multiple pin plugs, wrong attachments of the plugs to the pyrotechnic connectors, or a mix-up of the pyrotechnic connectors during assembly.. Investigation of the upper atmosphere and outer space.
