Manufacturer's Designation: 3V (V-72). Class: Planetary. Type: Venus. Nation: USSR. Manufacturer: Lavochkin.

Venus atmospheric probe; instrumentation included temperature, pressure, and light sensors as well as radio transmitters. Velocity at Venus was reduced from 41,696 km/hr to about 900 km/hr by aerobraking. The 2.5 meter diameter parachute opened at an altitude of 60 km, and a refrigeration system was used to cool the interior components. Transmitted data during the descent and continued to send back data after landing.


Specification

Total Mass: 1,180 kg.


Venera 3V (V-72) Chronology


27 March 1972 Venera 8 Program: Venera. Launch Site: Baikonur . Launch Vehicle: Molniya 8K78M. Mass: 1,180 kg.

Venus atmospheric probe. The spacecraft took 117 days to reach Venus, entering the atmosphere on 22 July 1972. Descent speed was reduced from 41,696 km/hr to about 900 km/hr by aerobraking. The 2.5 meter diameter parachute opened at an altitude of 60 km, and a refrigeration system was used to cool the interior components. Venera 8 transmitted data during the descent and continued to send back data for 50 minutes after landing. The probe confirmed the earlier data on the high Venus surface temperature and pressure returned by Venera 7, and also measured the light level as being suitable for surface photography, finding it to be similar to the amount of light on Earth on an overcast day.


31 March 1972 Cosmos 482 Program: Venera. Launch Site: Baikonur . Launch Vehicle: Molniya 8K78M. FAILURE: The escape stage Block L's engine cut off 125 seconds after ignition due to timer failure. Mass: 1,180 kg. Perigee: 204 km. Apogee: 9,806 km. Inclination: 52.0 deg.
