Russian Venus probe. The Vega 5VK spacecraft was designed for a mission combining a flyby of the planet Venus followed by an encounter with Halley's Comet. Venus flyby, Comet Halley flyby satellite, Russia. Launched 1984.

AKA: 5VK. Status: Operational 1984. First Launch: 1984-12-15. Last Launch: 1984-12-21. Number: 2 . Gross mass: 4,000 kg (8,800 lb).

At Venus a lander with a small balloon would be dropped into the clouds.

Original plans called for two versions, 5VS and 5VP. The 5VP Venus orbiter would be a relay station for a big Soviet-French balloon, to be dropped into the Venusian atmosphere by the 5VP Halley's comet probe as it flew by Venus. In 1981, it was decided to cancel the 5VS orbiters and redesign the 5VP to expand the Halley research program (this may have been in response to the cancellation of the US Halley probe the same year).

On the resulting Vega 5VK spacecraft the big Soviet-French balloon was replaced by a smaller Soviet-built balloon and a Venera 4V-1 type lander (minus camera). The flyby bus was equipped with the same solar panels as the Venera 4V-2 and carried a scan platform with remote sensing instruments to study Halley as well as extra dust protection shields.

The Vega 5VK spacecraft were fitted with scientific apparatus and equipment built in the USSR, Austria, Bulgaria, Hungary, German Democratic Republic, Poland, France, Federal Republic of Germany and Czechoslovakia.
