Vega 1 and 2
Two identical Soviet spacecraft each carrying a Venus
lander and Halley's Comet flyby probe.
The spacecraft released balloons into the atmosphere of Venus and landers
onto the surface before flying on to a rendezvous with Halley in March 1986.
The twin Vegas passed 8,900 km and 8,000 km, respectively, from the comet's
nucleus, returning photographs and analyzing ejected gas and dust. Both
had a mass of about 4,000 kg and were launched by a Proton rocket.
