The Vega mission to Venus and to Comet Halley was
implemented by the USSR with international particiption.
Two spacecraft, Vega 1 and Vega 2, were launched on
December 15 and 21, 1984.  They encountered Venus
during June, 1985, where each deployed a descent module
and a set of balloon-borne atmospheric sensors.  The main
spacecraft encountered Comet Halley March 6 and 9, 1986.
Significant data were obtained during both the encounter and
cruise phases of the mission.

More details on the mission are available from the
NSSDC Master Catalog at

This directory contains magnetic field, plasma and
energetic particle data obtained from the cruise phase
