Vega 1 launched
The unmanned Vega 1 space probe is launched by the Soviet Union on a dual mission to drop off a lander at Venus and then to intercept Halley’s Comet in 1986. Derived from the USSR’s earlier Venera Venus landers, Vega will test a refined landing system for landing on Venus by balloon, and will then join an international fleet of unmanned spacecraft attempting to take advantage of Halley’s visit to the inner solar system in late 1985 and early 1986.
Just days after its twin lifts off, the unmanned Vega 2 space probe is launched by the Soviet Union on a dual mission to drop off a lander at Venus and then to intercept Halley’s Comet in 1986. Derived from the USSR’s earlier Venera Venus landers, Vega 2 will test a refined landing system for landing on Venus by balloon, and will then join an international fleet of unmanned spacecraft attempting to take advantage of Halley’s visit to the inner solar system in late 1985 and early 1986.
The Soviet Union’s unmanned space probe Vega 1 makes its closest approach to the nucleus of Halley’s Comet, a little over 5,000 miles away (a closer flight path is taken by its twin, Vega 2). Information gathered in the earliest stages of the encounter is shared with the European Space Agency, whose Giotto unmanned probe will make a much closer examination of Halley. Vega 1 registers an immense number of impacts from dust particles, but sustains no serious damage in close proximity to the comet; after several days of observations, Vega 1 is allowed to fall into an orbit around the sun.
The Soviet Union’s unmanned space probe Vega 2 makes its closest approach to the nucleus of Halley’s Comet, within 5,000 miles of the comet’s icy core. Hundreds of photos are taken and transmitted back to Earth, along with analysis of the dust and gas surrounding the comet. Within a week, Vega 2’s mission is complete, and the probe is allowed to fall into an orbit around the sun as Halley continues to speed back toward the outer solar system.
