Talk:Halley's Comet

Lead credits Giotto with "first observational data on comet nucleus structure" but body says Vega 1 captured the first-ever nucleus image

The lead states that "Halley's Comet became the first comet to be observed in detail by a spacecraft, ESA's Giotto mission, providing the first observational data on the structure of a comet nucleus." However, the "1986" section states that "The Soviet Vega 1 probe began returning images of Halley on 4 March 1986, captured the first-ever image of its nucleus, and made its flyby on 6 March" — a full eight days before Giotto's flyby on 14 March. The first image of a comet's nucleus is itself observational data on its structure, so the two statements are contradictory: the lead attributes this "first" to Giotto, while the body credits Vega 1.
