Giotto :ESA's first deep space mission, Giotto was designed to help solve the mysteries surrounding Comet Halley by passing as close as possible to the comet's nucleus, which it achieved on 13 March 1986. Giotto/HMC :Halley Multicolour Camera (HMC) on board Giotto. Designed to provide high-resolution images of the nucleus and the coma of Halley's comet in nine colors and two polarizations.id:Giotto/HMC.a |
