Giotto was an ESA mission to fly by Comet Halley. It was launched in 1985, flew by its target in 1986. It was still operational and was reused for another flyby, as the Giotto Extended Mission (GEM), flying by the comet Grigg-Skjellerup (26P/Grigg-Skjellerup) in 1992. The spacecraft was shut down the same year. Instruments:
