Giotto Extended Mission

The Giotto spacecraft was launched on 2 July 1985 to study comet 1P/Halley. The spacecraft carried instruments to image the nucleus, analyze components of the cometary coma, the cometary atmosphere and ionosphere, cometary dust particles, and plasma flows resulting from the interaction of cometary and solar wind. Giotto encountered comet 1P/Halley on 13 March 1986 and came within 596 km of the nucleus. Following the encounter Giotto was placed into a hibernation mode. The spacecraft was reactivated for an extended mission in 1992. Giotto encountered comet 26P/Grigg-Skjellerup on 10 July 1992 and came within a distance of approximately 200 km of the nucleus. Spacecraft operations were terminated on 23 July 1992.

The SBN is the lead PDS node for archiving Giotto data which are also available through the ESA Planetary Science Archive.
