International Cometary Explorer

The International Cometary Explorer (ICE) spacecraft was originally known as International Sun/Earth Explorer 3 (ISEE-3) satellite, launched August 12, 1978. It was part of the ISEE (International Sun-Earth Explorer) international cooperative program between NASA and ESRO/ESA to study the interaction between the Earth's magnetic field and the solar wind. The program used three spacecraft, a mother/daughter pair (ISEE 1 and ISEE 2) and a heliocentric spacecraft (ISEE 3, later renamed ICE).

ISEE 3 was the first spacecraft to be placed in a halo orbit at one of Earth-Sun Lagrangian points (L1). It was later (as ICE) sent to visit Comet Giacobini-Zinner and became the first spacecraft to do so by flying through a comet's tail passing the nucleus at a distance of approximately 7800 km. ICE was not equipped with cameras.

Famous quotes containing the word explorer:

    Treading the soil of the moon, palpating its pebbles, tasting the panic and splendor of the event, feeling in the pit of one’s stomach the separation from terra ... these form the most romantic sensation an explorer has ever known ... this is the only thing I can say about the matter. The utilitarian results do not interest me.
    Vladimir Nabokov (1899–1977)
