The American space probe „ISEE-3“(International Sun/Earth Explorer) later renamed as “ICE” (International Cometary Explorer) was sent into heliocentric orbit in 1978. The mission of the space probe was to provide new data on the sun, earth, and comets. ICE was a versatile forerunner. This is the first probe to provide information on the solar winds, as well as on the composition of comets: these consist mainly of ice, gases, and organic molecules. It also supported other probes, such as the sun probe Ulysses, in their missions. Although ICE was officially abandoned in 1997, it is still floating around in space.
