Dust detectors in the past flew on the HEOS-2, "Helios", "Pioneer 10", "Pioneer 11", "Giotto", "Galileo" and "Cassini" space missions, on the Earth-orbiting LDEF, EURECA, and Gorid satellites, and some scientists have utilized the "Voyager 1" and "2" spacecraft as giant Langmuir probes to directly sample the cosmic dust. Presently dust detectors are flying on the "Ulysses", Proba, "Rosetta", "Stardust", and the "New Horizons" spacecraft. The collected dust at Earth or collected further in space and returned by sample-return space missions is then analyzed by dust scientists in their respective laboratories all over the world. One large storage facility for cosmic dust exists at the NASA Houston JSC.
