Reduction of Galileo and Ulysses dust data

Hamilton, D. P.; Grün, E.; Kissel, J. +4 more

The reduction procedures which are applied to raw data from the Galileo and Ulysses Dust Detectors are described in order to obtain physical parameters (mass and velocity) for the recorded dust impacts. Both detectors are impact ionization detectors which measure the charge released from an impact onto a solid target. From the rise times of the si…

Two years of Ulysses dust data

Hamilton, D. P.; Grün, E.; Kissel, J. +16 more

From October 18, 1990 to February 8, 1992 the Ulysses spacecraft traversed interplanetary space between the Earth and Jupiter; at Jupiter the spacecraft was deflected below the ecliptic onto a highly-inclined orbit ( i∼80°). Here, we report on dust impact data obtained from launch until the end of 1992, nearly a year after the Jupiter flyby. Durin…

Dust particles beyond the asteroid belt - a study based on recent results of the Ulysses dust experiment

Mann, Ingrid; Grün, Eberhard

Dust fluxes detected by the Ulysses dust experiment beyond the asteroid belt, their possible sources and the possibilities of comparing them to observations of dust in the Zodiacal light are discussed. The dust fluxes detected at solar distances about r < 2.5 AU are compatible with a population of interplanetary dust particles moving on low ecc…
