- The Ulysses dust experiment is intended to provide direct observations of dust
grains with masses between 10**-16 g and 10**-6 g in interplanetary space, to
investigate their physical and dynamical properties as functions of
heliocentric distance and ecliptic latitude. Of special interest is the
question of what portion is provided by comets, asteroids and interstellar
particles. The investigation is performed with an instrument that measures the
mass, speed, flight direction and electric charge of individual dust particles.
It is a multicoincidence detector with a mass sensitivity 10**6 times higher
than that of previous in situ experiments which measured dust in the outer
solar system. The instrument weighs 3.8 kg, consumes 2.2 W, and has a normal
data transmission rate of 8 bits/s in nominal spacecraft tracking mode. On 27th
October 1990 the instrument was switched on. The instrument was configured to
flight conditions and science data collection started immediately. In the
period to 13th January 1991 at least 44 dust impacts have been recorded. Flux
values are given covering the heliocentric distance range from 1.04 to 1.7 AU.
