From September 1991 to October 1992, the cosmic dust detector on the Ulysses spacecraft recorded 11 short bursts, or streams, of dust. These dust grains emanated from the jovian system, and their trajectories were strongly affected by solar wind magnetic field forces. Analyses of the on-board measurements of these fields, and of stream approach directions, show that stream-associated dust grain masses are of the order of 10−18 gram and dust grain velocities exceed 200 kilometers per second… 

Cosmic Dust: The Ulysses perspective

The Ulysses spacecraft, launched in October 1990, orbits the Sun on a polar trajectory. The spacecraft is equipped with a highly sensitive impact- ionization dust detector which can in situ measure

High-velocity streams of dust originating from Saturn

All bursts of dust impacts detected within 150 Saturn radii are characterized by impact directions markedly different from those measured between the bursts, and they clearly coincide with the spacecraft's traversals through streams of compressed solar wind.

Dust measurements in the Jovian magnetosphere

Dust measurements have been obtained with the dust detector onboard the Galileo spacecraft inside a distance of about 60RJ from Jupiter (Jupiter radius, RJ = 71,492 km) during two periods of about 8

Jovian dust streams: Probes of the Io plasma torus

Jupiter was discovered to be a source of high speed dust particles by the Ulysses spacecraft in 1992. These dust particles originate from the volcanic plumes on Io. They collect electrostatic charges

Detection of an impact-generated dust cloud around Ganymede

Dust pervades the Solar System, and is concentrated in the ring systems surrounding the giant planets and along the plane of the planetary orbits (the Zodiacal cloud). Individual dust grains are

Dust Plasma Interactions at Jupiter

This is a review of recent in situ and remote sensing observations, and theoretical advances of our understanding dust plasma interactions in Jupiter's magnetosphere. Dust grains exposed to plasmas

Observations of Electromagnetically Coupled Dust in the Jovian Magnetosphere

We report on dust measurements obtained during the seventh orbit of the Galileo spacecraft about Jupiter. The most prominent features observed are highly time variable dust streams recorded

Dust Stream Measurements from Ulysses' Distant Jupiter Encounter

In 1992 the impact ionisation dust detector on board the Ulysses spacecraft discovered periodic burst-like streams of dust particles within 2AU from Jupiter. The streams occurred at approximately

Io as a source of the jovian dust streams

Io's volcanoes, rather than impact ejecta, are the dust sources of the jovian dust streams, on the basis of periodicities in the dust impact signal.

Dynamics, Composition, and Origin of Jovian and Saturnian Dust-Stream Particles

Stream particles are nanometer-sized dust particles ejected from the Jovian and Saturnian systems with speeds higher than 100\(\mathrm{{km\,s}}^{-1}\). Due to the large charge-to-mass ratio, their



Dust Measurements During Galileo's Approach to Jupiter and Io Encounter

About a hundred dust impacts per day were detected during the first week in December 1995 by Galileo during its approach to Jupiter. These impacts were caused by submicrometer-sized particles that

Mechanism for the acceleration and ejection of dust grains from Jupiter's magnetosphere

PERHAPS the most unexpected finding of the Ulysses mission so far has been the detection of quasi-periodic streams of high-velocity, submicrometre-sized dust particles during the spacecraft's

Ulysses dust measurements near Jupiter.

Dust flux measurements give evidence of the recent rates of production from sources such as comets, asteroids, and moons, as well as the possible presence of interstellar grains.

Constraints from Galileo observations on the origin of jovian dust streams

THE Ulysses spacecraft detected streams of sub-micrometre-sized dust particles as it approached Jupiter in 19921,2. Although interplanetary space was known to contain dust, the presence of discrete

Ulysses observations of a recurrent high speed solar wind stream and the heliomagnetic streamer belt

Near-ecliptic solar wind observations by Ulysses on its way to the polar regions of the Sun, compared with those from IMP 8 at 1 AU, showed that high-speed streams decay and broaden with heliocentric
