ON 8 February 1992, the Ulysses spacecraft flew by Jupiter at a distance of 5.4 AU from the Sun. During the encounter, the spacecraft was deflected into a new orbit, inclined at about 80° to the ecliptic plane, which will ultimately lead Ulysses over the polar regions of the Sun1. Within 1 AU from Jupiter, the onboard dust detector2 recorded periodic bursts of submicrometre dust particles, with durations ranging from several hours to two days, and occurring at approximately monthly intervals… 
The flux of interstellar dust observed by Ulysses and Galileo
Interstellar dust detected by the dust sensor onboard Ulysses was first identified after the Jupiter flyby when the spacecraft's trajectory changed dramatically (Grün et al., 1994). Here we report on
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 jovian latitude scan of high-velocity dust streams originating from the jovian system
Abstract In February 2004 the Ulysses spacecraft had its second flyby at Jupiter at 0.8 AU distance from the planet. Twenty-eight dust streams emanating from the jovian system were measured between
Magnetic field modulated dust streams from Jupiter in interplanetary space
Abstract High speed dust streams emanating from near Jupiter were first discovered by the Ulysses spacecraft in 1992. Since then the phenomenon has been re-observed by Galileo in 1995, Cassini in
Ejection of dust from Jupiter's gossamer ring
ONE of the most intriguing discoveries of the Ulysses mission so far has been the detection of periodic, collimated streams of high-velocity, submicrometre-sized dust particles emanating from
Jovian dust streams: probes of the Io plasma torus
[1] 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
Anticipation of the Ulysses Interstellar Dust findings
It has long been thought that dust particles making up the zodiacal cloud come predominantly from sources within the solar system such as short-period comets, asteroids, and Jupiter's moons. However,
Interstellar Dust in the Solar System
Abstract The Ulysses spacecraft has been orbiting the Sun on a highly inclined ellipse almost perpendicular to the ecliptic plane (inclination 79°, perihelion distance 1.3 AU, aphelion distance 5.4
Dust measurements during Ulysses' 2nd Jupiter encounter
In 2004 the Ulysses spacecraft had its second flyby at Jupiter at 0.8 AU from the planet. 28 dust streams emanating from the jovian system were identified over a 26-month period while the spacecraft
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.


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.
Galileo and Ulysses dust measurements: Fz Venus to Jupiter
The Galileo and Ulysses spaceprobes carry two similar dust detectors through interplanetary space from Venus to Jupiter. We report here on impacts which correspond to dust particles above a mass
The Galileo dust detector
The Galileo Dust Detector is intended to provide direct observations of dust grains with masses between 10−19 and 10−9 kg in interplanetary space and in the Jovian system, to investigate their
The motion of charged dust particles in interplanetary space—II. Interstellar grains
Abstract The effects of electromagnetic forces on charged interstellar grains entering the heliosphere are re-examined. It is shown that the unipolar field regimes at high latitudes lead either to a
Low-frequency Jovian emission and solar wind magnetic sector structure
The Earth, Jupiter and Saturn emit non-thermal low-frequency radiations with similar characteristics. For the Earth and Saturn, the radio emissions are known to fluctuate with a time scale of several
Dust in Jupiter's magnetosphere - An Io source
The possibility of removing particles from Io by interactions with the Jovian magnetosphere has been investigated. It is found that dust grains of about 0.1 micron radius will rapidly become charged
Physical processes in Jupiter's ring - Clues to its origin by Jove
Abstract The particles making up the Jovian ring may be debris which has been excavated by micrometeoroids from the surfaces of many unseen ( R ≲ 1 km) parent bodies (or “mooms” as we will

Dust in jupiter's magnetosphere: Origin of the ring
Abstract A model for the production of the Jovian ring is proposed. The ‘visible’ ring particles are micron-sized and produced by erosive collisions between an assumed population of km-sized parent
Streaming of interstellar grains in the Solar System
Deep-space probes offer excellent opportunities to study interstellar grains streaming into the Solar System. Direct detection of such particles would considerably add to our knowledge in many areas
