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 streams was completely unexpected. The directions from which the dust grains struck the spacecraft strongly suggested that the source lay somewhere within the Jupiter system. Three origins were proposed, the comet Shoemaker–Levy 9 (ref. 3), Jupiter's gossamer ring4, and the volcanoes on Io5, but… 

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.

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

Dust en-route to jupiter and the galilean satellites

One year of Galileo dust data from the Jovian system: 1996


Dust was observed in the Jovian magnetosphere with the dust detector onboard the Galileo spacecraft. Measurements have been obtained inside a distance of about 100Rj from Jupiter’s center (Jupiter

The cosmic dust analyser onboard cassini: ten years of discoveries

The interplanetary space probe Cassini/Huygens reached Saturn in July 2004 after 7 years of cruise phase. The German cosmic dust analyser (CDA) was developed under the leadership of the Max Planck

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.

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



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

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

Dust streams from comet Shoemaker-Levy 9?

In 1991 and 1992, the dust detector onboard the Ulysses spacecraft detected several dust streams apparently originating from the jovian system. The timing and measured speeds of the final two dust

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

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

Spatial color variations in the volcanic plume at Loki, on Io

Multicolor Voyager 1 photographs of the Loki volcanic plume, on Io, have been analyzed to determine the nature and quantity of the scattering material within the plume. This work indicates that there

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
