The Cassini Cosmic Dust Analyzer

TL;DR: The Cassini-Huygens Cosmic Dust Analyzer (CDA) 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 and satumian systems, to investigate their physical, chemical and dynamical properties as functions of the distances to the Sun, to Jupiter and to Saturn and its satellites and rings as mentioned in this paper.
Journal ArticleDOI

High-velocity streams of dust originating from Saturn

TL;DR: 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.
Journal ArticleDOI

Composition of saturnian stream particles.

TL;DR: During Cassini's approach to Saturn, the Cosmic Dust Analyser discovered streams of tiny high-velocity dust particles escaping from the saturnian system, which implies that the particles are impurities from the icy ring material rather than the ice particles themselves.
Journal ArticleDOI

Interstellar dust flux measurements by the Galileo dust instrument between the orbits of Venus and Mars

TL;DR: In this paper, an analysis of the data obtained by the Galileo in situ dust instrument for interstellar dust (ISD) is presented, where the authors infer that the flux of ISD grains between 0.7 AU and 3 AU is about 4 × 10 -5 m -2 s -1.
