Galileo And Ulysses Dust Detectors
The Galileo and Ulysses Dust Detectors are almost identical dust instruments on the Galileo (spacecraft), Galileo and Ulysses (spacecraft), Ulysses missions. The instruments are large-area (0.1  m2 sensitive area) highly reliable impact ionization detectors of sub-micron and micron sized Cosmic dust, dust particles. With these instruments the interplanetary dust cloud was characterized between Venus’ and Jupiter's orbits and over the solar poles. A stream of interstellar dust passing through the planetary system was discovered. Close to and inside the Jupiter system streams nanometer sized dust particles that were emitted from volcanoes on Jupiter's moon Io (moon), Io and ejecta clouds around the Galilean moons were discovered and characterized. Overview Following the first dust instruments from the Max Planck Institute for Nuclear Physics (MPIK), Heidelberg (Germany) on the European Space Research Organisation , HEOS 2 satellite and the Helios spacecraft a new dust ins ...
