Title: In-Situ Mass Spectrometry of Atmosphereless Planetary Objects
Primary Author: Eberhard Gruen
Secondary Author(s): Frank Postberg, Harald Krüger, Mihaly Horanyi, Elmar Jessberger Sascha Kempf, Ralf Srama, Thomas Stephan, Zoltan Sternovsky
Institution: LASP, University of Colorado
Summary: Dust particles emitted from atmosphereless planetary objects are samples of their surfaces. By mass analyzing these particles and tracing back their trajectories to their sources the surface composition of Mercury, planetary satellites, dusty rings sources, asteroids and comets can be obtained.
Panel Selection: Inner Planets: Mercury, Venus, and the Moon.
Giant Planets: Jupiter, Saturn, Uranus, Neptune, and exoplanets, including rings and magnetic fields, but not their satellites.
Satellites: Galilean satellites, Titan, and the other satellites of the giant planets.
Primitive Bodies: Asteroids, comets, Phobos, Deimos, Pluto/Charon and other Kuiper belt objects, meteorites, and interplanetary dust.
