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.
Institution: LASP, University of Colorado
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.
