The Solar system is a complex gathering of nine planets, more than 80 moons and countless asteroids, comets and Kuiper Belt objects circling the Sun in more or less elliptic orbits. Filled by magnetic fields, radiation of all kinds and a steady stream of charged solar wind particles. For about 40 years now mankind investigates this unknown region with space probes, adding to our knowledge from ground based telescopic observations and theoretical studies with in-situ measurements. Again and again we encounter new puzzles and new wonders, which stimulate human curiosity and interest.

On the following web pages you can read about the numerous contributions of the Graz Space Research Institute to a multitude of missions into and studies about the Solar system.
