Space Missions: Interplanetary Dust

Scientific paper

ESA's PROBA-1 mission was launched in October 2001 into polar low Earth orbit. Two DEBIE sensors were placed on the spacecraft to monitor the dust and debris flux. The DEBIE sensor utilises two independent detection techniques, and is an active sensor providing real time data. Two sets of wire electrodes, sensitive to impact generated ions and electrons respectively, are mounted in front of a thin aluminium foil (acting as the target plate). On the foil are two piezoelectric devices, which measure the momentum transfer of an impact. If penetration of the foil occurs, there is a third electron plasma detector electrode located behind the foil. The detector is completing its commissioning phase, and we describe how impacting particle masses and speeds, as well as original orbits can be constrained from the flight data.
