Abstract
Results from the first direct rocket probe measurements of the current s due to impacting mesospheric dust are reported. The observations whi ch are corrected for production of secondary electrons during impact s how that dust is a major charge carrier during polar mesosphere summer echo (PMSE) conditions and that the charge density of the dust can va ry strongly over a vertical distance of several meters only. The dust is negatively charged in the reported case. Copyright (C) 1996 Elsevie r Science Ltd
