Abstract

The recent retrieval of the EURECA satellite and one solar array from the Hubble Space Telescope initiated meteoroid and debris impact investigations on these surfaces. This paper gives an overview of observations of impact sites found on retrieved spacecraft surfaces, hypervelocity test programs performed as part of the European Space Agency (ESA) post-flight investigation programs (PFIP), and develops empirical scaling laws for various geometric parameters. These empirical scaling laws are intended to relate particle parameters to crater dimensions to support the modeling of the microparticle environment in near-Earth space.
