With the launch of the MUSES B spacecraft a new concept for a large deployable antenna structure has been put into orbit. The antenna is made out of a gold plated molybdenum mesh The diameter of a single mesh fiber is about 30 micrometer. It is the thinness of the fibers which has led to the investigation on whether the space debris environment will affect the performance of the antenna. While the mechanical interaction is in principal understood, little is known about the electromagnetic aspects of the debris problem. The Institute of Space and Astronautical Sciences has therefore started to investigate the electromagnetic aspects of the debris impact problem. This study serves mainly the purpose to learn whether electromagnetic interference between the impact generated plasma cloud will influence the receiver performance of the satellite (and thereby its scientific output) and to explore the possibility on whether such an antenna/receiver system can be utilized for the detection and characterization of the debris environment. The first point will be of interest to all space based radio astronomical observatories (incl. those put onto the lunar surface) and the second point will be of interests to all areas where thin film structures shall be employed, e.g. thin film solar cell arrays. Preliminary experimental results will be presented in this article.
