The Center of Applied Space Technology and Microgravity (ZARM) is part of the Department of Production Engineering at the University of Bremen. In September 1985 the institute was founded as a research center mainly focused on the investigation of phenomena under the condition of weightlessness and questions related to space technology. "Today ZARM is internationally established as a competent partner with a multidisciplinary expertise in space science and technology as well as fluid mechanics. It is involved in the theoretic approach to fundamental scientific questions as well as in the technological developments for space missions and the performance of microgravity experiments, e.g., on the ISS. ZARM employs more than 100 scientists, engineers and administrative staff and, in addition, hosts many students from different departments like production engineering, physical sciences or information technologies. The main laboratory of ZARM is the Bremen Drop Tower. It offers the opportunity for short-term experiments under high-quality microgravity conditions and is the only laboratory of this kind in Europe. Due to the very successful operation by the ZARM Drop Tower Operation and Service Company (ZARM FAB) the demand for drop tower experiments has continuously increased. Today the Bremen Drop Tower is usually booked out for one year in advance. "
