The Center of Applied Space Technology and Microgravity (ZARM) is an institute of the faculty of Production Engineering at the University of Bremen. The institute was founded in September 1985 and focused initially on the investigation of flow phenomena under microgravity conditions and the development of space technology. Today ZARM is an internationally recognized research center with multidisciplinary expertise in fluid mechanics, space technology and space science. The research at ZARM covers experimental, theoretical, and computational approaches to fundamental scientific questions, as well as the development of technology for space missions and microgravity experiments (for example on the International Space Station). ZARM employs more than 100 scientists, engineers, and administrative staff and hosts many students from the faculty of Production Engineering, as well as from the Physical Sciences and Information Technology departments.The main facility of ZARM is the Bremen Drop Tower. With its 146-meter drop tower facility is not only a technological landmark of Bremen but unique in Europe, and offers scientists from all over the world the possibility to perform experiments in microgravity. The drop tower’s 9.3-second test duration is the longest in the world, and is a cost-effective and permanently accessible option for experimentation under space conditions.Furthermore, ZARM within the context of its test center capabilities operates the largest centrifuge in Europe which enables tests and certifications of aerospace structures as well as prototypes under conditions of increased gravity.Finally, in the in-house thermal vacuum chambers and the vibration test laboratory, space components can be tested under realistic settings. These diverse further test facilities of ZARM Test Center can help to ensure in advance that components will be fully functional in space.
