Fallturm Bremen is a drop tower at the Center of Applied Space Technology and Microgravity at the University of Bremen in Bremen. It was built between 1988 and 1990, and includes a 122-metre-high drop tube (actual drop distance is 110 m), in which for 4.74 seconds (with release of the drop capsule), or for over 9 seconds (with the use of a catapult, installed in 2004) weightlessness can be produced. The entire tower, formed out of a reinforced concrete shank, is 146 metres high. The 122-metre drop tube is free-standing within the concrete shell, in order to prevent the transmission of wind-induced vibrations, which could otherwise result in the airtight drop capsule hitting the walls. The drop tube is pumped down prior to every free-fall experiment to about 10 Pa (~ 1/10 000 atmosphere). Evacuation takes about 1.5 hours.

Max Planck Institute for Marine Microbiology

The Max Planck Institute for Marine Microbiology is located in Bremen, Germany. It was founded in 1992, almost a year after the foundation of its sister institute, the Max Planck Institute for Terrestrial Microbiology at Marburg. In 1996, the institute moved into new buildings at the campus of the University of Bremen. It is one of 80 institutes in the Max Planck Society (Max Planck Gesellschaft). Currently, the institute consists of three departments with several associated research groups: Biogeochemistry (headed by Dr. Marcel Kuypers) Molecular Ecology (headed Prof. Dr. Rudolf Amann) Symbiosis (headed by Prof. Dr. Nicole Dubilier)Additionally, the following research groups reside in the institute. Microbial Physiology (headed by Dr. Boran Kartal) Greenhouse Gases (headed Dr. Jana Milucka) Microbial Genomics and Bioinformatics (headed by Prof. Dr. Frank Oliver Glöckner) Flow Cytometry (headed by Dr. Bernhard Fuchs) Metabolic Interactions (headed by Dr. Manuel Liebeke) Microsensors (headed by Dr. Dirk de Beer) HGF MPG Joint Research Group for Deep-Sea Ecology and Technology (headed by Prof. Dr. Antje Boetius) MARUM MPG Bridge Group Marine Glycobiology (headed Dr. Jan-Hendrik Hehemann) Max Planck Research Group Microbial Metabolism (headed by Dr. Tristan Wagner) Marine Geochemistry Group (headed by Prof. Dr. Thorsten Dittmar) Max Planck Research Group for Marine Isotope Geochemistry (headed by Dr. Katharine Pahnke-May)
