The Bremen drop tower is a drop tower completed in Bremen in 1990, operated by the Center for Applied Space Technology and Microgravity (ZARM) in the Department of Production Engineering at the University of Bremen. It is unique in Europe and enables ground-based experiments under short-term weightlessness.

The Bremen drop tower is 146 meters high and has a 120-meter high, evacuated drop tube inside, in which a drop capsule falls 110 m for 4.74 seconds. Weightlessness prevails in the capsule during this time. The capsule's time in zero gravity can be extended to over 9 seconds using the catapult installed in 2004. Depending on the space required for the respective experiment, the capsule has a diameter of 0.8 meters and a length of 1.6 meters or 2.4 meters. It falls into an 8-meter-tall receptacle filled with pinhead-sized foam polystyrene balls.

The drop tower consists of a cylindrical reinforced concrete shaft with a conical tip. Inside the tower is a free-standing steel tube, the actual fall area, which is decoupled from the wind-related fluctuations in the outer shell.
