We experimentally demonstrate the possibility of preparing ultracold atoms in the environment of weightlessness at the earth-bound short-term microgravity laboratory Drop Tower Bremen. Our approach is based on a freely falling magneto-optical trap (MOT) drop tower experiment performed within the ATKAT collaboration (Atom-Catapult) as a preliminary part of the QUANTUS pilot project (Quantum Systems in Weightlessness) pursuing a Bose-Einstein condensate (BEC) in microgravity at the drop tower. We give a complete account of the specific drop tower requirements and present the results of the realized freely falling MOT and further accomplished experiments during several drops.
