Weightlessness Bose-Einstein Condensates (BEC) feature new possibilities for analysing the non-classical behaviour of condensed quantum systems. New temperature records due to the possibility of the complete adiabatic expansion as well as the coherent evolution of the condensate in the second time scale should be reached in a weightlessness environment. The aim of the project is a feasibility study of the technical realisation of a compact, robust and mobile experiment for the creation of a BEC, which can withstand high forces in a droptower. (Cooperation with the center of applied space flight and microgravity, ZARM, University of Bremen). The Experiment has to withstand forces up to 50 g, The whole setup is implemented in a drop-capsule (length without cone end 215 cm), where all components, including power supply and experiment control computer, are implemented. The compact setup is realised by an Atom-Chip (Jakob Reichel, MPQ München)  and a robust DFB-diode laser system. Thus the use of fiber technologies allows a setup with different "stand alone" parts, coupled via optical fibers.
