We explore the feasibility of a quantum test of the Einstein equivalence principle with a dual species atom interferometer in space. The precision of such an experiment can be enhanced by the extended free fall of the matter waves in the interferometer. Goals of the sounding rocket mission MAIUS-2 are the generation of K-41 and Rb-87 BECs and the first demonstration of Raman based matterwave interferometry in space. The design builds on the MAIUS-A experiment [1]. The new system has been commissioned and qualified on ground and first results on ground-based cooling of alkaline atoms are presented.
