The MAIUS (Matter wave interferometry under microgravity) project aims to demonstrate atom interferometry in space as a promising tool for precision measurements, e.g., of Einstein's equivalence principle (EEP), with accuracies that couldn't be achieved with classical tests. With the launch of MAIUS-1, it was possible to create the first BECs in space using Rb-87 atoms and performing interference experiments with these macroscopic quantum objects. In the MAIUS-2/3 missions, we concentrate on the understanding of the dynamics of K-41 and Rb-87 quantum mixtures in microgravity and to utilize them as sources for dual species atom interferometry in space. This contribution focuses on the mission goals, simulation results of quantum mixture density profiles, transport of mixtures considering gravitational effects and preparation of mixtures using delta-kick cooling for further reduction of the momentum spread. These techniques are important prerequisites to perform EEP tests with BECs created on an atom chip under microgravity. The MAIUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number: 50WP1431.
