Matter wave interferometry allows for quantum sensors with a wide range of applications, e.g. in geodesy or tests of fundamental physics. As a testbed for future space missions, the QUANTUS-2 experiment enables rapid BEC production of Rb-87 atoms with 105 atoms and performs atom interferometry in free fall at the ZARM drop tower in Bremen. In combination with a magnetic lens, we are able to reduce the total internal kinetic energy to 38pK in three dimensions [1]. Here, we present the latest results on our single species interferometry experiments and an outlook on the integration of a potassium laser system, which will open up the possibility to study and manipulate quantum gas mixtures, as well as to perform dual species atom interferometry in microgravity. This project is supported by the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Energy (BMWi) under grant numbers DLR 50WM1952-1957.
