Atom interferometers are reaching an exquisite performance and expected to be sensitive probes of fundamental interactions. Thanks to the clean environment and long observation times possible, space promises to unfold the full potential of such sensors. In this contribution, we report on the first realization of a cold atom experiment in space achieved by the sounding rocket mission MAIUS-1. Within 6 min of micro-g and 81 experiments, the chip-based BEC machine demonstrated a high degree of stability and a good agreement with quantum gases models. These results are a key milestone towards BEC-based space missions aiming for gravimetry, gradiometry, tests of fundamental physics laws or the detection of gravitational waves.
QUANTUS & MAIUS are supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant numbers DLR 50WM 1131-1137.
