A great variety of fundamental physics experiments greatly benefit from a microgravity environment, as can be found aboard a sounding rocket or a satellite. To enable quantum optics experiments on these platforms, a laser system is required that exhibits high thermal stability, is mechanically very robust and compact. To this end, we have developed an optical bench technology based on the glass-ceramic Zerodur, which exhibits an almost negligible coefficient of thermal expansion. The presented technology was successfully implemented in the scope of the sounding rocket missions KALEXUS, FOKUS and MAIUS-1, and will enable future missions such as MAIUS-2/3, as well as the NASA-DLR BECCAL mission aboard the ISS. The poster discusses the optical modules used in these missions and how they have been used to help achieve major experimental milestones such as the first creation of a Bose-Einstein condensate in space.
