Space offers a unique low-noise, low-gravity environment necessary for deploying competitive quantum sensors covering a wide spectrum of applications ranging from time and frequency transfer to Earth observation and the exploration of fundamental laws of physics. In this contribution, we report about the CUAS consortium activities within the NASA Cold Atom Lab stationed aboard the International Space Station. It consists of a multi-user Bose-Einstein Condensate facility continuously operating in-orbit. The outcome of a year of operations is presented and their significance for follow-up missions testing general relativity, quantum mechanics or cosmology predictions is highlighted.
