We briefly describe a “third generation” follow-on to the Cold Atom Lab (CAL) mission, currently operating aboard the ISS and the Bose—Einstein Condensate and Cold Atom Lab (BECCAL) mission, which is expected to launch in 2026. This mission would feature a modular design that would allow critical hardware to be optimized for specific investigations while allowing easy exchange with other hardware to enable a multi-user facility.
