A facility designed to fly aboard the International Space Station, the Cold Atom Laboratory, or CAL, will make use the space station's unique microgravity environment to observe quantum phenomena that would otherwise be undetectable from Earth. The laboratory will be available for use by multiple scientific investigators and is designed to be maintained on orbit.

The Cold Atom Laboratory launched successfully and was installed on the International Space Station in May 2018, serves as an experiment in the use of laser-cooled atoms for future quantum sensors.
