NASA's Cold Atom Laboratory: Four Years of Quantum Science Operations in Space

The Cold Atom Laboratory (CAL) is a quantum facility for studying ultra-cold gases in the microgravity environment of the International Space Station. It enables research in a temperature regime and force-free environment inaccessible to terrestrial laboratories. In the microgravity environment, obs...

Description
Summary:The Cold Atom Laboratory (CAL) is a quantum facility for studying ultra-cold gases in the microgravity environment of the International Space Station. It enables research in a temperature regime and force-free environment inaccessible to terrestrial laboratories. In the microgravity environment, observation times over a few seconds and temperatures below 100 pK are achievable, unlocking the potential to observe new quantum phenomena. CAL launched to the International Space Station in May 2018 and has been operating since then as the world's first multi-user facility for studying ultra\-cold atoms in space. CAL is the first quantum science facility to produce the fifth state of matter called a Bose-Einstein condensate with rubidium-87 and potassium-41 in Earth orbit. We will give an overview of CAL's operational setup, outline its contributions to date, present planned upgrades for the next few years, and consider design choices for microgravity BEC successor-mission planning.
