Space-Enabled Quantum Science with NASA's Cold Atom Lab (CAL) Operating on the International Space Station

POSTER

Abstract

The CAL facility launched to the International Space Station (ISS) in May 2018, and has been operating since that time as the world’s first multi-user facility for the study of ultra-cold quantum gases in space. The unique microgravity environment of the ISS is utilized with CAL by a national group of principal investigators to achieve sub-nanokelvin temperature gases, to study and utilize their quantum properties in an environment free from the perturbing force of gravity, and to observe and interact with these gases in the essentially limitless freefall of Earth’s orbit. In addition to the toolbox of capabilities originally built into CAL, an upgrade in 2020 enabled the study of atom interferometry in orbit, and a 2021 upgrade and repair facilitated investigations of the interactions between mixtures of 87Rb, 39K, and 41K and dual-species (87Rb - 41K or 87Rb - 39K) atom interferometry. This poster will review the up-to-date quantum gas research explored with CAL and the technical accomplishments to operate, maintain, and upgrade CAL during its tenure in the microgravity environment of the ISS. This research has broad applications in fundamental physics and precision sensing to open the door for future quantum-enabled mission opportunities.

*Designed, managed and operated by Jet Propulsion Laboratory, Cold Atom Lab is sponsored by the Biological and Physical Sciences Division of NASA's Science Mission Directorate at the agency's headquarters in Washington and the International Space Station Program at NASA's Johnson Space Center in Houston.
