Research project

Cold Atom Space PAyload (CASPA)

Project overview

New developments in Quantum Technology have resulted in the ability to cool atoms close to absolute zero using lasers. At these extreme temperatures, laboratory experiments have shown that these cold atoms can be used as ultra-sensitive sensors for measuring gravity. The objective of this project is to take the technology out of the laboratory and build it into a small satellite payload that is capable of producing cold atoms in space. Demonstrating this new technology in space is a vital first step towards realising real instruments that are capable of mapping tiny changes in the strength of gravity across the surface of the earth. The extreme sensitivity brought by cold atom sensors will provide the ability to finely monitor the movement of mass within earth systems. This has multiple applications including accurate monitoring of changes in polar ice mass, ocean currents and sea level. Higher resolution data will lead to the ability to monitor smaller water sources and new underground natural resources which are currently not detectable. Similar technology will also be used for deep space navigation and for providing higher precision timing sources in space.
