NASA’s CAL hosts multiple experiments that explore the fundamental nature of atoms by cooling them down to nearly absolute zero (the coldest temperature matter can reach). Science Module 3X increases the number of atoms produced for each experiment and allows scientists to gather more data and further expand the Cold Atom Lab’s research capabilities.
