Sackett participates in NASA cold-atom experiment
Cass Sackett is a principal investigator and science team member in the NASA Cold Atom Lab project, in which ultra-cold atoms are produced and studied on the International Space Station. A report on the project has just been published in Nature, which describes the first production of a Bose-Einstein condensate in Earth orbit. The paper reports atoms cooled to temperatures below 1 nanoKelvin; Sackett is working on methods to make the atoms colder yet.
