Cold Atom Laboratory (CAL)

CAL is a fundament physics user facility that will operate on the International Space Station (ISS). CAL will produce clouds of ultra-cooled atoms called Bose-Einstein condensates. Chilled to a fraction of a degree above absolute zero -- even colder than the average temperature of deep space -- the atoms in a BEC demonstrate quantum characteristics at relatively large size scales, allowing researchers to explore this strange domain.

On Earth, freely evolving BEC’s are dragged down by the pull of gravity, and can typically only be observed for a fraction of a second. But in the microgravity environment of the space station, each freely evolving BEC can be observed for up to 10 seconds, which is longer than what’s possible with any other existing BEC experiment. CAL is a multi-user facility and researchers will be able to conduct experiments remotely, with no astronaut assistance, with up to 6.5 hours of experimentation time available each day.

CAL is currently set to launch to the ISS on May 20, 2018, aboard an Orbital ATK Cygnus spacecraft, atop an Antares rocket, from NASA’s Wallops Flight Facility in Virginia.

Der Start wurde des Wetters wegen auf Montag 10:39 MESZ verschoben:

NASA has rolled the OA9 launch out of Wallops back to Monday morning at 8:39 UT/4:39 AM EDT due to weather.

Space station experiment reaches ultracold milestone

The graph shows the changing density of a cloud of atoms as it is cooled to lower and lower temperatures (going from left to right) approaching absolute zero. The emergence of a sharp peak in the later graphs confirms the formation of a Bose-Einstein condensate—a fifth state of matter—occurring here at a temperature of 130 nanoKelvin, or less than 1 Kelvin above absolute zero.
