Polar is a research refrigerator designed and developed by University of Alabama at Birmingham (UAB) Center for Biophysical Sciences and Engineering (CBSE) for NASA Cold Stowage. Polar was designed as a single mid-deck locker equivalent[further explanation needed] payload to store scientific samples on-board ISS and in transport to/from ISS via SpaceX Dragon or Cygnus spacecraft. Polar operates between 4 to −95 °C (39 to −139 °F).[1][2]
Description
- Polar is mounted in the ISS on the EXpedite the PRocessing of Experiments to Space Station (EXPRESS) rack.
- Polar can maintain temperatures ranging from 4 to −95 °C (39 to −139 °F).
- Polar is air-cooled via rear-air fan.
