Dec. 13, 2013— -- Living at the International Space Station can be difficult and even hazardous even in the best of times, but six astronauts are confined this week to just a handful of living modules after a cooling system had to be shut down because of temperature fluctuations.
NASA engineers are working around the clock in so-called "Tiger Teams" to isolate and find solutions to the cooling problems while astronauts on board prepare for a worst-case scenario: performing a space walk to fix a valve on the outside of the station.
