Astronauts Spending a Lot of Time Outside Space Station
Earlier this week, U.S. astronauts on the International Space Station ventured out of the station twice to successfully replace a cooling unit.
Rick Mastracchio and Mike Hopkins also managed to repair a spacesuit in order to complete the work. An ammonia cooling unit had failed, causing reduced activities in the orbiting habitat. The broken unit was removed on the first spacewalk (see photo), and astronauts installed a spare unit Christmas Eve. The station was starting to return to normal operations on Christmas Day.
Friday, December 27, the Russian cosmonauts were in spacesuits outside the ISS, hooking up cameras and other science equipment on the station hull. Sergey Ryazanskiy and Oleg Kotov were broadcast on NASA TV.
