Astronauts Make Critical Repairs to Space Station
Zee News reports US astronauts successfully fixed a faulty cooling system on Tuesday working outside the International Space Station (ISS).
NASA astronauts Rick Mastracchio and Mike Hopkins completed their second spacewalk in four days spending a time of 7.5 hours outside the ISS to replace the critical cooling system, says Zee News.
As they were installing a spare cooling pump, adds Zee News, a sprinkling of ammonia crystals leaked out from one of four fluid lines. The toxic liquid turns to flakes in the cold and weightlessness environment of space.
