Two crew members of the International Space Station have successfully completed a repair in space. Five hours needed Chris Cassidy and Tom Marshburn to fix a leak in the cooling system.
divIn an hour-long outdoor use in all two U.S. astronauts have sealed a leak in the cooling system of the International Space Station. Chris Cassidy and Tom Marshburn had replaced a control box, a pump, said the U.S. space agency Nasa with on Saturday. “No leak, we bring Tom & Chris back in,” tweeted the Canadian ISS Commander Chris Hadfield thrilled. If it were a “complex and decisive day,” he had written before. The responsible for the Russian part of the ISS, Vladimir Solovyov, had spoken of a “very serious problem”.
On the night of Friday, NASA had announced that the ISS ammonia from escaping into space. The toxic gas is used for cooling an electric circuit to the human outpost in around 410 kilometers altitude. In response, the crew prepared to use unscheduled ago – rose to 14.44 clock EST Cassidy and Marshburn out
.
One of the eight awning had been shut down, the remaining seven, all of which have their own cooling systems, but worked normally. According to experts, the ISS also has sufficient energy reserves.
Approximately five and a half hours took the risky outdoor use. For both astronauts, it was always the third “space walk” – the first two they had done together. On the ISS monitored Hadfield and Russian cosmonaut Roman Romanenko, Pavel Vinogradov and Alexander Missurkin the maneuver.
In November 2012, a leak had occurred in the cooling system. Then installed two ISS crew members with an outside use a bypass line. The question was, first, whether the hole had appeared in the same place or if it was from a sliver of space debris.
