The International Space Station (ISS) will be repaired after the failure of a cooling pump. Therefore, the U.S. space agency Nasa also shifted the supply air of a private van. On 21, 23 and 25 December to march out two astronauts to more than six hours long spacewalks to replace the pump, said the Nasa.

On Saturday, the U.S. astronauts Rick Mastracchio and Mike Hopkins will start at 13.10 CET the first outdoor use. The planned originally for Wednesday launch of commercial space shuttle “Cygnus”, which was approximately 1300 kg replenishment fly on board the ISS, has been moved to “the earliest in January.” The crew can thus probably spend Christmas at home.

The six-man crew and the station are but according to NASA not in danger. With the announced field operations, the astronauts Hopkins and Mastracchio to remove the defective pump and install an existing spare part.

The defective valve is necessary for regulating the temperature of the air conditioning. On the ISS, there is a second cooling circuit is functioning normally. Are affected by the partial failure, according to NASA, the Harmony module of the ISS, the Kibo laboratory and the European Columbus laboratory.
