A major short circuit has occurred in International Space Station. Spacewalk is required to repair this problem with replacing the problematic part through rocket.

According to NASA, six astronauts went with having only one less power channel on Friday. The short exactly stripped a current-switching device after that one channel loss from eight channels from the power orbiting lab and then systems which were affected changed to rotate lines.

Spokesman Dan Huot of NASA added that crew were operating normally and there is no danger. This kind of failures happened in 2014, at that time also spacewalking needed to repairs.

There is now good spare part for the job on board so that NASA is planning to start a replacement on a SpaceX and delivery schedule will be in next year, said Huot. After failing SpaceX launch in July has been grounded.

Remaining orbital grounded at Wallops Island, Virginia from the October 2014 accident. Now, it is relying on other rocket makers for delivering goods from Cape Canaveral on Dec 3 on board an Atlas V.
