The 15-year-old International Space Station suffered a cooling system failure on Wednesday evening, but NASA officials insist, for now, the crew is safe, and "there are no major concerns."
The cooling system pump shut down in response to low temperatures. A NASA spokesperson told Mashable that crews are currently investigating the cause of the low temperature, however they think it's likely the result of the radiator, which was at -75 degrees.
Our source said a spacewalk may be needed to determine the problem, and there is a contingency plan in place.
"The teams want to understand the system performance before activating the system. A flow control valve is not operating as anticipated. The teams are trying to understand what they are seeing," the spokesperson said. "The team may power off selected components to avoid over heating while they watch the flow control valve and temperature control capability." We will update this story as more information becomes available.
