One of the cooling systems on the International Space Station has shut down and may require a space walk to fix, NASA announced Wednesday.
“The crew was never in any danger,” NASA spokesman Josh Byerly told NBC News. “They worked to keep the freezers going. … They’re fine for the near future.”

Byerly said engineers think the problem was caused by a malfunctioning flow control valve for the station’s ammonia coolant. Mission managers are trying to determine whether a software fix can get the valve working again, or whether a spacewalk will be required. Sorting through the issues might take a couple days, or as much as a couple of weeks.
