NASA is working to contain a small leak onboard the International Space Station.
The issue appears to be contained and the people on board the station do not appear to be under any immediate threat. But it did trigger a real alarm through the floating lab, which sent astronauts scrambling to find the cause of the problem.
The crew was forced to check for the source of the leak by closing separate modules on the space station and finding which of them may be damaged. It was eventually tracked down in part of the Soyuz MS-09 spacecraft, which arrived at the station in early June carrying a crew of astronauts.
