Live coverage: Space station crew investigating slow pressure leak

An apparent exterior coolant leak from a Russian laboratory module at the International Space Station has been reported by the crew. It follows similar leaks that struck a Russian Soyuz crew ferry craft and a Progress cargo ship within the past year.

With three space station fliers heading home Sunday after a 168-day mission, three fresh crew members made final preparations for launch three days later to boost the lab’s crew back to six in a rapid-fire rotation that will prevent any major interruption of research activity.
