Live coverage: Space station crew investigating slow pressure leak
Crew members aboard the International Space Station are investigating a tiny pressure leak on the Russian side of the orbiting outpost. The crew traced the leak to a small hole on the Soyuz MS-09 spacecraft, which ferried a three-person crew to the station in June. Mission control is examining options to repair the damage, and NASA says the crew is not in danger.
