Ammonia leak detected outside International Space Station

REUTERS - An ammonia leak was detected Thursday in the cooling system outside of the International Space Station, but no crew members were in danger as a result, the U.S. space agency NASA said on its website. The agency said that fixing the leak might require that a portion of the station’s cooling system be shut down for about 48 hours. It was not clear whether the leak, which officials said appeared to be getting worse, was related to a similar in late 2012. (Reporting by Sharon Bernstein; Editing by Cynthia Johnston)
