International Space Station Operations Update
At approximately 1 p.m. EDT Oct. 9, NASA flight controllers in mission control at the agency?s Johnson Space Center in Houston, using cameras on the International Space Station exterior, observed flakes emanating from one of two radiators on the Roscosmos Nauka Multipurpose Laboratory Module (MLM). The flight control team informed the crew aboard the space station of the potential leak, and NASA astronaut Jasmin Moghbeli confirmed the presence of the flakes from the cupola windows, after which the crew was asked to close the shutters on U.S. segment windows as a precaution against contamination. The crew aboard station was never in any danger. Roscosmos confirmed that the observed leak is on Nauka?s backup radiator, which is mounted to the outside of the module. The radiator was delivered to the space station on the Rassvet module during space shuttle mission STS-132 in 2010. It was transferred to the Nauka during a Roscosmos spacewalk in April. The primary radiator on Nauka is working normally, providing full cooling to the module with no impacts to the crew or to space station operations. Teams on the ground will continue to investigate the cause of the leak, and additional updates will be made as available.
