The Ex edition 42 crew members are safe and in ood sha e inside the Russian se ment of the International Space Station following an alarm in the U.S. segment at about 4 a.m. EST.
Flight controllers in Mission Control at NASA’s Johnson Space Center in Houston saw an increase in pressure in the station’s water loop for thermal control system B then later saw a cabin pressure increase that could be indicative of an ammonia leak in the worst case scenario. Actin conservativel to protect for the worst case scenario, the crew was directed to isolate themselves in the Russian se ment while the teams are evaluatin the situation. Nonessential equipment in the U.S. segment of the station was also powered down per the procedures.
In an exchan e at 7:02 a.m. with Ex edition 42 Commander Barr Wilmore of NASA, s acecraft communicator James Kelly said flight controllers were analyzing their data but said it is not yet known if the alarm was actually triggered by a leak or whether the situation was caused by a faulty sensor or by a problem in a computer relay box that sends data and commands to various systems on the station.
