IN SPACE - MAY 29: In this handout provided by National Aeronautics and Space Administration (NASA), back dropped by planet Earth the International Space Station (ISS) is seen from NASA space shuttle Endeavour after the station and shuttle began their post-undocking relative separation May 29, 2011 in space. After 20 years, 25 missions and more than 115 million miles in space, NASA space shuttle Endeavour is on the last leg of its final flight to the International Space Station before being retired and donated to the California Science Center in Los Angeles. Capt. Mark E. Kelly, U.S. Rep. Gabrielle Giffords' (D-AZ) husband, has lead mission STS-134 as it delivered the Express Logistics Carrier-3 (ELC-3) and the Alpha Magnetic Spectrometer (AMS-2) to the International Space Station.

WASHINGTON (AP) -- The International Space Station has a radiator leak in its power system. The outpost's commander calls the situation serious, but not life-threatening.

   The six-member crew on Thursday noticed white flakes of ammonia leaking out of the station. Ammonia runs through multiple radiator loops to cool the station's power system. NASA said the leak is increasing from one previously leaking loop that can be bypassed if needed. NASA spokesman Bob Jacobs said engineers are working on rerouting electronics just in case the loop shuts down. The Earth-orbiting station has backup systems.

   Space station Commander Chris Hadfield of Canada tweeted that the problem, while serious, was stabilized. Officials will know more Friday.

   The space station always has enough emergency escape ships for the crew, but there are no plans to use them.
