EVA Plans Hit A Snag

Space Station EVA Unable To Remove Failed Ammonia Pump – More EVAs Ahead
“The next spacewalk to complete the removal of a failed ammonia pump module and installation and activation of a new pump module on the International Space Station’s S1 Truss will take place no earlier than Wednesday. Expedition 24 Flight Engineers Doug Wheelock and Tracy Caldwell Dyson completed the first spacewalk to remove and replace the pump module at 3:22 p.m. EDT Saturday. As the result of an ammonia leak in the final line that needed to be disconnected from the failed pump module, the day’s tasks were only partially completed.”
