ISS015-E-18967 (23 July 2007) --- An Early Ammonia Servicer (EAS) moves away from the International Space Station after it was jettisoned by astronaut Clay Anderson (out of frame), Expedition 15 flight engineer, during today's session of extravehicular activity (EVA). The EAS was installed on the P6 truss during STS-105 in August 2001, as an ammonia reservoir if a leak had occurred. It was never used, and was no longer needed after the permanent cooling system was activated last December.
