In the Lab, CDR Fossum serviced the EarthKAM (EKAM/Earth Knowledge Acquired by Middle School Students) payload in the Lab WORF (Window Observation Research Facility) rack, changing battery after wakeup and twice more during the day. The requests are uplinked in a camera control file to the A31p SSC-20 (Station Support Computer) laptop which then activates the camera at specified times and receives the digital images from the camera's storage card on its hard drive, for... EKAM uses new software on SSC-20 which replaces the version used for the DCS 760 camera. [EK uses a NIKON D2Xs electronic still camera with 50mm and 180mm lenses, powered by a battery, taking pictures by remote operation from the ground, without crew interaction. This is the 3rd use of the D2Xs camera by EKAM. The camera battery is changed when no pictures are being taken. It is available for students who submit image requests and conduct geographic research.
