In this unique time-lapse video created from thousands of individual frames, photographers Scott Andrews, Stan Jirman and Philip Scott Andrews condense six weeks of painstaking work into 3 minutes, 52 seconds.The action starts in the hangar-like Orbiter Processing Facility at NASA’s Kennedy Space Center, where Discovery has been outfitted for its STS-131 mission.This is the stuff you never see as can be seen here. ¡Enjoy it¡
