This is a 3-D image of crews in Orbiter Processing Facility-2 at NASA's Kennedy Space Center in Florida using a Hyster forklift to lower one of space shuttle Discovery's main engines after removal for cleaning and inspection. This is part of the spacecraft's transition and retirement processing and work performed on Discovery is expected to help rocket designers build next-generation spacecraft and prepare the shuttle for future public display. To view this image, use green and magenta 3-D glasses. Photo credit: NASA/Frankie Martin
