Gallery: Discovery getting her replica engines
In preparation for displaying the space shuttle Discovery at the Smithsonian's National Air and Space Museum Steven F. Udvar-Hazy Center, technicians began installing replica main engines on Monday.
Using previously-flown nozzles from old-generation engines, the replicas don't include the internal turbopumps, controllers or other parts. NASA is keeping its current-generation engines in protective storage for use aboard the future Space Launch System heavy-lift rocket
Monday's installation saw the Pratt & Whitney Rocketdyne-made engine get hauled from the prep shop over to Orbiter Processing Facility bay 1 and get inserted into Discovery's center-engine position.
