KENNEDY SPACE CENTER, FLA. - The starboard side of orbiter Endeavour is shown as it sits inside the Florida Space Authority’s Reusable Launch Vehicle hangar at NASA’s Kennedy Space Center. While in the hangar, Endeavour has undergone testing to see how orbiters respond to a new radar system that will be used during launch to detect debris. Endeavour is returning to the Orbiter Processing Facility today to continue Orbiter Major Modifications (OMM). OMMs are scheduled at regular intervals to enhance safety and performance, infuse new technology, and, in this case, perform Return to Flight modifications.
