CAPE CANAVERAL, Fla. -- Workers monitor the progress of the solid rocket booster retrieval ship Freedom Star as it tows a left spent booster to the dock at Hangar AF on Cape Canaveral Air Force Station in Florida. The booster was used during space shuttle Discovery's final launch. The shuttle's two solid rocket booster casings and associated flight hardware are recovered in the Atlantic Ocean after every launch by Freedom Star and Liberty Star. The boosters impact the Atlantic about seven minutes after liftoff and the retrieval ships are stationed about 10 miles from the impact area at the time of splashdown. After the spent segments are processed, they will be transported to Utah, where they will be refurbished and stored, if needed. Photo credit: NASA/Jim Grossmann
