CAPE CANAVERAL, Fla. -- The Solid Rocket Booster Retrieval Ship Freedom Star, with a booster in tow, is docked in Port Canaveral in Florida before continuing on to Hangar AF at Cape Canaveral Air Force Station. A cruise ship is seen in the background. The booster was used during space shuttle Discovery's STS-133 launch from NASA Kennedy Space Center's Launch Pad 39A on Feb. 24. The shuttles two solid rocket booster casings and associated flight hardware are recovered in the Atlantic Ocean after every launch by Liberty Star and Freedom 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.
