Crew members attach a tow rope to the parachute lines from the right spent booster bobbing in the Atlantic Ocean.

Crew members in a skiff from Liberty Star, one of NASA's solid rocket booster retrieval ships, attach a tow rope to the parachute lines from the right spent booster bobbing in the Atlantic Ocean from 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/Frank Michaux
