MV Freedom Star

MV Freedom Star was a NASA-owned and United Space Alliance-operated vessel which served as an SRB recovery ship following the launch of Space Shuttle missions. It performed tugboat duties and acted as a research platform. In 2012 it was transferred to the U. S. Department of Transportation as part of the James River Reserve Fleet, her sister ship is the MV Liberty Star. The recovery ships were built at Atlantic Marine Shipyard on Fort George Island and delivered in January 1981 to their original owner, United Technologies Corporation; as well as recovering the Space Shuttle SRB's Freedom Star has since 1998 been used to tow the Space Shuttle external fuel tanks from their assembly plant at Michoud Assembly Facility near New Orleans, Louisiana, to the Vehicle Assembly Building at the Kennedy Space Center in Florida. She served a similar role in recovering the first test flight of the Ares I and was anticipated to continue recovering boosters for the Constellation program before it was canceled in 2010.

Freedom Star underwent special strengthening enhancements to withstand the greater burden of towing the external fuel tanks. The stern was strengthened at critical points, new bulwark fairings were added, an H-bitt was installed through which cabling is threaded to keep it centered during towing operations. Installed was a hydraulic towing winch, referred to as a double-drum waterfall winch, holding 2,000 feet or more of wire rope on each drum. One drum supports booster retrievals. Freedom Star has occasionally been used to support scientific research operations including research for the National Oceanic and Atmospheric Administration and several universities, she is docked alongside her sister at the Solid Rocket Booster processing facility at the Cape Canaveral Air Force Station in Florida. Each ship is propelled by two main engines providing a total of 2,900 horsepower; the main engines turn two seven-foot propellers with controllable pitch, which provides greater response time and maneuverability.

The ships are equipped with two thrusters. The stern thruster is a water jet system that allows the ship to move in any direction without the use of propellers; this system was installed to protect the endangered manatee population that inhabits regions of the Banana River where the ships are based. The system allows divers to work near the ship during operations at a reduced risk. In April 2012, NASA used Freedom Star to track a commercial orbital spaceflight by a Falcon 9 launch vehicle flown to the International Space Station by their space transport contractor SpaceX. On September 28, 2012, Freedom Star was transferred to the U. S. Department of Transportation's James River Reserve Fleet for potential use as a training vessel.
