NASA release
NASA Awards Contract for Mobile Launcher

NASA's Kennedy Space Center has awarded a contract to Hensel Phelps of Orlando, Fla., for the construction of a new mobile launcher for the Constellation Program. The contract includes an option for an additional mobile launcher. It is a firm fixed-price contract with a value of $263,735,000, if all options are exercised.

The mobile launcher will support the next generation crew launch vehicle and its associated ground support equipment. It will be used in the assembly, testing and servicing of the vehicle at existing Kennedy facilities. The mobile launcher will transport the rocket to the launch pad and provide ground support for launches.

The mobile launcher consists of the main support structure that comprises the base, tower and facility ground support systems, which include power, communications, conditioned air, water for cooling, wash-down, and ignition over-pressure protection.

Hensel Phelps will supply all labor, materials and equipment necessary for construction of the mobile launcher. Ground support equipment, such as umbilicals, propellant and gases, instrumentation, controls and communications, necessary to support the rocket will be provided and installed under a separate contract or contracts.

The tower of the mobile launcher will have multiple platforms for personnel access and will be approximately 390 feet tall. Construction will take place at the mobile launcher park site area located north of Kennedy's Vehicle Assembly Building at the space center in Florida.

Trestles and girders for a new mobile launcher arrive by barge February 12 at the Launch Complex 39 area turn basin of NASA's Kennedy Space Center.

The new launcher will be lighter than space shuttle mobile launcher platforms so that the crawler-transporter can pick up the added load of the 345-foot tower and taller rocket.

When the structural portion of the new mobile launcher is complete, umbilicals, access arms, communications equipment and command and control equipment will be installed.

Steel workers prepare a live, potted kumquat tree for a "topping out" ceremony to take place when the tenth and final tower section of a new mobile launcher is hoisted onto the tower later this week. In ancient Scandinavian society, the placement of an evergreen tree on a building's ridge pole signaled to all who helped with its construction that the celebration of its completion would begin.
