NASA’s Kennedy Space Center awarded a contract to Hensel Phelps of Orlando, FL, for the construction of the Ares I mobile launcher for the Constellation Program. Ares I is the rocket that will transport the Orion crew exploration vehicle, its crew, and cargo to low earth orbit. The contract includes an option for an additional Ares I mobile launcher. It is a firm fixed-price contract with a value of more than $263 million if all options are exercised. The mobile launcher will support the Ares I and the vehicle’s associated ground-support equipment. It will be used in the assembly, testing, and servicing of the Ares I at existing Kennedy facilities. The mobile launcher will transport the Ares I 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.
