NASA has awarded a $667.3 million contract to Lockheed Martin Corp. of Gaithersburg, Md., to provide integrated support for the hardware, software, data and displays used to train for and execute human spaceflight missions. The new Facilities Development and Operations Contract, or FDOC, combines work previously performed under two separate contracts, and the synergy is expected to augment the efficiency and effectiveness of the human spaceflight operations team. The FDOC replaces the Mission Support Operations Contract and incorporates portions of the work performed under the Space Program Operations Contract. The contract provides consolidated systems services development and operations support within NASA's Mission Control Center in Houston and backup control centers for the space shuttle, International Space Station and Constellation programs. The FDOC team will ensure the availability, integrity and reliability of space station avionics software, space shuttle and space station integrated planning systems, shuttle and station simulators for crews and flight controllers, and space shuttle flight software production. In addition, it will support development of a Constellation training facility, simulators and mission control systems. The majority of the work for the contract will take place at or near NASA's Johnson Space Center in Houston.
