Mission Operations Support Building (MOSB) is located at entrance of PHSF complex. The onestory steel building has an insulated metal siding exterior. It is 2,209 sq. ft and consists of several office areas with cubicles available. Also, there are three conference rooms, which seat 30, 20, and 46 people. On the south end of the building there are two payload control rooms and are separated by a rollup door. These rooms serve as a ground station for checkout and testing of the customer’s spacecraft located in the service bay. There is a Propellant Handlers Ensemble (PHE) change room on the northwest side of the building which is only accessible from the outside. This room contains lockers and the necessary equipment for PHE operation change. Room 148 is MIL-71 Ground Station which serves as the testing area for the spacecraft’s telemetry system. The room contains all of the electrical power interfaces and communication interfaces to support Electrical Ground Support Equipment (EGSE). The EGSE is deployed for the spacecraft testing phase prior to launch. The room contains desks and phones for approximately three to four testing personnel. Control rooms in the MOSB can be used to monitor activities in the PHSF.
The airlock has a 15-ton (13.6 t) bridge crane that operates on twin runway girder rails in an eastwest direction. The effective east-west travel of the hoist (hook centerline to wall) is to a point 17 ft, 5 in (5.3 m) from the east wall, and 12 ft, 11 in (3.9 m) from the west wall. The effective northsouth travel of the hoist (hook centerline to wall) is 4 f, 9.5 in (1.5 m) from the north wall and 4 ft, 5 in (1.3 m) from the south wall. The maximum hook height is 72.5 ft (22.1 m). The service bay has two 50-ton (45.4 t) bridge cranes that operate on twin runway girder rails in an east-west direction. The nominal hook height for each of the cranes is 74.5 ft (24.3 m). Both crane hooks are outfitted with a debris shield to protect payloads from any possible overhead debris falling from the crane. The effective east-west travel of the west crane hoist (hook centerline to wall) is to a point 31 ft, 5 in (9.5 m) from the east wall, and 13 ft, 9 in (4.2 m) from the west wall. The effective north-south travel of the hoist (hook centerline to wall) is 6 ft, 5 in (2 m) from the north and south walls. The effective east-west travel of the east crane hoist (hook centerline to wall) is a point 11 ft, 2 in (3.4 m) from the east wall, and 34 ft, 3 in (10.4 m) from the west wall. The effective north-south travel of the hoist (hook centerline to wall) is 11 ft (3.3 m) from the north wall and 9 ft, 10 in (2.9 m) from the south wall. CCTV provides closed-circuit video surveillance of payload processing from operational areas (PHSF Rooms 116 and 117) to control and monitor areas in the payload control rooms and in the facility control room in the MOSB. Also, four monitors are located in the PHSF security room 110. There are eight pan-and-tilt CCTV cameras. Four are in the PHSF and two each (one portable and one fixed) are in the fuel transfer building and oxidizer shed. These cameras and pan-and-tilt units are hazard-proof.
Sliding doors on the east and west sides allow payload access to the facility high bay. When the facility is used for payload processing, 30 to 40 people occupy the building during operations and work from temporary offices inside the MOSB.
