RELEASE: 94-011 January 28, 1994


Flight control for STS-60, the 18th voyage of Discovery, will follow the procedures and traditions common to U.S. manned space flights since 1965, when the Mission Control Center was first used.

Responsibility for conducting Shuttle operations will revert to the Mission Control Center (MCC) in Houston once Discovery's two solid rocket boosters ignite. Mission support in the MCC will begin five hours prior to lauch and continue through landing.

The primary payloads of STS-60 are the Spacehab module, making its second Shuttle flight, and the Wake Shield Facility, making its first Shuttle flight. The Wake Shield Facilityis planned to be released and fly free from Discovery for about 54 hours before it is retrieved and placed back in the cargo bay for the return to earth. Also in Discovery's payload bay will be an assortment of secondary experiments housed in Get-Away Special canisters, including a set of six metal spheres that will be deployed from Discovery near hte end of the mission as part of the Orbital Debris Radar Calibration Spheres (ODERACS) experiment. In addition, a satellite built by the University of Breman, called BREMSAT, will be deployed.

Orbiter operations will be conducted from Flight Control Room One (FCR-1) on the second floor of the MCC, located in Bldg. 30 at the Johnson Space Center. Standard voice communications between the orbiter and the MCC will employ the call signs "Houston" and "Discovery." A team of about 300 flight controllers, technicians, analysts and support personnel will alternate shifts in the control center and in nearby facilities. The handover between each team takes about an hour and allows each flight controller to brief his or her replacement on developments during hte previous two shifts.

The flight control teams for the mission will be referred to as the Ascent/Entry, Orbit 1, Orbit 2 and Orbit 3 teams. The Ascent and Entry teams will be led by Flight Director Jeff Bantle. The Orbit 1 Shift will be conducted by Flight Director Al Pennington. The Orbit 2 team will be directed by STS-60 lead Flight Director Chuck Shaw. Thei Orbit 3 Team will be led by Flight Director Bob Castle.



The flight control positions in the MCC, and their responsibilities, are:

Flight Director (FLIGHT)

Has overall responsibility for the conduct of the mission.

Spacecraft Communicator (CAPCOM)

By tradition an astronaut; responible for all voice contact with the flight crew.

Flight Activities Officer (FAO)

Responsible for procedures and crew timelines; provides expertise on flight documentation and checklists; prepares messages and maintains all teleprinter and/or Text and Graphic System traffic to the vehicle.

Intergrated Communications Officer (INCO)

Responsible for all Orbiter data, voice and video communications systems; monitors the telemetry link between the vehicle and the ground; oversees the uplink command and control processes.

Flight Dynamics Officer (FDO)

Responsible for monitoring vehicle performance during the powered flight phase and assessing abort modes: calculating orbital maneuvers and resulting trajectories; and monitoring vehicle flight profile and energy levels during reentry.

Trajectory Officer (TRAJECTORY)

Also known as "TRAJ," this operator aids the FDO during dynamic flight phases and is responsible for maintaining the trajectory processors in the MCC and for trajectory inputs made to the Mission Operations Computer.

Guidance, Navigation & Control Systems Engineer (GNC)

Responsible for all inertial navigational systems hardware such as star trakers, radar altimeters and the inertial measurement units; monitors radio navigation and digital autopilot hardware systems.

Guidance & Procedures Officer (GPO)

Responsible for the onboard navigation software and for maintenance of the Orbiter's navigation state, known as the stat vector. Also responsible for monitoring crew vehicle control during ascent, entry, or rendezvous.



Rendezvous Guidance and Procedures Officer (RENDEZVOUS)

The RENDEZVOUS GPO is specialist who monitors onboard navigation of the Orbiter during the rendezvous and proximity operations.

Environmental Engineer & Consumables Manager (EECOM)

Responsible for all life support systems, cabin pressure, thermal control and supply and waste water management; manages consumables such as oxygen and hydrogen.

Electrical Generation and Illumination Officer (EGIL)

Responsible for power management, fuel cell operation, vehicle lighting and the master caution and warning system.

Payload Officer (PAYLOADS)

Coordinates all payload activities; serves as principal interface with remote payload operations facilities.

Data Processing Systems Engineer (DPS)

Responsible for all onboard mass memory adn data processing hardware; monitors primary and backup flight software systems; manages operating routines and multi-computer configurations.

Propulsion Engineer (PROP)

Manages the reaction control and orbital maneuvering thrustes during all phases of flight; monitors fuel usage and storage tank status; calculates optimal sequences for thruster firings.

Booster System Engineer (BOOSTER)

Monitors main engine and solid rocket booster performance during ascent phase.

Ground Controller (GC)

Coordinates operation of ground stations and other elements of worldwide space tracking and data network; responsible for MCC computer support and displays.



Maintenance, Mechanical, Arm & Crew Systems (MMACS)

Formerly known as RMU; responsible for remote manipulator systme; monitors auxilliary power unitsss and hydraulic systems; manages payload bay and vent door operations.

Extravehicular Activities (EVA)

A specialist responsible for monitoring and coordinating preparations for and execution of space walks. Responsibilities include monitoring suit and EVA hardware performance.

Payload Deployment & Retrieval Systems (PDRS)

A specialist responsible for monitoring and coordinating the operation of the remote manipulator system.

Flight Surgeon (SURGEON)

Monitors health of flignt crew; provides procedures and guidance on all health-related matters.

Public Affairs Officer (PAO)

Provides real-time explanation of mission events during all phases of flight.
