RELEASE: 94-070


Flight control for STS-66, the thirteenth flight of Atlantis, will follow the procedures and traditions common to U.S. manned space flights since 1965, when the Mission Control Center (MCC) was first used.

The responsibility for Shuttle operations will revert to the MCC, Houston, once Atlantis' two solid rocket boosters ignite. Mission support in the MCC will begin five hours prior to launch and continue through landing.

The primary objectives of STS-66 are the around-the-clock operation of the third Atmospheric Laboratory for Applications and Sciences (ATLAS-3) and the deployment and retrieval of the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-Shuttle Pallet Satellite (CRISTA-SPAS).

The Space Shuttle operations will be conducted from Flight Control Room One on the second floor of the MCC, located in Bldg. 30 at the Johnson Space Center. Voice communications with Atlantis will be as standard from the MCC using the call signs "Houston" and "Atlantis" while ATLAS-3 operations will be controlled from the Payload Operations Control Center at the Marshall Space Flight Center, Huntsville, Ala., using the call signs "Huntsville" and "ATLAS."

The teams of MCC flight controllers will alternate shifts in the control center and in nearby analysis and support facilities. The handover between each team takes about an hour, allowing each controller to brief their replacement on developments during the previous two shifts.

The MCC flight control teams for this mission will be referred to as the Ascent/Entry Team, the Orbit 1 Team, Orbit 2 Team, Orbit 3 Team and Team 4. The Ascent/Entry Team will be led by Flight Director Jeff Bantle. The Orbit 1 Team will be led by Lead STS-66 Flight Director Bob Castle. The Orbit 2 shift will be conducted by Flight Director Milt Heflin. The Orbit 3 Team will be led by Flight Director Phil Engelauf. Team 4, led by Flight Director Wayne Hale, will work various shifts to offer other teams a day off.

Integrated 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 trackers, 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 state vector. Also responsible for monitoring crew vehicle control during ascent, entry, or rendezvous.

Rendezvous Guidance and Procedures Officer (RENDEZVOUS)

The RENDEZVOUS GPO is a specialist who monitors onboard navigation of the Orbiter during 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.

Payloads 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 and 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 thrusters during all phases of flight; monitors fuel usage and storage tank status; calculates optimal sequences for thruster firings.

Booster Systems 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)

Monitors auxiliary power units and hydraulic systems; manages payload bay and vent door operations; handles in-flight maintenance planning; oversees orbiter structure, tiles, blankets, etc.

Extravehicular Activities (EVA)
