ATTACHMENT 05: DEFINITIONS

Anomaly: An unexpected event that can reasonably be considered to pose immediate mission success implications for subsequent NASA missions. An anomaly requires an engineering evaluation and Engineering Review Board disposition prior to a NASA mission on an affected logistics vehicle or launch vehicle configuration.

Approach Initiation: AI is the first maneuver during a nominal approach that is targeted to bring the vehicle inside the Rendezvous Sphere.

Authority to Proceed: Notification from the Contracting Officer to proceed with work on a

Gateway Logistics Task Order (GLTO).

Cargo: Cargo, Orbital Replacement Units (ORUs), and/or payloads including packing materials, attachment hardware and/or Flight Support Equipment.

Common GLS Configuration: A distinct combination of the common launch vehicle configuration, including final stages (exclusively used for orbit circularization or escape) and trim stages, and a logistics vehicle.

Common GLS Configuration Changes: A common launch vehicle configuration change or logistics vehicle items that substantially affect structural integrity, operating life, total impulse and/or thrust profile of the final stage and/or trim stage, Gateway interface(s), or Gateway interoperability are considered changes to the common GLS logistics configuration. Examples of logistics configuration changes include major structural changes resulting in significant increase/decrease in logistics vehicle mass or volume affecting Gateway controllability or docking systems.

Common GLS Configuration Upgrades or Modifications: Common launch vehicle configuration upgrades or modifications or logistics vehicle items that do not substantially affect structural integrity, operating life, total impulse and/or thrust profile of the final stage and/or trim stage, Gateway interface(s), or Gateway interoperability are considered upgrades or modifications to the common GLS configuration. Examples of upgrades and modifications include changes in software, electrical/mechanical interfaces, and incorporation of mission-unique requirements. Upgrades or modifications are not to be interpreted as common GLS configuration changes.

Common Launch Vehicle Configuration: A distinct combination of core propulsive stages and hardware used to deliver payloads to earth orbit or escape trajectories.

Common Launch Vehicle Configuration Changes: Items that substantially affect the airframe integrity, operating time, total impulse and/or thrust profile of one or more core propulsive stages are considered changes to the common launch vehicle configuration. Examples of vehicle configuration changes include the replacement of engine types, core propulsive stages, and/or major airframe structures.

Common Launch Vehicle Configuration Upgrades or Modifications: Items that do not substantially affect operating time, total impulse, and/or the thrust profile of one or more propulsive stages are considered upgrades or modifications to the common launch vehicle configuration. Examples of upgrades and modifications include changes in software, payload fairing, payload electrical/mechanical interfaces, incorporation of mission-unique requirements, and the addition or deletion of a final stage (exclusively used for orbit circularization or escape), strap-on motors, and/or trim stage. Upgrades or modifications are not to be interpreted as common launch vehicle configuration changes.

Core Propulsive Stages: All propulsive stages except strap-on motors, final stages (exclusively used for orbit circularization or escape), and trim stages.

Discrepant: Visibly damaged or out of configuration.

Element Adapter: The structural interface, including electrical connectors, between the delivery vehicle and the element to be delivered.

Emergency Equipment and Systems: A set of components (hardware and/or software) used to mitigate or control hazards, after occurrence, which present an immediate threat to the crew or crewed spacecraft. Examples include fire suppression systems and extinguishers, emergency breathing devices, and crew escape systems.

Emulator: The emulator is a “Gateway in a Box” that provides the most current hardware and simulated operational inputs/outputs, including software interfaces, for the Gateway side of the

Gateway/Logistics Vehicle interface.

Fast Transit to Gateway: End-to-end cargo delivery service that requires docking 30 days or less from the time of launch.

Flight Support Equipment: Contractor provided hardware required to secure and integrate cargo to the logistics vehicle (internal or external).

Integrated Operations (with Gateway): All operations starting at 90 minutes prior to AI and lasting until the vehicle leaves the Gateway Rendezvous Sphere on a non-return trajectory.

Intentional Ignition: Start of the ignition process of the Launch Vehicle for the purpose of

Launch, which is the time at which the command signal is sent to the Launch Vehicle.

Launch: The intentional ignition of the first-stage motor(s) of the launch vehicle that has been integrated with the payload.

Logistics Element: The collection of systems, capabilities, organizations, and contracts that provides the Gateway Logistics function. Includes NASA, contractors, and international partners, as necessary.

Logistics Vehicle: A carrier spacecraft used to deliver cargo and payloads to Gateway as a visiting vehicle.

Logistics Module: the Logistics Vehicle configuration with pressurized and/or unpressurized payloads that becomes a docked and integrated part of the Gateway system.

Mission Control Center-Houston Mission Authority: MCC-H has authority to make final decisions regarding LM operations, including but not limited to GO/NO GO decisions and the safety of flight and crew(s). This authority begins with either Gateway Integrated Operations, or 30 minutes before the first required Gateway configuration or crew activity in support of the LM during rendezvous (e.g., Gateway attitude maneuver, appendage configuration, USOS GPS configuration), whichever comes first; it ends with either the end of Gateway Integrated Operations or when Gateway is no longer required to maintain its configuration to support the LM, whichever comes later. This authority applies any time the LM free-drift trajectory, including dispersions, is predicted to enter the Gateway Rendezvous Sphere within the next 24 hours.

Mission Specific: All standard, mission unique and first flight services provided to meet the requirements of a Specialized GLS Missions.

Non-NASA Cargo: Any cargo on a GLS mission that is not NASA cargo will be considered non-

NASA cargo in accordance SOW Section 2.2.26, Contractor Objectives on Gateway Logistics

Service (GLS) Missions

Party or Parties: The Contractor or NASA, or both.

Real-time: Period of time during which integrated operations are taking place.

Rendezvous: The phase of the mission from orbit insertion to the proximity (the point at which

AI maneuver occurs) of the Gateway.

Rendezvous Sphere: The 10-kilometer radius sphere around the Gateway center of mass, used to govern the Rendezvous Orbit Entry decision.

Team Members: Consist of two or more companies that form a partnership or joint venture to act as a potential prime contractor; or a potential prime contractor agrees with one or more, other companies to have them act as its subcontractors under a specified Government contract or acquisition program.

Third Party: Any person or entity other than NASA, the Contractor, and related parties.
