Manifest - Payloads and accommodations

Developing a long-range manifest begins with the assessment of flight rate capability for the next 6 years. Payloads priorities, launch readiness, and service needs are reviewed and compatible mixed cargo flights are determined and integrated with the dedicated missions to become the manifest. Manifest development must also address Orbiter upgrades to assure that payload-related enhancements meet need dates and that new hardware integration does not adversely affect flight rate capability. A series of Space Shuttle upgrades and new capabilities are in development driven by a continuing effort to improve safety margins, support recognized payload needs, and unique SSF requirements. These enhancements include extended mission duration capability, ASRM development, extended middeck payload support capability, and improved attitude control systems.
