Flight accommodations using a special structure

A special payload carrier structure has been developed in order to provide Space Shuttle flight accommodations for an exceptionally heavy instrument package requiring no subsystems support. This Mission Peculiar Equipment Support Structure (MPESS) will support the OSTA-2 payload for a materials processing mission. The modular design of the MPESS offers a payload support capability at multiple locations within the Space Shuttle cargo bay. The MPESS is also scheduled for use with earth observation instruments to be carried by the OSTA-3 mission in late 1984.

Mixed mode missions - Designing payloads to match flight opportunities

Shuttle missions have usually been viewed as being devoted to a single mission mode. But full utilization of the STS capabilities as a platform for space research dictates a flexible strategy toward payload integration and mission design. Simple interfaces, single disciplines, and large design and resource margins point the way toward larger payload integration and operation costs. Payloads for early missions (i.e., OSTA-1, OSS-1, and MEA) are used as illustrations to support this argument. The implications of this approach for future NASA plans as well as for new STS operational concepts are considered.
