Evaluation criteria for commercially oriented materials processing in space proposals

An approach and criteria for evaluating NASA funded experiments and demonstrations which have commercial potential were developed. Methods for insuring quick initial screening of commercial proposals are presented. Recommendations are given for modifying the current evaluation approach. New criteria for evaluating commercially orientated materials processing in space (MPS) proposals are introduced. The process for selection of qualified individuals to evaluate the phases of this approach and criteria is considered and guidelines are set for its implementation.

Buying a Shuttle ticket

A preliminary draft policy for reimbursement for Space Shuttle flights has been developed by NASA in the form of pricing criteria for Space Transportation System (STS) users in domestic and foreign government and industry. The reimbursement policy, the transition from expendable launch vehicles to STS, the new user services, and the interaction of the economics of new user services and STS cost to fly are discussed in the present paper. Current efforts to develop new users are noted.

Systems approach to low cost payload design and operations

It is argued that the numerous factors governing the development and use of low-cost payload systems must be analyzed from a total systems viewpoint covering design, standardization, reuse, and refurbishment operations both in orbit and on the ground. Standardization of payloads for use with different transportation systems is shown to require extensive management studies involving cooperation between users and the technical community. Problems and potential solutions are identified in areas of orbital and ground-based refurbishment, and candidate vehicle systems are discussed for delivery, repair, replacement, and resupply of systems in orbit.

Low cost payload studies

Low cost payload studies aimed at the reduction of Space Shuttle cost, with the emphasis on mission support subsystem equipment, are reviewed. Spacecraft design, manufacturing and operational approaches are specified and quantified to demonstrate the feasibility of reductions of cost from present-day estimates. Space Shuttle design capabilities for retrieval, repair, and reuse of future payloads are indicated as cost reduction possibilities. It is also pointed out that an increased volume and weight carrying capability of the Space Shuttle can alter the design approach to future payloads to reduce cost. Details are given on some specific subsystem component design alterations integrated in an overall low-cost payload design. Refurbishment is discussed as the final area of interest for low cost payload design. Total program savings of up to 50% are found to be possible in the studies.
