Opportunities for commercial participation in microgravity material processing

The existing facilities and procedures for materials processing in space are described. The role of NASA and the government in stimulating the commercialization of space are discussed. The physics of the different experiments is studied in order to identify the relationship between power and time. A list of the physical and engineering requirements for proposed materials processing payloads is presented. The use of the Space Shuttle and Space Station for materials processing experiments and the development of techniques to realize the full potential of the Shuttle and Station capabilities are examined. NASA provides drop tube and drop tower facilities for research on materials and low gravity materials experiments are being conducted using aircraft in parabolic flight. The applications of the Materials Experiment Assembly, the Spacelab module, the Shuttle middeck, and Get-Away Special for materials processing are considered.

Opportunities for commercial organizations

The possible applications of technology of materials processing in low gravity is discussed. A special office established by NASA to familiarize commercial organizations with materials processing in low gravity is described. This office provides information on present research and will, if requested, hold a seminar to present the technological and business aspects of joint investigations and joint endeavors to interested organizations. Arrangements can be made for visits to laboratories where ground based research is in progress.

Materials Experiment Carrier - An approach to expanded space processing capability

Conceptual design studies and mission analyses within the NASA Materials Processing in Space (MPS) program of the Materials Experiment Carrier (MEC) approach to conducting near-term as well as future free-flying experiments in materials processing in space are discussed. The experimental background of the MPS program is reviewed, and it is pointed out that the use of the MEC coupled with the 25-kW power system can provide an order-of-magnitude cost savings over conventional Shuttle-based systems, as well as increased orbital stay time and microgravity stability. The determination of the physical and engineering requirements for future MEC scientific/commercial candidate payloads is then discussed, and two proposed candidates for the MEC configuration, which is intended to be a self-contained, general-purpose, versatile and reusable carrier, are illustrated. Possible MEC operations are considered, including mission profiles, deployment sequences, on-orbit payload/sample change-out, optimal power system utilization, the use of real-time, ground-based control and advanced automatic payload operation. Areas in which technology development could benefit the MEC project are also identified.

Space processing payload experiment requirements

An overview is given of the definition of research requirements and derivation of engineering design requirements for a group of 77 representative applications of space processing. Representative requirements are documented for applied research in space on biological processes, chemical/fluid phenomena, solidification processes, and glass/ceramics processes. Design requirements for payload equipment to accommodate these research requirements are presented in engineering terms, such as power requirements, schematic diagrams, etc. In addition, a summary of the 77 applied research topics is included.

Space processing in early Shuttle missions

The paper first reviews potential scientific and commercial benefits of space processing, and discusses roles of ground laboratory, sounding rocket, and Shuttle/Spacelab experimentation in carrying out space processing programs. Benefits which have been identified in such processes as containerless melting/solidification, electrophoresis, crystal growing, etc., and using such specific materials as tungsten, isoenzymes, single crystal silicon ribbon are utilized as specific examples in the above discussion. As a result, the paper identifies spectrum of specific objectives and implementation approaches for Shuttle/Spacelab experimentation. The paper then reviews currently planned Shuttle/Spacelab payload accommodations and traffic model. Finally, the paper matches experimentation approaches with Shuttle/Spacelab plans, and derives a possible schedule of missions in the 1979-1982 time frame using configurations with a high degree of automation where crew time for experiment involvement is limited.

The integration of commercial payloads into Spacelab

Results of a three-year study for identification of beneficial uses of space are used to project potential problems in integrating commercial payloads into Spacelab. Specific examples from this NASA-funded study are given to illustrate these problems, and to suggest some potential approaches for arriving at solutions.

Requirements and concepts for space-processing payloads

The definition of facilities which will serve the research needs of a large group of users is given. These facilities (payloads) are derived by several combinations of items from a large inventory of modular, reusable, research equipment which enables ready response to many flight opportunities. Workable concepts were prepared and submitted to the Spacelab design activity. These designs permit the flying of either partial or dedicated payloads. The technical integrity of the modular approach to payload design/integration and the utility of commercial equipment technology are also discussed.
