Materials science and engineering in space

Abstract

The influences of gravitational forces on processes used in the preparation of materials employed in earth-based applications are addressed and the benefits which may be derived from the microgravity environment of space in improving on such constraints are considered. Attention is given to the fact that Materials Processing in Space is directed toward the utilization of the unique space environment as a tool to establish a scientific characterization of materials processes for technological exploitation in the public benefit. In the context of enhancement to earth-based technology or implementation of space-based processes for specialized, low volume, high value materials, the thrust of the Materials Processing in Space program is surveyed.
