Projected future space processing activities

A brief review is presented on where the space processing program stands with respect to its long range objectives and what plans have been made to pursue them in the next several years. These objectives are to make a permanent place for space processing as an integral part of the world's materials technology, and from this broad viewpoint there are two things that are clearly necessary to reach the program's goal. One of them is a space flight system large enough to support materials research and development work on a significant scale and eventually support manufacturing operations as well if these develop. The other is a group of materials scientists and engineers large enough to do space research and development on a scale that can impact materials science and technology and eventually develop manufacturing as well as research applications of space processing.

Projection for Space Geodynamics, 1988-1998

Premises defining the technical and operational environment of the next decade are listed. Observational programs required to satisfy scientific objectives in the study of geopotential fields, global dynamics, tectonics, and regional tectonics/crustal hazards are defined. Capabilities and applications of the Geopotential Research Mission to be launched in the early 1990's are explored and the benefits of more detailed measurements of the Moon and planets are indicated. Earthquake prediction in the western part of the U.S. is discussed. The use of decimeter, centimeter, and millimeter systems for very long baseline interferometry, satellite laser ranging, and lunar ranging techniques are discussed. Geographic regions of particular interest are identified.

Space Station Food System

A team of engineers and food scientists from NASA, the aerospace industry, food companies, and academia are defining the Space Station Food System. The team identified the system requirements based on an analysis of past and current space food systems, food systems from isolated environment communities that resemble Space Station, and the projected Space Station parameters. The team is resolving conflicts among requirements through the use of trade-off analyses. The requirements will give rise to a set of specifications which, in turn, will be used to produce concepts. Concept verification will include testing of prototypes, both in 1-g and microgravity. The end-item specification provides an overall guide for assembling a functional food system for Space Station.

Mars Lander/Rover vehicle development: An advanced space design project for USRA and NASA/OAST

A design is proposed for a Mars Lander/Rover (MLR) for use in gathering needed environmental and surface information. The design focus will be upon a Mars Lander/Rover that will leave an orbit around Mars, reenter and soft land on the Martian surface, and move sequentially to widely scattered locations to sample, measure, and analyze the Martian environmental and surface conditions. Primary goals will be payload mass and size definition, characterization of the Martian atmosphere, selection of sampling locations, identification of alternative design concepts, selection of a preferred design, team organization, and preparation for the detailed design phase.

Mars Lander/Rover vehicle development: An advanced space design project for USRA and NASA/OAST

The results of the studies on one particular part of the Mars Lander/Rover (MLR) system are contained: the Balloon Rover. This component vehicle was selected for further research and design because of the lack of technical literature on this subject, as compared to surface rover technology. Landing site selection; balloon system development and deployment; optics and communications; and the payload power supply are described.

[Earth and Space Sciences Project Services for NASA HPCC]

This grant supported the effort to characterize the problem domain of the Earth Science Technology Office's Computational Technologies Project, to engage the Beowulf Cluster Computing Community as well as the High Performance Computing Research Community so that we can predict the applicability of said technologies to the scientific community represented by the CT project and formulate long term strategies to provide the computational resources necessary to attain the anticipated scientific objectives of the CT project. Specifically, the goal of the evaluation effort is to use the information gathered over the course of the Round-3 investigations to quantify the trends in scientific expectations, the algorithmic requirements and capabilities of high-performance computers to satisfy this anticipated need.
