COSTS FOR MISSIONS IN SPACE CAN BE REDUCED SIGNIFICANTLY BY UTILIZING LUNAR RESOURCES. CONSIDERING THE GREAT INTEREST IN THE AVAILABILITY OF OXYGEN, WE PROPOSE TO INVESTIGATE ITS ELECTROLYTIC PRODUCTION FROM MOLTEN SALT. THIS PROCESS USES LUNAR SOIL WITH MINIMUM OR NO BENEFICIATION AND DOES NOT PRODUCE ANY WASTE. A METAL ALLOYIS OBTAINED AS A USEFUL BYPRODUCT. THIS APPROACH HAS BEEN SUGGESTED BY E ...

THE SPACE BIOLOGY COMMUNITY HAS A WELL DEFINED NEED FOR IN-FLIGHT CENTRIFUGATION FACILITIES TO PROVIDE BOTH EXPERIMENTAL HYPOGRAVITY STIMULATIONS TO TEST SUBJECTS, AND THE NECESSARY 1 G "CONTROL" ENVIRONMENT FOR COMPARISONS WITHMICRO-G DATA. RECENTLY, RENEWED INTEREST HAS DEVELOPED IN FREE-FLYING SATELLITES LAUNCH FROM EXPENDABLE VEHICLES AND THE DEVELOPMENT OF EXPERIMENTS TO TAKE ADVANTAGE OF SUC ...

THE INNOVATION BEING ADDRESSED IN THIS PROPOSAL IS A NEW ARCHITECTURE FOR ARTIFICIAL INTELLIGENCE SYSTEMS CALLED EAGOL. UNLIKE TYPICAL AI SHELLS, THIS SYSTEM INCORPORATES A STRONG REASONING MODEL DERIVED FROM DETAILED COGNITIVE STUDIES OF DECISION MAKING IN A VARIETY OF ARENAS, INCLUDINGINTERNAL MEDICINE DIAGNOSIS, OPERATIONS OF NUCLEAR POWER PLANTS, AND INTELLIGENCE ANALYSIS. PRINCIPAL FEATURES O ...

CURRENT NASA REQUIREMENTS INCLUDE A NEED FOR ONE METER LONG LOW TEMPERATURE HEAT PIPES CAPABLE OF CARRYING 5 TO 50 W OF POWER WITH EVAPORATOR HEAT FLUXES AS HIGH AS 1 W/IN(2). AXIALLY GROOVED HEAT PIPES ARE UNDESIRABLE FOR SOME APPLICATIONS BECAUSE OF POOR LIFT AND/OR LOW EVAPORATIVE HEAT TRANSFER COEFFICIENT. RECENT ADVANCES IN SINTERED POWDER METAL TECHNOLOGY AT THERMACORE HAVE RESULTED IN SINTE ...

THE NASA TECHNICAL SOLICITATION REQUESTED INNOVATIVE APPLICATIONS OF NEW MATERIALS FOR USE IN HEAT TRANSPORT AND COOLING. THIS PROPOSAL DESCRIBES AN EFFORT TO DEMONSTRATE THE FEASIBILITY OF USING COMPOSITE MATERIALS IN THE CONSTRUCTION OF AMBIENT TEMPERATURE HEAT PIPES. CARBON COMPOSITE MATERIALS ARE RECOGNIZED FOR THEIR SIGNIFICANT STRENGTH TO WEIGHT RATIO AND STIFFNESS. THE SUCCESSFUL DEVELOPMEN ...

A SIX MONTH PROGRAM TO DEVELOP A RUGGED NEW DEVICE FOR MONITORING THE ONSET OF ICE FORMATION ON SURFACES OF TRANSPORTATION VEHICLES, ROADS, BRIDGES AND AIRCRAFTS, WILL BE DEVELOPED AND A PROTOTYPE WILL BE LABORATORY TESTED. THE NOVEL GAGE AND ELECTRONIC SYSTEM IS PARTLY BASED ON THE TECHNOLOGY APPLIED TO MEASURE CONDUCTIVITY OF SOLUTIONS. BASED ON EXISTING TECHNOLOGY, AND ALREADY TESTED UNDER HIGH ...

METAL MATRIX COMPOSITES (MMC) APPEAR VERY PROMISING FOR USE IN THERMALLY STABLE SATELLITE STRUCTURES. HIGH SPECIFIC MODULI AND LOW THERMAL EXPANSION APPEAR TO MAKE THESE MATERIALS IDEAL FOR SATELLITE APPLICATION. EXTREME THERMAL STABILITY REQUIREMENTS FOR SATELLITE SENSOR MOUNTING STRUCTURE REQUIRES THAT THE DESIGN OF SUCH STRUCTURE USING MMC TAKE INTO ACCOUNT THE NONLINEAR THERMOMECHANICAL RESPON ...
