NNX11CB28C - BEAR ENGINEERING PROPOSES TO ADVANCE THE DEVELOPMENT OF AN INNOVATIVE HIGH TORQUE, LOW SPEED, DIRECT DRIVE MOTOR IN ORDER TO MEET NASA'S REQUIREMENTS FOR SUCH DEVICES. FUNDAMENTALLY, ALL ELECTRIC MOTORS BASICALLY WORK ON THE SAME ELECTROMAGNETIC PRINCIPLE: A TANGENTIAL ELECTROMAGNETIC FORCE ATTRACTS THE ROTOR TO THE STATOR. JUST WHEN THE ROTOR FIELD IS CLOSEST TO THE STATOR FIELD AND THE ELECTROMAGNETIC ATTRACTION IS GREATEST, THE POWER IS INTERRUPTED AND ANOTHER SET OF MAGNETIC POLES REPEATS THE CYCLE. FURTHERMORE, THE TWO MAGNETICALLY ATTRACTED ELEMENTS NEVER MAKE CONTACT, WHICH WOULD OTHERWISE OFFER THE HIGHEST FORCE OF ATTRACTION. THE PROPOSED NOVEL MOTOR DESIGN, SUCCESSFULLY DEMONSTRATED AT TRL 4 IN PHASE 1, OPERATES AND BEHAVES ENTIRELY DIFFERENTLY FROM ALL OTHER KNOWN ELECTRIC MOTOR DESIGNS AND IS CAPABLE OF PRODUCING INCREDIBLY HIGH, DIRECT DRIVE TORQUES AT LOW ROTATIONAL SPEEDS. ITS OPERATIONAL PERFORMANCE IS SIMILAR TO THAT OF A STEPPER MOTOR WITH A 1000:1 GEARHEAD ATTACHED, BUT THE SIMILARITY ENDS THERE. THE MOTOR IS CONFIGURED SUCH THAT ITS LENGTH TO DIAMETER ASPECT RATIO IS OPPOSITE THAT OF TRADITIONAL MOTORS AS IT HAS A RELATIVELY LARGE DIAMETER AND SHORT AXIAL LENGTH; THIS OFFERS ALL NEW PACKAGING OPPORTUNITIES. THE DESIGN ALSO ALLOWS FOR A SINGLE, LARGE DIAMETER BEARING PAIR TO BE USED FOR THE MOTOR'S OUTPUT SHAFT WHICH RENDERS IT STIFF ENOUGH TO DIRECTLY MOUNT THE DRIVEN ELEMENTS. THE NEED FOR ADDITIONAL BEARING SUPPORTS AND BEARING MOUNTING STRUCTURE IS THUS ELIMINATED. BY THE END OF PHASE 2, THE SYSTEM WILL BE DESIGNED, DEVELOPED AND TESTED AT TRL 6 WITH MARS ENVIRONMENTAL CONDITIONS.

NNX11CF31P - NASA HAS DEVELOPED SPACE-BASED THERMAL INSTRUMENT SPECTROMETERS BASED ON THERMOPILE DETECTORS LINEAR ARRAYS THAT ARE INTRINSICALLY RADIATION HARD. MICRO-BOLOMETERS ARE KNOWN TO OFFER VERY HIGH SENSITIVITY DUE TO HIGH THERMAL ISOLATION AND LOW THERMAL MASS HOWEVER ARE AT PRESENT INFERIOR TO THERMOPILES FOR SPACE-BASED SPECTROMETERS. IN ORDER TO ACHIEVE HIGH PERFORMANCE IN LINEAR ARRAY SPECTROMETER APPLICATIONS, BOLOMETERS NEED IMPROVEMENT IN THREE AREAS: REDUCED 1/F NOISE, STABLE PERFORMANCE OVER A WIDE SYSTEM TEMPERATURE RANGE, AND IMPROVED RADIATION HARDNESS. BLACK FOREST ENGINEERING ON PHASE I WILL DESIGN BOLOMETER AND READOUT CIRCUITRY FOR LINEAR ARRAY SPECTROMETER APPLICATIONS REQUIRING HIGH PERFORMANCE IN A RADIATION ENVIRONMENT WHILE ALSO ADDRESSING SIGNAL STABILITY/CALIBRATION AND OTHER MISSION REQUIREMENTS. THE PREDICTED PERFORMANCE WILL BE COMPARED TO THERMOPILE ARRAYS AND RECOMMENDATIONS MADE FOR A PHASE II DEMONSTRATION IN ONE OR MORE BANDS OF THE JEO THERMAL INSTRUMENT OR OTHER NASA SPECTROMETER APPLICATIONS. THE BOLOMETER SPECTROMETER ARCHITECTURE WILL ALSO OFFER MONOLITHIC CONSTRUCTION ON 200 MM DIAMETER SILICON WAFERS AND REDUCED CROSS-SCAN PITCH IF DESIRED TO SUPPORT HIGHER SPATIAL RESOLUTION AND WIDER FOV APPLICATIONS.

NNX10CE13P - THE MARS SAMPLE RETURN MISSION IS BEING PLANNED TO RETURN SAMPLES OF MARTIAN ROCK, REGOLITH, AND ATMOSPHERE TO EARTH FOR SCIENTIFIC ANALYSIS. THE MARTIAN SAMPLE SIZE IS DIRECTLY AFFECTED BY THE PROPULSION CAPABILITIES OF THE MARS ASCENT VEHICLE (MAV) AND INNOVATIONS ARE SOUGHT TO ENHANCE PROPULSION CAPABILITIES OF THE MAV FOR FUNCTIONS INCLUDING PRIMARY PROPULSION FROM THE MARS SURFACE, ORBIT INSERTION, AND ATTITUDE CONTROL. THE PROPOSED CONSTANT-VOLUME COMBUSTION ROCKET (CVC) PROPULSION TECHNOLOGY WILL LEAD TO 1) SIGNIFICANT WEIGHT REDUCTION AND SIMPLIFICATION; 2) REDUCED COSTS IN THE SYSTEM COMPONENTS AND GROUND SERVICING; 3) PROLONGED MISSION OR SYSTEMS LIFETIMES; 4) IMPROVED RELIABILITY; AND 5) ENHANCED CRITICAL MISSION FUNCTIONS. THE CONSTANT VOLUME COMBUSTION (CVC) ENGINE IS AN INNOVATIVE DESIGN THAT COMBINES LIGHT WEIGHT, LOW PRESSURE FUEL TANKS AND OPERATES AT HIGH CHAMBER PRESSURES. THE CVC ENGINE HAS NEARLY IDENTICAL SPECIFIC IMPULSE AS THE CONSTANT PRESSURE ENGINE WITH THE SAME MASS FLOW AND THROAT AREA, FURTHERMORE, THE NOZZLE OPTIMIZES AT THE SAME AREA RATIO. IT HAS EXCEPTIONAL THRUST-TO-WEIGHT RATIOS, AND THE PROPOSED BIPROPELLANT SYSTEM MEETS MARTIAN TEMPERATURE REQUIREMENTS WITHOUT HEATING OR STIRRING. DURING PHASE 1 WE WILL DEMONSTRATE, THROUGH ANALYSIS, EXPERIMENTATION, AND HOT-FIRE TESTING, THE FEASIBILITY OF OUR PROPOSED CVC ENGINE AS A CREDIBLE CANDIDATE FOR MARS ASCENT PROPULSION. IN PHASE II, THERE WILL BE AN AGGRESSIVE PUSH TOWARDS FLIGHT-LIKE HARDWARE TO ENSURE RAPID MATURATION OF THE TECHNOLOGY IN ORDER TO MEET THE NASA MISSION GOALS.

NNX10CE16P - BEAR ENGINEERING PROPOSES TO DEVELOP A SIMPLE, ROBUST, EXTREME ENVIRONMENT COMPATIBLE, MECHANICAL LOAD CELL TO ENABLE THE CONTROL OF CONTACT FORCES FOR PLACEMENT OF SAMPLING SYSTEMS AND INSTRUMENTS AGAINST TARGET LOCATIONS. THE LOAD CELL WILL BE USED TO PROVIDE PRESET PRELOADS AND DYNAMICALLY CONTROL THE REACTION FORCE TO A PLATFORM UPON WHICH A SAMPLING SYSTEM OR INSTRUMENT IS MOUNTED. THE NOVEL DEVICE HAS BEEN DESIGNED TO WORK SOLELY BY MECHANICAL MEANS USING SPRING PRELOADED ELECTRICAL CONTACTS TO CREATE 6, 9, 12 OR 18 DISCRETE LOAD SENSING LEVELS, DEPENDING ON DESIGN PARAMETERS. WHEN ANY OF THE LOAD THRESHOLDS HAS BEEN REACHED, THE CORRESPONDING ELECTRICAL CONTACT CHANGES STATE FROM NORMALLY OPEN OR NORMALLY CLOSED. THE LOAD CELL IS COMPLETELY SEALED AND HAS SIMILAR SIZE, SHAPE AND STRAIN DISPLACEMENTS AS TRADITIONAL STRAIN GAGE LOAD CELLS. IT IS EXPECTED THAT THIS NEW DESIGN WILL HAVE A DIAMETER RANGING FROM 2 TO 3 INCHES (DEPENDING ON DESIGNED FORCE LEVEL) AND A THICKNESS OF ABOUT A TO 1 INCH. STRAIN DISPLACEMENT AT FULL LOAD IS EXPECTED TO BE ABOUT 0.003 INCH. FOR FUTURE MARS, VENUSIAN OR OTHER PLANETARY SAMPLING MISSIONS, THE ROBUST LOAD CELL WOULD BE A KEY COMPONENT IN ENSURING AND MAINTAINING PROPER CONTACT WITH ROCKS OR SAMPLES OF INTEREST AND IT WILL BE DEVELOPED TO TRL 4 AT THE END OF THE PROPOSED EFFORT. A POTENTIAL PHASE 2 WILL ADVANCE THE DESIGN TO TRL 6.

NNX09CA88C - FLASH 3D PLANETARY ENTRY, DESCENT AND LANDING SENSOR HARDENING ADVANCED SCIENTIFIC CONCEPTS INC. (ASC) IS A SMALL BUSINESS THAT HAS DEVELOPED A NUMBER OF 3D FLASH LADAR SYSTEMS. FLASH LADAR VIDEO CAMERAS ARE 3D VIDEO CAMERAS THAT RETURN RANGE AND INTENSITY INFORMATION FOR EACH PIXEL IN REAL TIME, AND IS FUNCTIONALLY EQUIVALENT TO 16000 RANGE FINDERS ON ONE CHIP. ACTUAL DATA COLLECTED, AT THE JPL MARS YARD, USING ASC'S COMPACT FLASH LADAR SYSTEM DEMONSTRATED IN A PREVIOUS NASA PHASE I SBIR EFFORT CONFIRM THAT THE ASC FLASH LADAR VIDEO CAMERA (FLVC) SYSTEM CAN MEET THE REQUIREMENTS FOR ENTRY, DESCENT AND LANDING (EDL). THE FLVC'S SMALL SIZE, LOW POWER AND VERY FAST RANGE DATA FRAME RATE (30HZ) THE SENSOR CAN BE CONFIGURED FOR A VARIETY OF EDL MISSIONS. AN EXISTING PHASE TWO EFFORT IS FABRICATING A COMPACT FLVC FOR DELIVERY TO NASA FOR FIELD TESTING, HOWEVER THE SYSTEM IS NOT HARDENED. THE PROPOSED PHASE 2 EFFORT WILL PRODUCE A SPACE QUALIFIED SENSOR ENGINE WHICH CAN BE INTEGRATED WITH THE SYSTEM BEING DELIVERED TO NASA. THE SENSOR ENGINE IS THE BREAK-THOUGH ENABLING TECHNOLOGY FOR THE FLVC. THE SENSOR ENGINE WILL BE FABRICATED, TESTED AND USED TO UPGRADE THE CAMERA JPL. AS A RESULT OF THESE IMPROVEMENTS, THE TRL LEVEL OF THIS SENSOR WILL BE AT 6-7. FLASH LADAR IS IDEAL FOR DETERMINING REAL-TIME SPACECRAFT TRAJECTORY, SPEED AND ORIENTATION TO THE PLANET SURFACE, AS WELL AS EVALUATING POTENTIAL HAZARDS AT THE LANDING SITE IS REQUIRED FOR PRECISION LANDING. SLOPED GROUND, CRATERS, ROCKS AND SURFACE COMPOSITION ARE AMONG THE POTENTIAL HAZARDS. THE "FRAMING CAMERA" NATURE, OF FLASH LADAR SYSTEMS, MAKES THEM WELL SUITED AS HAZARD AVOIDANCE SENSORS FOR EDL. FLASH LADAR CAN PROVIDE A DIRECT, REAL-TIME MEASUREMENT OF THE ALTITUDE OF THE SPACECRAFT DURING DESCENT AS WELL AS SURFACE RELATIVE VELOCITY AND ORIENTATION, WHILE SIMULTANEOUSLY MAPPING THE TOPOGRAPHY OF THE TERRAIN BELOW TO IDENTIFY LANDING HAZARDS AND PROVIDE LOCALIZATION INFORMATION.

NNX09CA89C - ONE-METER CLASS DRILLING FOR PLANETARY EXPLORATION ROBOTIC PLANETARY EXPLORATION MISSIONS WILL NEED TO PERFORM IN-SITU ANALYSIS OF ROCK AND/OR REGOLITH SAMPLES OR RETURNING SAMPLES BACK TO EARTH. OBTAINING AND DELIVERING A SAMPLE CAN BE A COMPLEX ENGINEERING PROBLEM, ESPECIALLY IF IT'S DONE AUTONOMOUSLY THOUSANDS OF MILES AWAY. TO ACCOMMODATE FUTURE MISSIONS, THESE SUBSURFACE ACCESS AND SAMPLE HANDLING TECHNOLOGIES MUST BE DEVELOPED TO MEET A BROAD RANGE OF POTENTIAL REQUIREMENTS, INCLUDING A VARIETY OF ROCK OR SUBSURFACE MATERIALS, RIGOROUS SAMPLE PRESERVATION REQUIREMENTS, AND THE GENERAL PROBLEM OF AUTONOMOUS OPERATION IN THE PRESENCE OF DUST AND WITH LIMITED RESOURCES. THE ONE-TO-THREE METER RANGE HAS BEEN IDENTIFIED AS A CRITICAL REGIME FOR PLANETARY EXPLORATION AND WHILE THERE HAS BEEN SOME TECHNOLOGY DEVELOPMENT IN THIS REGIME, THERE IS CURRENTLY NO PROVEN FLIGHT-LIKE APPROACH TO ROBOTICALLY ACHIEVING THIS DEPTH THROUGH LAYERS OF CHALLENGING MATERIAL FROM REALISTIC ROVING OR LANDED PLATFORMS. THE PHASE 1 RESEARCH HAS RESULTED IN PROVING THE BENEFITS OF ROTARY-PERCUSSIVE DRILLING SYSTEM AS IT PERTAINS TO BREAKING OF FORMATION AND CUTTINGS TRANSPORT. THE PRIMARY OBJECTIVE OF THE PROPOSED EFFORT IS TO DEVELOP, VIA TESTING IN A SIMULATED MARS ENVIRONMENT, A BREADBOARD ONE-METER SAMPLING DRILLING SYSTEM FOR ACQUIRING A SMALL VOLUME OF DRILLED CUTTINGS AND A CORE (IF NECESSARY) FROM A TARGET DEPTH ON MARS. THIS PROJECT WOULD BUILD ON THE EXISTING KNOWLEDGE BASE OF MARS DRILLING, AND ITS PARTICULAR STRENGTH LIES WITH ITS CAPABILITY OF PERFORMING DRILLING TESTS UNDER SIMULATED MARTIAN CONDITIONS OF TEMPERATURE AND PRESSURE AND CO2 ATMOSPHERE. THIS IS A COMPONENT TECHNOLOGY EFFORT THAT INCLUDES THE DEVELOPMENT OF A ROTARY PERCUSSIVE DRILL HEAD AND A SAMPLING LEAD DRILL STRING. HONEYBEE ROBOTICS WILL LEVERAGE DRILL HEAD DEVELOPMENT BY UTILIZING VOICE COIL PERCUSSIVE ACTUATOR TECHNOLOGY DEVELOPED BY THE JET PROPULSION LABORATORY (JPL) FOR THE MARS SCIENCE LABORATORY POWDER DRILL.

NNX09CD99P - PRECISE THRUST ACTUATION BY A MICRO RF ION ENGINE BUSEK PROPOSES TO DEVELOP A RADIO-FREQUENCY DISCHARGE, GRIDDED MICRO ION ENGINE THAT PRODUCES N LEVEL OF THRUST PRECISELY ADJUSTABLE OVER A WIDE DYNAMIC THRUST RANGE. RF DISCHARGE WAS CHOSEN TO ELIMINATE THE LIFE-LIMITING INTERNAL CATHODE OF A DC DISCHARGE ION ENGINE. THRUST ACTUATION ON THE ORDER OF 0.03 N RESOLUTION IS PROPOSED WITH A CLOSED-LOOP CONTROL SYSTEM. THIS CONTROLLING SCHEME CAN BE ACHIEVED BY VARYING ONLY ONE PARAMETER: THE RF POWER WITH A FEEDBACK FROM THE BEAM CURRENT. UNIQUELY, THE RF ION ENGINE CAN ALSO PRODUCE ENOUGH THRUST FOR COARSE CONSTELLATION CORRECTIONS OR RECONFIGURATIONS. ARGON WILL BE THE BASE-LINED PROPELLANT TO EASE CONCERNS OF PROPELLANT CONDENSING ON OPTICS OR OTHER CRYOGENIC SURFACES. THIS FEATURE CAN BE CRITICAL FOR CLOSE FORMATION FLYING AS MICRO-THRUSTERS SUCH AS FIELD EMISSION ELECTRIC PROPULSION (FEEP) AND COLLOIDS COULD POTENTIALLY COAT NEIGHBORING SPACECRAFT. THE PROPOSED RF ION ENGINE, COMBINED WITH BUSEK'S SPACE-QUALIFIED CARBON NANOTUBE FIELD EMISSION CATHODE (DEVELOPED FOR THE ST7 DRS MISSION) AS A NEUTRALIZER, WILL CREATE A NEW OPPORTUNITY IN PRECISE THRUST ACTUATION. FURTHER IMPLEMENTATION OF A SIMPLE PROPELLANT FEED SYSTEM AND POWER ELECTRONICS WILL CREATE A COMPACT, LOW POWER, HIGH PERFORMANCE SPACECRAFT PROPULSION SYSTEM.

NNX09CE04P - HIGH REFLECTIVITY, BROAD-BAND SILVER COATING FUTURE SPACE TELESCOPES SUCH AS THE SUPER NOVA ACCELERATION PROBE (SNAP) REQUIRE EXCEPTIONALLY REFLECTIVE COATINGS APPLIED TO MIRRORS SEVERAL METERS IN DIAMETER. IN 2007, SURFACE OPTICS CORPORATION (SOC) APPLIED A PROTECTED SILVER COATING TO THE KEPLER SPACE TELESCOPE'S 1.4-M PRIMARY MIRROR. ALTHOUGH SOC'S COATING DESIGN MET THE REFLECTANCE REQUIREMENTS FOR KEPLER, THE PROTECTIVE LAYERS ABSORB TOO MUCH ENERGY IN THE UV AND VISIBLE SPECTRAL REGIONS TO MEET SNAP'S SCIENCE OBJECTIVES. IN THIS RESEARCH, SOC WILL IMPROVE THE SPECTRA PERFORMANCE OF ITS CURRENT PROTECTED SILVER COATING, BY MODIFYING THE PROTECTION CHEMISTRY, AS WELL AS, THE DEPOSITION PROCESS. SOC'S SILVER COATING DESIGN IS BASED ON A PROTECTION RECIPE PATENTED BY LAWRENCE LIVERMORE NATIONAL LABORATORY (LLNL). RECENT SOC IRAD RESULTS SHOWED THAT SIGNIFICANT MODIFICATIONS TO THE BASIC LLNL PROTECTION SCHEME ARE POSSIBLE, WITHOUT SACRIFICING COATING DURABILITY. IN PHASE I, A VARIETY OF PROTECTIVE COMPOUNDS WILL BE FABRICATED BY AN ION-ASSISTED EVAPORATION PROCESS AND OPTIMIZED FOR THEIR PROTECTIVE PROPERTIES, ADHESION CHARACTERISTICS, AND EFFECT ON COATING REFLECTIVITY. IN ADDITION, SOC WILL CREATE A MORE PRECISE METHOD TO DEPOSIT PROTECTIVE NICRNX ATOMIC CLUSTERS, WHICH ARE A CRITICAL ELEMENT OF LLNL'S SILVER PROTECTION RECIPE. BY MODIFYING SOC'S EVAPORATION SYSTEM AND MONITORING PROCESS, IT IS EXPECTED THE NECESSARY VOLUME OF THESE HIGHLY ABSORBING CLUSTERS MAY BE REDUCED BY A FACTOR OF 2, WHILE STILL PROVIDING ADEQUATE ENGINEERING MARGIN TO INSURE DURABILITY. THESE MODIFICATIONS WILL SIGNIFICANTLY IMPROVE COATING REFLECTANCE IN THE UV AND VISIBLE SPECTRAL REGIONS. IN PHASE II, SCALE-UP ISSUES WILL BE ADDRESSED AND THE IMPROVED SILVER COATING PROCESS WILL BE APPLIED TO A 2.2-M MIRROR SUBSTRATE IN SOC'S 3.3-METER VACUUM COATING CHAMBER.

NNX09CA81C - COLLOID THRUSTER FOR ATTITUDE CONTROL SYSTEMS (ACS) AND TIP-OFF CONTROL APPLICATIONS BUSEK PROPOSES TO DEVELOP AND DELIVER A COMPLETE ENGINEERING MODEL COLLOID THRUSTER SYSTEM CAPABLE OF THRUST LEVELS AND LIFETIMES REQUIRED FOR SPACECRAFT OPERATIONAL TASKS SUCH AS TIP-OFF DE-TUMBLING AND ATTITUDE CONTROL. THE SELF CONTAINED THRUSTER SYSTEM SHALL BE CAPABLE OF DELIVERING 75AUN WITH SUFFICIENT TOTAL IMPULSE TO DE-TUMBLE SPACECRAFT SUCH AS LISA. THE PROPOSED PHASE 2 WORK BUILDS UPON A HIGHLY SUCCESSFUL PHASE 1 EFFORT WHERE THE KEY PRINCIPALS OF THE INNOVATION, A PROPELLANT ISOLATION MEMBRANE AND A PASSIVE CAPILLARY FEED SYSTEM, WERE UNEQUIVOCALLY DEMONSTRATED. THE PROPOSED SYSTEM IS COMPLETELY PASSIVE WITH NO MOVING PARTS AND REQUIRES NO VALVES TO ENSURE ITS HIGH RELIABILITY. IN ORDER TO INHIBIT PROPELLANT CONTAMINATION PRIOR TO OPERATION IN SPACE, A UNIQUE ISOLATION MEMBRANE WILL SEPARATE PROPELLANT FROM THE EMITTER. UPON HEATING THE ISOLATION MEMBRANE DISSOLVES, ALLOWING PROPELLANT FROM A COLLOCATED RESERVOIR TO FLOW FORWARD TO THE ELECTROSPRAY THRUSTER WITHOUT CONTAMINATION. THE THRUSTER CONSISTS OF AN ARRAY OF SELF ADJUSTING EMISSION SITES THAT ARE ACTIVATED BY APPLICATION OF AN ELECTRIC FIELD THAT INITIATES EMISSION. THE DELIVERED THRUST IS MODULATED BY VARYING THE APPLIED ELECTRIC FIELD. THE SIGNIFICANT INNOVATIONS OF THE PROPOSED COLLOID THRUSTER INCLUDE: A COMPACT, LOW POWER, MODULAR THRUSTER SYSTEM CONTAINING NO MOVING PARTS, WHICH IS CAPABLE OF DELIVERING SUFFICIENT THRUST FOR SPACECRAFT TIP-OFF CONTROL AND ACS APPLICATIONS.
