Robots will play an important role in NASA#39;s upcoming missions to the Moon and beyond.nbsp; They will need to manipulate their environment in complex and useful ways - carrying objects, using tools, and assisting crew.nbsp; NASArsquo;s humanoid robots have highly dexterous end-effectors, but developing software to fully utilize such hands remains a challenging task.nbsp; Grasping strategies are ...

SUPER ACCURATE ADAPTIVE COMPUTATIONAL SCHEMES FOR THE ANALYSIS OF FLUID STRUCTURE INTERACTION AND COMPLEX THREE-DIMENSIONAL INTERNAL FLOWS ARE TO BE DEVELOPED. NEW PETROV-GALERKIN FINITE ELEMENT METHODS FOR SOLVING THE NAVIER-STOKES EQUATIONS. COUPLED WITH THE EQUATIONS OF MOTION OF ELASTIC DUCTS AND MANIFOLDS, ARE TO BE DEVELOPED AND USED TO SIMULATE FLOWS IN AEROSPACE PROPULSION SYSTEMS (SUCH AS ...

THE GOAL OF PHASE I IS DEVELOPMENT OF AN ADVANCED OPTICALLY PUMPED HELIUM MAGNETOMETER CONCEPT. THIS INSTRUMENT WILL MEASURE MAGNETIC FIELDS IN THE 1 TO 10-8 GAUSS RANGE WITH ORDER OF MAGNITUDE IMPROVEMENTS IN SENSITIVITY AND ABSOLUTE ACCURACY OVER EXISTING MAGNETOMETERS. OPTICALLY PUMPED HELIUM ISOTOPES CAN BE OPTICALLY PUMPED AND USED AS MAGNETOMETERS IN THE FOLLOWING THREE MODES: (1) VECTOR MOD ...

Frequency selective surfaces (FSSs) are periodic arrays of conductive elements/patches that cause a particular reflection response when illuminated with high frequency electromagnetic energy. nbsp;These arrays arenbsp;used for high frequency filters and in antenna applications.nbsp; We propose to use FSSs as multi-functional sensors. nbsp;FSS sensors are unpowered, low-profile (thin), wireless and ...

A solid state yet rapidly tunable etalon based on liquid crystal (LC) etalon technology is constructed using minimized LC birefringence response time in an optimized electric field. The key technological innovation is the use of liquid crystal to tune the etalon.nbsp;nbsp;While this type of etalon has been in use for many years, a development effort is undertaken to reduce the time it takes to tun ...

IT IS GENERALLY ACCEPTED THAT HIGHER PLANTS WILL SERVE AS IMPORTANT COMPONENTS OF ENVIRONMENTAL CONDITIONING AND FOOD PRODUCTION SYSTEMS FOR FUTURE SPACE OR PLANETARY SURFACE HABITATS. BECAUSE OF STRUCTURAL CONSIDERATIONS IT IS LIKELY THAT ATMOSPHERIC COMPOSITION AND PRESSURE WILL BE RADICALLY DIFFERENT. IN DEFINING GROWTH SYSTEMS FOR ALTEREDATMOSPHERES WE MUST UNDERSTAND HOW PLANTS OPERATE IN GEN ...

GLSV proposes building a fully featured NASA Auralization Framework (NAF) plug-in which uses acoustic ray tracing techniques in order to fill this need.nbsp; GLSV has determined that acoustic ray tracing is the best choice for a technology which can provide a reasonable fidelity model which can be solved over length scales seen in urban environments.The proposed software is in response to NASArsqu ...

NASArsquo;s 2018 SBIR solicitation topic A3.02 requests ldquo;Autonomous systems to produce any of the following system capabilities: Prognostics, data mining, and data discovery to identify opportunities for improvement in airspace operations.rdquo; Identifying opportunities for improvement is a critical ongoing need in the air traffic management domain, for which achieving high levels of perform ...

The requirement of detecting nearly ten orders of magnitude smaller signal of a planet compared to the nearby star puts forward extreme challenges for coronagraphs designed for exoplanet imaging. Vector vortex waveplates (VWs) appear to be capable of providing best performance compared to other mask technologies due to their structure as thin film coatings of continuous texture that minimizes ligh ...

The Interdisciplinary Consulting Corporation (IC2) proposes to continue development of dual-axis shear stress sensors that are applicable in ground test facilities covering a large range of flow speeds in response to NASA SBIR 2018 Phase I solicitation subtopic A1.08. The proposed sensing system addresses a critically unmet measurement need in NASArsquo;s technology portfolio, specifically the abi ...
