The proposed effort concerns technologies related to cryogenic propellant production, storage, transfer, and usage to support NASArsquo;s in-situ resource utilization (ISRU) goals. nbsp;They include a broad range of applications, scales, and environments consistent with future NASA missions to the Moon and Mars.nbsp;nbsp;More specifically, the project will addressnbsp;development of a piecewise-sm ...

Achieving trustworthy and trusted autonomy starts early in the development process through performing hazard analysis, fault analysis, identifying mitigating requirements, and carefully and rigorously tracing those requirements all the way into design, models, implementation, and tests. However, traceability can be time-consuming, costly, and error-prone. To address these challenges, significant a ...

GTLrsquo;s breakthrough ultra-lightweight composite dewar-tank technology is game changing by providing hydrogen weight fractions in excess of 59% for small tanks, with over 70% achievable with medium scale LH2 tanks, including vacuum insulation. This capability addresses a critical need in the conversion of single-aisle aircraft from Jet-A to liquid hydrogen to eliminate carbon emissions. With GT ...

Single-event burnout (SEB) and gate rupturenbsp;occur when high-energy ions strike SiC MOSFET devices in the OFF state. Heavy ion radiation caused irreversible damage (possibly owing to SEGR) at biases below 10% and catastrophic failure at biases below 40% of their nominal blocking voltage in commercial SiC power devices. Commercial SiC MOSFETs degrade fornbsp;latent gate leakage even at 50V drain ...

Ultrasonic Technology Solutions (UTS) is based in Knoxville, Tennessee, and formed as a spin-off start-up from Oak Ridge National Laboratory (ORNL) is proposing to develop an ultra-fastnbsp;ultrasonic washing and dryer combination for space applications.NASArsquo;s Life Support and Habitation Systems Focus Area seeks key capabilities and technology solutions that enable extended human presence in ...

With the Artemis program, NASA currently plans to land the first woman and next man on the moon by 2025, using innovative technologies to explore more of the lunar surface than ever before. The need for oxygen extraction from lunar regolith has been identified by the STMD (Space Technology Mission Directorate). Successful oxygen extraction from the abundant regolith resources would enable extended ...

This project will advance technology for the automated assembly of large truss towers.nbsp; Assembly of truss-based structures is one of the leading candidates for establishing some of the early lunar infrastructure.nbsp; Specifically, joining technologies and robotic tools are required to enable autonomous/automated assembly of tall towers as well as shelters, domes and habitats.nbsp; Automated a ...

Machine Learning (ML) and Artificial Intelligence (AI) have matured to the point where they are being used throughout many modern applications. nbsp;Explainable AI (XAI) ndash; AI in which humans can understand the decisions or predictions made by the AI system ndash; is becoming critical for many applications, including Air Traffic Management (ATM). In contrast, ML-enabled and AI-enabled systems ...

This effort combines speech analytics, Speed to Text (STT) translation software, and intent inference algorithms in order to assess aviation system safety.nbsp; Each of these components has a different perspective on spotting potential off-nominal and anomalous conditions, for instance, in the way people speak under stress and high workload, the mis-communications and mishearing of key words in a ...

Whether in industry, at home, or in the lab, most fluids handing operations and equipment would fail immediately when directly employed in the microgravity environments of orbiting or coast spacecraft. This is due to the innate assumption of gravity in nearly everything we do, make, and think. Thus, special engineering considerations must be made to account for the large length scale inertial-visc ...
