The Positrusion ISS Recycler enables recycling of scrap and waste plastics into high-quality filament for 3D printers to enable sustainable in-situ manufacturing on the ISS and future deep-space manned missions. In order to minimize astronaut time required for recycling, mitigate safety risks, and improve the quality of product relative to conventional filament extrusion methods, Tethers Unlimite ...

BECAUSE OF THE COMPLEXITY OF THE HELICOPTER FLOW FIELD, A ZONAL METHOD OF ANALYSIS OF COMPUTATIONAL AERODYNAMICS IS REQUIRED. IN THIS RESEARCH, A NEW PROCEDURE FOR COUPLING POTENTIAL AND VISCOUS FLOW CALCULATION SCHEMES IS PROPOSED. AN OVER-LAPPING, VELOCITY-COUPLING TECHNIQUE IS TO BE DEVELOPED WITH THE UNIQUE FEATURE THAT THE POTENTIAL FLOW SURFACE SINGULARITY STRENGTHS ARE OBTAINED DIRECTLY FRO ...

The goal of this proposal is it to use computational protein design to develop a set of stable, non-immunogenic enzymes for G-agent and V-agent neurotoxin deactivation based on an engineered human PON1 scaffold suitable for mass production. Chemical warfare nerve agents (CWNAs) have existed for over a century and remain a serious threat to the safety of mankind. Therapeutic enzyme treatments offer ...

The Trusselator technology will enable on-orbit fabrication of support structures for high-power solar arrays and large antennas, achieving order-of-magnitude improvements in packing efficiency and launch mass while reducing life-cycle cost. The Phase I Trusselator effort successfully demonstrated fabrication of continuous lengths of high-performance carbon fiber truss using a novel additive manu ...

Studies in ground-based analogs of Isolated and Confined Environments (ICE) have identified sensory monotony and social isolation as threats to crew psychological well-being. Further, the lack of real-time communications in future missions will impact crew interactions with their support systems, i.e. family, friends, and colleagues, are critical. ANSIBLE (A Network of Social Interactions for Bi ...

NASA has identified a clear and pressing need for education of both local decision makers and the local flying and nonflying public to enable AAM operations to commence in a timely manner. The goal of this research effort is to develop a robust and cost-conscious capability to support local organizations and local decision makers with materials that support community education, engagement, and out ...

A robust relative navigation software capability is a key enabler of all RPOD missions, and therefore an essential technology to unlock ISAM capabilities. There are two areas of development that are needed to advance relative navigation towards onboard autonomous viability: 1) Improvement of machine vision and image processing performance in spaceflight applications and 2) Development of a navigat ...

This proposal responds to the need for new technologies to effectively manage and streamline complex fault management (FM) systems, enable rapid diagnostic model generation and validation, and provide tools to perform FM analyses and trades e.g., fault containment regions (FCRs), redundancy management, and sensor placement. Okean Solutions proposes to significantly improve FMnbsp;system modeling a ...

Liquid rocket developers have identified advanced engine concepts that are not feasible due to manufacture due to limitations in currently available technologies. Specifically, engine developers are in need of a manufacturing technology that is capable of generating cooling channels in liquid rocket nozzles and combustion chambers at low cost, while supporting increasingly complex designs (see a ...

A novel injectornbsp;is proposed in response to quot;Robust design solutions for liquid oxygen injection and subsequent stable combustion with high temperature (gt;1700 R) hydrogen flowing at low pressure (lt;25nbsp;psia) and high velocity (~Mach 0.2)quot; subtopic, listed undernbsp;quot;Advanced Propulsion Systems Ground Test Technologyquot; focus area.nbsp; This injector features fully 3D-printe ...
