This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed.Process optimizations will be conducted ...

To address the urgent need for 3D flash-lidar technology for landing on solar system bodies and for spacecraft rendezvous and docking with satellites, an effort is proposed to fabricate, characterize, and test a versatile, high-sensitivity InGaAs APD 3D flash lidar and to advance the technology-readiness level (TRL) of lidar technologies suitable for NASA mission requirements. Leveraging an existi ...

The experience of building the NEA Scout solar Sail resulted in the realization that new manufacturing technology would be required to build solar sails significantly larger than NEA Scout. During Phase I, NeXolve successfully developed and demonstrated fab and fold processes and scalable-modular pathfinder mechanisms that can be fully developed to support fabrication and packaging of larger solar ...

In the next decade, quantum technologies will provide revolutionary advances in communications, sensing and metrology, information processing, timekeeping, and navigation. Of particular interest to this NASA solicitation is the transformative potential of quantum technology in the realm of communications. Furthermore, transmission of quantum information over arbitrary distances raises new possibil ...

We propose to implement two new sensing modalities comprising the Multimodal Agile Ranging and Velocimetry INstrument (MARVIN) using a novel acousto-optic Structured Light Imaging Module (SLIM) previously developed under the NASA PIDDP program for planetary rover navigation and geomorphology.nbsp;Based on an acousto-optic illumination engine, SLIM consumes only 10-20W of power, weighs less than a ...

The goal of the project is to develop an intelligent framework to construct adaptive parametric reduced order model (PROM) database for aeroservoelastic (ASE) analysis and aerostructural control. In Phase 1, the framework for both equation-based and data-driven PROMs was developed and feasibility to introduce ldquo;engineering intelligencerdquo; to AE/ASE ROMs was successfully established. Careful ...

The National Academies Decadal Strategy and NASA have identified critical earth observations including Surface Deformation and Change andnbsp; Clouds, Convection and Precipitation.nbsp; These observations are well suited to synthetic aperture radar instruments.nbsp; The missions span operating frequencies from L to Ka Band. nbsp;Precision mesh reflectors are uniquely suited to provide large freque ...

Silver and its compounds are of significant appeal as biocides for long-duration space missions, as they are capable of destroying or inhibiting the growth of a wide spectrum of microorganisms including bacteria, viruses, algae, molds and yeast, while exhibiting low toxicity to humans. The general pharmacological properties of silver are based upon the affinity of silver ion for biologically impor ...

The proposed effort is to develop a versatile, high-definition (HD) 3D camera that provides in real time high-resolution image and distance data over a large angle for monitoring human activity from a free-flying robot platform.nbsp; The objective is to build a compact sensor payload package that is compatible with the Astrobee free-flying robot, which includes meeting size, weight, power and comm ...

A new thin-film polymer material is proposed that would improve orbit lifetimenbsp;and packaging efficiency for use in Low Earth Orbit (LEO) and Micro-Meteoroid and Orbital Debris (MMOD) prone applications.nbsp; Thin-film polymers are used in many spacecraft applications including multi-layer insulation, sunshields for thermal control, deployable structures, solar sails, as well as flexible solar ...
