One of the objectives of the In-Situ Resource Utilization (ISRU) RESOLVE project was to extract water from lunar regolith by heating and then capturing and quantifying the released water. A potentially large error in...

Carbon nanotubes (CNTs) have attracted much attention due to their extraordinary mechanical and unique electronic properties. CNTs are being studied for applications in high-strength/low-weight composites and other applications. In order to alter the CNT properties for particular applications, chemical...

Laser and electro-optic technologies are under development to remotely measure sodium (Na) by adapting existing LiDAR technology with spaceflight heritage. The developed instrumentation will serve as the core for planning a heliophysics mission targeted to study the composition and dynamics of...

This innovation addresses several critical issues in the construction of cut control volumes using embedded-boundary Cartesian mesh generators. The innovation considers the case of a surface triangulation intersecting the face of a Cartesian hex...

X-ray astronomy offers the opportunity to observe important phenomena, including the early accretion of massive black holes and detecting diffuse ionized intergalactic gas that is heated to X-ray temperatures...

Robotic servicing of a satellite in low earth orbit (LEO) or geosynchronous Earth orbit (GEO) requires advanced systems capable of meeting the harsh environments of space. To support this effort, the Goddard Space Flight Center Satellite Servicing Capabilities Office (SSCO) has...

This compact, lightweight trap vent is used to minimize the pressure differential of a high-altitude, balloon-borne detector. The vent allows the pressure to equalize rapidly, yet does not allow any light to enter the detector.

Landers to large planetary bodies such as Mars typically use a secondary reconnaissance spacecraft to generate high-fidelity 3D terrain maps that are subsequently used for landing site selection and creating...

The purpose of the GPS Satellite Geometry Analysis Tool (GPSGEM) is to evaluate GPS satellite geometry for a given Earth-fixed location or for a provided trajectory. The tool will generate a listing of all satellites in view, the best satellite combination defined by the most optimum Geometric Dilution...

Innovators at NASA's Glenn Research Center have developed several new technological innovations to improve the capability of Hall-effect thrusters, which are used primarily on Earth-orbiting satellites and can also be used for deep-space robotic vehicles. Hall thrusters are susceptible to discharge channel...
