We propose a spectrometer that employs a single room temperature semiconductor detector that can perform both gamma and neutron spectroscopy. The proposed detector is based on the novel mercurous halide materials, Hg2X2 (X=I, Cl, Br). The mercurous halides are new wide band-gap semiconductor detector materials that can provide radiation detection with low cost, high performance and long term stab ...

Radiation detectors that sense gamma and neutron radiation are critical to the exploration of planetary surface composition. Among the key technological challenges is to have a suitable detector that not only can be used for both gamma ray and neutron detection, but also satisfy the many highly desirable and essential for spaceflight properties: good energy resolution, high efficiency, high radiat ...

TDA Research Inc.(TDA) in collaboration with University of Puerto Rico ? Mayaguez (UPRM is proposing to develop a highly efficient CO2 removal system based on UPRM proprietary strontium exchanged silico-alumino-phosphate (Sr-SAPO-34) for closed loop space craft cabin air re-vitalization during deep space missions.

GTL has been developing a suite of transformational technologies that have the capability to disrupt the traditional launch vehicle paradigm. BHL composite cryotank technology provides a four times improvement over large aluminum iso-grid tanks, offering a 6 percentage point improvement in small stage PMF. Superior Stability Engine is an innovative liquid rocket engine configured to maximize comb ...

The proposed technology builds off GTL's advanced solid ramjet fuel. The method uses additive manufacturing methods to produce an innovative new type of fuel grain that regresses quickly and has a high Isp and combustion efficiency. With this technology, the performance of a liquid rocket engine can be had with a hybrid rocket system. This technology allows for a simple, low cost, high performanc ...

GTL?s SNS technology aids in the operation of new or existing structural health monitoring (SHM) systems by integrating data and power pathways into the structure. The use of this technology within a composite structure would allow engineers to place sensors from an SHM system directly where they are needed on a structure with instant power. GTL?s SNS technology offers the potential for developers ...

DEC-Shield technology offers the means to generate electric power from cosmic radiation sources and fuse dissimilar systems and functionality into a structural component to create a Multi-functional Structure (MFS). DEC-Shield integrated into MFS technology can be used to generate electric power and provide radiation protection in a space vehicle; even maximizing that protection by spreading the ...

Extravehicular Mobility Units (EVU) are the necessary to perform elaborate, dynamic tasks in the biologically harsh conditions of space from International Space Station (ISS) external repairs to human exploration of planetary bodies. The EVUs have stringent requirements on physical and chemical nature of the equipment/components/processes, to ensure safety and health of the individual require prop ...

Computational fluid dynamics (CFD) simulations are routinely used by NASA to optimize the design of propulsion systems. Current methods for CFD modeling rely on general materials properties to determine fluid structure interactions. This introduces uncertainty when modeling extreme conditions, where materials degrade and properties may change as a consequence. This also limits the use of CFD as a ...

High-energy space radiation from Galactic Cosmic Rays and Solar Particle Events (SPEs) pose significant risks to equipment and astronaut health in NASA missions. In particular, energetic particles from SPEs associated with flares and coronal mass ejections (CMEs) constitute a highly dynamic and penetrating radiation environment that may adversely affect not only beyond-Low-Earth-Orbit missions, bu ...
