There is no rad hard SDRAM currently available to support DDR2 and DDR3 applications. Space Micro proposes to build a radiation hardened by design (RHBD) SDRAM memory, using a modified version of our HF-Core Memory Controller to solve all the single event effects issues (SEU, SEFI and multiple bit errors). The RHBD SDRAM will be manufactured on known radiation characterized eDRAM (embedded DRAM) ...

The objective of this proposal is to develop three unique energy harvesting technologies utilizing our existing research strengths that will be of interest and utility to NASA applications and environmental conditions. By developing multiple technologies, NASA will be able to harvest energy from multiple waste energy sources, namely environmental vibrations, thermal energy, and solar flux. These d ...

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.

To provide additional telemetry and data for long-term mission, the composition of internal atmosphere of spacesuits must be determined. Specifically, the unambiguous detection and quantification of carbon dioxide is crucial for mission completion. Detection of other gasses (ammonia, oxygen) is also necessary for a complete sensor suite. Seacoast Science and Case Western Reserve University pro ...

Plasma Controls, LLC (SBC) and Colorado State University (RI) will mature an energy and species plasma diagnostic for use with plasma thrusters. The combined Energy and Velocity Analyzer for Distributions of Electric Rockets, or the lsquo;E-VADERrsquo;, is needed especially for characterizing the plasma plume of Hall thrusters, where researchers desire to know ion energies and charged species frac ...

Today many spacecraft carry two propulsion options: high thrust required for high acceleration maneuvers such as orbit insertion and rapid response; and low thrust required for station keeping and less critical maneuvers. A new class of non-toxic monopropellants, such as AF-M315E and LMP-103S, perform well in both high and low thrust regimes. Significant investments are maturing both monopropellan ...

Mapping spectrometers have been extremely useful in multiple NASA applications, from Earth climate monitoring to identifying hydrocarbon lakes on Titan. Traditionally, imaging spectroscopy systems are not only heavy but also large in order to accommodate the long path lengths needed for spectral separation. There are several varieties, such as push-broom and scanning imaging spectrometers, but h ...

As the desire to look deeper in space and image multiple objects simultaneously continues to grow, the need for larger telescopes is raised. With this increase in aperture size, the instrumentation size is increased proportionally and the cost of this instrumentation is proportionally squared. With advances in photonic technologies this can be accomplished on a fully integrated chip. Integrated ph ...

Lithium niobate (LiNbO3) has been long regarded as the most attractive material for electro-optic modulation for high-performance optical communication systems of up to 100 GHz, as well as for its superior second-order optical non-linearity. The weakly confined LiNbO3 waveguides formed by diffusion or implantation of dopants do not lend themselves to high-level chip integration. One key novel tech ...

Research in Flight (RIF) and Auburn University are offering the development of an advanced, robust tool and methodology that allows the simulation and modeling of gust and wake vortex encounters for Distributed Electric Propulsion (DEP) enabled Urban Air Mobility (UAM) vehicle concepts. DEP enabled UAM concepts offer the potential for large performance improvements by exploiting favorable synergie ...
