City planners and engineers need detailed assessments of public rights-of-way to evaluate existing conditions, determine compliance with draft accessibility guidelines, and plan reconstruction projects. Current assessment methods are inadequate and inefficient due to the time and resources required. This project will develop an automated public rights-of-way assessment process and the measuremen ...

The hundreds of stream cores in the latest graphics processors (GPUs), and the possibility to execute non-graphics computations on them, open unprecedented levels of parallelism at a very low cost. In the last 6 years, GPUs had an increasing performance advantage of an order of magnitude relative to x86 CPUs. Furthermore, this performance advantage will continue to increase in the next 20 years be ...

Ultrastable, narrow linewidth, high reliability MOPA sources are needed for high performance LIDARs in NASA for, wind speed measurement, surface topography and earth and planetary atmosphere composition measurements. Princeton Optronics is developing a MOPA laser source for these applications. Phase I experiments concluded that the optimum approach will use a DPSS microchip laser with the SOA. Th ...

For this project Superior Graphite Co. (Chicago, IL, USA), the leading worldwide industrial carbon manufacturer and the only large scale battery grade graphitic carbon producer in the USA, will develop, explore the properties of, and demonstrate the enhanced capabilities of novel nanostructured SiLix-C anodes, capable of retaining high capacity at a rapid 2 hour discharge rate and at 0oC when used ...

There is demand for vastly improved deep space satellite communications links. As data rates dramatically increase due to new sensor technologies and the desire to pack even more sensors on spacecraft, it is imperative that new solutions be compact in size, light in weight, be high speed, and highly power efficient. NASA has recognized optical links offer potential improvements in power and in si ...

The Phase I effort conceived a novel method for ISRU oxygen extraction and liquefaction from lunar regolith, repre-senting a significant advance in the state of the art. The approach uses solar photovoltaics as a power source to heat and extract oxygen with highly favorable system metrics, capable of achieving TRL 3 during a Phase II effort and TRL 6 in earth gravity during Phase III. Autonomy of ...

We will develop an efficient tool for formal verification of PowerPC 750 executables. The PowerPC 750 architecture is used in the radiation-hardened RAD750 flight-control computers that are utilized in many space missions. The resulting tool will be capable of formally checking: 1) the equivalence of two instruction sequences; and 2) properties of a given instruction sequence. The tool will automa ...

A team of CU Aerospace, the University of Illinois, and ManTech SRS Technologies proposes Phase II development of a 3 kg CubeSat spacecraft for initial flight test of a 20 m2 UltraSail, a next-generation high-risk, high-payoff solar sail system for the launch, deployment, stabilization and control of very large (km2 class) solar sails, enabling very high payload mass fractions for interplanetary a ...

The innovation in this Phase II SBIR is the development of a technology which will enable the manufacture of a lightweight, low cost, high radiation resistance InP based solar cells with high efficiency suitable for space power systems. The key technological step is the application of a production-worthy epitaxial liftoff (ELO) process to a multijunction solar cell structure fabricated on a large ...

NASA calculation that over a kg of packaging waste are generated per day for a 6 member crew. This represents over 1.5 metric tons of waste during a Mars mission. Currently, these wastes are considered a disposal burden. However, packaging can designed to have valuable secondary uses which can lighten other payloads. These include: Light generation, electricity generation, storage structures, ...
