We propose to develop a high-efficiency, triple-junction, epitaxial lift-off (ELO) solar cell by incorporating quantum dots (QDs) within the current-limiting subcell. We intend to leverage existing QD epitaxy processes developed by the Rochester Institute of Technology and combine this with MicroLink's expertise in multi-junction cell growth and ELO technology. We will employ QDs to enhance ...

Middle-wave infrared (MWIR, 3-5¿¿m) photodetectors are of great importance in numerous NASA applications, including thermal remote sensing for carbon-based trace gases (CH4, CO2, and CO), heat capacity mapping for earth resource locating, environment and atmosphere monitoring, and IR spectroscopy. However, existing MWIR photodetectors are require a low operating temperature, below 77K to achieve ...

Infrared spectroscopy is an invaluable detection and measurement tool intensively used in Earth Science, Solar Physics and Astrophysics experiments pursued from satellite platforms. The geometrical characteristics and sensitivity of satellite infrared spectroscopy systems is often determined or limited by their optical elements. Improvements in optical components allow one to reduce the mass and i ...

Aerodyne Research, Inc. and the University of Massachusetts at Amherst will collaborate to develop laser desorption ionization (LDI) mass spectrometric analysis of organic analytes of interest in planetary exploration, based on microchip laser illumination. The key advantage of microchip lasers in this application is their much smaller size and weight than lasers used to date for LDI. These lase ...

Agiltron proposes to develop an extremely compact and high sensitivity uncooled near- and mid-infrared (NMIR) spectrometer engine for planetary compositional analysis and mapping. In this program, we will produce lead salt-based IR detector materials with single crystalline-like oriented thin film structures which will increase the majority charge carrier mobility by two orders of magnitude. Excep ...

Surface exploration of planetary environments with current robotic technologies relies heavily on human control and power-hungry active sensors to perform even the most elementary low-level functions. Ideally, a robot should be capable of autonomously exploring and interacting within an unknown environment without relying on human input or suboptimal sensors. Behaviors such as exploration of unkno ...

The innovation being developed in this program is a Mg Hall Effect Thruster system that would open the door for In-Situ Resource Utilization based solar system exploration. Magnesium is light and easy to ionize. Performance advantages of a Mg thruster include far higher specific impulse and less life limiting erosion. Additional advantages include low propellant cost and low pressure propellant ...

The goals of reducing total cost and increasing reliability and safety of access to space continue to be top priorities for NASA. The most immediate propulsion launch challenge involves increasing lift weight from 70 to 130 metric tons by developing the heavy lift Space Launch System (SLS). Solid rocket motor analysis tools are needed to simulate ignition and propellant recession during the burn ...

During Phase I, Busek designed and manufactured an electrospray emitter capable of generating 20 mN in a 7" x 7" x 1.7" package. The thruster consists of nine porous-surface emitters operating in parallel from a common propellant supply. Each emitter is capable of supporting over 70,000 electrospray emission sites, with the plume from each emitter being accelerated through a single aperture, eli ...

Physical Sciences Inc. (PSI) and Orbitec Inc. propose to develop a unique chemical propulsion system for the next generation NASA science spacecraft and missions that is compact, lightweight, and can operate with high reliability over extended periods of time and under wide range of thermal environments. The system uses a new storable, low toxicity, liquid monopropellant as its working fluid. In P ...
