Foldable and Deployable Power Collection System

The lightweight solar power array can be used in electric vehicles, portable and field-deployable power systems, and power for emergency response operations.

NASA’s Marshall Space Flight Center is developing a lightweight space-based solar power array with a high power-to-stowed-volume and weight ratio. The system provides power to small satellites and CubeSats that are power starved, operating on extremely limited power because of the size restrictions for housing onboard power sources. The beauty of NASA’s new solar unit is in its simplicity and packaged power density. Small satellites cannot take advantage of deployable high-efficiency solar cell arrays due to their complexity and mechanical needs; the weight and volume requirements exceed what is available in small satellites and CubeSats. The new system, for example, is compact enough to provide a 3U CubeSat with ~200 Watts, or a 6U with 500 Watts of power. NASA is developing the technology and is looking for partners to license and commercialize it.

Iodine-Compatible Hall Effect Thruster

The use of iodine reduces the technical demands on thruster design.

The Hall effect thruster (HET) was designed for long-duration operation with gaseous iodine as the propellant. Iodine is an alternative to the state-of-the-art propellant xenon. Compared to xenon, iodine stores as a solid at much higher density and at a much lower pressure. Because iodine is a halogen, it is reactive with some of the materials with which a Hall thruster is typically constructed. Through research and testing, the new method allows for the HET to be used with iodine propellant for long periods of time.

An Alternative Molecular Sexing Method for the Florida Scrub-jay

John F. Kennedy Space Center, Florida

A new method of molecular sexing is described that helps to understand population dynamics of the Florida Scrub-jay (FSJ). FSJ is an endemic, nonmigratory, monomorphic species of bird found on the Florida peninsula in lowgrowing oak or pine scrub. The current conservation status listed for the FSJ is threatened and vulnerable to extinction.

Surface Water Ocean Topography (SWOT) Science Simulator

This program simulates ocean topography observations for generating ocean circulation models.

NASA’s Jet Propulsion Laboratory, Pasadena, California

The SWOT Science Simulator simulates projected SWOT altimetry observations that can be applied to an ocean general circulation model, allowing the exploration of ideas and methods to optimize information retrieval from the proposed SWOT Mission, which is currently baselined to launch in 2020.

Digital Elevation Model Maker (DEMmaker)

Lyndon B. Johnson Space Center, Houston, Texas

The DEMmaker suite of software applications produces data products containing surface shape, reflectivity, and geomorphology (craters and rocks) for a desired planetary surface based on statistically accurate size and frequency distributions of geologic and surface impact features. The current version can produce models at virtually any resolution or size for any location on the Moon. Remote sensing data can be incorporated to underlie the synthetic landscape with real data where available. The software suite is driven by a graphical user interface (GUI) that lets the user specify which tools of the suite to run, allowing flexibility in the products output by the package.

Terrestrial Observation and Prediction System (TOPS)

Ames Research Center, Moffett Field, California

TOPS is a modeling software system that integrates data from satellite, aircraft, and ground sensors, and weather/climate models with application models to expeditiously produce operational nowcasts and forecasts of ecological conditions. TOPS allows determination of the options for different socio-economic and resource management approaches to dealing with fluctuations within our biosphere, and will help in mitigating potential negative impacts.

Characteristics of the Spliced Kennedy Space Center Doppler Radar Wind Profiler Database

Marshall Space Flight Center, Alabama

NASA relies on the Natural Environments (NE) Branch located at Marshall Space Flight Center (MSFC) to provide databases that represent the wind magnitudes and wind changes expected on day-of-launch (DOL) for vehicle programs that MSFC NE supports. MSFC NE has traditionally utilized weather balloon measurements to generate the wind profiles used in DOL loads and trajectory simulations. However, balloon measurement archives have three limitations in that (1) they do not contain a large enough sample to adequately represent the wind environment at extreme percentiles, (2) balloons could misrepresent the aloft wind environment due to their rise rate and drift characteristics, and (3) the Space Shuttle Program’s operational requirements significantly drove the atmosphere databases’ development. To help mitigate these limitations, MSFC NE used the 50-MHz Doppler Radar Wind Profiler (DRWP) at Kennedy Space Center (KSC) to validate balloon measurements on DOL during the SSP.

Hydrogen Peroxide for Microbial Growth Control in Space Potable Water Systems

This on-demand generator can provide the needed hydrogen peroxide levels for microbial growth control in potable water holding tanks and waterlines.

Marshall Space Flight Center, Alabama

NASA uses a biocide to prevent contamination of astronaut drinking water with harmful microorganisms. Concerns have arisen over existing biocides — that they’re inadequately effective, and may have toxic side effects when consumed. New microbial control methods are a priority. This need is addressed by using an electrochemical reactor for on-demand generation of hydrogen peroxide (H2O2) solutions. The device uses onboard resources only. The method eliminates the need for resupply items (reducing launch costs), and reduces toxicity risk.
