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.

Habitat Water Wall for Water, Solids, and Atmosphere Recycle and Reuse

This technology can be used in wastewater treatment plants. Ames Research Center, Moffett Field, California A method was developed that allows water recycling, air treatment, thermal control, and solid residuals treatment and recycle to be removed from the usable habitat volume and placed in the walls of a radiation-shielding water wall. This design also provides a mechanism to recover and reuse water treatment (solid) residuals to strengthen the habitat shell.
