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.

2015 Create the Future Design Contest: Sustainable Technologies Category Winner

ECHY: Solar Lighting with Fiber Optics Stephanie Le Beuze ECHY Ile-de-France, France“As we are a French start-up that is relatively unknown outside of Europe, winning an award of this kind will definitely help us make an entry into the international market. The recognition of this award will enable us to approach the US market with more confidence, so that we can collaborate with architects, designers, and engineers to bring ECHY and our daylight technology across the ocean!”For many, artificial light has completely replaced natural light. Lighting can account for up to 50% of building electricity consumption, and up to 56% of energy bills in offices. Artificial light is not only costly for us and for the environment, but prevents us from using a natural and abundant resource: sunlight.

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

This technology can be used in wastewater treatment plants. 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.

Autonomous Robots Keep Warehouse Running Green

YLOG, a startup company in Austria, uses an intelligent and very environmentally friendly logistics system that is winning an increasing number of customers. The technology makes use of individual, freely moving Autonomous Intelligent Vehicles (AiVs) that detect each other, observe right-of-way rules, recognize one-way routes, and complete their tasks fully autonomously without intervention from or coordination by a central computer.

High-Performance Photocatalytic Oxidation Reactor System

Airborne volatile organic chemicals are oxidized using blue LEDs, fiber optics, and visible light-activated catalysts for space and terrestrial air purification. Marshall Space Flight Center, Alabama As crewed space missions extend beyond low Earth orbit, the need to reliably recover potable water is critical. Aboard the International Space Station (ISS), the water is recycled from cabin humidity condensate, urine distillate, and hygiene wash wastes. In spacecraft cabin air environments, off-gassing from equipment, human metabolism, and human personal care products contributes to significant airborne concentrations of volatile organic compounds (VOCs). These polar and water-soluble compounds ultimately dissolve into the humidity condensate and stress the process load, logistics costs, and lifecycle requirements of the water processing systems. The aim of this effort was to develop the High Performance Photocatalytic Oxidation Reactor System (HPPORS) technology for the destruction of airborne VOCs prior to reaching the water processing systems. This innovation will reduce the logistics costs and lifecycle requirements of water processing systems, and help extend NASA missions to include long-duration space habitation and lunar and Mars colonization missions.
