Orbital remote sensing provides a powerful way to efficiently survey targets for features of interest in inaccessible regions of the Earth as well as on other planets. One such feature of astrobiological relevance is the presence of surface sulfur deposits, which may...

The Spaceport Weather Data Archive provides a fully searchable database of weather data gathered at Kennedy Space Center and the Cape Canaveral Air Force Station. Weather data includes wind, temperature, and humidity data from a surface meteorological tower network; upper air soundings from both weather balloons...

Given a date range, the UAVSAR MySQL database is queried to evaluate data acquisition, processing status, and network performance, and uses the Google Charts API to dynamically return images of pie and bar charts to visualize processing and network statistics. The...

A software simulator was developed to simulate data flow from the Interface Data Processing Segment (IDPS) to the Science Data Segment (SDS) for the NPOESS Preparatory Project (NPP) via multiple Secure FTP (sftp) connections. The simulator is a multi-threaded Java program that handles the...

The recently launched Suomi National Polar-orbiting Partnership (SNPP) satellite, operated by NASA and the National Oceanic and Atmospheric Administration(NOAA), is providing multispectral global observations over the next several years to support a broad array of research and...

NASA seeks to preserve, and make readily accessible, historical Space Shuttle launch footage to inspire and educate NASA stakeholders both in and outside the NASA family through the dissemination of the Ascent production materials as a DVD, and through both NASA...

Combustion of realistic fuels is described by thousands of reactions involving thousands of species. Coupling these detailed chemical mechanisms with turbulence simulations is completely impractical because there is no computer powerful enough to solve the resulting equations.

Low-density parity-check (LDPC) codes often suffer from an “error floor” in which increasing signal-to-noise ratios do not lead to substantially better error rate performance. Error floors of LDPC codes are often not an inherent problem of the code design, but rather, a...

Nondestructive evaluation (NDE) method capability is determined by a statistical flaw detection study called probability of detection (POD) study. In many instances, the NDE flaw detectability is given as a flaw size such as crack length. The flaw is either a crack or behaving like a crack in terms of...

Liquid sprays are commonly used to inject fuels into combustion devices, making it important to study multicomponent (MC) two-phase flows in order to reveal their physics. “Multicomponent” is the terminology describing all fuels that are combinations...

This innovation creates observations of both targeted geographical regions of interest and general mapping observations, while respecting spacecraft constraints such as data volume, observation timing, visibility, lighting, season, and science priorities. This...

Laser Consult A novel technology investigates reservoir beds of oil, gas, freshwater, and thermal water deposits. The system, which uses electromagnetic frequency broadband sounding, gathers information to a depth of up to 7,000 meters. For effective operation on deposits, the technology draws up...

In two new papers, MIT researchers demonstrate the promise of printable robotic components that, when heated, automatically fold into prescribed three-dimensional configurations.One paper describes a system that takes a digital specification of a 3-D shape — such as a computer-aided design,...

A wireless system uses the same power as a cell phone to safely transmit energy to chips the size of a grain of rice. The technology paves the way for new "electroceutical" devices to treat illness or alleviate pain.The central discovery is an engineering breakthrough that creates a...

Using radio signals from satellite navigation systems, Scientists at Chalmers Department of Earth and Space Sciences have developed and tested a Global Navigation Satellite System (GNSS) tide gauge, an instrument that measures the sea level.The GNSS tide gauge uses radio signals from satellites in orbit...

Two new "cyberlearning" platforms allow non-artists to create illustrations rivaling the work of expert designers. The platforms sidestep a key creative barrier by eliminating the need for drawing skills in developing new designs. "Non-experts are becoming more empowered and interested in means...

GPS radio occultation measurements are vital for climate monitoring and atmospheric temperature change detection. However, the data are irregularly distributed in space and time, which makes it inconvenient for many applications.

The innovation provides enhanced health management routines for batteries. A mathematical model has been developed to describe battery behavior during individual discharge cycles, as well as over the cycle life. Different prognostic modes for estimating the state of charge, state of life, end of discharge,...

To reduce the cost of building specialized interfaces, missions can adopt Goddard Mission Services Evolution Center (GMSEC) technologies and applications. Assurances need to be made that application implementation should follow the GMSEC messaging standards. The GMSEC Interface...
