Datacasting V3.0 provides an RSS-based feed mechanism for publishing the availability of Earth science data records in real time. It also provides a utility for subscribing to these feeds and sifting through all the items in an automatic manner to identify and download the data records that are required for a specific application.

A high-speed data recorder and replay equipment has been developed for reliable high-data-rate recording to disk media. It solves problems with slow or faulty disks, multiple disk insertions, high-altitude operation, reliable performance using COTS hardware,...

There are eight herpes viruses that infect humans, causing a wide range of diseases resulting in considerable morbidity and associated costs. Varicella zoster virus (VZV) is a human herpes virus that causes chickenpox in children and shingles in adults. Approximately 1,000,000 new cases of...

The conventional method for integrating a radiometer into radar hardware is to share the RF front end between the instruments, and to have separate IF receivers that take data at separate times. Alternatively, the radar and radiometer...

There is a need to acquire autonomously cryogenic hydrocarbon liquid sample from remote planetary locations such as the lakes of Titan for instruments such as mass spectrometers. There are several problems that had to be solved relative to collecting the right amount of...

As remote sensing for scientific purposes has transitioned from an experimental technology to an operational one, the selection of instruments has become more coordinated, so that the scientific community can exploit complementary measurements. However, technological and scientific heterogeneity across devices...

A document discusses the CCD97 from e2v technologies as it is being evaluated at Goddard Space Flight Center’s Detector Characterization Laboratory (DCL) for possible use in ultra-low background noise space astronomy applications, such as Terrestrial Planet Finder Coronagraph...

Carnegie Mellon University has developed a method for tracking the locations of multiple individuals in complex, indoor settings using a network of video cameras. The method was able to automatically follow the movements of 13 people within a nursing home, even though individuals sometimes...

NASA is one of the top research entities in the world, producing technologies that range from electronics and new materials, to state-of-the-art robotics and sensors. Readers of NASA Tech Briefs get a firsthand look at these new technologies every month. But how many of you have had the chance to go behind the scenes at...

Carbon nanotubes and magnetic molecules are considered building blocks of future nanoelectronic systems. Researchers of Karlsruhe Institute of Technology and French colleagues have combined both components on the atomic level and to build a quantum mechanical system with novel properties.

U.S. Army Research Laboratory scientists in the Sensors and Electron Devices Directorate are currently exploring the field of quantum sensing and are discovering ways in which the Army can benefit from innovations that were once thought impossible.

Scientists from the University of Lincoln and Newcastle University in the U.K. have created a computerized system that allows for autonomous navigation of mobile robots based on the locust’s unique visual system. The work could provide the blueprint for the development of highly...
