Hurricane-Tracking Unmanned Systems Win NASA Challenge

NASA has selected three winning designs solicited to address the technological limitations of the uncrewed aerial systems (UAS) currently used to track and collect data on hurricanes. Engineering teams at Virginia Polytechnic Institute and State University, Purdue University, and the University of Virginia were named first- through third-place winners, respectively, of the agency's 2013-2014 University Aeronautics Engineering Design Challenge.

Agile Aperture Antenna Tested on Aircraft to Maintain Satellite Connection

Two of Georgia Tech's software-defined, electronically reconfigurable Agile Aperture Antennas (A3) were demonstrated in an aircraft during flight tests. The low-power devices can change beam directions in a thousandth of a second. One device, looking up, maintained a satellite data connection as the aircraft changed headings, banked and rolled, while the other antenna looked down to track electromagnetic emitters on the ground.

Heat-Sensing Camera Reveals Map of Mars Surface

A heat-sensing camera designed at Arizona State University has provided data to create the most detailed global map yet made of Martian surface properties.The map uses data from the Thermal Emission Imaging System (THEMIS), a nine-band visual and infrared camera on NASA’s Mars Odyssey orbiter. A version of the map optimized for scientific researchers is available at the U.S. Geological Survey (USGS)."We used more than 20,000 THEMIS nighttime temperature images to generate the highest resolution surface property map of Mars ever created," says the Geological Survey's Robin Fergason, who earned her doctorate at ASU in 2006. "Now these data are freely available to researchers and the public alike." SourceAlso: Read a Q&A with a Mars Science Laboratory (MSL) engineer.

Conformal Coatings Offer Reliable Protection for Advancing Technologies

Conformal coatings are used in the medical device, electronics, automotive, defense, and aerospace industries to protect components from their environments. As technologies continue to advance, often becoming smaller and more complex and/or utilizing advanced materials in their design, many conformal coatings struggle to provide reliable protection.

Economical Deployment of a Low Maintenance Asynchronous Health Monitoring System via Smart Energy Harvesting Instrumentation

Rocket engines and related hardware undergo extensive propulsion testing before being accepted into service. Ground propulsion testing can incur unexpected schedule delays and cost overruns due to untimely maintenance, repair, or replacement of unique valves. Efforts for monitoring the operational condition of the test facility valves drove the development of a novel Valve Health Monitoring System (VHMS).

New Study Uses Blizzard to Measure Wind Turbine Airflow

A study by researchers at the University of Minnesota using snow during a Minnesota blizzard is giving researchers new insight into the airflow around large wind turbines. This research is essential to improving wind energy efficiency, especially in wind farms where airflows from many large wind turbines interact with each other. As wind turbines have grown to more than 100 meters tall, field research in real-world settings has become more difficult.

NASA Completes Successful Test of Saucer-Shaped Vehicle for Mars Missions

NASA completed a near-space test flight of NASA's Low-Density Supersonic Decelerator (LDSD), developed to evaluate new landing technologies for future Mars missions. While this initial test was designed to determine the flying ability of the vehicle, it also deployed two new landing technologies as a bonus. Those landing technologies will be officially tested in the next two flights, involving clones of the saucer-shaped vehicle.
