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.

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.

Gas Flow Measurement Technology Packs Hundreds of Sensors Into One Optical Fiber

By fusing together the concepts of active fiber sensors and high-temperature fiber sensors, a team of researchers at the University of Pittsburgh has created an all-optical high-temperature sensor for gas flow measurements that operates at record-setting temperatures above 800 °C. This technology is expected to find industrial sensing applications in harsh environments ranging from deep geothermal drill cores to the interiors of nuclear reactors to the cold vacuum of space missions, and it may eventually be extended to many others.

The Road to Lightweight Vehicles

With a steady rise in fuel prices and increasing restrictions on emissions, automakers face difficult challenges as they are forced to find ways of making their cars lighter and more fuel-efficient. One way to achieve this goal is to incorporate strong, lightweight, and durable composite materials to replace heavier, more energy-hungry materials.
