'Proximity Hat' Reveals Surroundings in Real Time

Karlsruhe Institute of Technology (KIT) researchers have developed a "Proximity Hat" that uses head pressure to inform users about their surroundings. The ultrasonic sensors, batteries, and pressure pads can be worn like a hat or headband.

New 3D-Printed Part Allows NASA to Measure Sea Ice

Slated for launch in 2018, NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will carry a 3D-printed part made of polyetherketoneketone (PEKK), a material that has never been used in additive manufacturing, let alone flown in space.

Gigantic Blades Could Generate More Offshore Energy

A new design for gigantic blades longer than two football fields could help bring offshore 50-megawatt (MW) wind turbines to the United States and the world. Sandia National Laboratories designed a low-cost, offshore, 50-MW turbine requiring a rotor blade more than 650 feet long, two and a half times longer than any existing wind blade. Most current U.S. wind turbines produce power in the 1- to 2-MW range, with blades about 165 feet long.

NASA Spacecraft Breaks Solar Power Distance Record

NASA's Juno mission to Jupiter broke the record to become humanity's most distant solar-powered emissary when Juno was about 493 million miles from the Sun. Launched in 2011, Juno is the first solar-powered spacecraft designed to operate at such a great distance from the Sun. That's why the surface area of solar panels required to generate adequate power is quite large. The four-ton Juno spacecraft carries three 30-foot-long solar arrays festooned with 18,698 individual solar cells.

NASA Maps Support Earthquake Relief Efforts

During natural disasters like high-magnitude earthquakes, areas most in need of assistance must be located as fast as possible. Researchers, led by Sang-Ho Yun at NASA's Jet Propulsion Laboratory, Pasadena, California, have developed a way to make maps of damage using the remote sensing technology of satellites. The method works even if the satellite images are taken at night or in cloudy skies.
