NASA Studies How Volcanic Ash Affects Airplane Engines

NASA researchers are poring over data from a recent test that involved sending volcanic ash through an airplane engine. The primary issue, according to NASA, is that volcanic ash forms glass in the hot sections of some engines that clogs cooling holes and chokes off flow within the engine, which can eventually lead to an engine power loss.

Remotely Piloted Plane Bridges Gap Between Wind Tunnel and Crewed Testing

A new modular, subscale remotely piloted aircraft offers NASA researchers more affordable options for developing a wide range of cutting edge aviation and space technologies. The Prototype-Technology Evaluation and Research Aircraft (PTERA) flying laboratory bridges the gap between wind tunnels and crewed flight testing.

Gamma-Ray Spectroscope Supports Asteroid Mining Missions

A new gamma-ray spectroscope detects the veins of gold, platinum, and rare earths hidden within the asteroids, moons, and other airless objects floating around the solar system. The sensor, developed by teams at Vanderbilt and Fisk Universities, NASA’s Jet Propulsion Laboratory, and the Planetary Science Institute, will allow miners to find valuable materials beyond Earth.

Sonic Tractor Beams Lift and Move Objects Using Sound Waves

Tractor beams are mysterious rays that can grab and lift objects. Now, researchers have built a working tractor beam that uses high-amplitude sound waves to generate an acoustic hologram that can pick up and move small objects.

Positioning Systems Improve Airport Logistics

Tow tractors, pushback tractors, tankers, luggage carts, air cargo, and catering vehicles crowd airport aprons. Poor weather conditions impede work on the apron even more. Researchers at the Fraunhofer Institute for Factory Operation and Automation IFF in Magdeburg are part of the EU project e-Airport, which is developing a positioning system that will increase safety on the apron. It will also make it possible to utilize airport capacities more efficiently because the system allows logistical operations to run in a significantly more structured way than before

Tiny Carbon-Capturing Motors Could Clean up Carbon Dioxide Pollution

Machines that are much smaller than the width of a human hair could one day help clean up carbon dioxide pollution in the oceans. Nanoengineers at the University of California, San Diego have designed enzyme-functionalized micromotors that rapidly zoom around in water, remove carbon dioxide, and convert it into a usable solid form.
