As deep-sea waters warm, scientists expected trouble for the microbes that help keep ocean chemistry in balance. Instead, researchers found that Nitrosopumilus maritimus can adapt to warmer, iron-limited conditions by using iron more efficiently. Because these microbes control key nitrogen reactions that support marine life, their adaptability could help sustainContinue Reading

Single-aisle Turboelectric Aircraft with Aft Boundary-Layer Propulsion A key priority for NASA Aeronautics is investing in electrified aircraft propulsion (EAP) technologies for their potential to reduce fuel consumption, emissions, and noise for commercial airplanes. Achieving these benefits could be a key step towards environmental sustainability for the entire aviation industry.Continue Reading

PEGASUS In the last decade, airlines have shifted their focus from capturing market share to consolidating operations along the most profitable routes. Airlines have also increased the average load factor of flights and have shifted from under-50 seat regional aircraft toward 70-90 seat aircraft, which tend to have superior operatingContinue Reading

X-57 Maxwell NASA’s X-57 Maxwell was an all-electric experimental aircraft designed to demonstrate multiple cutting-edge technologies. The goal of the X-57 was to demonstrate that an all-electric airplane can be more efficient, quieter, and more environmentally friendly than airplanes powered by traditional gas piston-engines. The X-57 sought to demonstrate theContinue Reading

Risk Assessment for Unmanned Aircraft Systems (UAS) Commercial use of small unmanned aircraft systems (UAS) is expected to grow significantly in the coming years due to the vehicles anticipated benefits. Several private industries have proposed using UAS to transport goods while others have considered using the aircrafts to support newsContinue Reading

Safe2Ditch Safe2Ditch was an autonomous crash management system designed to run on a small processor onboard unmanned aerial vehicles (UAVs). Designed to be inexpensive and light, the technology takes advantage of components that are already part of many small UAV systems such as visual spectrum cameras and commercial off-the-shelf (COTS)Continue Reading

Quesst Mission All four of NASA research centers and Lockheed Martin Skunk Works are on a mission to build the X-59 – the first quiet supersonic research aircraft. Stemming from low-boom flight research that had its roots in ASAB for decades, NASA Langley and SACD have been instrumental in theContinue Reading
