The Cygnus XL cargo spacecraft, with its prominent cymbal-shaped UltraFlex solar arrays, departs the International Space Station after its release from the Canadarm2 robotic arm. NASA+ At 7:06 a.m. EDT, Northrop Grumman’s Cygnus XL was released from the Canadarm2 robotic arm, which earlier detached the cargo spacecraft from the Earth-facingContinue Reading
Northrop Grumman’s Cygnus XL cargo craft is pictured in the grips of the Canadarm2 robotic arm following its capture on Sept. 18, 2025. Cygnus XL is Northrop Grumman’s expanded version of its previous Cygnus cargo craft increasing its payload capacity and pressurized cargo volume. NASA Live coverage of the departureContinue Reading
As Brent crude approaches $100 a barrel, clean energy advocates say the Hormuz crisis is the latest proof that fossil fuel dependence leaves consumers at the mercy of distant wars.

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
