Researchers from Zhengzhou University, the University of Kent, and City University of Hong Kong have developed a framework to evaluate and optimize the spatiotemporal resilience of Internet of Things (IoT)-enabled unmanned system of systems operating in complex missions. The work responds to the growing use of unmanned aerial vehicles and unmanned vehicles in hazardous environments where maintai

The airliners of coming decades may feature long, slender wings that change the look of commercial aircraft while improving ride quality and cutting fuel use. Those high aspect ratio wings promise lower drag and better efficiency, but their increased flexibility introduces structural and control challenges that engineers must address before airlines can adopt them. As part of the Int

A recent study presents ACA-SIM, an atmospheric correction algorithm that uses satellite-in situ matchup data and neural networks to improve ocean color retrievals over coastal waters. The approach relies on real satellite radiance and in situ reflectance from Aerosol Robotic Network-Ocean Color (AERONET-OC) sites to reduce errors and striping artifacts in derived ocean color products, particula

Orbital launch activity set another annual record in 2025, although future growth may depend on factors different from those that fueled the recent surge.

A Spanish military communications satellite launched in October was struck by what its operator described as a “space particle,” an incident that could jeopardize the spacecraft’s mission.

SAN FRANCISCO – Eartheye Space will pool data from hundreds of Earth-observation satellites to provide imagery and data to a customer in the Asia-Pacific region.

From its perch on a rugged ridge in Gale Crater, NASA's Curiosity rover has stitched together a holiday postcard that doubles as a science panorama, framing the Nevado Sajama drill site against a hazy Martian sky. The scene merges two Mastcam mosaics taken on Nov. 18, 2025 - late afternoon on sol 4722 and early morning on sol 4723 - then tinted in cool blues and warm golds to emphasize changing

Simultaneous ground- and space-based observations of a newly discovered free-floating planet have enabled direct measurement of its mass and distance from Earth, according to a new study. The findings offer insights into the diverse and dynamic pathways by which planets can be cast adrift into interstellar space. Although studies to date have only revealed a handful of such free-floating p

On 17 December, two Galileo satellites lifted off from Europe's Spaceport in Kourou, French Guiana, aboard an Ariane 6 rocket, marking the 14th launch dedicated to Europe's Galileo constellation and reinforcing European satellite navigation capacity, resilience and autonomy. The spacecraft, designated SAT 33 and SAT 34, were launched at 06:01 CET and separated from the launcher after a fli
