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

Alen Space has completed the first demonstrator pilot campaign of VDES technology using its SATMAR satellite over the Bay of Algeciras in southern Spain. Over the past week, the company worked with Egatel and the Port Authority of the Bay of Algeciras to run several operational tests in a real maritime setting. In the first pilot, SATMAR supported message exchanges between a vessel and the

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 multinational research team led by UiT The Arctic University of Norway has identified the deepest known gas hydrate cold seep on Earth during the Ocean Census Arctic Deep - EXTREME24 expedition, documenting the Freya Hydrate Mounds at 3,640 meters depth on the Molloy Ridge in the Greenland Sea. The work reveals a previously unknown ecosystem on the Arctic seafloor where exposed gas hydrate, me

North Korean leader Kim Jong Un oversaw the test-firing of "cutting-edge" hypersonic missiles to ready Pyongyang's nuclear forces for war, state media said Monday. Pyongyang said Sunday's test was made all the more necessary by "recent geopolitical crisis" - a clear nod to this weekend's events in North Korea's socialist ally Venezuela. Seoul and Tokyo said Sunday they had detected the

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

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
