Dynamic terrain model boosts airborne gamma ray survey accuracy
Monday, 23 February 2026 13:45
A research team led by Professor Hexi Wu and Dr Weicheng Li has developed a dynamic three dimensional terrain correction method that significantly improves the quantitative inversion accuracy of airborne gamma ray spectrometer surveys. The approach combines a novel sourceless efficiency calibration technique with a flight path based terrain model to tackle long standing challenges caused by over UNSW Canberra team advances iodine propulsion for satellites

Thousands of satellites are launched every year to support navigation, telecommunications, weather forecasting and emergency warning services, and most rely on onboard propulsion systems to manoeuvre once in orbit.
These propulsion systems are essential to change orbits, perform end of life de-orbiting, carry out collision avoidance with space debris or other satellites, maintain or adjust Warming drives growth of Arctic peatlands
Monday, 23 February 2026 13:45
New analysis shows that Arctic peatlands have expanded in recent decades as the region has warmed far faster than the global average. Average temperatures in the Arctic have risen by about 4 C over the last forty years, and the study links this rapid warming to the outward growth of peat-forming ecosystems.
Led by the University of Exeter, the research team examined peatland cores taken fr EU brings secure GOVSATCOM hub online under GMV leadership
Monday, 23 February 2026 13:45
The European Union has begun operational use of its 'Governmental Satellite Communications Programme', known as 'GOVSATCOM', opening secure encrypted satellite communications services to EU member states under European control. The move marks a significant step in the bloc's efforts to secure strategic autonomy in space-based communications for government and security users.
At the core of Texas AM partners with Aegis to orbit TAMU SPIRIT research hub on ISS
Monday, 23 February 2026 13:45
Texas A and M University has developed TAMU SPIRIT, a dedicated orbital research platform that will be deployed on the International Space Station in partnership with Aegis Aerospace. The platform will mount on the station's Express Logistics Carrier 3 and give Texas A and M System faculty, researchers and students sustained access to the conditions of low Earth orbit for a wide range of experim OpenAI hires creator of 'OpenClaw' AI agent tool
Monday, 23 February 2026 13:45
OpenAI has hired the Austrian creator of OpenClaw, an artificial intelligence tool able to execute real-world tasks, the US startup's head Sam Altman said on Sunday.
AI agent tool OpenClaw has fascinated - and spooked - the tech world since researcher Peter Steinberger built it in November to help organise his digital life.
A Reddit-like pseudo social network for OpenClaw agents called AAC Clyde Space adds Sedna satellites to boost maritime data services
Monday, 23 February 2026 13:45
AAC Clyde Space has started building two additional maritime data satellites, Sedna-3 and Sedna-4, to expand capacity in its established space-based maritime data services. The company has placed orders for key components and assigned the build to its U.S. subsidiary AAC SpaceQuest, aiming to support continuity of service and improve performance as its fleet renews Engineering Behind EarthDaily: Solving for Global Daily Coverage, Scientific Quality, and High-Spectral Diversity
