Time-expanded network model cuts complexity in mega constellation launch planning
Tuesday, 30 December 2025 06:17
Large Low Earth Orbit (LEO) constellations promise continuous, high-capacity information services, but planners must work within limits set by launch cadence, payload capacity, and orbital mechanics to deploy satellites in batches at reasonable cost. Researchers Junru Lin, Tiantian Zhang, and Min Hu at Space Engineering University in Beijing have developed an optimization framework that keeps de Space Themed Casino Games Slots, Rockets, and Astronaut Adventures

Conventional photon entanglement reveals thousands of hidden topologies in high dimensions
Monday, 29 December 2025 04:34
Researchers at the University of the Witwatersrand in South Africa, working with Huzhou University in China, have shown that a standard source of entangled photons used in quantum optics carries a rich set of hidden topological structures in high dimensions. They report entanglement across 48 dimensions with more than 17 000 distinct topological signatures, providing a large alphabet for encodin Japan's flagship H3 rocket fails to launch satellite
Monday, 29 December 2025 04:34
Japan's flagship H3 rocket failed to launch a geolocation satellite into orbit on Monday due to engine failure, the country's space agency said.
The second-stage engine "terminated prematurely" after the rocket blasted off at 10:51 am (0151 GMT) from the Tanegashima space centre in southern Japan, according to the Japan Aerospace Exploration Agency (JAXA).
It could not release into orbit Engineered interlayers boost satellite insulation and flexible electronics
Monday, 29 December 2025 04:34
Researchers at Empa are refining the multilayer insulation foils that wrap many satellites and space probes, aiming to improve their mechanical robustness while maintaining thermal protection. These foils, known as multilayer insulation or superinsulation, are built from stacked layers of a strong polymer coated with thin metal, typically aluminum, and are also used on Earth in items such as sur Synspective tapped to provide satellite imagery for Japan’s new military constellation
