Extreme thermal shock in space exploration poses a critical threat to orbital spacecraft, as conventional thermal protection structures cannot concurrently resist concentrated thermal effects under shock and ensure efficient heat dissipation during routine operation....
In low-altitude complex environments, accurately reconstructing the three-dimensional (3D) flight trajectories of small unmanned aerial vehicles (UAV) without onboard positioning modules remains challenging. To address this issue, this paper proposes a multi-view...
Très gênée sur le front ukrainien par l’absence d’un système de communication offrant haut débit et chiffrement incassable, l’armée russe place ses espoirs dans Rassvet, une constellation qui ne sera pas opérationnelle avant deux ans. La Russie a commencé le...
Optical materials power the magic of modern photonics, from smartphone cameras to global fiber-optic networks, by precisely shaping light’s transmission, reflection, absorption, refraction, and emission in lasers, sensors, and beyond. Selecting the right optical...
Groundbreaking research is underway at Northrop Grumman’s Microelectronics Center (NGMC) which is reshaping physicists’ understanding of diamonds, positioning them as the next-generation material used in manufacturing microelectronics. Today, successful tests are...
l y a quelques jours, dans le cadre de son partenariat conclu avec l’américain Kratos en 2025, Airbus Defence & Space a fait savoir qu’il était en train de préparer le premier vol d’un drone de combat collaboratif [CCA] XQ-58 «Valkyrie» équipé de son système de...
