Un internaute a découvert qu’un satellite de télécommunication Starlink de SpaceX est passé devant un satellite d’imagerie de la surface Terre pendant qu’il survolait le Texas. L’image a été retrouvée sur Google Earth. Que nous dit cet événement pas si anodin que cela ?

A quantum metasurface breakthrough boosts terahertz detection by 20 times, bringing practical THz technology a step closer. Detecting light and radiation is essential across the electromagnetic spectrum, but some regions remain difficult to work with. One of the biggest challenges involves terahertz (THz) radiation, which sits between microwaves and infrared light. Existing detectors for these [...]

NASA just demonstrated a technology that lets spacecraft communicate across multiple networks, paving the way for a more flexible and reliable space internet. NASA’s experimental Polylingual Experimental Terminal (PExT) has successfully completed its primary technology demonstration, marking an important step toward more flexible communications in space. Because the project met its original goals and continues [...]
