Researchers from the National Physical Laboratory (NPL) are using femtosecond laser combs and optical imaging features on multiple spacecraft with the idea of creating one large detector that will enhance Earth observation and exploration of the universe. Their theory, that formation-flying spacecrafts could gather data in a way different from a standard spacecraft, might help determine the place from which all magnetic fields originate, answer the age-old question of how the universe developed after the big bang and ascertain whether Albert Einstein’s general theory of relativity is...Read full article

    detector
    1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
    positioning
    Positioning generally refers to the determination or identification of the location or placement of an object, person, or entity in a specific space or relative to a reference point. The term is used in various contexts, and the methods for positioning can vary depending on the application. Key aspects of positioning include: Spatial coordinates: Positioning often involves expressing the location of an object in terms of spatial coordinates. These coordinates may include dimensions such as...
