Photonics
Photonics is the branch of science and technology that deals with the properties and applications of photons, the fundamental particles of light. In the context of space and astronautical engineering, photonics plays a crucial role in the development of advanced optical systems for communication, sensing, and imaging. Photonics-based technologies are used in space-based telescopes, laser communication systems, lidar sensors for planetary exploration, and optical instruments for remote sensing of the Earth's atmosphere and surface. Photonics also enables the development of high-speed data transmission systems for space-based applications, which are essential for the efficient transfer of large amounts of data between spacecraft and ground stations. Furthermore, photonics-based technologies are used in the development of advanced propulsion systems, such as laser propulsion and solar sails, which rely on the momentum transfer of photons to generate thrust.
