Infrared Radiation
Infrared radiation (IR) is a type of electromagnetic radiation with longer wavelengths than those of visible light. In the context of space and astronautical engineering, IR is used for various purposes such as remote sensing, thermal imaging, and communication. IR sensors are used to detect and measure the temperature of objects and surfaces in space, which is crucial for monitoring the health of spacecraft and equipment. Thermal imaging using IR radiation is used to detect and locate heat sources, which can be used for various applications such as detecting fires, monitoring volcanic activity, and identifying energy leaks in buildings. In addition, IR communication is used for long-range communication between spacecraft and ground stations, as well as for inter-satellite communication.
