IR

IR stands for Infrared Radiation. In space and astronautical engineering, IR is a type of electromagnetic radiation that has a longer wavelength than visible light. IR is used in various applications such as thermal imaging, remote sensing, and communication. In thermal imaging, IR is used to detect and measure the temperature of objects and surfaces. In remote sensing, IR is used to gather information about the Earth's surface and atmosphere. In communication, IR is used for short-range wireless communication between spacecraft and for data transmission between ground stations and spacecraft. IR is also used in the design of spacecraft and space suits to regulate temperature and prevent overheating.
