LEDs

LEDs (Light Emitting Diodes) are semiconductor devices that emit light when an electric current is passed through them. In space and astronautical engineering, LEDs are commonly used for lighting purposes due to their low power consumption, long lifespan, and durability in harsh environments. LEDs are also used in optical communication systems, as they can be modulated at high frequencies to transmit data. Additionally, LEDs are used in spectroscopy to analyze the composition of planetary surfaces and atmospheres. In space exploration, LEDs have been used in various missions, such as the Mars Exploration Rovers and the International Space Station.
