Sunlight

Sunlight is the electromagnetic radiation emitted by the Sun, which is essential for life on Earth and plays a crucial role in space and astronautical engineering. Sunlight is composed of various wavelengths of radiation, including ultraviolet, visible, and infrared light. In space and astronautical engineering, sunlight is used for various purposes, such as powering solar panels on spacecraft and providing illumination for astronauts during spacewalks. Sunlight is also used for navigation, as it can be used to determine the position of a spacecraft relative to the Sun. However, sunlight can also pose a threat to spacecraft and astronauts, as it can cause damage to sensitive equipment and can cause radiation sickness in humans exposed to high levels of radiation.
