Solar Radiation Spectrum

This lecture covers the solar radiation spectrum, including the spectral irradiance at different wavelengths, solar flux in the solar system, variations in the Solar Constant, and the impact of solar UV radiation. It also delves into Earth's energy budget, the concept of a blackbody spectrum, and the radiation balance for spacecraft. The presentation explores the properties of materials in space, spacecraft design strategies, orbital lifetime, and the challenges posed by space debris. Additionally, it discusses the threats posed by asteroids and comets, past impact events, and potential solutions to the space debris problem.
