Energy Budget
Energy budget refers to the balance between the energy received by a spacecraft or a planet and the energy it emits or reflects back into space. In space and astronautical engineering, energy budget is an important concept as it determines the thermal environment of a spacecraft or a planet. The energy received by a spacecraft or a planet comes from various sources such as the sun, other celestial bodies, and internal heat sources. The energy emitted or reflected back into space is determined by the temperature and the emissivity of the surface. The energy budget is crucial in designing spacecraft and planetary missions as it affects the performance and the survivability of the spacecraft or the planet. Engineers need to carefully consider the energy budget of a spacecraft or a planet to ensure that it can withstand the extreme thermal conditions of space.
