Emissions
In the context of space and astronautical engineering, emissions refer to the release of gases, particles, and other substances into the atmosphere or space as a result of human activities. These emissions can have a significant impact on the environment and climate, as well as on the performance and safety of spacecraft and other space vehicles. Emissions from rocket engines, for example, can contribute to the depletion of the ozone layer and the formation of smog and other pollutants. In addition, emissions from spacecraft and satellites can interfere with radio and other communications, as well as with scientific observations and measurements. To mitigate the effects of emissions, space and astronautical engineers work to develop cleaner and more efficient propulsion systems, as well as to design spacecraft and other vehicles that minimize their impact on the environment and on other space-based activities.
