Greenhouse Gases
Greenhouse gases are gases that trap heat in the Earth's atmosphere and contribute to the greenhouse effect. These gases include carbon dioxide, methane, nitrous oxide, and fluorinated gases. In the context of space and astronautical engineering, greenhouse gases are a concern for spacecraft and planetary exploration. For example, the Mars atmosphere is primarily composed of carbon dioxide, which poses a challenge for human exploration and habitation. Additionally, spacecraft emissions can contribute to the buildup of greenhouse gases in the Earth's atmosphere, which can have negative impacts on the environment and climate. Therefore, space and astronautical engineers must consider the impact of greenhouse gases in their designs and operations.
