Carbon Dioxide
Carbon dioxide (CO2) is a colorless, odorless gas that is a natural component of the Earth's atmosphere. In the context of space and astronautical engineering, carbon dioxide is a critical consideration for life support systems. CO2 is produced by human respiration and must be removed from the air to maintain a breathable atmosphere. Additionally, CO2 is a byproduct of many industrial processes, including those used in spacecraft. Therefore, effective CO2 removal and management systems are essential for long-duration space missions. CO2 can also be used as a propellant in spacecraft propulsion systems, particularly in electric propulsion systems. However, the use of CO2 as a propellant requires careful consideration of the potential risks and challenges associated with handling and storing the gas in space.
