Chemical Sterilization


Chemical sterilization is a process of eliminating all forms of microbial life, including bacteria, viruses, fungi, and spores, using chemical agents. In the context of space and astronautical engineering, chemical sterilization is a critical step in ensuring the safety and success of space missions. It is used to decontaminate spacecraft, equipment, and surfaces to prevent the introduction of harmful microorganisms into space environments. Chemical sterilization methods include the use of gases, such as ethylene oxide and hydrogen peroxide, and liquids, such as formaldehyde and glutaraldehyde. These agents are highly effective in killing microorganisms but can also be hazardous to human health and the environment. Therefore, proper handling, storage, and disposal of chemical sterilants are essential to ensure safety. Chemical sterilization is a crucial aspect of planetary protection, which aims to prevent the contamination of other planets and moons with Earth's microorganisms during space exploration.
