Clean Rooms
Clean rooms are specially designed and maintained environments with a low level of environmental pollutants such as dust, airborne microbes, aerosol particles, and chemical vapors. In the context of space and astronautical engineering, clean rooms are used for the assembly, integration, and testing of spacecraft, satellites, and other space-related hardware. The cleanliness level of a clean room is measured by the number of particles per cubic meter of air, and it is classified according to international standards. Clean rooms are equipped with specialized air filters, positive air pressure, and strict protocols for personnel attire and behavior to prevent contamination of the hardware. The use of clean rooms is critical to ensure the reliability and performance of space systems, as even a small particle or microbe can cause catastrophic failures in space.
