Space operations of the National Aeronautics and Space Administration (NASA) flying to solar system objects must be able to sustain life, or may sustain life in a fundamentally evolved state, with strict restrictions on the maximum number of spores on the surface of the spacecraft; As the efficiency of the procedures increases, these levels of restriction are likely to decrease slowly. Of course, the clean room requirements of other aviation types are basically the same.

Aerospace Cleanroom Requirements:

At present, the highest level is the aerospace aviation aerospace warehouse, which belongs to level 1 and belongs to a special field with a relatively small area. Microbial barriers can be used to prevent previously contaminated areas from being repeatedly contaminated; at least 1,244 Pa (5 inches of water) can be used to prevent microbial intrusion. HEPA (0.3μm, efficiency ≥99.97%) is also a recognized high-efficiency microbial barrier.

Mars landing spacecraft cabin requirements:

For a Mars landing mission, the maximum number of spores allowed for the entire spacecraft is 300,000 (or <300 bacterial spores/m2); all other targets still have a slope stability probability requirement. Each surface area of each spacecraft can have 300,000 spores for non-special areas of Mars (most surfaces), and the total allowable amount of organisms (such as cans) in the hardware is 500,000.

Aviation clean room clean instructions:

Most aerospace cleanrooms have unknown microbial deposition rates and surface microbial populations. There are generally no microbiology laboratories that can be put into use immediately. When constructing a suitable microbiology laboratory to implement NPR5340.1, the PP procedure must first The job is to make the clean room as sterile as possible, so a temporary lab can be built, using a Class 100 clean bench and a benchtop thermostat. Preliminary testing of clean rooms and related equipment can be accomplished using commercially available settling plates and trypsin soy agar based contact plates. These programs are primarily designed to detect and calculate the number of bacterium, mesophilic, aerobic, and anaerobic microorganisms. Microorganisms that survive as much as possible in space and planetary environments have salt-loving organisms, and certain species of Bacillus And extreme microbes.
