What negative effect occurs when plastics and adhesives are exposed to the low-pressure vacuum of space?
Answer
Outgassing
Outgassing is the process where materials such as adhesives, plastics, or lubricants release trapped gases when they are exposed to the extremely low-pressure environment of a vacuum. This released gas can condense on and contaminate sensitive spacecraft hardware, such as solar arrays or optical instruments. Engineers must carefully select materials with low volatility to prevent this contamination from impacting mission performance.
