          CONTAMINANTS: SOURCES OF CONTAMINATION | 
     
     
	   | 
       
        Always keep in mind that particulate contamination
        is a real threat to the proper operation of spacecraft and instrumentation.
        Instances of contamination problems leading to performance failures are
        well documented, from the Skylab and Voyager missions of the 1970’s right
        up to the present. With the increasing complexity and sophistication
        of today’s variety of missions, the unique and special considerations
        of cleanroom operations and procedures is critical for the continued
        success of our space flight programs. |
