Abstract:
The objective of the program is to design, fabricate, and test experimental flight packages capable of measuring the long term degradation of solar absorptance of thermal control coatings TCC in the space environment. Use of these highly accurate flight units will allow correlation of the performance of experimental TCC in the actual space environment with that exhibited in laboratory in situ simulated space environments. Six experiment packages capable of testing eight TCC surfaces each on an orbiting spacecraft have been developed. Each package weighs 430 grams, consumes 350 mw of power, operates from 28 plus or minus 5V, and provides a 0-5 V telemetry output with an overall accuracy of plus or minus 1F. A prototype flight unit successfully passed thermal cycling, shock, vibration and humidity test qualifications. Author
