Abstract

Since the dawn of space exploration, material outgassing has been a major concern when developing a spacecraft. This has not only led to the creation of clean-rooms, but also to the development of various testing methods and standards used to understand the outgassing characteristics of any given material. In industry, low-outgassing materials are used to prevent contamination of electronics and camera lenses, because outgassed contaminates can lead to electronic failure and blurry images. The objective of this study is to develop a gas sensing sensor data acquisition system comprised of inexpensive commercial off-the-shelf components capable of detecting acceleration, atmospheric characteristics, and gas concentrations. Ground tests have been conducted to determine baseline characteristics of the components and develop an understanding of the CO2, CO and NO2 sensors’ ability to detect outgassing from PLA and ABS. Significant CO2 outgassing from PLA and ABS was observed, while CO outgassing was highly temperature dependent.
