Supercritical CO2 Cleaning for planetary protection and contamination control

Abstract

We have designed and built a new Supercritical CO2 Cleaning (SCC) system1,2 to conduct cleaning efficiency studies using Supercritical CO2 and liquid CO2 to remove trace amounts of microbial and organic contaminants from spacecraft material surfaces. The objective of this task is to develop an effective CO2 cleaning method and to demonstrate and validate… (More)
