External Tank Moisture Control Area(s) of Significant Benefit Safety Performance Sustainability Operations Infrastructure • Description • Develop a heating process to control moisture trapped within and behind the External Tank (ET) insulation. • Test the effectiveness of using heat to control moisture buildup at the insulation • Develop necessary Ground Support Equipment (GSE) to implement the selected procedure • Work with the ET manufacturer and designers to qualify this procedure. • Technologies and Capabilities • Heating is a common technique to prevent moisture buildup within cavities • The temperatures associated with this technique are a few degrees above the dew point and do not create a safety concern • Some concepts have no weight penalties Benefits and Impacts Obsolescence Reduction Risk Reduction Safety Improvement Cost Reduction Process Improvement Other (Ultra-High Operations Improvement Reliability) Performance Enhancement • POC, Cost, Schedule and Maturity • TRL 5 ET Moisture Control: 004 • Heating is a mature process for removing moisture • POC: W. G. Harris (321) 861-8942 • Minimizes the ET insulation/moisture concerns without scrapping expensive flight hardware • May have minimal weight penalty • Reduction in Criticality 1 Failure Rate of .01%
