Arc Jet Complex Providing ground-based hyperthermal environments in support of the Nation?s Research & Development activities in Thermal Protection Materials, Vehicle Structures, Aerothermodynamics, and Hypersonic Entry. https://www.facebook.com/nasaames/videos/10154330812546394/ Benefit Innovative thermal protection materials and systems will be required to support NASA Exploration. Project missions, in particular crewed Moon or Mars return missions, will involve high velocity aerocapture or direct entry at Earth. These high stress missions will induce heating environments too severe for existing reusable Thermal Protection Systems (TPS). Qualifying a new TPS material for a crewed mission requires extensive testing to explore the limits of material performance, to validate reliability and repeatability of performance, to investigate the effects of material damage, and to develop a full database of material properties. Arc plasma facilities, operated by the Thermophysics Facilities Branch at NASA Ames, are critical to such a process, and to any other TPS developments required for Exploration missions, by providing the only ground-based simulation of flight entry conditions.
