	+ GRC Home + GRC Facilities Home SMiRF has supported insulation performance tests for the X–33 vehicle and demonstration of a zero boiloff long-term cryogenic storage concept for the Mars Exploration Program.		The SMiRF vacuum chamber can accommodate test articles as large as 71 in. in diameter by 90 in.high. A programmable thermal shroud system can be used inside the SMiRF chamber to control background temperatures over a temperature range of 200 to 650 °R. Test article size is limited to 44 in. in diameter by 65 in. high when the shroud is installed. The SMiRF chamber can maintain a vacuum environment of 8.5x10-6 torr. The chamber can be evacuated along the Space Shuttle Pressure Ascent profile. Various purge gases are available onsite (GHe and GN2). The facility has also handled GH2 and G02 tests. Up to 512 channels of data can be collected at a nominal rate of 1/s. Data is collected and processed by a dedicated workstation computer and is archived on Glenn's central computer.
