This material is based upon work supported by NASA under Contract NNM10AA11C issued through the New Frontiers Program. The successful use of microporous PTFE flexible thin sheets was brought about by the government and industry team work. The authors acknowledge the following individuals for their excellent work in installing the microporous PTFE flexible thin sheets to the flight hardware: Christian May and Jeremy Bennington of Lockheed Martin Space System Company. The authors also thank the following individuals for their technical contributions during the development phase: David Everett and Gary Davis of the GSFC Mission Systems Engineering Branch; Charles Lorentson, Griffin Jayne, and Lon Kauder of the GSFC Contamination and Coatings Engineering Branch; Christian May and Jeremy Bennington of Lockheed Martin Space System Company. Berghof Fluoroplastic Technology GmbH supplied the microporous black PTFE flexible thin sheet, and Porex Corporation supplied the microporous white PTFE flexible thin sheet. Their assistance to deliver their products on time to meet the extremely tight flight qualification and testing schedule at GSFC is much appreciated.

N2 - Microporous black polytetrafluoroethylene (PTFE) flexible thin sheets are successfully flown as solar diffusers on NASA’s Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) spacecraft. They serve as multilayer insulation (MLI) blanket outer covers for the arm of the Touch And Go Sample Acquisition Mechanism (TAGSAM), the sunshade of the OSIRIS-REx Camera Suite (OCAMS) PolyCam imager, and the motor riser of the OCAMS SamCam imager. Additionally, microporous white PTFE flexible thin sheets are successfully flown as a MLI blanket outer cover with a low ratio of absorptance to emittance for the Regolith X-ray Imaging Spectrometer (REXIS). For ground testing, microporous black and white PTFE flexible thin sheets were successfully used as optical targets of the Touch And Go Camera System (TAGCAMS) NavCam imagers in the flight system thermal vacuum test.
