NASA Space Shuttle STS-2 Payload OSTA-1 Office of Space & Terrestrial Applications Pallet Patch. Patch is approximately 4" in diameter. From 1971 onwards, NASA managed applications missions independently from science missions, first through the Office of Applications and then, from 1977, through the Office of Space and Terrestrial Applications (OSTA). In November 1981, OSTA and the Office of Space Science merged into the Office of Space Science and Applications (OSSA). OSTA's objective was to “conduct research and development activities that demonstrate and transfer space-related technology, systems and other capabilities which can be effectively used for down-to-earth practical benefits.” It was divided into divisions for materials processing in space, communications and information systems, environmental observation, research observation, and technology transfer. This patch is from my personal collection from a smoke free and pet free home.Thank you for looking at my listing. Please see my other listings for more space patches and other items.
