Deposition Sciences, Inc. (DSI), a wholly owned subsidiary of Lockheed Martin, specializes in advanced materials and optical coatings. For over 20 years, they’ve been producing their Sunshade® thermal control material, which is designed to provide reliable performance in extreme space environments.
DSI’s Sunshade® offered in both free film and tape versions. Both versions can withstand an atomic oxygen (AO) fluence greater than 1 × 1022 (AO/cm2). AO testing was performed concurrent with UV exposure to simulate survivability in 8 years of LEO. AO exposure testing showed negligible effect on Beginning of Life (BOL) and End of Life (EOL) performance.
