- Additional information
- This paper reports a newly developed methodology combining mechanical and spectral measurements with principal components analysis to determine the lifetime of composites deployed in low Earth orbit (LEO), exposed to atomic oxygen. New polymer blends (developed in Bristol), screened using this technique, will be tested in LEO microsatellite mission (150-200kg bus) with expected 2021 launch. They have also been selected by ESA for testing on the International Space Station in 2022 (value of programme 4M Euro). The size of the deployable antenna market is £1.5B; OSS is targeting £60M in the Earth Observation, Internet of Things and Data Relay markets.
