Abstract: In this paper,the satellite test results of the fused silicasecondary surface mirror (OSR) developed by Lanzhou Institute of Physicshave been reported,and the long-term space stability of OSR has beenestimated.the results of the test and the calculation showed that the 10-yearvariation of solar absorptance of OSR is below 0.05,with the same levelas the foreign products.It can meet the demand of satellite application.
