美国和俄罗斯近年来都进行了多种空间环境对材料影响的飞行试验。主要的例子是长期暴露设施，该设施从1984年4月至1990年1月在低地球轨道上运行了5年零9个月，以及可拆卸盒式容器实验，该实验从1990年1月11日至1991年4月26日在和平号轨道站上飞行。通过比较环境暴露条件、热控涂层材料的功能和化学性质以及飞行前和飞行后对吸收率、发射率和原子氧侵蚀造成的质量损失的分析，对这两项任务产生的热控涂层材料数据进行了评估。美国和俄罗斯的空间环境测量和模型存在着明显的差异，这使得环境比较变得复杂。然而，两次飞行试验的结果都证实，氧化锌和氧化锌原钛酸盐白色热控涂料在偏硅酸盐粘合剂中暴露于这种空间环境时最稳定。俄罗斯的飞行材料经验扩大到使用硅树脂和丙烯酸树脂粘合剂，而美国则更多地依赖聚氨酯。
Both the United States and Russia have conducted a variety of space environment effects on materials flight experiments in recent years. Prime examples are the long duration exposure facility, which spent 5 years and 9 months in low Earth orbit from April 1984 to January 1990, and the removable cassette container experiment, which was flown on the Mir orbital station from Jan. 11, 1990 to April 26, 1991. Thermal control coating materials data generated by these two missions are evaluated by comparing environmental exposure conditions, functionality and chemistry of thermal control coating materials, and preand postflight analysis of absorptance, emittance, and mass loss due to atomic oxygen erosion. These are noticeable differences in the United States and Russian space environment measurements and models, which complicates comparisons of environments. Nevertheless, the results of both flight experiments confirm that zinc oxide and zinc oxide orthotitanate white thermal control paints in metasilicate binders are the most stable upon exposure to this space environment. Russian flight materials experience broadens to the use of silicone and acrylic resin binders whereas the United States relies more heavily on polyurethane.
