Спутник ДЗЗ. FSW 21. [Редактировать]

В официальном сообщении агентства Синьхуа приведена стандартная формулировка задач, решаемых спутниками серии FSW: «Спутник предназначен, главным образом, для научных исследований, картографирования и описания Земли, исследования космического пространства и других экспериментальных задач». Однако давно не является секретом, что основной задачей спутников серии FSW, периодически запускаемых с 1975 г., является картографическая съемка и видовая разведка в интересах Генерального штаба НОАК.
