Спутник технологический. Perseus 000. [Редактировать]

Национальное управление военно-космической разведки США (National Reconnaissance Office, NRO) в 2009 году в рамках программы Colony-1 (the Weather Colony Program) заказало у Лос Аламосской национальная лаборатории четыре КА Perseus (CubeSat 1.5 U, 1.5 кг) для проверки перспективных технологий в интересах разведки наземных и космических целей. Все КА запущены в декабре 2010 года.
