Спутник технологический. MEMS Picosat. [Редактировать]

Миссия состоящая из двух аппаратов размером не более чем кредитная карта. Основной задачей системы являлась проверка возможностей системы космического аппарата OPAL и тестирование электронных компонентов. Масса каждого из аппаратов составляла около 200 грамм. В качестве полезной нагрузки аппаратов выступала коммуникационная полезная нагрузка.
