Спутник технологический. GRIFEX. [Редактировать]

GRIFEX (GEO-CAPE ROIC In-Flight Performance Experiment) это технологический спутник на основе платформы 3U CubeSat который должен помочь НАСА с отработкой технологии быстрой съемки. Успешная отработка тхнологии позволит НАСА создавать гидрометеорологические аппараты с высокой скоростью работы.
