Video: HiSentinal is the airship-in-a-box which can float 13 miles above Earth

Southwest Research Institute is developing and flight testing HiSentinel, a tactical airship-in-a-box that is partially inflated on the ground and fully inflated only when it reaches float altitude 13 or so miles above the Earth's surface. This affordable, expendable, solar-powered airship is designed to autonomously carry various payloads and instrumentation aloft for 30 days or longer, providing an unblinking eye in the sky for military or scientific missions.
