In August 2001 NASAs Glenn Research Centre began studying the technologies needed to build renewable electrical power systems for long-duration observation aircraft. The examined power management and distribution architectures for a coast-observing, stratospheric airship concept.
The inquiry that long-duration, coast-observing, stratospheric airships using renewable energy systems were feasible appropriate technology investments were made. Although feasible, such airships were not without many development challenges and airship size was strongly influenced by the seasons and coastal latitudes.
Wide-area surveillance for months at a time is presently impossible as neither satellites nor aircraft can provide these capabilities simultaneously. However, renewable energy technology enough to seriously consider building aircraft for ultra-long duration flights. In this arena, airships have significant potential. Airships, unlike aircraft, generate lift from buoyancy instead of through aerodynamics. Consequently, airships do not need to stay in motion to remain aloft. Therefore, they can stay over a specific location as well as move to a new location. In addition, airships can carry large-volume, heavy payloads. characteristics make airships superb candidates for long-endurance surveillance missions.
