HALE (High Altitude Long Endurance) UAVs and HAPS (High Altitude Pseudo-Satellites) are massive aircraft, often with wingspans as large as a Boeing 747, that rely on solar power to remain aloft for multiple weeks, or even months, at a time. The stratosphere, at an altitude of 20km, poses engineering challenges to aircraft due to its harsh conditions.
