• ‘QIMINGXING 50’ is China’s first fully solar-powered unmanned aerial vehicle (UAV) that has successfully completed its maiden test flight.
  • It is the first large-sized UAV powered only by solar energy.
• According to Chinese media reports, the drone took a smooth flight for 26 minutes and landed safely.
• It is a high-altitude, long-endurance (HALE) UAV that can stay airborne for long durations.
• The drone flies above 20-km altitude where there is stable airflow with no clouds. This helps the drones to make maximum use of solar equipment to stay functional for extended durations.
• The drone can operate from 20 km to 100 km above the Earth’s surface; this makes it capable of carrying out satellite-like functions.
  • These drones are also called ‘High Altitude Platform Stations’ or pseudo-satellites.
• These drones can undertake surveillance missions that require them to stay operational, watching over borders or oceans, for months.
• These Drones are cost-effective to build and are also easy to launch and operate.
