Skydweller is a solar-powered drone that can fly for up to three months without landing, with researchers hoping to one day achieve much longer flight times. 

NASA is pushing the boundaries of aviation with its latest project: a solar-powered drone capable of remaining aloft for extended periods. Named Skydweller, this unmanned aerial vehicle (UAV) utilizes solar energy to power its systems, allowing it to fly continuously without the need for refueling.

The potential applications of such technology are vast. From providing persistent surveillance to enabling long-duration atmospheric research, Skydweller represents a significant advancement in UAV capabilities. Its ability to operate for months at a time could revolutionize how we approach tasks that require sustained aerial presence.

As research progresses, NASA aims to refine the technology to achieve even longer flight durations, potentially leading to the development of "eternal" aircraft that can operate indefinitely. This innovation could pave the way for a new generation of drones with unprecedented endurance and versatility.
