Facebook recently completed its first test flight of a solar-powered drone that is designed to beam down internet access to remote areas of the world.

The Aquila drone is being developed to broaden the scope of internet connectivity around the globe. "New technologies like Aquila have the potential to bring access, voice and opportunity to billions of people around the world, and do so faster and more cost-effectively than has ever been possible before," Jay Parikh, global head of engineering and infrastructure at Facebook, wrote in a blog post about the project.

When testing is finished, the autonomous aircraft will be able to circle a region measuring up to 60 miles (96.6 kilometers) in diameter, while using laser communications and millimeter wave systems (extremely high-frequency radio waves) to send connectivity down from an altitude of more than 60,000 feet (18,288 meters).

The huge unmanned airplane has a wingspan larger than a Boeing 737 airliner, but weighs hundreds of times less (about one-third of an electric car), according to Facebook, because of its carbon-fiber frame. In fact, half of Aquila's mass is made up of batteries, which enable the solar-powered plane to fly during the day and night.

"Aquila is designed to be hyper efficient, so it can fly for up to three months at a time," Parikh wrote. "The aircraft has the wingspan of an airliner, but at cruising speed it will consume only 5,000 watts — the same amount as three hair dryers, or a high-end microwave."

The recent test flight was the first for the full-scale drone, as previous tests used a one-fifth scale version of Aquila, according to the social media giant. Facebook said it plans to push Aquila to the limits in a lengthy series of tests over the coming months and years.

During the low-altitude test flight, Aquila flew for more than 90 minutes, which was three times longer than Facebook had planned. The flight's success included performance verifications of the drone's aerodynamics, batteries, control systems and crew training.

"In our next tests, we will fly Aquila faster, higher and longer, eventually taking it above 60,000 feet," Parikh wrote. "Each test will help us learn and move faster toward our goal."

There is still a long road ahead as the social media company continues to test its internet-delivery drone.

The current world record for solar-powered unmanned flight stands at two weeks, set by by defense technology company Qinetiq's Zephyr plane in 2010, according to the Federation Aeronautique Internationale (FAI). To reach Aquila's goal of delivering internet connectivity for up to three months at a time, Facebook said it will require significant advancements in science and engineering.

"It will also require us to work closely with operators, governments and other partners to deploy these aircraft in the regions where they'll be most effective," Parikh said.
