Sceye airship completes New Mexico-Japan round trip in sky-cell-tower test
Sceye’s uncrewed stratospheric airship flew from New Mexico to Japan and back between August and September 2026, demonstrating a helium platform designed to station-keep near 60,000 feet and act as a cell tower in the sky, according to Ars Technica.
The trans-Pacific flight took place over a month and was the most notable milestone yet for Sceye, Ars Technica reported. It came nearly 100 years after the dirigible Graf Zeppelin made the first nonstop airship journey across the Pacific Ocean. Ars Technica reported that the point of the modern flight was less the distance than the purpose: testing how a stratospheric platform can hover over an area and support communications.
Sceye’s platform is filled with helium for buoyancy and equipped with an electric-powered propeller for active propulsion, allowing it to resist most strong winds and keep hovering over the same location for long periods, according to the report. It also uses top-mounted solar panels and onboard batteries to stay powered for stratospheric operations around the clock.
“We can stay over an area of operation, and we do that in the stratosphere right around 60,000 feet, so we're twice as high as air traffic and we're above the jet stream, and yet 30 times closer than low-Earth orbit satellites,” Mikkel Frandsen, founder and CEO of Sceye, told Ars Technica. “We can fly through day and night until the sun comes up the next morning and recharges the batteries, at which point we're still at the same altitude and still over the same area of operation.”
Ars Technica described the flight as a demonstration of how a lighter-than-air platform can serve as a cell tower in the sky. The platform is designed to operate in the stratosphere, above the jet stream and air traffic, while remaining far closer to the ground than low-Earth orbit satellites.
