Pioneering the Stratosphere
Urban Sky is pioneering humanity's routine and easy access to the stratosphere and the value locked within it.
Unlocking the Stratosphere
The stratosphere—the layer of atmosphere between 40,000 and 130,000 feet— represents one of Earth's last untapped resources. It offers unique advantages for surveillance, communications, and scientific research, but has remained largely inaccessible due to technical and economic barriers.
Urban Sky is changing that. Our patented Microballoon technology enables affordable, repeatable access to this critical domain, opening new possibilities for defense, commercial, and scientific applications.
