Moriarty, New Mexico – September 15, 2026 -- Sceye's ST1 high-altitude platform station (HAPS) completed a nearly 30,000-km round trip between New Mexico and Japan, returning to continental US airspace on September 4, 2026, and reaching its Moriarty headquarters airspace on September 5, 2026, for additional testing and a planned descent.

ST1 marks Sceye's first flight to Asia under a SoftBank partnership

The mission, conducted in partnership with Japanese telecom operator SoftBank Corp. (TOKYO: 9434), represented Sceye's first flight into Asia and a milestone toward commercial deployment of HAPS as stratospheric infrastructure. The platform carried a SceyeCELL module, described as a first-of-its-kind 'cell tower in the sky' designed to deliver broadband mobile access from the stratosphere directly to standard devices across wide areas. Sceye states a fully deployed HAPS platform can cover an area equivalent to roughly 500 ground-based cell towers.

The high-altitude platform station (HAPS), developed with SoftBank Corp. (TOKYO: 9434), marked Sceye's first flight into Asia and a key step toward commercial HAPS deployment. ST1 maintained a station-keeping radius of just 5 kilometers off the Japanese coast while operating continuously at 16.5 to 17 kilometers altitude.

Tokyo – September 07, 2026 -- Sceye's high-altitude platform system flew more than 15,000 km through the stratosphere from New Mexico to Japan in 13 days, marking the company's first flight to Asia and a milestone toward commercial deployment of stratospheric telecom infrastructure.

The Service Test 1 (ST1) mission launched August 9, 2026 at 7:00 a.m. Mountain Daylight Time from New Mexico and spent over seven days operating in airspace controlled by Japan, executed in partnership with SoftBank Corp. (Tokyo: 9434).

Platform delivers mobile broadband to unmodified devices via SoftBank's core network

Upon reaching Japanese airspace, ST1 demonstrated mobile broadband connectivity to standard devices through SoftBank's core network, including text messaging, voice calls, internet access and video streaming. The tests also covered emergency alert broadcasting for large-scale disaster scenarios and drone communications.
