Sceye

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.

Moriarty, New Mexico – September 15, 2026 -- Sceye's stratospheric platform ST1 has completed a nearly 30,000-kilometer round trip between New Mexico and Japan, re-entering continental U.S. airspace on September 4, 2026, and reaching the company's Moriarty headquarters the following day for final testing and controlled descent.

ST1 logged over seven days in Japanese controlled airspace during a month-long mission

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.

Moriarty, New Mexico – September 15, 2026 -- Sceye's ST1 high-altitude platform has completed a nearly 30,000-km round-trip mission between New Mexico and Japan, landing back near the company's Moriarty headquarters after re-entering continental U.S. airspace on September 4, 2026. The uncrewed stratospheric aircraft reached New Mexico airspace on September 5, 2026, where engineers ran final platform tests before executing a planned flight-termination and descent procedure.

Moriarty, New Mexico – September 13, 2026 -- Sceye's ST1 high-altitude platform completed a nearly 30,000 km round-trip flight from New Mexico to Japan and back, re-entering continental U.S. airspace on September 4, 2026 and reaching Moriarty, New Mexico on September 5, 2026, where the company conducted final vehicle testing and a planned descent.

The month-long mission was conducted with SoftBank Corp. (TOKYO: 9434) and represents Sceye's first flight into Asian airspace. ST1 carried SceyeCELL, described as a first-of-its-kind stratospheric "cell tower in the sky" built to deliver wide-area mobile broadband directly to standard devices. At full scale, one Sceye HAPS is designed to cover an area equivalent to roughly 500 terrestrial towers.

The month-long mission, conducted with Japanese telecom operator SoftBank Corp. (TOKYO: 9434), represents a commercial milestone for high-altitude platform station (HAPS) deployment. ST1 operated in Japanese airspace for more than seven days, maintaining continuous position over Japan's coast with a station-keeping radius of just 5 kilometers at altitudes between 16.5 and 17 km.

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.
