Sceye completes endurance testing for stratospheric internet balloons

Sceye's High-Altitude Platform System has finished its endurance testing program after more than 12 days aloft. The balloon-like devices aim to deliver internet from the stratosphere, bridging satellite and ground-based networks. Data from the tests will inform adjustments ahead of commercial flights.

Sceye's High-Altitude Platform Systems, or HAPS, are large oblong silver balloons that use helium for lift to reach and remain in the stratosphere. These platforms position themselves as an intermediate infrastructure layer between satellite services like Starlink and traditional cell tower internet. The technology also holds potential for environmental monitoring beyond connectivity. Sceye's latest test flight concluded the endurance program, with the HAPS airborne for over 12 days. During this time, the system collected data on performance degradation over extended periods. Company officials stated this information will enable necessary refinements. Looking ahead, Sceye plans commercial test flights focused on directing the platforms to targeted areas to supply ground-based internet. These efforts bring the technology closer to broader deployment as a competitor to satellite internet providers.

South Korea's Compact Advanced Satellite (CAS) 500-2 successfully launched from Vandenberg Space Force Base in California on a SpaceX Falcon 9 rocket. The satellite entered low-Earth orbit and made first contact with a ground station in Norway. The Korea AeroSpace Administration (KASA) confirmed it is operating normally.

NASA has contracted a startup to launch a robotic spacecraft that will grab the aging Swift observatory and raise its orbit before it falls too low. The Link servicing satellite is set to fly on the final Pegasus rocket later this month.
