Launch Milestone and Mission Details
A Falcon 9 rocket lifted off from Cape Canaveral Space Force Station on a Sunday afternoon at 2:49 p.m. EDT, carrying the final three satellites for Luxembourg-based SES’s O3b mPOWER network. The flight marked SpaceX’s 700th Falcon launch overall—687 Falcon 9 missions and 13 Falcon Heavy missions—and was the company’s 107th orbital launch of the year. The first-stage booster, tail number B1080, completed its 29th flight and landed on the “A Shortfall of Gravitas” droneship in the Atlantic Ocean. The upper stage deployed the three satellites to medium Earth orbit (MEO) roughly 34 minutes after liftoff, with deployments staggered by seven minutes.
Constellation Background and Technical Specs
SES’s O3b mPOWER system is designed for low-latency, high-throughput communications in MEO, supporting commercial, government, and military users. Prior launches between December 2022 and July 2025 placed ten satellites in orbit; the September 2026 launch brings the total to 13. The satellites were built by Boeing. Space.com reported each spacecraft weighs about 3,750 pounds (1,700 kg), while Spaceflightnow cited a dry mass of 1,900 kg, indicating a discrepancy in reported mass figures.

- “The fully operational O3b mPOWER constellation proves the effectiveness of our software-defined payload technologies, shown by our ability to secure the most demanding missions of our commercial, joint-force and allied military customers,” — Ryan Reid, president of Boeing Satellite Systems International
Future Outlook
Boeing expects the new satellites to enter service by mid-2027 after orbit-raising maneuvers, checkouts, and commissioning are completed, expanding the constellation’s capacity for both commercial and defense customers.
