SES Completes O3b mPOWER Constellation with Final Three Satellite Launch

At exactly 2:49 pm local time on September 13, 2026, a SpaceX Falcon 9 roared away from Launch Complex 40 at Cape Canaveral, carrying SES’s eleventh, twelfth and thirteenth O3b mPOWER spacecraft. It was a moment that felt almost ceremonial – the last pieces of a puzzle falling into place.

“This launch marks a defining milestone for SES as we complete the O3b mPOWER constellation and further strengthen our MEO capabilities,” said Adel Al‑Saleh, SES’s chief executive. He went on to note that the new satellites reinforce the company’s promise to deliver “resilient, secure and scalable connectivity” for a growing roster of customers – from national governments to cloud providers and mobility operators.

The three freshly‑launched satellites join ten already‑operational O3b mPOWER units, together forming a medium‑Earth‑orbit (MEO) network that can beam anywhere from a few tens of megabits to several gigabits per second to a ground terminal. In practice, that means a remote research station in the Arctic, a fleet of autonomous ships in the Pacific, or a bustling smart‑city hub can all tap into a high‑performance data pipe.

SES expects the new satellites to be fully commissioned by mid‑2027. Once online, they will expand the system’s capacity, improve redundancy and open the door for next‑generation services such as sovereign‑grade secure communications, space‑based data relay and hosted payloads.

Beyond the technical specs, the launch underscores SES’s broader strategy of weaving together multiple orbits – GEO, MEO and LEO – into a seamless, “multi‑orbit” architecture. The idea is simple: let each orbit do what it does best, and let the whole network behave like a single, reliable internet backbone for the planet.

With the constellation now complete, SES joins a small club of operators that can claim a fully‑realized, second‑generation MEO system. The company, headquartered in Luxembourg and listed in Paris and Luxembourg, sees this as a springboard for future innovation, including space‑based AI processing and even more ambitious payloads.

For anyone watching the satellite‑communications space, the take‑away is clear – the era of low‑latency, high‑throughput connectivity from space is no longer a vision; it’s being built, piece by piece, satellite by satellite.
