Live coverage: SpaceX to launch final 3 O3b mPOWER satellites for SES – Spaceflight Now
SpaceX plans to launch the final three O3b mPOWER satellites for SES on a Falcon 9 rocket from Florida on Sunday. The launch window opens at 2:49 p.m. EDT, with a 60% chance of favorable weather. The satellites, built by Boeing, will complete the O3b mPOWER constellation in medium Earth orbit. SES expects the satellites to enter service by mid-2027, enhancing the constellation's capabilities to meet growing demand.
How this was made

The 30-second read
Why it matters
The successful deployment will enable SES to offer expanded broadband services, though short‑term stock movement may be muted pending performance verification.
Market read
SES's completion of the O3b constellation could modestly boost its stock, while reinforcing the broader satellite communications sector.
What to watch
Contract terms, revenue recognition timing, and competition from other constellations may limit the expected impact on SES.
Background
SpaceX is set to launch the final three O3b mPOWER satellites for SES from Cape Canaveral on Sunday, completing the 13‑satellite MEO constellation.
Ticker impact
SES will receive its final three O3b mPOWER satellites as SpaceX launches them, completing the constellation.
Modest upside for SES if the satellites perform as expected; limited downside unless launch delays occur.
Completion of the constellation is a positive development, but the market impact depends on operational success and timing of service rollout.
Market effects
The satellite communications sector gains visibility as the O3b mPOWER constellation becomes fully operational, potentially boosting demand for MEO services.
SES's enhanced capacity may improve broadband offerings in Europe and Africa, influencing regional telecom operators.
Completion of the O3b network strengthens global broadband connectivity, affecting satellite industry dynamics worldwide.
Counterpoint
Potential launch delays or satellite performance issues could dampen SES's upside and weigh on its stock.
