SpaceX is targeting Sunday, September 13 for a Falcon 9 launch of the SES O3b mPOWER mission to medium Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The 87-minute launch window opens at 2:49 p.m. ET. If needed, a backup opportunity is available Monday, September 14 with the same window. 

A live webcast of this mission will begin about 15 minutes prior to liftoff, which you can watch here and on X @SpaceX. 

This will be the 29th flight for the first stage booster supporting this mission, which previously supported Ax-2, Euclid, Ax-3, CRS-30, SES ASTRA 1P, NG-21, and 22 Starlink missions. Following stage separation, the first stage will land on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean.
