The Falcon 9 lifted off from Florida's Cape Canaveral Space Force Station today at 5:12 p.m. EDT (2112 GMT), carrying SES' O3b mPOWER 9 and 10 satellites toward medium Earth orbit (MEO), about 5,000 miles (8,000 kilometers) above our planet.

SpaceX Falcon 9 rocket will launch from Vandenberg in California on a NASA mission. Where are some spots to watch liftoff? Will there be a sonic boom?

SpaceX, which has long deployed its Starlink satellites from Florida, is increasingly launching the missions from California. There's a good reason.
