8:36 p.m. EDT: SpaceX has confirmed the deployment of the Starlink satellites. The Falcon 9 has landed: 8:27 p.m. EDT: About nine minutes after liftoff the first stage booster of the Falcon 9 has made a landing on the drone ship "Just Read the Instructions" stationed in the Atlantic Ocean off the coast of South Carolina. Deployment of the Starlink stack of satellites should be coming up in about four minutes. Liftoff! SpaceX launches a Falcon 9 Starlink mission on time at 8:18 p.m. EDT from pad 40 at Cape Canaveral Space Force Station in Florida. Inside 5 minutes: 8:13 p.m. EDT: Now inside five minutes to SpaceX's next Falcon 9 launch attempt from Cape Canaveral Space Force Station with 54 Starlink internet satellites. Liftoff is set for 8:18 p.m. EDT. The weather looks favorable for a liftoff attempt this evening. No hardware issues either. Fueling underway: 7:49 p.m. EDT: SpaceX is now flowing propellants – supercooled liquid oxygen and kerosene – into both stages of the 230-foot rocket ahead of an 8:18 p.m. EDT liftoff attempt from pad 40 at Cape Canaveral Space Force Station. SpaceX counting down to 8:18 p.m. liftoff from pad 40: 7:15 p.m. EDT: After five nights of delays SpaceX is counting down once again this evening for a launch attempt at 8:18 p.m EDT from pad 40 at Cape Canaveral Space Force Station. Last night Space Force forecasters with Space Launch Delta 45 predicted a 40% chance of favorable liftoff conditions. "Southwesterly upper-level flow will still bring the potential for anvils from inland convection to move into the area during the count, but lighter winds and drier air will make their persistence less likely than previous days," forecasters said Saturday. "The primary weather concerns for a Sunday evening attempt will be the anvil clouds rules and disturbed weather rule." The SpaceX launch director will give the "go" or "no go" call to proceed with fueling about 38 minutes prior to liftoff. Updates from Friday's real-time event below:
