CAPE CANAVERAL, Fla. — After several delays, SpaceX finally launched its Starlink 10-7 mission Monday morning. 

The Falcon 9 rocket lifted off from the Kennedy Space Center at 6:37 a.m.

The mission was originally scheduled for Aug. 10 at 9:03 a.m., following the successful launch of the Starlink 8-3 mission Saturday morning. 

The 10-7 mission was moved to Sunday morning at 7:21 a.m., then delayed again at 10:49 a.m., and a third time at 10:59 a.m. 

Just as the company’s Falcon 9 rocket was about to take off, SpaceX had reset its launch to Monday morning.

The countdown was held at 46 seconds before takeoff Sunday morning.

SpaceX's Starlink 8-3 mission sent up 21 Starlink satellites aboard their Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station after its first attempt was pushed back.

On Friday, SpaceX pushed its Starlink 8-3 mission to Saturday morning after the company cited weather conditions at the recovery site for the postponement.
