10:25am CT Update: Monday morning's launch attempt of the Starlink-12 mission was scrubbed in the last moments of the countdown due to thick clouds over the launch site at Kennedy Space Center. SpaceX does not have a back-up launch window for this mission because there are two launches scheduled over the next two days.

Having fixed an issue with its retraction arm at Launch Complex-37, United Launch Alliance has an opportunity to launch the NROL-44 mission on its Delta IV Heavy rocket at 12:02am ET on Tuesday (04:02 UTC). And SpaceX has the launch of a GPS III satellite planned from its other Florida launch pad on Tuesday night, at 9:55pm ET (01:55 UTC Wednesday).

Original post: SpaceX returns to its launch pad at Kennedy Space Center on Monday for its twelfth launch of operational Starlink satellites. The mission is scheduled to lift off from Launch Complex-39A at 10:22am ET (14:22 UTC). Weather conditions are 70-percent favorable for liftoff.
