Since the satellites are Starlink Group 6 satellites, the launch will take place on a southeasterly trajectory.

The launch was originally scheduled for Sunday, but was canceled a few minutes before takeoff. During coverage of the SpaceX launch on Sunday, a launch vehicle operator was heard saying, “Hold. Hold. Hold,” followed by mention of a helium problem in the rocket’s first stage. “Stand back to helium level one,” the operator said. Within seconds, the rocket's vent narrowed. No further details about the helium problem were released.

For the Falcon 9 rocket, the launch cannot be repeated that day once refueling begins. The company launched the CRS-31 space station resupply mission for NASA on Monday evening, waiting at Pad 39A.
