"Pad 40 has been the primary Falcon 9 launch site for most of the rocket's history, while Pad 39A provided a location for crew launches and an augmentation to support SpaceX's growing launch cadence. But there are signs the Falcon 9 launch cadence, which reached 165 missions last year, may be peaking as the company turns its attention to Starship. And SpaceX has steadily reduced the time it takes to reconfigure Pad 40 between launches, cutting the turnaround time to less than 48 hours."
""To physically get access to those, the arm needs to be removed," Gerstenmaier said. "Those bearings have to come out and they have to be reinstalled. We'll do that work at the Kennedy Space Center. And the intent there is, we don't need to put the arm back up ... When we get a call-up for a mission and we have to go fly a mission, if it requires that, we have plenty of time to get the arm back up.""
"SpaceX has continued launching Falcon 9 and Falcon Heavy rockets from Pad 39A amid the nearby construction work to prepare for Starship flights. "That doesn't impact our ability to launch from the pad," Gerstenmaier said. That could change as SpaceX begins testing and launching Starships from Kennedy Space Center. Starship launch operations may routinely force the closure of Pad 39A to personnel."
Pad 40 served as the primary Falcon 9 launch site for most of the rocket's history, while Pad 39A hosted crew launches and supplemented launch capacity. Falcon 9 launch cadence reached 165 missions last year and may be peaking as resources shift toward Starship development. SpaceX reduced Pad 40 reconfiguration turnaround to less than 48 hours. The crew access arm at Pad 39A was removed to access and repair bearings that connect the arm to the pad tower. Bearings will be repaired and reinstalled at Kennedy Space Center, with the arm kept down unless a crew mission requires reinstallation. Starship testing and launches could at times close Pad 39A to personnel.
