If needed, SpaceX officials said they could reinstall the crew arm for Dragon missions launching from Pad 39A.
Repairs required
Bill Gerstenmaier, SpaceX’s vice president of build and flight reliability, said there’s another pressing reason for removing the crew arm at Pad 39A. The bearings that connect the arm to the launch pad’s tower need repairs.
“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.
“The right thing to do is get those bearings replaced in the environment on the ground, make some upgrades to them, and then we’ll be ready to go and put the arm back up when it’s time to go fly, if we need to go fly,” Gerstenmaier said.
