# Inside KSC! for Sept. 18, 2020 7r-6M2HVkgE

Teams with NASA's Exploration Ground Systems rehearsed booster stacking operations using mock-ups, referred to as pathfinders, inside the Vehicle Assembly Building at the agency's Kennedy Space Center in Florida. The exercise involved preparing an aft pathfinder segment in High Bay 4, lifting and moving it over to High Bay 3, and placing it on the mobile launcher. A center pathfinder segment also was added to the stack. Also this week, Kennedy employees participated in the Occupational Safety and Health Administration's \"stand down to prevent falls\" campaign.
