A Kennedy Space Center employee walks near NASA’s crawler-transporter 2 at Kennedy’s Launch Complex 39B area in Florida on June 28, 2019. The crawler-transporter 2 successfully carried Exploration Ground Systems’ mobile launcher to the pad from the Vehicle Assembly Building, departing at midnight on June 27. On June 28, the mobile launcher continued its journey up to the pad surface, where it will remain for the summer, undergoing final testing and checkouts. Its next roll to the pad will be with the agency’s Space Launch System rocket and Orion in preparation for the launch of Artemis 1.
