NASA’s Space Launch System and Orion spacecraft atop the mobile launcher are in view in High Bay 3 of the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida on Tuesday, Aug. 16, 2022. All of the work platforms have been retracted in preparation for rollout to Launch Complex 39B ahead of launch of Artemis I. The crawler-transporter, driven by engineers, is under the Artemis I stack atop the mobile launcher and will carry it 4.2 miles via the crawlerway that connects the VAB to the launch pad. The agency’s Artemis I flight test is scheduled to liftoff on Monday, Aug. 29. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by launching Orion atop the SLS rocket, operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown.
