UPDATE: NASA had planned to start the rollout on Thursday but is now aiming to begin the process two days earlier, on Tuesday evening ET. This article has been updated to reflect this change.
NASA is gearing up for its biggest launch of the year: The Artemis I mission, which will send an uncrewed spacecraft into orbit around the moon and return it back to Earth ahead of future missions to bring astronauts back to the moon. Before any astronauts blast off, however, NASA needs to test its new rocket (the Space Launch System) and new capsule (Orion) to ensure that they are safe and ready to carry people.
Artemis I will launch from Launch Complex 39B (LC-39B) at the Kennedy Space Center and make a flyby of the moon, collecting scientific data as well as testing out the new technology. The launch window for the mission is set to open on August 29, and the agency will be livestreaming the whole launch event. But the preparations for the launch are already beginning this week, with the enormous 320-foot-tall Space Launch System rocket being rolled out to the launch pad on the evening of Tuesday, August 16.
To watch the stately progress of the rocket as it is carried by a special crawler on the four-mile journey to the launch pad, fire up the video player at the top of this page or head to NASA’s Kennedy Space Center’s YouTube channel, where a livestream will show the progress of the rocket beginning at 9 p.m. ET (6 p.m. PT) on Tuesday, August 16.
NASA is also working on final preparations for the launch, with the rocket currently located in the Vehicle Assembly Building at Kennedy. This includes testing the system which can terminate the launch in the case of an emergency, called the flight termination system test. Once this is complete, the access platforms which allow crew access to the rocket will be retracted and the rollout can begin.
