Story Brief

NASA's Artemis II Space Launch System (SLS) rocket and Orion spacecraft arrived at Launch Pad 39B after an approximately 10-hour journey from the Vehicle Assembly Building (VAB) at the agency's Kennedy Space Center.

Crawler Transporter 2 (CT-2) carried the Moon rocket and its Mobile Launcher-1 (ML-1) back to the historic launch site after a slightly delayed rollout due to high winds. All eyes are now on the final pad flow ahead of a potential NET (No Earlier Than) launch on April 1 in what is the biggest NASA mission in decades.

The rollout was planned for the evening of March 19 but shifted due to conditions; the planned 8 p.m. local first motion time was delayed by high winds.
