At approximately 5:30 p.m. ET today (April 25, 2022), NASA’s Artemis I Moon rocket is scheduled to leave launchpad 39B atop the crawler-transporter and begin its 4-mile trek to the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida.
Once inside the VAB, teams will work on replacing a faulty upper stage check valve and a small leak within the tail service mast umbilical ground plate housing on the mobile launcher while the supplier for the gaseous nitrogen makes upgrades to their pipeline configuration to support Artemis I testing and launch. Following completion, teams will return to the launch pad to complete the next wet dress rehearsal attempt.

Also in view are the three lightning protection towers and the water tower. The SLS and Orion atop the mobile launcher were transported to the pad on crawler-transporter 2 for a prelaunch test called a wet dress rehearsal. Artemis I will be the first integrated test of the SLS and Orion spacecraft. In future Artemis missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a stepping stone on the way to Mars.
