NASA’s Artemis 1 flight vehicle is headed back to the Vehicle Assembly Building (VAB) at the Kennedy Space Center (KSC) after a month at Launch Pad 39B attempting to complete the final test before its first launch.
The Wet Dress Rehearsal (WDR), a countdown demonstration test with the integrated Orion spacecraft and Space Launch System (SLS) rocket for Artemis 1 loaded with propellant, was attempted three times in April, but a hydrogen leak on the Mobile Launcher and unreliable gaseous nitrogen (GN2) service finally pulled the plug on staying at the launch pad.
