Space Launch System (SLS)
rocket for NASA’s Artemis 1 lunar test flight is returning to Launch Pad 39B at the Kennedy Space Center
Repairs and maintenance
were performed in May, both in the Vehicle Assembly Building & at the Air Liquide nitrogen plant.
Attempts to complete
the Wet Dress Rehearsal (WDR) countdown demonstration test were delayed by multiple outages of gaseous nitrogen
SLS vehicle is going back
to the pad six weeks after leaving to address issues uncovered during the 3 Wet Dress Rehearsal attempts in April
Problems were found with
flight and ground systems at the pad and with gaseous nitrogen (GN2) supply systems at Air Liquide’s plant.
launch teams will take
about two weeks to prepare Orion, SLS, the Mobile Launcher, and the pad for the “launch day” of the next Wet Dress Rehearsal attempt
