At approximately 5:30 p.m. EDT (21:00 UTC) today, NASA’s #Artemis I Moon rocket is scheduled to leave launch pad 39B. The Space Launch System rocket and Orion spacecraft will begin its 4-mile (6.4-km) trek atop the crawler-transporter back to the Vehicle Assembly Building (VAB) at NASAKennedy Space Center in Florida. Once inside the VAB, teams will work on replacing a faulty upper stage check valve and a small leak while the supplier for the gaseous nitrogen makes upgrades to their pipeline configuration. Following completion, teams will return to the launch pad to complete the next wet dress rehearsal attempt. Video credit: NASA/Cory S.
