Story Brief

After a 900-mile (1,448-kilometer) barge trip from NASA's Michoud Assembly Facility in New Orleans, the top four-fifths (TFF) of Core Stage 3 (CS3) arrived at NASA's Kennedy Space Center in Florida.

Why it matters: Moving final assembly and engine integration to Kennedy Space Center brings the work directly to the launch site, advancing Artemis III preparations while supporting NASA's accelerated mission schedule and Boeing's efficiency efforts to speed core stage deliveries.

Teams will now prepare the hardware for vertical integration with the engine section.
