NASA barge delivers first SLS core stage to Kennedy Space Center

The core stage of NASA’s first Space Launch System heavy-lift rocket arrived at the Kennedy Space Center on Tuesday evening aboard a specially-built barge, completing a voyage by sea from a test site in Mississippi to begin final preparations for the first flight of NASA’s Artemis Moon program. Ground crews plan to transport the core stage into the Vehicle Assembly Building beginning around 5:30 a.m. EDT (0930 GMT) Thursday to join its two solid rocket boosters.

Hydraulic system issue triggered early engine shutdown during SLS test-firing

NASA officials said Tuesday the weekend test-firing of the Space Launch System moon rocket’s core stage was cut short by an out-of-limits parameter in a hydraulic system for gimbaling, or vectoring, one of its engines. NASA Administrator Jim Bridenstine told Spaceflight Now engineers are “feeling pretty good” about the data gathered during the shortened test-firing, and managers may decide to ship the SLS core stage to the Kennedy Space Center for launch preparations without re-attempting the planned eight-minute hot fire.
