After completing its journey from NASA’s Stennis Space Center in Mississippi aboard the Pegasus barge, teams with Exploration Ground Systems (EGS) and lead contractor Jacobs transport the massive Space Launch System (SLS) core stage to Kennedy Space Center’s Vehicle Assembly Building in Florida on April 29, 2021 in this aerial view. A NASA helicopter is in view in the upper left of the photograph. Once inside the VAB, the core stage will be prepared for integration with the completed stack of solid rocket boosters atop the mobile launcher ahead of the Artemis I launch. The first in a series of increasingly complex missions, Artemis I will test SLS and Orion as an integrated system prior to crewed flights to the Moon.
