Technicians with Exploration Ground Systems prepare to transfer and lift the right forward segment for NASA’s SLS (Space Launch System) Moon rocket boosters into High Bay 3 inside NASA’s Vehicle Assembly Building in Florida on Wednesday, Feb. 12, 2025. The right forward segment will be attached to the center forward segment on mobile launcher 1. The twin solid boosters, five segments on each side, will help support the remaining rocket components and the Orion spacecraft during final assembly of the Artemis II Moon rocket and provide more than 75 percent of the total SLS thrust during liftoff from NASA Kennedy’s Launch Pad 39B.

Technicians with NASA’s Exploration Ground Systems use a crane in the transfer aisle of the Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida to prepare to lift the left forward segment for NASA’s SLS (Space Launch System) Moon rocket boosters on Wednesday, Feb. 5, 2025.

Teams at Kennedy Space Center in Florida transported the fourth core stage engine section from the spaceport’s Space Systems Processing Facility to the Vehicle Assembly Building in August 2025. The flight hardware will remain in the facility’s transfer aisle until teams lift the section into High Bay 2 for assembly and integration with the remaining core stage elements. Artemis will pave the way for a long-term human presence on the lunar surface while ushering the Golden Age of Innovation and Exploration.
