Teams with NASA’s Exploration Ground Systems Program lift the agency’s SLS (Space Launch System) core stage for the Artemis II mission from horizonal to vertical inside the transfer aisle at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Tuesday, Dec. 10, 2024. The one-of-a kind lifting beam is designed to move the core stage from the transfer aisle to High Bay 2 where it will remain while teams stack the two solid rocket boosters for the SLS core stage.

A heavy-lift crane has been attached to the Core Stage Inter-tank Umbilical (CSITU) to lift it up from a flatbed truck near the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. The CSITU will be lifted up to about the 140-foot level of the mobile launcher (ML) tower for a fit check of the attachment hardware. It will be lowered down and installed permanently on the ML at a later date. The CSITU is a swing-arm umbilical that will connect to the Space Launch System core stage inter-tank. It will provide conditioned air, pressurized gases and power and data connection to the core stage. The Ground Systems Development and Operations Program is overseeing installation of the umbilicals.

The Space Launch System (SLS) core stage is seen atop the mobile launcher inside High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on June 12, 2021. Teams with NASA’s Exploration Ground Systems and contractor Jacobs lifted and lowered the core stage – the largest part of the rocket – onto the mobile launcher, placing it in between the twin solid rocket boosters. The 188,000-pound core stage, with its four RS-25 engines, will provide more than 2 million pounds of thrust during launch and ascent, and coupled with the boosters, will provide more than 8.8 million pounds of thrust to send the Artemis I mission to space. Under the Artemis program, NASA will land the first woman and first person of color on the Moon, as well as establish a sustainable presence on the lunar surface in preparation for human missions to Mars.

Teams with NASA’s Exploration Ground Systems and primary contractor Amentum, use a massive crane to lift to vertical the SLS (Space Launch System) Moon rocket for Artemis II on Saturday, March 22, 2025, inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. The move from the facility’s transfer aisle into High Bay 3 allows technicians to integrate the 212-foot-tall core stage with the stacked solid rocket boosters onto mobile launcher 1. Artemis II is the first crewed test flight under NASA’s Artemis campaign and is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.

The 212-foot core stage will undergo final checkouts before being lifted into the VAB’s High Bay 3 for integration alongside the completed stack of twin solid rocket booster segments.

Teams with NASA’s Exploration Ground Systems and contractor Jacobs lift the Space Launch System (SLS) core stage – the largest part of the rocket – and prepare to move it over to High Bay 3 in the Vehicle Assembly Building, where it will be placed atop the mobile launcher in between the twin solid rocket boosters, at NASA’s Kennedy Space Center in Florida on June 12, 2021. The 188,000-pound core stage, with its four RS-25 engines, will provide more than 2 million pounds of thrust during launch and ascent, and coupled with the boosters, will provide more than 8.8 million pounds of thrust to send the Artemis I mission to space. Under the Artemis program, NASA will land the first woman and first person of color on the Moon, as well as establish a sustainable presence on the lunar surface in preparation for human missions to Mars.

The Pegasus Barge made its first delivery to Kennedy in support of the agency's Artemis missions. The pathfinder is being used by Exploration Ground Systems and its contractor, Jacobs, to practice offloading, moving and stacking maneuvers, using important ground support equipment to train employees and certify all the equipment works properly. The pathfinder will stay at Kennedy through at least the month of October before trekking back to NASA's Michoud Assembly Facility in Louisiana.
