Saturday night, Technicians at Kennedy Space Center, Florida moved to the core stage NASA’s The second space launch system rocket enters position between the vehicle’s two solid fuel boosters.
The ground team worked within the iconic 52-story high vehicle assembly, using heavy cranes to lift the Cream Orange core stage from its cradle in the sponge-like transfer aisle of VAB, a central passage between the building’s four rocket assembly brackets. The crane then rotates vertically so that workers can disconnect one of the cranes from the bottom of the rocket.
That hangs the rocket on a 325-ton top crane, which lifts it up to the beams of the high bay northeast of the building. The core phase of the Boeing construction weighs about 94 tons (85 metric tons) and is about 212 feet (65 meters) high, and will contain 730,000 gallons of cryogenic propellant when lifting. It is the largest element of NASA Artemis II Missionplan to transport a group of astronauts along the far end of the fleet moon next year.
Ultimately, the ground crew lowered the rockets between the space launch system’s dual solid rocket boosters that had been stacked on a mobile launch platform within High Bay 3, where NASA assembled the space shuttle and Asaturn V rockets for Apollo lunar missions.
On Sunday, the team inside VAB connected the core stage to each booster at the forward and stern bearing points. After completing the electrical and data connections, the engineers will stack a cone adapter on the top of the core stage, then the Rocket’s upper stage, another adapter ring, and finally the Orion spacecraft, which will be the location of the four-person Artemis II crew so that they can travel through deep space on a 10-day journey.

By action
This will be the first crew flight of NASA’s Artemis program, which aims to land astronauts on the Lunar South Pole and ultimately establish a sustainable human presence on the moon, with a focus on future expeditions to Mars. The first crew of the program, Lunar Landing, was engraved in the Artemis III mission, using SLS and Orion again, but added new works: SpaceX’s The giant starship rocket will be used as a human-level lunar lander. The Artemis II will not land, but it will bring people near the moon for the first time since 1972.
Last year, the core phase of Artemis II came from a Louisiana factory, and NASA began stacking SLS Solid Rocket boosters in November. Other latest achievements on the road to Artemis II include solar panels installed with the Orion spacecraft, as well as the closure of the process service module at the Kennedy Space Center and equipped with aerodynamic panels that will be placed during launch.
Next month, the Orion spacecraft will head to another Kennedy factory to refuel, then head to another building to meet its launch abortion system, and then move to VAB to stack it on the space launch system. It took about eight months to complete these activities before the delivery of Orion to VAB before the 2022 unforeseen Artemis I mission, so it is fair to doubt that NASA is targeted launch date for Artemis II in April 2026, which has lagged behind plans.
