Late Saturday evening, technicians at Kennedy House Heart in Florida moved the core stage for NASA’s second House Launch System rocket into place between the car’s two solid-fueled boosters.
Working inside the long-lasting 52-story-tall Automobile Meeting Constructing, floor groups used heavy-duty cranes to first elevate the butterscotch-orange core stage from its cradle within the VAB’s cavernous switch aisle, the central passageway between the constructing’s 4 rocket meeting bays. The cranes then rotated the construction vertically, permitting staff to disconnect one of many cranes from the underside of the rocket.
That left the rocket hanging on a 325-ton overhead crane, which might elevate it over the transom into the constructing’s northeast excessive bay. The Boeing-built core stage weighs about 94 tons (85 metric tons), measures about 212 toes (65 meters) tall, and can comprise 730,000 gallons of cryogenic propellant at liftoff. It’s the single largest aspect for NASA’s Artemis II mission, slated to ferry a crew of astronauts across the far aspect of the moon as quickly as subsequent yr.
Lastly, floor crews lowered the rocket between the House Launch System’s twin stable rocket boosters already stacked on a cell launch platform inside Excessive Bay 3, the place NASA assembled House Shuttles and Saturn V rockets for Apollo lunar missions.
On Sunday, groups contained in the VAB related the core stage to every booster at ahead and aft load-bearing connect factors. After finishing electrical and information connections, engineers will stack a cone-shaped adapter on prime of the core stage, adopted by the rocket’s higher stage, one other adapter ring, and at last the Orion spacecraft that might be residence to the four-person Artemis II crew for his or her 10-day journey by deep area.

This would be the first crewed flight of NASA’s Artemis program, which goals to land astronauts on the lunar south pole and finally construct a sustainable human presence on the moon, with a watch towards future expeditions to Mars. This system’s first crewed lunar touchdown is penciled in for the Artemis III mission, once more utilizing SLS and Orion, however including a brand new piece: SpaceX’s monumental Starship rocket might be used as a human-rated lunar lander. Artemis II gained’t land, however it would carry individuals to the neighborhood of the moon for the primary time since 1972.
The core stage for Artemis II arrived from its manufacturing unit in Louisiana final yr, and NASA began stacking the SLS stable rocket boosters in November. Different latest accomplishments on the trail towards Artemis II embrace the set up of the Orion spacecraft’s photo voltaic panels, and closeouts of the craft’s service module at Kennedy House Heart with aerodynamic panels that can jettison throughout launch.
As quickly as subsequent month, the Orion spacecraft will journey to a unique facility at Kennedy for fueling, then to a different constructing to satisfy its Launch Abort System earlier than shifting to the VAB for stacking atop the House Launch System. Forward of the uncrewed Artemis I mission in 2022, it took round eight months to finish these actions earlier than delivering Orion to the VAB, so it’s truthful to be skeptical of NASA’s goal launch date for Artemis II in April 2026, which is already working years not on time.
