Boeing has delivered the second core stage of the Space Launch System (SLS) rocket to NASA. Constructed at NASA’s Michoud Assembly Facility (MAF), this core stage is pivotal for sending the Artemis II crew to lunar orbit, marking the first crewed lunar mission in 50 years.
This largest component of the Artemis II mission, built by Boeing, will be transported 900 miles to NASA’s Kennedy Space Center aboard the Pegasus barge. Upon arrival, it will be integrated with the other Artemis II components, including the upper stage, solid rocket boosters, and NASA’s Orion spacecraft inside the Vehicle Assembly Building. This integration is a critical milestone in preparing for the Artemis II launch, slated for 2025.
The delivery of Core Stage 2 represents a significant milestone in the SLS rocket’s development. Standing over 200 feet tall and powered by four RS-25 engines, along with two solid-fueled booster rockets, this core stage will generate the 8.8 million pounds of thrust needed to launch Artemis II and future missions into space.
The SLS is the only rocket capable of carrying crew and large cargo to the moon and beyond in a single launch. Its exceptional capabilities will support human-rated spacecraft, habitats, and scientific missions to the moon, Mars, and beyond.
