Orion Spacecraft Completes Major Stacking Milestone Ahead of Artemis II Mission
Lockheed Martin (NYSE: LMT) reported that the Orion spacecraft named Integrity was stacked atop the Space Launch System (SLS) rocket in High Bay 3 at Kennedy Space Center on Oct. 19, 2025, marking a major prelaunch milestone for Artemis II. Teams will complete electrical, data and umbilical hookups and EGS will run integrated tests before the stack rolls to Launch Pad 39B for a wet dress rehearsal next year. The first crewed Artemis flight is scheduled no earlier than February 2026, with launch windows extending through April 2026, and a planned mission duration of 10 days. Lockheed Martin is the prime contractor and built Orion's crew module, adapter and launch abort system.

Insights
Orion and SLS stacking completes a key hardware integration milestone ahead of the crewed Artemis II launch window.
The physical mating of the Orion spacecraft named Integrity to the SLS rocket on
Dependencies and risks remain concrete and procedural: completion of the described electrical/data connections, successful integrated tests, and a successful wet dress rehearsal are all required prior to launch. Watch the outcomes and timings of the integrated test campaign and the wet dress rehearsal over the next few months; those discrete milestones will directly determine whether the program meets the early
Orion Integrity spacecraft connected with the SLS rocket, readying for historic crewed journey to the Moon
The Orion spacecraft, named Integrity by its astronaut crew, was transported to the Vehicle Assembly Building at the
"Integration of SLS and Orion represents a major milestone in our progress on Artemis," said Acting NASA Administrator Sean Duffy. "Soon, we will be launching four astronauts around the Moon for the first time in over half a century on Artemis II — the latest demonstration of American dominance in space."
Following the mating, teams will make electrical and data connections between Orion and SLS, along with umbilical connections from the mobile launch platform to the spacecraft. EGS will conduct integrated tests of Orion and SLS before they are rolled out to Launch Pad 39B for a wet dress rehearsal next year.
"The full stack of Orion on the SLS is a truly spectacular sight," said Robert Lightfoot, president of Lockheed Martin Space. "Our teams have been working tirelessly to finalize these last steps and ensure Orion takes the crew to the Moon and brings them home safely."
The first crewed flight of the Artemis program is set to launch no earlier than February 2026, with potential launch windows extending through April 2026. The mission will be 10 days and is a key event to establishing a long-term presence at the Moon for exploration and science.
Orion is the most advanced, human-rated, deep space spacecraft ever developed. Lockheed Martin is the prime contractor to NASA for Orion and built the crew module, crew module adaptor and launch abort system.
