Artemis 2 Orion Arrives for Historic Moon Mission Prep
The Orion spacecraft for NASA’s Artemis 2 mission reached the Vehicle Assembly Building (VAB) at Kennedy Space Center on October 16, 2025, marking a pivotal step toward the first crewed lunar voyage since Apollo 17 in 1972. Built by Lockheed Martin with a European Space Agency service module, Orion will be stacked atop the Space Launch System (SLS) rocket for a launch no earlier than February 5, 2026. Acting NASA Administrator Sean Duffy shared images of the arrival, stating, “This step brings Artemis II closer to its historic launch in 2026, paving the way for America’s return to the moon.”
Artemis 2 will carry NASA astronauts Christina Koch, Reid Wiseman, and Victor Glover, alongside Canadian Space Agency astronaut Jeremy Hansen, on a 10-day mission looping around the moon before returning to Earth. The launch window extends through April 2026, with potential dates in February, March, and April. If liftoff occurs on February 5, it will be a nighttime launch.
In August 2025, the final piece of Artemis 2 hardware—the Orion stage adapter—departed NASA’s Marshall Space Flight Center in Huntsville, Alabama, bound for Florida. This lightweight aluminum ring, welded in Marshall’s Materials and Processes Laboratory, connects Orion to the Interim Cryogenic Propulsion Stage. It will also carry cubesats and features a backup rendezvous beacon for orbital maneuvering tests.
Preparations for Artemis 3 are already underway. On August 13, 2025, the integrated core stage engine section and boat-tail for Artemis 3’s SLS were positioned in the VAB’s High Bay 2. NASA expects the RS-25 engines from Stennis Space Center in early 2026, with the core stage arriving from Michoud Assembly Facility in spring.
Despite progress, NASA announced on December 5, 2024, that Artemis 2’s launch would be delayed to April 2026 due to heat shield concerns. During Artemis 1 in 2022, more material ablated from Orion’s heat shield than anticipated. After investigation, NASA concluded the Artemis 2 shield could safely protect the crew with trajectory adjustments.
The Artemis 2 core stage arrived at Kennedy Space Center on July 23, 2024, after a 900-mile voyage aboard NASA’s Pegasus barge from Michoud. The 212-foot stage was moved into the VAB using self-propelled modular transporters for integration with other rocket components.
Crew training and public engagement have been extensive. NASA’s launch team completed its first full practice countdown in 2024. Jeremy Hansen participated in Canada’s Calgary Stampede in 2023, while Canadian Prime Minister Justin Trudeau highlighted the nation’s cold-weather engineering expertise as a factor in its spaceflight contributions, including the Canadarm series.
The Artemis 2 astronauts have spoken openly about the mission’s significance. Commander Reid Wiseman said, “This is a global effort, Artemis 2, and it’s only going to get larger with Artemis 3 and beyond as we get private spaceflight involved. SpaceX is building our lander for Artemis 3.” Pilot Victor Glover emphasized, “We need to celebrate this moment in human history. Because Artemis two is more than a mission to the moon… It is the next step on the journey that gets humanity to Mars.” Mission specialist Christina Koch described the flight profile: “We’re going to hear the words go for launch on top of the most powerful rocket NASA’s ever made… We’re not going to go to the moon right away. We’re gonna stay in an amazing high orbit… and then if everything was good, we’re heading to the moon.” Jeremy Hansen reflected on Canada’s role: “All of those have added up to this moment where a Canadian is going to the moon with our international partnership and it is glorious.”
The Artemis 2 crew was revealed on April 3, 2023, at Ellington Field near Johnson Space Center. Wiseman, a former U.S. Navy fighter pilot, logged 165 days in space in 2014. Glover, also a Navy captain, flew on SpaceX Crew-1 in 2021. Koch holds the record for the longest single spaceflight by a woman at 328 days and completed the first all-female spacewalk. Hansen, a Royal Canadian Air Force colonel, will make his first spaceflight on Artemis 2 after serving as an aquanaut and “cavenaut” in international training programs.
