English: Technicians from Orion Prime Contractor Lockheed Martin weld the forward bulkhead of the pressure vessel to the tunnel hardware on the Orion Spacecraft for the Artemis III mission at NASA’s Michoud Assembly Facility in New Orleans. The crew module’s primary structure, the pressure vessel, is comprised of seven machined aluminum alloy pieces that are welded together through a weld process that produces a strong, air-tight habitable space for astronauts during the mission. The pressure vessel is designed to withstand the harsh and demanding environment of deep space and is the core structure upon which all the other elements of Orion’s crew module are integrated. This pressure vessel weld is the next step following the completion of the crew module cone panel welds and creates the top of the spacecraft. Work will then begin to join the barrel with the aft bulkhead to form the bottom of Orion. Last, the forward bulkhead will be welded to the top of the panels and, for the seventh and closeout weld, the bottom of the cone panels will be joined to the barrel to complete the pressure vessel. Once welding of the Artemis III crew module primary structure is complete, it will be shipped to NASA’s Kennedy Space Center in Florida where it will undergo further assembly beginning this fall. Orion, the Space Launch System, and Exploration Ground Systems programs are foundational elements of the Artemis program. Artemis I will be the first integrated flight test of Orion and SLS and is targeted to launch later this year. Artemis II will follow and is the first crewed mission, taking humans farther into space than ever before.
