At NASA’s Michoud Assembly Facility in New Orleans, technicians from Orion prime contractor Lockheed Martin have welded together three cone-shaped panels on Orion’s crew module for the Artemis III mission that will land the first woman and next man on the moon.

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.

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.

NASA selects possible landing regions for next astronauts on moon

NASA has identified 13 regions located near the lunar south pole where astronauts may next land on the moon, possibly as soon as 2025.

The space agency on Friday (Aug. 19) revealed the general areas that a team of scientists and engineers determined could meet the requirements for the planned Artemis III mission, including seeking out water ice in the permanently shadowed craters of the lunar south pole. Each of the regions contain multiple potential sites where SpaceX's Starship human landing system (HLS) — NASA's chosen lunar lander for the Artemis III mission — could safely touch down with the first humans to explore the lunar surface since the last Apollo mission more than 50 years ago.

NASA release
NASA advances moon rocket production for Artemis III, future missions

NASA is moving forward with Space Launch System (SLS) production and assembly activities for future Artemis missions.

The barge will ferry the engine section of NASA’s Space Launch System (SLS) rocket for Artemis III to the agency’s Kennedy Space Center in Florida. Teams at Kennedy will finish outfitting the engine section, which comprises the tail-end of the 212-foot-tall core stage, before integrating it with the rest of the stage. (NASA/Michael DeMocker)

The agency is optimizing manufacturing capabilities by enabling SLS core stage lead contractor Boeing to use facilities at NASA's Kennedy Space Center in Florida to perform some core stage assembly and outfitting activities beginning with the Artemis III rocket. In tandem, teams will continue all core stage manufacturing activities at NASA's Michoud Assembly Facility in New Orleans.

As the SLS program transitions from rocket development efforts to operations, NASA and Boeing evaluated how to improve upon the time required to produce each core stage and best use space at Michoud.

"We're making progress developing, manufacturing, and assembling elements for future Artemis missions," said Jim Free, associate administrator for the Exploration Systems Development Mission Directorate. "Our collective workforce across NASA centers and industry partners plays a key role in accomplishing NASA's long-term plans for exploring the Moon."

Beginning with production for Artemis III, NASA and Boeing will use Michoud, where the SLS core stages are currently manufactured, to produce and outfit the core stage elements, and available space at Kennedy for final assembly and integration. This opportunity provides for multiple mission elements to be manufactured and outfitted at the same time and for the workforce at Michoud to begin building the rocket's exploration upper stage, which will enable SLS to send even heavier and larger cargo to the Moon on the same missions with astronauts beginning with Artemis IV.

All five major core stage structures will be manufactured at Michoud using current robotic welding tools and fixtures and complete all thermal protection system spray applications at Michoud. There, the forward skirt, the intertank, liquid oxygen tank, and the liquid hydrogen will continue to be outfitted and joined to form the upper part of the core stage. Upon completion, these structures, which comprise the top four-fifths of the 212-foot-tall stage, will be shipped to Kennedy's Vehicle Assembly Building (VAB) where they will be joined and vertically integrated in High Bay 2.

Once the engine section structure is manufactured, it will be transported to Kennedy's Space Station Processing Facility for outfitting in the facility. When the engine section is completely outfitted, it and the stage's four RS-25 engines will be moved to the VAB's High Bay 2 for integration with the rest of the core stage, where technicians can more easily move it for stacking and assembly operations.

Four of five major core stage parts for Artemis II have been joined, and teams are outfitting the last part, the engine section, and will soon connect it and the RS-25 engines to complete the stage at Michoud. The Artemis II stage is scheduled to be completed and delivered to Kennedy in 2023. The engine section for the Artemis III SLS core stage is expected to arrive at Kennedy in mid-December.
