"Gateway's HALO Module Will Journey to US ahead of NASA’s Artemis IV Moon Mission

Gateway’s HALO (Habitation and Logistics Outpost) in a cleanroom at Thales Alenia Space in Turin, Italy. After final installations are complete, it will be packaged and transported to the United States for final outfitting before being integrated with Gateway’s Power and Propulsion Element and launched to lunar orbit.

Image Description: A large cylindrical module, Gateway's Habitation and Logistics Outpost, is suspended by red straps as it is lowered onto a stand in a cleanroom at Thales Alenia Space in Turin, Italy. Engineers and technicians in white lab coats and helmets observe and guide the process. The cleanroom features metal walkways and bright overhead lighting."

"Artemis IV Pressure Vessel and Artemis II European Service Module.

Seen here is the pressure vessel for the Artemis IV mission inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on Feb. 21, 2023. The pressure vessel is the underlying structure of the Orion crew module, containing the pressurized atmosphere astronauts will breathe and work in while in the vacuum of deep space. Artemis IV will be the first operational mission to Gateway – an outpost in lunar orbit serving as a staging point for deep space exploration – followed by a week-long surface mission on the Moon. Using Gateway, NASA will develop a long-term presence on the Moon, using this as a steppingstone before venturing on to Mars."

Orion Crew Modules for Artemis II, Artemis III, and Artemis IV

"The Orion spacecraft for NASA’s crewed Artemis II (right), Artemis III (left), and Artemis IV (center) missions are stationed next to each other inside the high bay of the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on June 22, 2023. Each capsule is in a different stage of production as technicians and engineers prepare the spacecraft to carry astronauts to and around the Moon on their upcoming flights."

"Artemis IV Orion Pressure Vessel Shipped to KSC.

Teams at NASA’s Michoud Assembly Facility in New Orleans prepare the completed Orion pressure vessel for the Artemis IV mission for shipment to NASA’s Kennedy Space Center in Florida. The pressure vessel, which was assembled by lead contractor, Lockheed Martin, is the Orion crew module primary structure – the core upon which all other elements of Orion’s crew module are integrated. The structure is critical to Artemis crews as it holds the pressurized atmosphere astronauts breathe and work in a while in the vacuum of deep space. Once the module arrives at Kennedy’s Vehicle Assembly Building high bay, teams will begin integration of the pressure vessel with the Orion spacecraft crew module adapter and other assembly. With Artemis missions, NASA will land the first woman and the first person of color on the lunar surface, paving the way for human exploration of the Moon and on to Mars."
