Artemis IV is a planned crewed lunar mission within the Artemis program led by the National Aeronautics and Space Administration. The mission builds on prior expeditions including Artemis I, Artemis II, and Artemis III and integrates contributions from international partners such as the European Space Agency and the Japan Aerospace Exploration Agency. Artemis IV aims to expand human presence near the Moon through rendezvous with cislunar infrastructure like the Lunar Gateway and deployment of scientific and logistical payloads.
Development of Artemis IV stems from strategic directives articulated by the United States Congress and policy guidance from the White House. Programmatic milestones were influenced by earlier programs including Apollo program, Constellation program, and the commercial crew initiatives involving SpaceX and Sierra Nevada Corporation. Industrial partners include Boeing, Lockheed Martin, Northrop Grumman, Blue Origin, and Maxar Technologies. International frameworks such as the Artemis Accords and bilateral agreements with the Canadian Space Agency shaped hardware contributions and crew roles. Funding cycles through the United States Senate and program assessments by the Government Accountability Office affected timelines. Testing and certification drew on facilities at Michoud Assembly Facility, Stennis Space Center, and Kennedy Space Center.
Primary crew transportation is the Orion capsule launched on the Space Launch System core stage and boosters produced by Aerojet Rocketdyne. Rendezvous and gateway operations rely on components from the Lunar Gateway project, including habitation modules built by the European Space Agency and logistics vehicles by Northrop Grumman's Cygnus heritage. Secondary payloads include rovers from Hankook, scientific instruments from Jet Propulsion Laboratory, and sample caching systems developed by NASA Goddard Space Flight Center and JAXA. Cargo manifests incorporate experiments from the Canadian Space Agency's robotic arm technology, materials science packages from European Space Agency laboratories, and life sciences studies from Roscosmos-affiliated investigators under interagency agreements. Communications architecture uses networks operated by Deep Space Network facilities managed by Jet Propulsion Laboratory and commercial services contracted with Intelsat.
Mission objectives emphasize crewed lunar orbital operations, cargo delivery to Lunar Gateway, technology demonstrations, and preparatory activities for sustained surface exploration outlined by the National Space Council. Profile phases include Earth departure from Kennedy Space Center, translunar injection aided by the Space Launch System second-stage, lunar orbit insertion for Near-Rectilinear Halo Orbit rendezvous, docking with the Lunar Gateway's power and propulsion module, and return to Earth with splashdown in recovery zones coordinated by the United States Department of Defense. The mission supports broader architecture goals articulated by Space Policy Directive 1 and programmatic objectives endorsed by the National Research Council.
Crew selection involved personnel drawn from NASA Astronaut Group 22 and earlier cohorts with adjunct selection by partners including European Astronaut Corps and JAXA Astronaut Corps. Training regimes incorporated simulations at Johnson Space Center's Neutral Buoyancy Laboratory, extravehicular activity rehearsals with suited systems developed by Axiom Space and Collins Aerospace, and habitat operations practiced in analog sites such as Biosphere 2 and the International Space Station modules. Medical and behavioral preparation engaged clinicians from National Institutes of Health and flight surgeons coordinated under NASA Flight Operations Directorate. Mission-specific geology training occurred with experts from the United States Geological Survey and planetology groups at Smithsonian Institution affiliates.
Launch operations are staged from Kennedy Space Center Launch Complex 39B with integration at Vehicle Assembly Building using cranes and mobile launcher platforms. The Space Launch System core employs eight RS-25 engines with solid rocket boosters derived from Whiteshell Research Establishment heritage suppliers; upper-stage operations utilize an interim cryogenic propulsion stage. Trajectory planning involved teams at Ames Research Center and Jet Propulsion Laboratory optimizing translunar injection windows, mid-course correction maneuvers, and lunar orbit insertion burns to reach a Near-Rectilinear Halo Orbit for Gateway docking. Recovery coordination with United States Navy and United States Marine Corps assets ensures crew retrieval after Earth reentry and splashdown.
Scientific objectives include astrophysics observations leveraging instruments from the European Southern Observatory and Smithsonian Astrophysical Observatory, lunar geology studies supported by samples prepared for curation at Smithsonian Institution facilities, and regolith interaction experiments developed by NASA Glenn Research Center. Technology demonstrations involve in-situ resource utilization prototypes from NASA Marshall Space Flight Center and additive manufacturing units provided by Made In Space (company). Biology investigations include radiation exposure studies with protocols from National Cancer Institute collaborators, and human factors research coordinated with Massachusetts Institute of Technology and Stanford University. Outreach and education initiatives are planned in cooperation with the Smithsonian Institution and Exploratorium.
Risk mitigation strategies include redundant life support systems engineered by Lockheed Martin and Hamilton Sundstrand, abort modes validated through simulations at Johnson Space Center, and launch commit criteria enforced by NASA Launch Services Program. Contingency plans cover on-orbit anomalies with support from the United States Space Force's space surveillance assets and international rescue coordination channels involving the European Space Agency and Canadian Space Agency. Medical evacuation and rehabilitation pathways link to Walter Reed National Military Medical Center and international medical response teams. Safety protocols conform to standards set by the National Transportation Safety Board and oversight by the Office of Inspector General.
