Current Artemis Launch Date and Official NASA Timeline
The Artemis program, led by NASA with Boeing and Lockheed Martin, has targeted multiple launch windows for its uncrewed and crewed moon missions, with the exact Artemis launch date shifting based on vehicle readiness, range availability, and technical reviews. Official updates are published through NASA's Artemis page and press releases, which track the planned launch date for each mission in the campaign. The next major milestone is the integrated wet dress rehearsal and launch readiness review for the Space Launch System rocket and Orion spacecraft at Kennedy Space Center, which determine the final go for the next launch attempt. As of the latest public data, the agency has continued to adjust the target launch date to align with hardware testing, flight software validation, and range scheduling at the Cape Canaveral Space Force Station. For detailed mission planning and current target dates, see the official NASA Artemis page at https://www.nasa.gov/artemis and the Kennedy Space Center mission updates at https://www.kennedy.spacecenter.nasa.gov/missions/artemis.
NASA's launch date decisions follow a structured flight readiness process that includes flight readiness reviews, launch commit criteria checks, and coordination with the U.S. Space Force Eastern Range. The agency publishes target launch dates in its integrated master schedule and updates them after each test campaign, anomaly resolution, and launch commit criteria review. These dates are tied to specific mission designations, such as Artemis I, II, and III, and are influenced by factors like booster stacking completion, mobile launcher integration, and countdown demonstration tests. The latest public statements from NASA and its contractors indicate that the next launch attempt will occur once remaining closeout work, flight software verification, and range safety checks are successfully completed.
Artemis Mission Architecture, Vehicles, and Launch Infrastructure
Space Launch System Rocket and Orion Spacecraft Configuration
The Artemis missions rely on the Space Launch System rocket, built primarily by Boeing, and the Orion crew capsule built by Lockheed Martin, with launch operations managed out of Kennedy Space Center's Vehicle Assembly Building and Launch Pad 39B. Each flight uses a specific SLS configuration, from the Block 1 vehicle for early missions to future Block 1B and Block 2 designs intended for deeper exploration, and the launch date for each configuration is set after integration and testing milestones are met. The rocket's core stage, solid rocket boosters, and upper stage are integrated vertically in the VAB, followed by rollout to the pad, where the mobile launcher and launch tower support the countdown and lift-off sequence. For technical details on the SLS and Orion, see the NASA SLS page at https://www.nasa.gov/sls and the Lockheed Martin Orion overview at https://www.lockheedmartin.com/en-us/products/deep-space-exploration/orion.html.
Ground systems at Kennedy Space Center, including the crawler-transporter, launch tower, and mobile launcher, are critical to the launch date because they must support the SLS stack's size and weight while meeting safety and operational requirements. The launch date is also tied to the readiness of the Exploration Ground Systems team, which handles tanking operations, terminal count sequences, and emergency escape procedures during the launch window. Weather constraints, range availability, and contingency planning for technical holds further shape the final launch date, with the agency aiming to maximize the probability of a successful countdown and ascent profile. These infrastructure factors are reviewed during the flight readiness review and launch commit criteria meetings, which involve NASA, the U.S. Space Force, and contractor teams.
