Artemis I Launch Date and Current Mission Status
The Artemis I mission is an uncrewed flight test of NASA's Space Launch System rocket and Orion spacecraft, currently targeting a launch window in late 2025 after multiple delays tied to technical reviews, launch pad work, and vehicle integration checks NASA Artemis. The launch date is not yet fixed, as NASA continues to finalize pre-flight testing, countdown demonstrations, and range availability at Kennedy Space Center in Florida.
As of the newest public updates, the mission remains on the agency's official launch manifest, with managers emphasizing that no specific launch date is set until the rocket, spacecraft, and ground systems complete required reviews and countdown rehearsals NASA Artemis I Mission Page. Any target launch window will be announced only after a Launch Readiness Review and Flight Readiness Review confirm that the vehicle, payload, range, and weather criteria are acceptable.
Mission Profile, Flight Duration, and Key Objectives
Primary Goals of the Artemis I Flight Test
Artemis I is designed to demonstrate the integrated performance of the SLS rocket and Orion crew capsule on an uncrewed lunar trajectory, validating systems such as the heat shield, avionics, navigation, and deep-space communications NASA Artemis I Mission Page. The flight will also deploy secondary payloads and test operations in a high-radiation lunar environment before future crewed missions.
Planned Trajectory and Return
The mission follows a trans-lunar injection profile, sending Orion beyond the Moon and into a distant retrograde orbit before returning to Earth for a high-speed reentry and Pacific Ocean splashdown NASA Artemis I Mission Page. The total mission duration is expected to span several weeks, with exact flight time depending on the actual launch date, trajectory adjustments, and orbital parameters.
Launch Vehicle, Contractor, and Program Cost Context
SLS Rocket and Prime Contractor Details
The Space Launch System rocket for Artemis I is built by Boeing under NASA's Exploration Production and Operations Contract, with the Orion spacecraft provided by Lockheed Martin and the European Service Module contributed by the European Space Agency NASA Artemis I Mission Page. Boeing, Lockheed Martin, and aerospace suppliers across the U.S. and Europe are responsible for integration, testing, and launch operations at Kennedy Space Center.
Budget and Program Spending Overview
NASA's Artemis program budget includes billions of dollars allocated across SLS, Orion, ground systems, and mission operations, with individual mission costs reported in agency financial documents and congressional budget justifications NASA Artemis I Mission Page. The exact per-mission cost for Artemis I is not publicly broken out in a single figure, but total program spending is tracked in NASA's annual budget requests and reports to Congress.
