Artemis I

NASA’s uncrewed test flight of the SLS rocket and Orion spacecraft, completed in November 2022 as part of the Artemis program.

Completed Verified 2026-10-02

Overview

Nature and context

Artemis I was an uncrewed NASA mission and a test flight of the Space Launch System (SLS) rocket and the Orion spacecraft. NASA places the mission within Artemis, a program intended to conduct increasingly challenging lunar missions, advance scientific discovery, and build on capabilities for future human missions to Mars. Artemis I was a test step within that wider framework; it is distinct from the program as a whole and from later missions that NASA’s page describes as planned.

Documented objectives

According to NASA’s page Moon to Mars | NASA’s Artemis Program, Artemis I was successfully completed in November 2022. The mission marked the first launch of the SLS rocket using new exploration ground systems. It also evaluated Orion’s systems without astronauts and without the critical life-support systems planned for future crewed flights. The source presents these as features and objectives of the test flight. The available material does not provide a detailed list of individual tests, measurements, incidents, or technical conclusions.

Scope and interpretation

The uncrewed nature of the mission matters when interpreting what it could demonstrate. The source says that spacecraft systems were evaluated, while also specifying that astronauts and the critical life-support systems planned for future crewed missions were not aboard. The evidence therefore does not support saying that Artemis I fully validated those life-support systems under crewed flight conditions. NASA describes the flight as part of a broader campaign, rather than as a mission separate from the program’s later objectives.

Sources and limits

This profile is based on NASA’s official page Moon to Mars | NASA’s Artemis Program, consulted on 1 October 2026. The page gives November 2022 but the supplied extract does not state exact launch and return dates, mission duration, a complete flight profile, or quantitative results. It also provides no administrative identifier separate from the name “Artemis I.” Those details are therefore not supplied here. This account is limited to the mission’s nature, context, and objectives explicitly supported by the source.
