NASA launches uncrewed Artemis I mission around the Moon

NASA launched the uncrewed Artemis I mission from Kennedy Space Center on 16 November 2022. The first Space Launch System rocket placed the Orion spacecraft on a trajectory toward the Moon, beginning an integrated test of the heavy-lift launcher, capsule and ground systems.

Orion travelled into a distant retrograde lunar orbit, passed farther from Earth than any spacecraft designed to carry humans had previously flown, and returned for a high-speed atmospheric entry. Sensors and mannequins gathered data on radiation, loads and the crew environment; no astronauts were aboard.

The launch followed technical delays, weather disruptions and years of programme development. A successful liftoff did not validate every mission objective in advance. Splashdown, heat-shield performance and post-flight inspection were later evidence needed before crewed flight.

Artemis is intended to support sustained human exploration of the Moon and prepare technologies for more distant missions. Programme schedules, costs and architecture have changed, so the 2022 test should not be portrayed as a fixed guarantee of a particular landing date.

Launch telemetry and NASA mission records establish the event. This article distinguishes Artemis I from Apollo-era crewed missions and from later Artemis flights. Its milestone was the first end-to-end flight of a new system, with risk deliberately accepted on an uncrewed mission before people would use it. The launch alone did not certify the spacecraft for a crew.
