Artemis 1 Launch Time Overview
Artemis 1 launched from Kennedy Space Center in Florida on November 16, 2022. The Space Launch System rocket lifted off at 1:47 a.m. EST, carrying the uncrewed Orion spacecraft on a roughly 25-day test flight around the Moon and back.
Artemis 1 Countdown and Launch Window
NASA used a specific launch window to align trajectories and mission constraints. The countdown proceeded through standard holds and built-in pauses, with controllers verifying rocket, spacecraft, and range systems before the final ignition sequence.
Artemis 1 Mission Timeline and Significance
After launch, Orion separated from the rocket, deployed solar arrays, and traveled outward via the interim cryogenic propulsion stage. The mission tested deep-space navigation, communication, and thermal protection systems, supporting future crewed Artemis flights.
