Lunar rehearsal: Your mission guide to Artemis I

November 2021

NASA will conduct an uncrewed lunar practice run to test its Space Launch System rocket before it carries astronauts. This upcoming mission, Artemis I, will be a precursor to a similar crewed flight to be followed by a lunar landing targeted for 2024. Depending on the position of the Earth and moon at launch, an SLS will blast an unoccupied Orion capsule on a 26- or 42-day trip around the moon and back.

Follow along with our timeline of the major milestones as the Artemis I flight unfolds.
