Complete Timeline

Humanity's path to returning to the Moon: all milestones of the Artemis program from the first test mission to the landing.

November 16, 2022

Artemis I - Launch

First flight of the Space Launch System (SLS) and Orion capsule. Uncrewed mission to test all systems.

Completed
November 21, 2022

Artemis I - Lunar Flyby

Orion performed a close flyby of the Moon at just 130 km from the surface, entering a distant retrograde orbit.

Completed
December 11, 2022

Artemis I - Splashdown

Orion returned to Earth after 25.5 days in space, traveling over 1.4 million miles. Splashdown in the Pacific Ocean.

Completed
October 13, 2024

Starship IFT-5 - First Booster Catch

SpaceX catches the Super Heavy booster for the first time using the launch tower's mechanical arms ("Mechazilla"). A historic moment for space reusability.

Completed
2023-2026

Starship HLS Development

SpaceX continues Starship testing, the vehicle that will serve as the lunar lander for Artemis III. 11 integrated flight tests completed by October 2025. Orbital refueling demo expected mid-2026.

In Progress
2024-2026

AxEMU Spacesuits

Axiom Space is developing the new spacesuits for lunar extravehicular activities. Currently undergoing thermal vacuum testing.

In Development
October 2025

Artemis II SLS Assembly Complete

SLS rocket stacking for Artemis II completed at Kennedy Space Center's VAB: boosters, core stage, upper stage, and Orion capsule with launch abort system.

Completed
April 2025

Gateway - HALO Module in US

The HALO habitation module (Habitation and Logistics Outpost), built by Thales Alenia Space, arrives in the United States at Northrop Grumman's facility for final assembly before launch.

Completed
April 2026 (planned)

Artemis II - First Crewed Mission

Four astronauts (3 NASA + 1 CSA) will orbit around the Moon without landing. Testing life support systems with crew.

Crew: Reid Wiseman (Commander), Victor Glover (Pilot), Christina Koch, Jeremy Hansen (CSA)

In Preparation
2028 (no earlier than)

Artemis III - Return to the Moon

Two astronauts will walk on the lunar surface at the South Pole, the first time since 1972. Includes the first woman on the Moon. Delayed from September 2026 due to Starship HLS development and Orion heat shield issues.

Planned
2027 (planned)

Gateway Launch (PPE + HALO)

The first two modules of the Lunar Gateway — the Power and Propulsion Element (PPE) and the HALO module — will launch together on a Falcon Heavy to lunar orbit.

Planned
2028+

Artemis IV and Beyond

Subsequent missions with Gateway as an orbital base. Goal: permanent lunar presence and preparation for Mars.

Future
2030s

Toward Mars

Technologies and experience gained with Artemis will prepare humanity for the first human missions to Mars.
