Artemis Mission Plans

Artemis 1 Launch Date and Mission

Artemis 1 Launch Date: November 2021 (successfully launched)

Artemis 1, the first mission in the Artemis program, marked a significant milestone in NASA's lunar exploration efforts. This uncrewed mission aimed to test the Space Launch System (SLS) rocket and the Orion spacecraft. The mission's success was crucial for ensuring the safety and reliability of the hardware and systems before sending astronauts on future missions.

Artemis 2 Launch Date and Mission

Artemis 2 Launch Date: November 2024

Artemis 2 will be the first crewed mission in the Artemis program. This mission will take astronauts around the Moon and back to Earth, testing the Orion spacecraft's life support systems and ensuring all components function correctly with a human crew on board. This mission will pave the way for more complex lunar missions in the future.

Artemis 3 Launch Date and Mission

Artemis 3 Launch Date: December 2025

Artemis 3 is the mission that will see astronauts return to the lunar surface for the first time since 1972. The mission aims to land astronauts on the Moon's South Pole, a region believed to contain water ice, which is vital for future exploration and potential colonization. The Artemis 3 mission will also include extensive scientific research and exploration activities.

Artemis, NASA, and the Space Station

The Artemis program, managed by NASA, involves international and commercial partnerships. One key element of this collaboration is the Lunar Gateway, a space station orbiting approximately 250,000 miles above the Earth. The Gateway will serve as a staging point for lunar missions, providing a platform for scientific research and a base for astronauts before they descend to the lunar surface.
