The NASA Artemis program has achieved remarkable milestones in its journey to return humans to the Moon and beyond. In the past five years (2018-2023), these are the five most critical milestones that have shaped the program’s progress.
Completion of the SLS and Orion Spacecraft: The Space Launch System (SLS), NASA’s most potent rocket, was completed and tested in 2021. This marked a critical milestone as the SLS is designed to carry the Orion spacecraft, astronauts, and supplies for deep-space missions. Orion, too, saw significant advancements, with rigorous testing and validation completed. The finalization of these two systems is pivotal for the Artemis missions and our overarching lunar ambitions.
Artemis I Successful Uncrewed Mission: Launched in late 2021, the Artemis I mission was an uncrewed flight to test the combined performance of the SLS and the Orion spacecraft. This mission proved the integrated system’s readiness to move to the next level – sending astronauts on lunar missions. The success of Artemis I was a significant achievement, showcasing the combined effectiveness of the SLS and Orion spacecraft and propelling NASA forward in its program timeline.
Development of Lunar Gateway: The development of the Lunar Gateway, a small spaceship in orbit around the Moon, has progressed substantially over the last five years. The Lunar Gateway will serve as a science laboratory, a testbed for new technologies, and a hub for operations. It’s designed to facilitate long-term lunar exploration for human and robotic missions. In 2022, the Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO) segments were launched and joined in lunar orbit, marking a key achievement in this ambitious project.

Artemis II – The First Crewed Mission Around the Moon in the 21st Century: In 2023, Artemis II was successfully launched as the first crewed mission aboard Orion, marking the first time humans had traveled beyond Low Earth Orbit since 1972. The mission, a multi-day journey around the Moon, marked a significant moment in human space exploration, confirming the safety and reliability of NASA’s crewed deep-space capabilities and setting the stage for future lunar landings.
Global Partnerships and Lunar Accords: Lastly, NASA’s Artemis program has significantly expanded international partnerships. The Artemis Accords, signed by multiple nations, promote peaceful exploration and help share the costs and benefits of lunar exploration. Securing these partnerships represents a significant milestone for a sustainable return to the Moon and for developing legal and diplomatic frameworks.
These achievements mark significant advancements toward NASA’s goal of returning to the Moon, setting the stage for sustainable lunar exploration, and paving the way for future manned missions to Mars. The Artemis program has proven to be a beacon of human ambition and curiosity, uniting the world in the quest to push NASA’s boundaries and explore the universe beyond our home planet. The future of space exploration is promising, and the past five years have proven that we’re more than capable of turning the seemingly impossible into reality.
