Why We're Going Back to the Moon
More than five decades after Apollo 17's final lunar footsteps in 1972, NASA's Artemis program represents humanity's most ambitious return to the Moon — and this time, the goal is to stay. Unlike the Apollo missions, which were largely driven by Cold War competition, Artemis is built around long-term scientific exploration, international cooperation, and laying the groundwork for eventual crewed missions to Mars.
What Is the Artemis Program?
Artemis is NASA's multi-phase lunar exploration program, developed in partnership with the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), the Canadian Space Agency (CSA), and numerous commercial partners including SpaceX and Lockheed Martin.
The program takes its name from the Greek goddess of the Moon and twin sister of Apollo — a nod to its predecessor while signaling a new era, one that aims to land the first woman and first person of color on the lunar surface.
Key Missions at a Glance
- Artemis I (2022): An uncrewed test flight of the Space Launch System (SLS) rocket and Orion capsule. The mission successfully flew around the Moon and returned to Earth, validating the hardware.
- Artemis II: The first crewed flight of the Orion capsule, taking astronauts on a loop around the Moon without landing — a repeat of the Apollo 8 approach to build crew confidence.
- Artemis III: The landmark mission — crewed lunar landing, targeting the South Pole region of the Moon.
- Gateway Station: A planned lunar orbital outpost that will serve as a staging point for surface missions, built jointly with international partners.
Why the Lunar South Pole?
The choice of the South Pole as a landing target isn't arbitrary. Permanently shadowed craters in the region are believed to harbor significant deposits of water ice — a resource that could be converted into drinking water, breathable oxygen, and even rocket propellant (hydrogen and oxygen). This concept of in-situ resource utilization (ISRU) is central to making long-duration lunar and deep-space missions sustainable.
The Science Agenda
Beyond exploration milestones, Artemis carries a rich scientific agenda:
- Studying the geological history of the Moon to better understand the early solar system.
- Investigating the origin and extent of lunar water ice deposits.
- Testing technologies for life support, radiation protection, and habitat construction in deep space.
- Deploying scientific instruments and rovers to conduct long-term monitoring.
Commercial Partners and the New Space Economy
One of the defining features of Artemis is the heavy involvement of commercial companies. SpaceX's Starship was selected as the Human Landing System (HLS) for early missions, while other companies are developing lunar rovers, communication relays, and cargo delivery services under NASA's Commercial Lunar Payload Services (CLPS) program. This commercial model aims to reduce costs and stimulate a broader lunar economy.
The Road to Mars
NASA consistently frames the Moon as a proving ground for Mars. The technologies, operational procedures, and life support systems tested under Artemis will directly inform how astronauts can survive the 7–9 month journey to Mars and operate on its surface. The Moon, just three days away, is the ideal testbed — close enough for emergency returns, yet far enough to present real deep-space challenges.
The Artemis program represents a genuine inflection point in human spaceflight — one where the Moon transitions from a destination to a waypoint, and the cosmos begins to feel a little more within reach.
