NASA wants to build a base on the Moon by the 2030s – how and why it plans to build up to a long‑term lunar presence

The next U.S. trip to the Moon isn’t about planting a flag. It’s about learning how to live and work there.

NASA has just reset its Artemis program, marking a clear strategic shift: Space exploration is moving away from a race to achieve milestones and toward a system built on repeated operations, a sustained presence and lunar infrastructure that could become part of the technology networks we rely on here on Earth.

That shift is reflected in newly announced plans to invest billions of dollars in building a long-term lunar base, with habitats, power systems and surface infrastructure designed to support ongoing human activity. The message? Humans have already normalised travel to space. The next step is normalising living beyond Earth.

Artemis is NASA’s plan to return people to the Moon with the goal of staying. Unlike the short Apollo missions of the 1960s and 1970s, it consists of increasingly complex missions: flying around the Moon, landing on its surface and eventually establishing a base near the lunar south pole. The program aims to create a reliable way for humans to live and work there, develop technologies useful on Earth and prepare for the journey to Mars.

Rather than moving straight from the upcoming Artemis II crewed lunar flyby to a surface landing, the new road map adds an intermediate mission in 2027. Astronauts will test docking, life-support systems and communications with commercial lunar landers from SpaceX and Blue Origin, but in low Earth orbit, the region roughly 100 to 1,200 miles (160 to 2,000 kilometres above Earth’s surface, where rescue remains possible.

The first landing near the lunar south pole is now targeted for 2028. This timeline may sound delayed, but in reality, it has been deliberately reset to prioritise building reliable systems that can operate long into the future over speed.

As a professor of air and space law, I’ve been watching these developments closely. The United States is still in a race – particularly with China – but it is choosing to compete on its own terms. Rather than chasing the fastest possible landing, NASA is focused on building a system that can support repeated missions and a lasting human presence.

From sprint to system

The original Artemis plan aimed to leap quickly from test flights to a crewed landing while simultaneously developing new rockets, spacecraft and landing systems. That approach carried risk. Artemis I, an uncrewed mission, flew successfully in 2022. After a few delays, Artemis II is now nearing launch, with windows planned for early April 2026. But the further jump to a safe and reliable landing remains significant.

NASA’s new road map slows the transition deliberately. Instead of stand-alone milestones, NASA is now building a sequence of repeatable steps to gain hands-on experience.

This change includes a substantial new investment, with a multiphase plan for a lunar base with habitats, power systems and the surface infrastructure needed for a long-term human presence on the Moon. Consistent launch cadence and repeatable operations are how teams develop the expertise needed for safe, reliable spaceflight and eventually for travelling to Mars.

This shift is reflected in the decision to pause the planned lunar Gateway station, a small space station intended to orbit the Moon, and prioritise infrastructure on the lunar surface itself, where astronauts will live, work and build over time.

The new changes also emphasise a shifting role for commercial companies. SpaceX’s and Blue Origin’s lunar landers are integrated into the mission architecture.

The 2027 test mission, for example, will practice docking between crewed spacecraft and new commercial lunar landers in low Earth orbit. NASA is coordinating a network of public and private partners rather than running a single government-run Apollo-like program.

This method spreads risk across partners, lowers costs and speeds development, though success now depends on multiple players working reliably together.

Law follows activity

NASA’s road map is not just about lowering technical risk. It is also about shaping the future environment of lunar activity.

International space law, including the 1967 Outer Space Treaty, sets out broad principles to guide space activities, like avoiding harmful interference with others’ activities. But those rules only gain real meaning through repeated, coordinated activity, especially on the lunar surface, where desirable landing sites are limited.

Countries and companies that maintain a sustained presence on the Moon will shape the practical expectations everyone will share while living and working on the Moon. One-off demonstrations, like lunar landings, don’t shape lunar activity like continued operations would.

Why this matters – even if you never go to space

It would be easy to see these changes as purely technical, but they are not. The structure of a space program shapes what technologies are developed, how industries grow and which countries influence how space is used. Technologies developed for sustained lunar activity, including life-support systems, energy storage and advanced communications, have found applications on Earth, from medicine to disaster response.

There are economic effects as well. The Artemis program supports jobs across the United States and among its international partners. It helps build industries that extend far beyond NASA itself.

And there is a strategic dimension. As more countries and companies operate in space, the question is no longer just who arrives first, but who helps define how activity is carried out. Over time, that presence will likely become part of the infrastructure that supports daily life on Earth.

Communications, navigation, supply chains and scientific data already depend on space-based systems. As activity expands to the Moon, facilities there, from energy systems to communications relay systems that transmit data and signals back to Earth, will become integrated into those networks. What is built on the Moon will not sit apart from life on Earth, but increasingly function as an extension of it.

The Moon is becoming a place where infrastructure, industry and rules and expectations for how humans operate there are already beginning to take shape. NASA’s updated plan signals that the United States intends to be present there consistently.

The updates to the Artemis program are a statement about how the United States intends to engage in the next phase of space exploration. Rather than pursuing a single dramatic landing, the U.S. is committing to the steady, repeatable work of building a lasting foothold on the Moon, and redefining humanity’s relationship with space itself.
