For most of human history, the moon has been more than a distant light in the night sky. It has functioned as a clock, a guide and a deity—a celestial constant that helped early civilizations organize their existence. But as NASA prepares the Artemis II mission to return astronauts to the lunar system, the nature of that connection is shifting. We are moving from an era of observation and brief visitation toward a permanent, sustainable presence.
This shift represents more than a technical milestone. it is a psychological pivot. Although the Apollo missions of the 20th century proved that humans could reach the lunar surface, the Artemis missions will reframe humanity’s relationship with the moon by treating it not as a destination to be visited, but as a companion world essential to our survival and future.
Science writer Rebecca Boyle explores this evolving bond in her book, “Our Moon: How Earth’s Celestial Companion Transformed the Planet, Guided Evolution, and Made Us Who We Are” (Penguin Random House, 2025). Boyle argues that the moon is not merely a satellite, but an active participant in Earth’s history, shaping the planet’s climate, geologic stability, and the particularly trajectory of biological evolution.
For this generation, the moon is becoming a laboratory for the next stage of human expansion. The transition from the “flags and footprints” approach of the 1960s to the goal of a permanent lunar base marks a fundamental change in how we perceive our place in the solar system.
The moon as humanity’s first clock
The earliest human relationships with the moon were born of necessity. Before the invention of mechanical timekeeping, the lunar cycle provided the most reliable method for tracking the passage of time and planning for the future—a cognitive leap that Boyle identifies as a uniquely human characteristic.
This practical utility embedded the moon into the fabric of global culture. Lunar-based calendars developed independently across every continent. Today, this legacy persists in the Hebrew calendar, the Islamic lunar calendar, and the luni-solar systems used across Asia, which continue to dictate the timing of major cultural events like the Lunar Modern Year in China.
Beyond timekeeping, the moon served as one of the earliest personified deities in human religion. While the Apollo missions transformed the moon into a “real place” of rock and dust, Boyle suggests that the Artemis era offers an opportunity to reintegrate these cultural perspectives with modern science, recognizing the moon not just as a piece of geology, but as a partner in the human story.
From visitation to habitation
The Apollo era was defined by the triumph of arrival. By landing humans on the surface and bringing lunar samples back to Earth, NASA provided a transformative understanding of the moon’s composition and its relationship to Earth’s early history. However, those missions were essentially sprints—short-term excursions that left the moon as a distant, alien territory.
The Artemis program is designed as a marathon. By establishing the Artemis Base Camp and the Lunar Gateway—a small space station that will orbit the moon—NASA aims to create a sustainable human presence. This transition fundamentally changes the moon’s role from a scientific curiosity to a functional extension of human civilization.
| Feature | Apollo Era (1961–1972) | Artemis Era (Current) |
|---|---|---|
| Primary Goal | Lunar landing and return | Sustainable long-term presence |
| Infrastructure | Single-use landing craft | Lunar Gateway & Surface Base |
| Crew Diversity | Male, U.S. Citizens | First woman and person of color |
| Scope | Short-term exploration | Resource utilization (e.g., ice) |
This new approach allows scientists to study the moon over longer timescales. The focus has shifted toward identifying resources, such as water ice in permanently shadowed regions of the lunar south pole, which could provide life support and fuel for deeper space exploration.
The ‘Companion World’ hypothesis
One of the most significant reframings provided by the Artemis missions is the scientific recognition of the moon as a “companion world.” Unlike the moons of Mars, which Boyle describes as “potatoes that just fly around Mars,” Earth’s moon is disproportionately large relative to its planet. This size and distance are not accidental; they are critical to the conditions that allowed complex life to emerge on Earth.
The moon’s gravitational pull stabilizes Earth’s axial tilt, preventing wild swings in climate that would make the planet uninhabitable. It drives the tides, which many scientists believe played a crucial role in the transition of life from the oceans to the land. In this sense, the moon is not just a neighbor, but a biological prerequisite.
Boyle notes that it is “sort of this generation’s moment to understand in a new way the connection between the moon and this planet and sort of reframe its importance to human history.” By returning to the moon, we are not just exploring a satellite; we are investigating the mirror that reflects Earth’s own origin story.
The invisible effort of exploration
While the launch of a rocket is a moment of high visibility, the reality of the Artemis program is one of glacial persistence. The missions are the result of decades of incremental progress, involving thousands of engineers, scientists, and policymakers.
There is a tendency to take the capabilities of NASA for granted, but the sheer scale of the logistics—from the Space Launch System (SLS) to the Orion spacecraft—highlights the immense human dedication required to leave Earth. Boyle emphasizes that these missions are evidence of work happening on long timescales, requiring moral and financial support that transcends political cycles.
The goal of a lunar base is not merely a display of power, but a necessary stepping stone. The moon serves as a proving ground for the technologies—radiation shielding, closed-loop life support, and autonomous mining—that will be required for the eventual human journey to Mars.
The next critical checkpoint in this journey is the Artemis II mission, currently scheduled for no earlier than September 2025. This mission will send a crew around the moon and back, marking the first time humans have left Earth’s orbit since 1972. This will be followed by Artemis III, which aims to land the first woman and first person of color on the lunar surface, currently targeted for no earlier than September 2026.
As we move closer to these dates, the moon will cease to be a symbol of the distant past and become a tangible part of our immediate future. We are no longer just looking up at the moon; we are preparing to live among it.
