The Lunar Economy Is Pricing the Crew at Less Than One Percent

Summary

Deloitte’s Building the Lunar Economy estimates that a sustained presence on and around the Moon could be worth between $343 billion and $566 billion from 2026 to 2050.¹ It is one of the most thorough attempts yet to put numbers on lunar activity, and we agree with much of it.

We disagree with one part of the model. Life support, the category that covers keeping people alive and healthy, is valued at $2.4 billion to $3.5 billion over the same period. That is less than one percent of the total, in a report whose own interviews describe life support as the least mature part of the architecture.

What the report gets right

The report is right that the Moon is shifting from a story of flags and footprints to one of infrastructure, and that energy, communications, transportation, construction and computing are beginning to connect into a system. It is also candid about the human side. It notes that radiation remains one of the largest unresolved biological threats on the surface, that the ISS recovers up to 98 percent of water but only about half of oxygen from CO₂, and that medical care beyond Earth remains largely unsolved.¹

Where we disagree

Those observations do not carry through to the numbers. In the report’s accelerated scenario, transportation is valued at $205.7 billion and life support at $3.5 billion.¹

A model that values getting to the Moon sixty times more than surviving on it is measuring hardware, not presence. A sustained human presence is the premise of the whole report. If crews cannot stay healthy for months at a time, most of the other categories do not materialize at the scale projected.

Why the crew is the constraint

Launch costs are falling under commercial competition. The systems that keep a crew healthy have not changed at the same pace. In weightlessness, astronauts lose bone mineral density at about 1 to 1.5 percent per month in weight-bearing bones, and NASA’s Human Research Program tracks a long list of risks to crew health and performance, several with mechanisms that are still not fully understood.

On the Moon, crews will live for months in partial gravity, whose effects on the body are largely unmeasured. Life support there is more than air and water. It includes medical care, sleep, exercise, behavioral health, waste management and the design of the habitat itself. Each of these is a product category with its own buyers.

What a fuller model would include

We would value the lunar economy’s human systems along four lines that the current model either compresses into life support or leaves out:

• Crew health monitoring and medical care, including imaging, diagnostics and in-mission treatment.
• Countermeasures for bone, muscle, cardiovascular and sleep changes.
• Habitation and soft architecture: interiors, crew quarters and inflatable volumes designed for months-long stays.
• Crew health data: the longitudinal record of how bodies perform in altered gravity, and the models built on it.

Valued properly, the human layer would be a meaningful share of the lunar economy rather than a rounding error. That is where Stellar Amenities Lab works.
