How Much Would it Cost to Live on the Moon?

Establishing a permanent human presence on the Moon is technically possible, but transportation costs are the main obstacle. Moving people, equipment, and supplies approximately 234,000 miles (377,000 km) from Earth requires enormous expenditure, making taxpayer funding difficult to justify.

The cost estimate assumes four astronauts living on the Moon for one year before returning to Earth. The calculation uses NASA-developed technology and historical aerospace costs rather than assuming cheaper future spacecraft or transportation systems.

The Saturn V was the only rocket that had carried humans beyond low Earth orbit when the video was produced. NASA built 15 Saturn V rockets, all of which had been retired, making historical Apollo program costs the basis for the calculations.

A Saturn V could transport approximately 90,000 pounds of payload toward the Moon. Each launch cost $189 million in 1971 dollars, equivalent to approximately $1.123 billion in 2016 dollars, producing an estimated transportation cost of $12,500 per pound.

The initial launch-cost calculation suggests transporting an average American to the Moon would cost approximately $2 million. This uses an average body weight of 159 pounds (72 kg) and the Saturn V's estimated payload transportation cost, but excludes spacecraft development, landing equipment, and other essential expenses.

Developing the Saturn V cost approximately $6.4 billion, equivalent to $38 billion in 2016 dollars. Distributing that development expenditure across the rocket's 13 launches increases the estimated cost to slightly more than $4 billion per launch.

Including research and development raises Saturn V transportation costs to approximately $44,000 per pound, or $97,000 per kilogram. This substantially changes the economics compared with calculations using operational launch expenses alone.

Transporting equipment toward the Moon is considerably cheaper than delivering it safely to the lunar surface. A functioning settlement requires landing vehicles capable of transporting people, infrastructure, and supplies to the ground.

NASA's Apollo lunar lander program received approximately $18 billion in development and construction funding, expressed in 2016 dollars. Spread across 12 lunar landers, the estimated cost was $1.5 billion per vehicle, including development expenses.

Transporting four astronauts to the Moon and returning them to Earth is estimated to cost $11 billion. The proposed mission requires two lunar landers costing $1.5 billion each and two Saturn V launches costing approximately $4 billion each.

The crewed lunar landers must carry equipment and fuel for departure from the Moon. Unlike cargo vehicles that can remain on the surface, astronaut transportation systems require functioning ascent capabilities to support the return journey.

NASA designed an unmanned Apollo-era cargo lander called the LM Truck. The proposed vehicle could deliver approximately 11,000 pounds (5,000 kg) of supplies to the lunar surface without carrying astronauts.

A Saturn V could launch two LM Truck cargo vehicles simultaneously. Using this arrangement, the estimated transportation cost for delivering cargo directly to the lunar surface falls to approximately $318,000 per pound.

A purpose-built lunar base for four astronauts was estimated to require $20 billion in development and construction. The estimate comes from a study by the Center for Strategic and International Studies in Washington, DC.

Transporting the proposed lunar base would add another $4 billion, bringing the total to $24 billion. This assumes one Saturn V launch to deliver the necessary habitat infrastructure.

Bigelow Aerospace's proposed B330 inflatable spacecraft offered a potentially cheaper alternative to a purpose-built lunar base. The commercial habitat was designed for use in space and could conceivably be modified for operation on the lunar surface.

Bigelow Aerospace proposed renting the B330 for approximately $1.25 million per day. The video uses an estimated annual rental expense of $465 million for the astronauts' one-year mission.

Transporting the B330 to the lunar surface would cost approximately $14.5 billion. Weighing around 43,000 pounds, the habitat would require four LM Truck landings delivered through two Saturn V launches.

The B330 alternative would cost approximately $15 billion when transportation and annual rental are combined. This is substantially less than the $24 billion estimate for developing and delivering a dedicated lunar base, although lunar adaptation costs are not separately established.

Growing food on the Moon could reduce dependence on imported supplies. The University of Arizona developed a lunar greenhouse concept capable of producing approximately 5.5 pounds of food per day.

The proposed greenhouse planting arrangement consists of sweet potatoes, tomatoes, and strawberries. The video specifies 76% sweet potatoes, 16% tomatoes, and 10% strawberries, corresponding to approximately 4.3 pounds, 0.8 pounds, and 0.4 pounds of daily production respectively. The stated percentages total 102%, indicating a minor inconsistency in the proposed crop allocation.

Each greenhouse would produce approximately 1,800 calories of food daily. Sweet potatoes would supply roughly 1,675 calories, tomatoes approximately 65 calories, and strawberries approximately 60 calories.

Sweet potatoes provide most of the proposed greenhouse system's calories. At approximately 389 calories per pound, they offer substantially greater energy production by weight than tomatoes, at 81 calories per pound, or strawberries, at 151 calories per pound.

Four astronauts would require approximately 12,000 calories per day. Assuming each astronaut consumes 3,000 calories, the settlement would need the equivalent of 6.67 greenhouses operating at the projected productivity.

Seven greenhouses would be necessary to provide sufficient food. Rounding up from 6.67 greenhouses creates a small surplus that could serve as a reserve if food production fluctuates.

Each lunar greenhouse would weigh approximately one metric ton, or 2,200 pounds. Seven greenhouses would collectively weigh 15,400 pounds, resulting in approximately $4.9 billion in transportation costs at the estimated lunar cargo delivery rate.

The greenhouse system would require approximately 510 pounds of fertilizer annually. Each greenhouse needs 0.2 pounds per day, producing a combined daily requirement of 1.4 pounds for seven units.

Delivering the fertilizer would cost approximately $162 million. Although fertilizer represents relatively little cargo weight, the exceptionally high lunar delivery cost makes even this routine agricultural supply expensive.

The International Space Station demonstrates how recycling can reduce water requirements in space. Its water recovery systems reclaim and purify water from sources including condensation, sweat, showers, and urine.

Without recycling, four astronauts would require approximately 40,000 pounds of water for one year. Delivering that quantity to the lunar surface would cost approximately $12.7 billion.

Water recycling could reduce the astronauts' annual imported water requirement to 5,110 pounds. This represents a substantial saving compared with continuously importing fresh water.

The proposed greenhouses would require another 6,920 pounds of water. Agricultural production therefore adds a significant requirement that must be included alongside the astronauts' personal consumption.

The settlement's combined annual water requirement would be approximately 12,030 pounds. This includes 5,110 pounds for the astronauts after recycling and 6,920 pounds for food production.

Transporting the required water would cost approximately $3.825 billion. Recycling makes the proposed settlement substantially less expensive than a system dependent entirely on imported water.

An astronaut performing moderate physical activity requires approximately 1.85 pounds of oxygen daily. Four astronauts would consume around 7.4 pounds per day, totaling approximately 2,701 pounds over one year.

Transporting all the astronauts' oxygen from Earth would cost approximately $860 million. This calculation assumes no oxygen contribution from the settlement's agricultural infrastructure.

The seven greenhouses would collectively generate approximately 5.25 pounds of oxygen daily through photosynthesis. Each greenhouse is expected to produce around 0.75 pounds per day, offsetting most of the astronauts' breathing requirements.

Greenhouse oxygen production would reduce imported oxygen requirements to approximately 2.15 pounds daily. Over one year, the settlement would need around 785 pounds of additional oxygen transported from Earth.

Combining imported oxygen with greenhouse production reduces the estimated oxygen transportation cost to $250 million. The arrangement saves approximately $610 million compared with importing the entire annual oxygen supply.

The video rejects developing a dedicated oxygen regeneration system for the proposed mission. Its reasoning is that developing, manufacturing, and delivering sufficiently capable equipment would cost more and introduce greater risk than transporting the remaining required oxygen.

A compact nuclear fission reactor is proposed as the settlement's electricity source. The reactor would operate on the lunar surface and provide power for the astronauts and their equipment.

NASA estimated that a lunar nuclear power system could be developed, flight-tested, and delivered for approximately $1.4 billion. At the time described, NASA had proposed the system but had not developed it.

The video's overall estimate for supporting four astronauts on the Moon for one year is approximately $36 billion. The figure combines astronaut transportation, an inflatable habitat, agricultural equipment, fertilizer, water, oxygen, and nuclear power infrastructure, using the video's historical cost assumptions.

The estimated $36 billion expenditure represents approximately $98 million per day. Expressed in shorter intervals, the video calculates roughly $4.1 million per hour, $68,300 per minute, and $1,138 per second.

The estimate is deliberately approximate rather than a finalized NASA mission budget. It combines historical development costs, proposed systems, commercial rental prices, and theoretical resource requirements. Several technologies would need modification or development before they could support the proposed settlement.

Research and development expenses account for a substantial portion of the projected mission costs. The calculation assigns historical development expenditure to individual Saturn V launches and lunar landers because these systems are retired, substantially increasing their estimated prices.

Transportation costs affect nearly every other component of the settlement. Habitat equipment, greenhouses, fertilizer, water, and oxygen become exceptionally expensive primarily because their mass must be transported from Earth and landed safely on the Moon.

Food production provides benefits beyond feeding astronauts. The greenhouses simultaneously produce food and oxygen, reducing the quantity of life-support supplies that must be imported, although they increase the requirements for equipment, fertilizer, and water.

The economics of lunar habitation could improve considerably with more capable commercial launch providers. The video anticipates that a serious NASA colonization effort would probably take place decades later, when space transportation could be substantially cheaper.

Spaceflight Industries was offering lunar-orbit cargo transportation at approximately $10 million per 220 pounds (100 kg). The cited commercial price illustrates the potential for lower transportation expenses, although delivery to lunar orbit is not equivalent to landing cargo on the lunar surface.

Lower transportation prices could eventually make commercial activity on the Moon economically viable. The video identifies resource extraction and tourism as possible industries that could benefit from cheaper access to the lunar surface.

Elon Musk was expected to announce SpaceX's Mars transportation plans on the video's publication date. The anticipated announcement included a large rocket intended to transport substantially heavier payloads than earlier spacecraft.

The proposed SpaceX rocket was expected to carry as much as 220,000 pounds of payload to Mars. The video presents this capacity, alongside anticipated reductions in launch costs, as a possible breakthrough in making Martian settlement financially feasible.

Commercial space transportation is presented as the factor most likely to change the economics of extraterrestrial settlement. More efficient and higher-capacity rockets could reduce the enormous transportation expenses underlying the $36 billion lunar mission estimate.

The video argues that lunar settlement could become a worthwhile investment despite its extraordinary initial cost. Its justification extends beyond immediate commercial returns to the possibility of developing technologies necessary for humans to survive away from Earth.

Environmental deterioration on Earth is presented as a long-term reason to develop off-world settlements. The video suggests that learning to sustain human life on the Moon, Mars, or another celestial body could become crucial if Earth eventually becomes unable to support human civilization.

The Moon is treated as an early testing ground for humanity's ability to live beyond Earth. Establishing a functioning lunar settlement would provide experience in transportation, shelter, food production, resource recycling, oxygen management, and power generation that could inform future settlements elsewhere in the Solar System.
