How much has the Artemis program cost so far?

NASA's Office of Inspector General projected in November 2021 (Report IG-22-003) that the Artemis program cost would reach approximately $93 billion cumulatively across fiscal years 2012 through 2025. That projection spans the early development of the Space Launch System rocket, the Orion crew spacecraft, supporting Exploration Ground Systems, and initial lunar lander contracts. Neither NASA nor oversight agencies have published an audited cumulative program cost that projects beyond fiscal year 2025.

Why does each Artemis launch cost $4 billion?

NASA's Office of Inspector General calculated that the production and operations cost of a single Space Launch System and Orion flight system averages approximately $4.1 billion per launch for missions Artemis I through IV. That sum includes the SLS booster stages, solid rocket boosters, four RS-25 engines, Orion capsule integration, and ground processing through Exploration Ground Systems at Kennedy Space Center. The OIG characterized this recurring launch cost as unsustainable for long-term lunar exploration.

Is the Artemis program a waste of money?

Critics point to inefficiencies documented by government oversight bodies, including roughly $5.9 billion spent on Artemis-related contracts and hardware that were canceled after early-2026 program restructurings and may never fly. Additionally, the Government Accountability Office reported in July 2026 that Orion spacecraft overruns accounted for most major-project cost growth across NASA. Supporters counter that Artemis has established active deep-space flight hardware, including the successful Artemis II crewed lunar flyby in April 2026.

How much more does Artemis cost than the Apollo program?

The Apollo program cost substantially more in inflation-adjusted dollars than Artemis has spent to date. According to The Planetary Society, Project Apollo cost $25.8 billion between 1960 and 1973, which equals roughly $309 billion in 2025-adjusted dollars, or $338 billion when including precursor programs like Gemini. By comparison, NASA's projected Artemis program cost through fiscal year 2025 was approximately $93 billion, less than one-third of Apollo's inflation-adjusted total commitment.

What Artemis hardware got canceled, and why?

A June 2026 NASA Office of Inspector General memo found NASA spent approximately $5.9 billion on hardware and contracts canceled after a February to March 2026 architecture restructuring. The most prominent canceled system was Boeing's Exploration Upper Stage for the SLS Block 1B rocket. That contract grew from $962 million to nearly $2 billion before NASA issued a stop-work order in March 2026, with the OIG projecting completion costs would have hit $3.7 billion.

Did NASA overspend on the Orion capsule specifically?

The Orion spacecraft has driven major budget increases across NASA's portfolio. In July 2026, Government Accountability Office Report GAO-26-108556 found the Orion program alone accounted for over half of NASA's major-projects annual cost overruns and nearly 75 percent of their cumulative overruns. Orion logged a $261 million annual overrun tied to a seven-month schedule slip on the Artemis II mission, which delayed that flight from September 2025 to April 2026.

Artemis Program Cost: $93B Total, $4.1B per Launch

The Artemis program cost reaches approximately $93 billion across fiscal years 2012 through 2025, according to projections published by NASA’s Office of Inspector General in Report IG-22-003. Oversight audits indicate that producing and launching the Space Launch System rocket and Orion capsule averages $4.1 billion per mission for Artemis I through IV. That spending pace prompted the space agency’s internal watchdogs to label the program’s recurring launch costs unsustainable.

Public criticism of the Artemis program budget intensified following a series of mid-2026 federal oversight reports detailing major schedule slips, contract terminations, and billions spent on hardware that will never fly. A June 2026 watchdog memo revealed roughly $5.9 billion in spending on abandoned Artemis hardware, while a July 2026 congressional audit confirmed that the Orion spacecraft alone generated over half of the cost overruns across NASA’s major project portfolio.

What Artemis Has Cost So Far

The Artemis program cost is projected at approximately $93 billion from fiscal year 2012 through fiscal year 2025. That estimate comes from NASA Office of Inspector General (OIG) Report IG-22-003, released on November 15, 2021. The figure represents cumulative funding directed toward deep space exploration systems over a 14-year period, covering early development of the Space Launch System (SLS), the Orion crew spacecraft, and associated ground infrastructure.

Report IG-22-003 determined that the production and operations cost of a single SLS and Orion flight stack runs approximately $4.1 billion per launch. That per-flight baseline applies to the first four missions: Artemis I, Artemis II, Artemis III, and Artemis IV. In that review, the OIG characterized this recurring launch rate as unsustainable for long-term lunar operations. Media coverage, including reporting from CBS News, brought widespread public attention to these recurring launch liabilities.

Neither NASA nor independent watchdogs have published a verified cumulative Artemis program budget projection that extends past fiscal year 2025. Anyone assessing the total investment must look at individual program elements, contract modifications, and specific audit releases rather than an official lifecycle price tag. For an operational overview of the missions funded by this spending, see our guide explaining the Artemis program.

Where the Money Goes

The $4.1 billion per-launch price tag covers the physical flight vehicles, engine manufacturing, capsule integration, and operational ground processing. Building and launching a single deep space vehicle requires capital spread across thousands of defense and aerospace contractors.

NASA spends this money across five major hardware and operational categories:

SLS Core Stage and Avionics: The central 212-foot core stage built by Boeing represents a major component of the rocket’s hardware costs.
RS-25 Liquid Engines: Each flight expends four Aerojet Rocketdyne RS-25 cryogenic engines originally designed for reuse on the Space Shuttle.
Solid Rocket Boosters: Northrop Grumman provides the two five-segment solid rocket boosters that flank the core stage during ascent.
Orion Spacecraft: Lockheed Martin manufactures the crew capsule, while the European Space Agency supplies the European Service Module for propulsion, water, and air.
Exploration Ground Systems (EGS): Ground processing encompasses crawler-transporters, mobile launchers, and pad infrastructure at Kennedy Space Center.

None of the primary flight hardware for the SLS and Orion stack can be recovered or reused. Every single mission discards four RS-25 liquid engines, two solid rocket booster casings, the central core stage, the interim cryogenic second stage, and the Orion service module in the ocean. This expendable launch architecture prevents NASA from amortizing hardware construction over multiple flights. A breakdown of the rocket’s individual stages appears in our explainer covering the SLS rocket.

By comparison, private commercial companies design modern orbital vehicles around recovery and reuse. Commercial operators publish transparent launch rates or target aggressive cost targets, as tracked in our analysis of Starship launch cost estimates and external New Glenn launch cost evaluations. Because NASA relies on cost-plus contracts with legacy aerospace vendors, production overruns and delays increase the public bill rather than falling on private shareholders.

The Canceled Hardware

A major focus of Artemis program criticism centers on billions spent on equipment that NASA ultimately abandoned. In June 2026, the NASA OIG released interim memo ML-26-002, titled “NASA’s Management of Programs and Projects After Mission Termination: Artemis Campaign Systems.” The memo revealed that NASA spent approximately $5.9 billion on Artemis-related contracts and hardware that were canceled after an architecture restructuring in February and March 2026. Trade reporting from Space.com emphasized that this expensive hardware may never be used.

The single largest abandoned effort was Boeing’s work on the Exploration Upper Stage (EUS). The EUS was designed to replace the smaller Interim Cryogenic Propulsion Stage on the SLS, upgrading the launch vehicle from Block 1 to the heavier Block 1B configuration.

Initial contract value: $962 million
Value at stop-work order: nearly $2 billion
OIG completion estimate: $3.7 billion (roughly $750 million above Boeing’s own estimate)
First-delivery schedule slip: about 7.5 years late (to November 2028)

Boeing’s EUS contract was originally added to its existing SLS contract at an estimated value of $962 million. By the time NASA issued a formal stop-work order in March 2026, spending on the EUS had expanded to nearly $2 billion. In its program review, the NASA OIG projected that completing the stage would cost $3.7 billion based on Boeing’s historical delivery trends. That watchdog projection exceeded Boeing’s own internal completion estimate by roughly $750 million.

Delivery milestones slipped just as rapidly as costs escalated. The OIG found that delivery of the first flight-ready upper stage had drifted to November 2028. That revised delivery date sat roughly 7.5 years behind the agency’s initial baseline schedule. NASA officially described Boeing’s EUS contract performance as unsatisfactory.

What GAO Found About Orion’s Overruns

Contract delays on the Orion spacecraft have caused cascading budgetary pressures across NASA’s wider science and human spaceflight efforts. On July 23, 2026, the Government Accountability Office released Report GAO-26-108556, “NASA: Assessments of Major Projects.” The audit showed that the Orion crew capsule program alone generated more than half of the combined annual cost overruns across all major NASA projects.

Orion also accounted for nearly 75 percent of the cumulative cost overruns in the agency’s active major project portfolio. The capsule incurred an annual overrun of $261 million in that assessment cycle. The GAO tied this overrun directly to a seven-month schedule slip on the Artemis II mission. That mission, which flew the first crewed test flight around the Moon, slipped from a planned September 2025 launch date to an actual liftoff on April 1, 2026, before splashing down on April 10, 2026.

Those Orion increases harmed NASA’s overall major-project performance:

Cumulative cost growth across the 18 major NASA projects assessed in 2026 increased from $4.4 billion to nearly $4.7 billion.
Cumulative schedule delays across those same 18 major projects climbed from 13.1 years to 14 years.
Orion overruns absorbed capital that could have supported other deep space and planetary science missions.

The GAO’s findings provided concrete data for critics who argue that the Artemis program budget absorbs a disproportionate share of NASA funding. Because the Orion development operates under federal contract structures that reimburse allowable contractor costs, extended testing and schedule delays convert directly into additional public expenditures. Broader context on how this fits into federal space funding appears in our guide on the US space program.

How Artemis Compares to Apollo

Historic lunar exploration cost substantially more than Artemis has consumed to date. According to data compiled by The Planetary Society, the United States spent $25.8 billion on Project Apollo between 1960 and 1973. When adjusted for inflation to 2025 dollars, that historical commitment totals approximately $309 billion.

Project Apollo (1960 to 1973): roughly $309 billion inflation-adjusted ($25.8 billion nominal)
Apollo plus Gemini and robotic lunar precursors: roughly $338 billion inflation-adjusted ($28.0 billion nominal)
Artemis program (FY2012 to FY2025 projection): roughly $93 billion nominal

If precursor initiatives are included, Apollo’s fiscal footprint expands further. Adding Project Gemini and early robotic lunar probe programs brings Apollo-era nominal spending to $28 billion. That combined lunar effort equates to roughly $338 billion in 2025 inflation-adjusted dollars. Inflation adjustments depend heavily on whether analysts apply the general Consumer Price Index (CPI) or specialized federal indices like NASA’s New Start Index. As a result, the $309 billion to $338 billion range provides an approximate benchmark rather than an exact accounting total.

Even with substantial cost growth, Artemis spent about $93 billion through fiscal year 2025. That means the modern lunar campaign cost less than one-third of the inflation-adjusted financial commitment made during the 1960s. However, Apollo developed new launch vehicles, lunar modules, flight software, and navigation systems from scratch within a single decade. Artemis relied heavily on legacy Space Shuttle components, leading oversight watchdogs to scrutinize why modernization took over 14 years to produce its first crewed mission.

The Lander Contracts in Context

Human landing systems account for a smaller share of overall Artemis program cost overruns than expendable flight hardware. NASA structured its commercial lunar lander procurements as firm-fixed-price contracts, requiring commercial partners to absorb development overruns beyond their initial contract awards.

A NASA OIG review published on March 10, 2026, tracked cost growth and schedule performance across both Human Landing System (HLS) awards:

SpaceX Starship HLS: Awarded in April 2021 at $2.89 billion, the contract saw total costs grow by about 6 percent by March 2026.
Blue Origin Blue Moon HLS: Awarded in May 2023 at $3.4 billion, the contract saw total costs grow by less than 1 percent by March 2026.

While both commercial lander systems faced technical delays and crew-safety-risk findings highlighted by the inspector general, their contract values grew far less than the Orion capsule or the Exploration Upper Stage. Fixed-price contracting shielded NASA from major lander cost overruns, isolating the bulk of the program’s budget inflation to government-owned launch systems and capsules.

What Changes the Artemis Program Cost Picture

The cost picture for the Artemis program will depend on how NASA addresses expendable hardware costs and future contract restructurings:

OIG and GAO Reporting Cycles: Watchdog audits covering fiscal year 2026 and beyond will establish whether the agency can rein in post-Artemis II Orion capsule spending.
Commercial Lander Milestones: Flight testing for the SpaceX and Blue Origin lunar landers will determine whether fixed-price contracts stay near their baseline awards.
Architecture Restructuring Impacts: NASA must demonstrate whether terminating troubled contracts like Boeing’s EUS saves public capital or simply creates new integration expenses.
