NASA’s Artemis II mission, targeting liftoff no earlier than April 1, 2026, represents the first crewed flight of the Space Launch System and Orion spacecraft around the Moon. But the mission carries weight far beyond its trajectory. For legacy aerospace contractors responsible for building and integrating the rocket, Artemis II has become a high-stakes proving ground at the very moment when commercial rivals SpaceX and Blue Origin are winning larger roles in the lunar program. The question is no longer whether these newer entrants will participate in Artemis, but whether the established industrial base can justify its cost structure as competition tightens.
SLS Assembly Nears Completion at Kennedy Space Center
Inside the Vehicle Assembly Building at Kennedy Space Center, the physical rocket is coming together. NASA confirmed that the upper stage was integrated as teams continued stacking the SLS for Artemis II. All four RS-25 engines have been installed and secured onto the core stage, with engineers applying lessons learned from Artemis I to the production and assembly process.
The rocket’s configuration tells its own story about continuity. Artemis II’s SLS includes a core stage, four RS-25 engines, two five-segment solid rocket boosters, an interim cryogenic propulsion stage, adapters, and an Orion stage adapter. According to NASA, major sections remain unchanged from the Artemis I vehicle. That design stability benefits the same contractors who built the first rocket, primarily Boeing for the core stage and Northrop Grumman for the solid rocket boosters. But it also means the cost and schedule problems that plagued Artemis I have not been structurally redesigned away. They have simply been carried forward with incremental fixes.
For NASA, the near-term priority is to finish integration and roll the stacked vehicle out to the pad for a full-up rehearsal ahead of launch. For the industrial base, however, Artemis II is a test of whether the program can transition from a one-off demonstration to something resembling a production line. If the second SLS can be assembled more efficiently, with fewer rework cycles and schedule slips, it will strengthen the argument that the rocket can support a sustainable cadence of lunar missions.
Watchdog Reports Expose Cost and Schedule Gaps
Federal oversight agencies have repeatedly flagged the financial trajectory of SLS-era contracts. A GAO report focused on SLS affordability found that NASA lacked adequate cost transparency and had not properly baselined production costs beyond Artemis I. Without that discipline, the report warned, the agency cannot reliably monitor whether the program is becoming more or less affordable over time. That finding matters because SLS is not a one-off rocket; NASA needs it to fly repeatedly for the Artemis campaign to succeed.
A separate NASA Office of Inspector General audit examined the agency’s management practices for major SLS contracts, including those for the core stage, upper stage, RS-25 engines, and solid rocket boosters, against cost, schedule, and performance goals. The audit documented structural shortfalls in how these contracts were overseen, noting that optimistic planning assumptions and contract modifications contributed to billions of dollars in cost growth and years of delay.
The GAO’s annual assessment of NASA’s major projects also captured portfolio-wide overruns, including Orion’s share of cumulative baseline cost growth across the Artemis program. When taken together, these findings paint a picture of a flagship exploration effort that has struggled to control expenses across multiple, interdependent elements. Artemis II will fly on hardware shaped by those earlier decisions, and its performance will influence whether Congress and NASA leadership continue to tolerate existing cost trends.
Ground infrastructure adds another layer of financial risk. An oversight report on mobile launchers examined both the modifications to ML-1 and the planning and risks associated with ML-2. These ground systems are often invisible in public discussions of Artemis, but they are part of the same legacy contractor ecosystem, and their cost growth constrains the cadence at which NASA can fly missions. If mobile launch infrastructure cannot be readied in time or within budget, even a fully assembled SLS and Orion could face extended delays on the ground.
Blue Origin and SpaceX Reshape the Competitive Field
While legacy contractors work to hold their position, NASA has been deliberately expanding the number of commercial players in the Artemis architecture. The agency selected Blue Origin as the second Human Landing System provider for Artemis V, creating a dual-source approach for lunar landers. That decision was explicitly designed to provide multiple providers and competition for landing astronauts on the Moon, reflecting lessons learned from commercial cargo and crew programs in low Earth orbit.
The path to that selection was not smooth. After NASA initially chose only SpaceX for the first HLS contract under Option A, both Blue Origin and Dynetics filed bid protests. The GAO resolved those challenges in a formal protest decision, establishing a detailed chronology of non-selection notices, debriefing materials, and the review standard applied. The protests failed, but they intensified political and industry pressure on NASA to broaden participation in the lander program, ultimately contributing to the agency’s move to fund a second provider.
This dual-lander strategy creates a dynamic that did not exist during the early Shuttle or even early SLS era. SpaceX and Blue Origin are developing their landers under fixed-price or milestone-based structures that shift financial risk away from the government. That stands in sharp contrast to the cost-plus contracts that define most SLS and Orion work. For taxpayers, the difference is direct: cost-plus contracts reimburse contractors for expenses and add a fee on top, meaning overruns are largely absorbed by the government. Fixed-price contracts force the contractor to manage costs or absorb losses if development runs late or over budget.
As these commercial systems mature, NASA will gain more data on how much lunar transportation truly costs when industry is exposed to more risk. If landers developed under fixed-price arrangements can deliver comparable or better performance at lower total cost, pressure will grow to reassess how much the agency spends on each SLS launch and on the associated Orion spacecraft. Artemis II, as the first crewed SLS mission, is therefore not just a technical milestone but a benchmark against which future commercial alternatives will be judged.
The COMET Contract and the Road to 2033
NASA’s contracting decisions for ground operations also reveal how the agency is thinking about the next decade. The COMET contract, a cost-plus incentive and award-fee indefinite-delivery, indefinite-quantity agreement for launch processing and ground support at Kennedy Space Center, extends the same legacy contracting model that governs much of SLS and Orion. Under COMET, the contractor is reimbursed for allowable costs and can earn additional fees for meeting performance targets, but the government still shoulders most of the financial risk if work takes longer or proves more complex than anticipated.
Within this framework, NASA has outlined an operational roadmap that extends well beyond Artemis II. Agency planning documents describe a notional manifest of crewed and cargo missions into the early 2030s, including Artemis flights that would assemble and supply a small lunar-orbiting platform and deliver surface infrastructure to the Moon. To support this vision, COMET is structured to cover multiple SLS launches, Orion processing flows, and integration of payloads such as landers and logistics modules.
The contract’s timeline and scope implicitly assume that SLS will remain the backbone of NASA’s deep-space transportation architecture through at least 2033. That assumption runs headlong into the affordability concerns raised by oversight bodies. If each SLS launch continues to cost several billion dollars when all supporting infrastructure is included, the total number of missions the agency can afford may be far smaller than the manifest suggests. In that scenario, the commercial landers being developed by SpaceX and Blue Origin could find themselves waiting for rides that are too infrequent to sustain a vibrant lunar economy.
Conversely, if NASA can use COMET and related contracts to gradually introduce more performance-based incentives, streamline ground operations, and reduce turnaround times between launches, it could lower per-mission costs even without fundamentally changing the SLS design. That would give the legacy industrial base a stronger argument that it can adapt to a more competitive, budget-constrained environment.
For now, Artemis II sits at the intersection of these competing forces. The rocket being stacked in the Vehicle Assembly Building reflects a decade of investment in traditional, cost-plus development. The landers it will eventually rendezvous with in lunar orbit are being built under newer, more commercially oriented models. The ground systems that will send it to space are locked into long-term support contracts that blend old and new incentive structures.
How Artemis II performs (technically, financially, and operationally) will shape not only the trajectory of the Artemis program but also the future balance between legacy contractors and their commercial rivals. If the mission demonstrates that SLS and Orion can fly safely and more efficiently the second time around, it will bolster arguments for maintaining a government-owned heavy lifter as the centerpiece of lunar exploration. If instead it highlights persistent cost growth and schedule strain, the case for shifting more responsibility to fixed-price, commercially led systems will only grow stronger.
