The next time NASA astronauts climb aboard an Orion capsule, they will not be heading for the lunar surface. The agency announced in May 2025 that it has redesigned Artemis III as an orbital shakedown cruise, stripping the crewed Moon landing from the mission and replacing it with a rendezvous-and-docking exercise in low-Earth orbit. The flight is now targeted for late 2027, and the earliest any astronaut could set foot on the Moon has slipped to 2028 at the soonest, under a newly added Artemis IV mission. The reason is straightforward: neither SpaceX’s Starship lunar lander nor Blue Origin’s Blue Moon vehicle is ready, and NASA has run out of room to pretend otherwise.
What NASA actually changed
Under the revised plan, Artemis III will send a crew in Orion to dock with one or both commercial landers in low-Earth orbit, testing the interfaces and procedures that a lunar mission would demand. NASA has described this as a necessary integration step before attempting a crewed descent. Crew assignments and detailed mission parameters have not been announced; the agency says those will come closer to launch.
The restructuring did not come as a surprise to federal auditors. A Government Accountability Office report (GAO-24-106256), published before NASA’s announcement, concluded that a crewed lunar landing on the original 2025 timeline was unlikely. The GAO pointed to delays in both the Human Landing System contracts and the development of new lunar spacesuits, noting that schedule pressure had been building for years. NASA’s Office of Inspector General separately audited the agency’s management of the HLS contracts, reinforcing concerns about oversight of the two commercial partners.
Blue Origin holds a contract under NASA’s NextSTEP-2 Appendix P track, a procurement line originally scoped for sustaining lunar missions beyond the first landing. SpaceX’s Starship HLS contract, awarded earlier under a separate selection, covers the initial landing capability. Both vehicles now need to prove themselves during the orbital test before NASA will commit either to carrying astronauts to the Moon.
Where the landers actually stand
SpaceX has conducted multiple Starship test flights from its Boca Chica, Texas facility, achieving orbit and demonstrating booster recovery techniques. But the gap between an orbital test vehicle and a crew-rated lunar lander is enormous. The Starship HLS variant requires a life-support system, a lunar-capable propulsion configuration for descent and ascent, crew-rated docking hardware compatible with Orion, and the ability to store cryogenic propellant in space long enough to complete a mission. None of these capabilities have been publicly demonstrated on a fixed timeline.
Blue Moon has received far less public attention. Most available information comes from procurement documents rather than engineering updates, and Blue Origin has not released a detailed development schedule. The company’s New Glenn rocket, which would support Blue Moon operations, completed its first orbital flight in 2025, but the lander itself remains in earlier stages of development.
The spacesuit situation adds another layer of complexity. NASA contracted Axiom Space to build the next-generation lunar EVA suits, and that program has faced its own timeline challenges. The GAO flagged suit readiness as a risk factor alongside the landers, and a lunar landing cannot happen without them regardless of how quickly the vehicles mature.
Artemis II and the domino effect
Artemis III’s schedule also depends on Artemis II, the crewed Orion flight around the Moon that must fly first. As of mid-2026, Artemis II has not launched. Any further delays to that mission would cascade directly into the Artemis III timeline, compressing the window for the orbital test or pushing it past late 2027. NASA has not publicly addressed contingency planning if Artemis II slips further.
The broader Artemis architecture now includes the Gateway lunar space station, which factors into missions beyond Artemis IV. But Gateway’s own assembly schedule depends on commercial launch availability and international partner contributions, adding yet another variable to a program already defined by interdependent timelines.
The budget and political backdrop
NASA has not disclosed updated cost figures tied to the revised Artemis III scope. The GAO identified cost risk alongside schedule risk in its assessment, but specific dollar amounts for the restructured mission have not appeared in any official release. Congressional appropriations for Artemis have faced scrutiny in recent budget cycles, and the program’s political support depends in part on visible progress. Converting Artemis III into an orbital test keeps the mission cadence alive and gives lawmakers something to point to, even if the Moon landing itself remains years away.
The decision also reflects a practical calculation about contractor accountability. By setting a late 2027 deadline for at least partial vehicle readiness, NASA creates a forcing function for both SpaceX and Blue Origin. If only one lander is ready by then, the agency has not said how it would choose between them for the orbital exercise, or what consequences the other contractor might face.
Why the 2028 landing target deserves skepticism
NASA originally planned Artemis III itself as the landing mission, and federal auditors flagged that timeline as unrealistic years before the agency acknowledged it. The same dynamic could easily repeat with the 2028 target for Artemis IV. Achieving a crewed lunar descent just one year after an orbital integration test would require both landers to clear their remaining milestones at a pace neither company has demonstrated. It would also require the spacesuit program to deliver flight-ready hardware on a parallel track.
The restructured approach does carry one genuine advantage: building in an explicit rehearsal step means problems can surface during the orbital test rather than during a lunar descent. That buffer could prevent the kind of cascading failures that have historically plagued ambitious spaceflight programs. Whether it is sufficient depends entirely on how quickly SpaceX and Blue Origin close the gap between where their vehicles are now and what a Moon mission demands.
For anyone who remembers the original Artemis timeline, which promised American boots on the Moon by 2024, the pattern is familiar. Dates shift, architectures evolve, and the Moon stays patient. The difference this time is that NASA has two commercial partners shouldering much of the technical risk, and neither has yet proven it can deliver a vehicle capable of landing humans on another world. The orbital test in 2027, if it happens on schedule, will be the first real measure of whether this generation’s lunar ambitions are on firmer ground than the timelines that preceded them.
