The 2027 test that will decide Artemis III’s fate
When NASA officials confirmed this week that both SpaceX and Blue Origin had committed to a late-2027 rendezvous and docking test, they described it as a critical step toward validating the mission’s architecture. However, the scope of that test remains under discussion. The agency is evaluating whether to include a crewed flight of the lander itself, though current plans suggest a more limited demonstration—one that may not replicate the full Earth-orbit shakedown performed during Apollo, when astronauts separated the lunar module from the command module for independent operations.
The complexity of this mission extends beyond past efforts. Starship and Blue Moon are designed to be reusable, requiring in-space refueling to transport crews and cargo between lunar orbit and the surface. Officials have emphasized that the 2027 test is not merely about proving a single landing but about validating the broader system: a late-2027 rendezvous, docking, and assessment of interoperability between the landers and NASA’s Orion spacecraft. This approach reflects the agency’s strategy of treating the two landers as part of a redundant, privately developed architecture essential to its long-term lunar ambitions.
What remains unclear is the readiness of key subsystems. SpaceX’s Starship has yet to complete an orbital flight without incident, let alone demonstrate the ability to sustain a crew for extended periods. Blue Origin’s Blue Moon lander, meanwhile, continues testing its BE-7 engine, which must precisely throttle to land a heavy vehicle on the Moon’s uneven terrain. Neither company has provided comprehensive updates on the status of life-support systems, human-rated engines, or docking mechanisms, leaving progress to be inferred from test firings and public statements.
Why this Moon landing is harder than Apollo
While Artemis III’s delay may resemble past schedule slips, the technical challenges differ significantly from those of the Apollo era. Apollo’s lunar module was a single-use vehicle designed for a brief surface stay. In contrast, Starship and Blue Moon are intended to be refueled in space and reused, enabling not just a single landing but a sustained lunar presence.
This reusability introduces new layers of complexity. Apollo’s life-support system was designed for a 65-hour mission. Starship’s must function for weeks, while also docking with Orion in lunar orbit. Blue Moon faces similar hurdles, including a docking mechanism compatible with both Orion and the planned lunar Gateway station. Neither company has publicly demonstrated these systems in a space-like environment, raising questions about their readiness.
- Apollo lunar module (1969): 4.3 meters tall, 15 metric tons, single-use, no refueling, 65-hour life support.
- SpaceX Starship (2027 target): 50 meters tall, 100+ metric tons, reusable, requires orbital refueling, multi-week life support.
- Blue Origin Blue Moon (2027 target): 16 meters tall, 16 metric tons, reusable, requires orbital refueling, multi-week life support.
The refueling requirement alone presents risks Apollo never encountered. Starship will need to transfer cryogenic propellants between tankers in Earth orbit before departing for the Moon—a process that has never been attempted with humans on board. Blue Origin’s lander relies on a similar refueling scheme, though details about its progress remain limited. Officials have noted that this capability is essential not just for returning to the Moon but for establishing a lunar base and delivering large payloads affordably.

How NASA will verify these systems before crewed missions remains an open question. The agency’s plan includes an uncrewed Blue Moon cargo landing near the lunar south pole before the 2027 test, though that mission has yet to be scheduled. SpaceX, meanwhile, must still demonstrate Starship’s ability to survive reentry and dock with another vehicle in orbit—critical milestones that have yet to be achieved.
The taxpayer’s bet on commercial landers
NASA’s decision to award fixed-price contracts to SpaceX and Blue Origin marked a shift toward leveraging commercial innovation. The agency’s Human Landing System (HLS) program was structured to encourage private investment, with the expectation that both companies would contribute significant resources beyond the government’s funding. Officials have acknowledged that the companies are investing substantially in these capabilities, though the exact amounts remain undisclosed.
This model assumes that commercial partners can deliver on schedule, a premise already tested by delays. SpaceX’s Starship development has faced setbacks, including high-profile test failures, while Blue Origin’s Blue Moon lander has yet to fly. The fixed-price contracts place financial risk on the companies, limiting NASA’s ability to intervene if development stalls. Unlike Apollo, where the agency oversaw every component, Artemis relies on contractors to manage progress internally and report issues as they arise.
The approach has produced mixed outcomes. SpaceX’s iterative development has yielded advances like the Raptor engine but has also led to setbacks, such as a 2023 launchpad incident that destroyed a prototype. Blue Origin has taken a more deliberate path, though its BE-7 engine has encountered its own delays. Neither company has provided detailed updates on life-support or docking systems, leaving stakeholders to rely on public statements and test results.
The broader financial context adds another layer of complexity. NASA’s fiscal 2027 budget proposal seeks a meaningful share of the agency’s overall funding, though the final amount remains under review. While the proposal does not directly target Artemis, any reductions could pressure the program if the 2027 test reveals significant technical hurdles. For now, the agency has prioritized maintaining funding for the landers, though future adjustments may depend on their performance.
What’s next: The 2027 test and the 2028 landing attempt
The late-2027 rendezvous and docking test represents a pivotal moment for Artemis III. If successful, it could pave the way for a 2028 landing attempt, though that timeline assumes no further delays. If the test encounters issues, NASA may need to reconsider its reliance on commercial landers or adjust the mission’s scope.
This follows our earlier report, Artemis II: NASA Crew Faces Communications Blackout Behind the Moon.
The 2027 test will serve as more than a technical demonstration. It will assess NASA’s ability to integrate private-sector innovation with its safety standards and force the agency to confront the trade-offs of a Moon program that is both more ambitious and more dependent on unproven technology than Apollo. The outcome will shape not just the timeline for returning humans to the Moon but also the approach to deep-space exploration for years to come.
For now, the focus remains on foundational questions: Can Starship and Blue Moon dock with Orion? Can their life-support systems sustain crews for extended missions? Can they be refueled in space? The answers will determine whether the Artemis program can achieve its goals or face further setbacks.
In the meantime, external assessments are already weighing the likelihood of success. One prediction market assigns a higher probability to Blue Origin landing an uncrewed Blue Moon on the Moon before SpaceX achieves a similar milestone with Starship, though these projections could shift if SpaceX completes its next major objective: a successful orbital flight of Starship Version 3, targeted for 2026.
What to watch in 2027
- Starship Version 3’s orbital flight (2026): SpaceX’s next-generation rocket must demonstrate it can reach orbit, reenter, and land intact. A failure here could delay the 2027 test.
- Blue Origin’s uncrewed Blue Moon cargo landing (2026-2027): A successful landing near the lunar south pole would validate Blue Moon’s guidance and propulsion systems, though the mission has yet to be formally scheduled.
- The late-2027 rendezvous and docking test: This will be the first time Orion, Starship, and/or Blue Moon attempt to operate together in space. A smooth test would build confidence for 2028; complications could force NASA to rethink its lander strategy.
The delay to late 2027 is not merely a schedule adjustment—it reflects the Artemis program’s effort to forge a new path to the Moon, one that depends on commercial partnerships, reusable hardware, and in-space refueling. Whether this approach leads to a sustainable lunar presence or faces further challenges will depend on how SpaceX, Blue Origin, and NASA navigate the obstacles ahead.
