TL;DR
NASA's Artemis III mission, the first crewed lunar landing since Apollo 17, will now launch no earlier than late 2027. Both SpaceX and Blue Origin have informed NASA that their respective Human Landing Systems (HLS) will be ready for that timeframe, pushing the timeline back by at least two years from prior public targets.
What Happened
On Tuesday, April 28, 2026, Ars Technica reported that NASA's Artemis III mission — the cornerstone of the agency's return-to-the-Moon program — will launch no earlier than late 2027. The delay stems directly from separate notifications by SpaceX and Blue Origin to NASA that their lunar landers, the Starship HLS and Blue Moon Mark 2 respectively, will not be ready for flight until that revised window.
Key Facts
- NASA's Artemis III mission, originally targeting a 2025 launch, is now slated for no earlier than late 2027 — a slippage of at least two years from previous public schedules.
- SpaceX is developing the Starship Human Landing System (HLS) under a $2.9 billion contract awarded in April 2021.
- Blue Origin is building the Blue Moon Mark 2 lander under a $3.4 billion contract awarded in May 2023 as a second-source landing capability.
- Both companies independently informed NASA that their landers would achieve operational readiness for Artemis III in the late 2027 timeframe.
- The Artemis III mission calls for the first crewed lunar landing since Apollo 17 in December 1972 — a gap of 55 years.
- The Space Launch System (SLS) rocket and Orion crew capsule, which launch the astronauts, remain on track for an uncrewed Artemis I (completed November 2022) and a crewed Artemis II (currently targeting late 2025).
- Congress has appropriated over $93 billion for the Artemis program through Fiscal Year 2026, with annual spending exceeding $7 billion.
Breaking It Down
The simultaneous delay from both SpaceX and Blue Origin is not a coincidence — it reflects the fundamental engineering challenge of developing a human-rated lunar lander from scratch. SpaceX's Starship HLS requires an orbital refueling capability that has never been demonstrated at scale: the vehicle must transfer hundreds of metric tons of propellant between tanker Starships in low Earth orbit before it can depart for the Moon. Blue Origin's Blue Moon Mark 2, while using a more conventional architecture, depends on the BE-7 engine, which has yet to complete a full-duration flight qualification test campaign.
$6.3 billion — the combined value of the SpaceX and Blue Origin lander contracts — has been committed to two landers that will both be delivered in the same 12-month window, late 2027, after years of schedule slips.
This dual-track strategy was intended to create redundancy and competition. Instead, both tracks have converged on the same delayed timeline, exposing a deeper truth: the Artemis program's critical path runs through unproven, high-risk technologies. NASA's own Government Accountability Office (GAO) warned in a 2023 report that Starship HLS faced "high schedule risk" due to the number of new technologies required. Blue Origin's lander, though less technically audacious, has suffered from its own development delays, including a 2023 lawsuit against NASA over the original single-source contract award to SpaceX.
The late-2027 date also forces NASA to confront a difficult budgetary reality. The $93 billion already spent on Artemis has not yet produced a single crewed lunar landing. Each year of delay adds approximately $7 billion in program costs, meaning the total tab before Artemis III flies could approach $110 billion. That figure does not include the cost of sustaining the Gateway lunar orbital outpost, the Artemis Base Camp surface infrastructure, or the lunar terrain vehicle contracts.
What Comes Next
The immediate consequence of this delay is a reshuffling of NASA's entire lunar campaign timeline. Artemis II, the first crewed flight of Orion around the Moon, remains scheduled for late 2025, but that date is itself under pressure from heat shield issues discovered during Artemis I. Artemis III, now in late 2027, will be followed by Artemis IV, the first docking with Gateway, likely slipping into the 2030s.
- SpaceX orbital refueling demonstration: The single most critical technical milestone for Starship HLS is a propellant transfer test between two Starship vehicles in orbit. This has never been attempted. Watch for a mid-2027 target date for this test — any failure here could push Artemis III into 2028 or beyond.
- Blue Origin BE-7 qualification: Blue Origin must complete a full-duration, full-throttle test campaign of the BE-7 engine, including multiple restarts in a vacuum chamber. The 2026–2027 timeframe is critical; a failure would leave NASA with only SpaceX as a lander provider.
- Artemis II heat shield resolution: NASA must certify the Orion heat shield after the Artemis I mission revealed unexpected charring and material loss. A decision is expected by late 2026; if the fix requires a redesign, Artemis II could slip into 2026, pushing Artemis III into 2028.
- Congressional budget response: The $7+ billion annual Artemis budget faces increasing scrutiny from both parties. The late-2027 date gives lawmakers a concrete target for potential funding cuts or reallocations in the FY2027 appropriations cycle.
The Bigger Picture
This delay underscores two broader trends reshaping human spaceflight. First, Commercial Lunar Lander Dependence: NASA has bet its entire crewed lunar return on two private companies — SpaceX and Blue Origin — neither of which has ever landed a human on the Moon. This is a radical departure from the Apollo era, where NASA owned and operated all hardware. The trade-off is lower upfront cost but higher schedule risk, as the agency cannot directly control its contractors' development pace.
Second, The Infrastructure Gap: Unlike Apollo, which used a single, integrated Saturn V–Apollo stack, Artemis requires a sprawling architecture: SLS, Orion, Gateway, two different landers, orbital refueling, and surface systems. Each element adds a failure point and a schedule dependency. The late-2027 date is not a single problem but a cascading effect of multiple unproven technologies. This complexity is the price of a sustainable, rather than flags-and-footprints, approach to lunar exploration — but it also means the first crewed landing may not occur until nearly 60 years after the last one.
Key Takeaways
- Schedule Slip: Artemis III will launch no earlier than late 2027, a two-year delay from prior targets, driven by lander readiness from both SpaceX and Blue Origin.
- Dual-Track Risk: Both $2.9 billion (SpaceX) and $3.4 billion (Blue Origin) lander contracts have converged on the same delayed timeline, eliminating the redundancy NASA hoped to achieve.
- Cost Escalation: With annual Artemis spending exceeding $7 billion, the total program cost before the first crewed landing could approach $110 billion, raising political vulnerability.
- Technical Hurdles: Orbital refueling for Starship and BE-7 engine qualification for Blue Moon remain unproven; failure in either could push Artemis III into 2028 or beyond.
