NASA is revising its moon-landing plans, reducing Boeing's role while elevating SpaceX's Starship rocket to do the job of propelling astronauts to lunar orbit, according to reporting first published by Bloomberg and confirmed through multiple sources.
The proposal marks a striking departure from decades of Artemis architecture. The plan would see Orion launch to Low Earth Orbit aboard the Space Launch System (SLS), rendezvous with Starship, and have SpaceX's vehicle carry the crew the rest of the way to the Moon, beginning after Artemis V. A Starship lander would meet up and dock with the capsule around the moon, before taking astronauts down to the lunar surface.
The logic appears sound from an efficiency standpoint. By having Orion reach Low Earth Orbit on a smaller launch vehicle and rendezvous with Starship, NASA could bypass the need for the massive and expensive SLS for later missions. The hitch: the plan requires congressional approval, technical demonstrations that have yet to occur, and represents a frank acknowledgement that current strategy isn't working.
A Shifting Landscape Under New Leadership
New NASA administrator Jared Isaacman, a former SpaceX customer, reshuffled the schedule shortly after taking office. Artemis III is now a 2027 Low Earth Orbit mission to test lunar landing technology, with an actual landing pushed to Artemis IV in 2028 and Artemis V potentially following the same year.
Isaacman's broader restructuring reflects hard-nosed pragmatism. Jumping from a flight around the moon with Artemis II to a landing mission in Artemis III is "too big of a gap," particularly when the Space Launch System rocket and Orion spacecraft only launch once every three or more years. Launching a rocket every three years is not a path to success; when you are launching every three years, your skills atrophy, you lose muscle memory, Isaacman observed.
This directly addresses a genuine problem. The SLS has long been central to NASA's Artemis architecture, yet its future has grown increasingly uncertain. A budget proposal from the current administration suggested cancelling it after Artemis III, before that was walked back.
The Technical and Financial Reality
The SLS remains a study in institutional inertia. The SLS, irrespective of its faults, has actually flown, completing one uncrewed mission. Yet delays and budget overruns have become routine. Leaking hydrogen at the base of the Space Launch System rocket, uncovered during a key fueling test, forced NASA to forgo all available launch opportunities in March. Similar issues have plagued both Artemis I and II, suggesting fundamental design or integration problems that three-year gaps between missions are unlikely to solve.
The real question is practical: can Starship do the job? Starship's next test flight is scheduled for April; if it succeeds, 2026 could finally be the year the vehicle demonstrates orbital capacity, leaving two years to ready it for a lunar role by 2028. That timeline is ambitious but not impossible if development accelerates.
Critically, the SLS is the only rocket that can send Orion, astronauts, and cargo directly to the Moon in a single launch, according to NASA's official position. But necessity often drives change in engineering. A rendezvous strategy eliminates that single-launch requirement and opens options.
Who Wins and Who Loses
Boeing has obvious reasons to worry. Under the original plan, Boeing's Space Launch System rocket would have sent a crew of four riding inside the Lockheed Martin-built Orion crew capsule to the moon. SLS represents billions in revenue. Yet Boeing has publicly remained supportive of whatever NASA requires, with company officials stressing their commitment to accelerated timelines.
SpaceX stands to gain substantially if Starship becomes the standard lunar ferry. The company already holds a 4.4 billion dollar contract with NASA to develop Starship as the Human Landing System (HLS) for the Artemis III mission. Expanding Starship's role would cement its position as NASA's primary commercial partner for deep space.
Blue Origin, developing the Blue Moon lander, remains positioned for that specific role, but a Starship monopoly on lunar orbit transport would narrow its opportunities.
The Unresolved Challenges
Congressional support is far from certain. The SLS programme sustains jobs across multiple states and districts. Isaacman said he had similar conversations with all our stakeholders in Congress, and they're fully behind NASA in this approach. But public support for a major programme shift doesn't always survive budget scrutiny or reelection cycles.
Technical hurdles are equally real. The Orion spacecraft will serve as the exploration vehicle that will carry and sustain the crew on Artemis missions to the Moon and return them safely to Earth. But Starship, as currently designed, lacks a proven crew escape system and hasn't demonstrated re-entry at lunar return velocities. Orion remains essential precisely because Starship cannot do everything.
NASA's path back to the Moon remains anything but settled. What this proposal demonstrates is that the agency's leadership recognises the old path isn't working. Whether a new one holds up to scrutiny, bureaucracy, and political pressure is another matter entirely.
