NASA has confirmed a revised lunar transportation architecture that would use four New Glenn launches to deliver Blue Origin’s Blue Moon Mark 2 crewed lander and its supporting propulsion stages into Earth orbit.
The configuration replaces Blue Origin’s earlier plan to rely on orbital propellant transfers between spacecraft during its initial crewed lunar landing campaign.
Under the revised approach, three propulsion stages will be launched separately, followed by the Blue Moon Mark 2 Alpha lander.
The spacecraft will assemble in Earth orbit before traveling toward the Moon.
NASA announced the updated architecture on October 23, 2026, as part of its revised commercial lunar lander development plans.
The agency is targeting a crewed lunar landing in 2028 and will select between Blue Origin and SpaceX based on lander readiness.
Four New Glenn Launches Instead of Orbital Refueling
Blue Origin’s original Human Landing System architecture incorporated propellant-transfer operations involving separately launched spacecraft.
The revised architecture defers those transfers for the initial crewed lunar landing missions.
Instead, Blue Origin plans to launch three propulsion stages derived from its existing Blue Moon Mark 1 and Mark 2 hardware.
Each transfer stage will carry its own propulsion system and propellant supply.
A fourth New Glenn launch will deliver the Blue Moon Mark 2 crewed lander.
The four spacecraft elements will rendezvous and dock in low Earth orbit, forming a combined vehicle for the journey toward the Moon.
NASA describes the propulsion stages as operating in a manner similar to a multistage rocket.
The assembled spacecraft will depart Earth orbit and travel toward an elliptical polar orbit around the Moon.
As the propellant in each transfer stage is depleted, that stage will separate from the remaining spacecraft.
The next stage will then provide propulsion for the continuing journey.
This arrangement avoids the need to transfer cryogenic propellant from one spacecraft into another during the initial mission.
The four-launch architecture was also detailed in Ars Technica’s October 23 reporting, which identified the New Glenn launch requirements associated with the revised plan.
How the Transfer Stages Will Function
The transfer stages are based on propulsion technologies and spacecraft hardware being developed for Blue Origin’s lunar lander program.
Blue Moon uses liquid hydrogen and liquid oxygen propulsion.
These propellants provide high efficiency for the substantial velocity changes required during lunar transportation.
Under the new arrangement, the stages operate as individual propulsion modules connected to the lander.
The initial stages provide propulsion for departure from Earth orbit and the journey toward the Moon.
Later propulsion operations place the remaining spacecraft into the planned lunar orbit.
Each stage carries a portion of the total propellant required for the mission.
By separating depleted stages, the spacecraft reduces the mass it must continue accelerating.
This is a conventional principle of multistage rocket design applied to a spacecraft assembly operating beyond Earth orbit.
The approach changes the balance between orbital launch operations and propellant-transfer technology.
Blue Origin must conduct multiple New Glenn launches and assemble the propulsion stack, but the initial crewed landing architecture will not require the orbital transfer of cryogenic propellant between the assembled vehicles.
NASA has not identified a final operational New Glenn configuration for every launch in the campaign.
Blue Moon Mark 2 Will Operate in Lunar Polar Orbit
NASA’s revised mission plan also changes the planned rendezvous location for Orion and Blue Moon.
The earlier Artemis architecture used a near-rectilinear halo orbit around the Moon.
The updated Blue Origin design targets an elliptical polar orbit, with NASA also examining opportunities for operations in lower lunar orbits.
The change reduces the distance and propulsion requirements associated with traveling between Orion and the lunar surface.
A lower rendezvous orbit allows the lander to perform a shorter ascent after completing lunar surface operations.
It can also provide more frequent opportunities for the astronauts to leave the lunar surface and return to Orion.
The Blue Moon lunar lander program includes both robotic and crewed spacecraft.
Mark 1 is the smaller robotic lander, intended to deliver payloads to the Moon and demonstrate technologies relevant to later missions.
Mark 2 is the crew-capable version intended to support NASA astronauts.
For the revised crewed landing mission, Orion will independently transport four astronauts from Earth toward the Moon.
Orion will rendezvous and dock with Blue Moon Mark 2 in lunar orbit.
Two astronauts will transfer into the lander, descend to the lunar south polar region, and conduct surface operations.
After completing their activities, they will return to lunar orbit aboard Blue Moon, dock with Orion, and transfer back to the crew spacecraft for the journey to Earth.
New Glenn’s Role in the Artemis III Demonstration
New Glenn is also expected to support the preceding Artemis III demonstration in 2027.
That mission will involve an Orion docking demonstration with a test version of Blue Moon Mark 2 in low Earth orbit.
According to NASA’s October 23 mission description, Blue Origin will launch its test lander into an orbit approximately 273 miles above Earth.
The spacecraft will be capable of remaining in orbit for up to 30 days, allowing scheduling flexibility for the subsequent Orion launch.
NASA will then launch the Artemis III crew aboard Orion using the Space Launch System.
After the spacecraft rendezvous and dock, astronauts will enter the Blue Moon test article and evaluate its cabin and supporting systems.
The planned docking campaign includes approximately two days of crew operations.
NASA will assess communications, flight control, environmental systems, pressure management, and the interaction between Orion and Blue Moon.
This demonstration is separate from the four-launch architecture planned for a later lunar landing mission.
Additional Blue Origin Development Requirements
NASA has updated its contracts with Blue Origin to include additional development milestones.
These include human-in-the-loop testing, meaning evaluations involving people interacting with spacecraft equipment and operational systems.
The agency has also introduced hardware readiness milestones intended to support astronaut training, ground processing, and flight operations.
Blue Origin must conduct an uncrewed demonstration of the mission profile before NASA certifies the lander for a crewed lunar landing.
The company plans to incorporate experience from its earlier Blue Moon Mark 1 robotic missions into its subsequent lander development.
NASA’s updated agreements no longer reserve a particular Artemis lunar landing for Blue Origin.
The original contract assigned Blue Moon Mark 2 to Artemis V. Under the revised approach, Blue Origin is eligible for the first crewed landing opportunity in 2028, subject to readiness.
What the Announcement Means for New Glenn
The October 23 announcement establishes New Glenn’s proposed role in Blue Origin’s revised lunar transportation architecture.
The first crewed campaign would require four launches to place the three transfer stages and Blue Moon Mark 2 lander into Earth orbit.
Those launches represent a coordinated mission campaign rather than four independent lunar landings.
The announcement does not itself establish a new New Glenn return-to-flight date or confirm when the four-launch lunar campaign will begin.
NASA’s immediate development plan calls for the 2027 Earth-orbit demonstration, additional Blue Moon hardware and human-systems testing, and an uncrewed lunar landing demonstration before the planned crewed surface mission in 2028.
