NASA has reconfigured its upcoming Artemis III mission to launch four astronauts into low Earth orbit next year for a complex two-week docking test with commercial lunar landers, maintaining the agency’s overarching target to return humans to the lunar surface in 2028.
The space agency laid out its revised concept of operations during a press conference at Kennedy Space Center anchoring on a summer 2027 launch window for Artemis III. The mission will no longer land astronauts on the moon directly. Instead, it functions as a rigorous orbital dress rehearsal designed to evaluate rendezvous procedures, life support systems, and crew survival gear before humanity attempts its first lunar landing in more than half a century.
NASA Administrator Jared Isaacman led the update alongside Associate Administrator Amit Kshatriya and Artemis program manager Jeremy Parsons. During the briefing, Isaacman stated that the space agency is focused on improving efficiency, asserting that great achievements simply do not require more time and more money. Pointing to progress in processing work tied to the mission, Parsons noted that teams have seen preparation times cut in half in some cases, with booster segment preparation and booster stacking operations reduced by 20%.
Three Powerful Rockets and a Choreographed Orbit in Low Earth Orbit
The mission requires a synchronized launch campaign utilizing three heavy-lift rockets departing from Florida’s Space Coast. According to The Associated Press reporting from Cape Canaveral, the flight plan involves four crew members: NASA astronauts Randy Bresnik, Frank Rubio, and Andre Douglas, alongside European Space Agency astronaut Luca Parmitano.
The sequence begins when Blue Origin launches its Blue Moon lunar lander into low Earth orbit using a New Glenn rocket. Following the Blue Moon test article launch and confirmation that the vehicle is healthy and ready for joint operations, NASA plans to launch Orion on top of the Space Launch System from Kennedy Space Center only days later. Parsons noted that NASA has no contingency plans to send Blue Moon to space onboard an alternate vehicle, and that the design for the Artemis III lander test article is in good shape following design reviews. For its accelerated crewed lunar landing mission, Blue Origin will defer propellant transfer and use three transfer stages to send the Blue Moon Mark 2 Alpha Lander to the Moon based on existing Mark 1 and Mark 2 hardware.

Once aloft, Orion will initially enter an elliptical Earth orbit. According to Parsons, SLS will deploy Orion into a highly elliptical orbit, one that gets as close to Earth as 18 miles and as far away as 1,122 miles. The crew will spend time checking out Orion and its environmental controls. Orion will connect to a port beside Blue Moon’s crew cabin at an altitude of roughly 270 miles above Earth, allowing the astronauts to open the hatch, enter the lander, and evaluate environmental controls and life support systems.
Starship Docking Tests and the Push for Artemis IV Readiness in 2028
Following the Blue Origin exercises, SpaceX will launch a version of its Starship into orbit. Orion will detach from Blue Moon, adjust its trajectory, and align its forward docking system with the one at Starship’s nose in a slightly lower orbit. NASA plans to evaluate spacecraft controllability, communications, integrated software performance, and the dynamics associated with docking and undocking operations. On SpaceX landings, Starship will likely dock with the NASA capsule in Earth orbit and propel it to the moon as a push maneuver.
The crew will not enter the Starship during the mission, but it gives us critical data and allows us to really understand the forces of docking, how we’re going to push, how we’re going to work together.

As astronaut Frank Rubio noted to The Associated Press, setting up a long-term presence makes these missions incredibly ambitious compared to Apollo-style commuter flights. Axiom will test new sortie suits on the International Space Station next year ahead of these deployments.
Weighing Options Between Competing Providers as Timelines Shift
NASA has deliberately preserved optionality regarding which commercial partner will secure the first crewed landing contract for Artemis IV. Agency leadership emphasized that both Blue Origin and SpaceX are marching toward lunar landing missions in 2028, with NASA keeping its options open as long as possible before choosing between SpaceX and Blue Origin as a tiebreaker for the Artemis IV lunar lander. Artemis III will serve as the deciding factor between the two potential lunar landers.
Regardless of who goes first, both providers are planning for lunar landing missions in 2028.

Refueling requirements have been a point of evaluation, following remarks by Charlie Precourt of NASA’s Aerospace Safety Advisory Panel suggesting a Starship landing could take around 22 refueling launches, while Elon Musk pushed back with an estimate of 6 to 8. Parsons noted that efficiency gains and upcoming transfer demos should bring tanker counts closer to the high single digits. Supply chain constraints for lander components and recent manufacturing milestones such as the construction of Starship Cabin 1 highlight the intense engineering push underway as teams race to meet the 2028 lunar return objective.
