On Wednesday, July 15, 2026, NASA published new operational parameters for its upcoming Artemis III demonstration mission scheduled for 2027. Pivoting from its original lunar landing objective under a sweeping strategic reorganization of the Artemis program finalized earlier this year, the mission will instead serve as a low-Earth orbit (LEO) docking and systems integration flight to validate dual commercial lander platforms.

The uncrewed or prototype Human Landing System (HLS) vehicles will launch on commercial rockets, while the four-person crew will ascend to LEO aboard the Orion capsule via the Space Launch System (SLS).
Low Earth Orbit Flight and Docking Specifications
To systematically prepare for a crewed lunar landing target in 2028, the test flight will execute highly specific docking maneuvers and vehicle control handovers in orbit:
- Orbital Altitude: The integration campaign will occur in a circularized low-Earth orbit at a baseline altitude of approximately 460 kilometers.
- Blue Origin Docking Mechanics: Orion will execute a lateral docking maneuver along the side of the Blue Moon Mark 2 prototype, adjacent to the lander’s crew cabin.
- SpaceX Docking Mechanics: Orion will perform a nose-to-nose docking procedure with the Starlink-linked Starship Version 3 HLS test article.
- Guidance and Software Handover: During the Blue Moon docking phase, Orion’s flight software will actively control the integrated stack. Conversely, during the SpaceX phase, Starship’s onboard systems will assume primary control over the combined spacecraft dynamics.
Shared Industrial Goals
The dual-docking campaign represents the first time NASA will actively integrate hardware and software interfaces from both of its HLS providers simultaneously during a single mission.
“Each human landing system provider has taken a different approach to the Artemis III mission,” stated Steve Creech, program manager for the Human Landing System Program at NASA’s Marshall Space Flight Center. “Ultimately, SpaceX and Blue Origin have put forward a list of aggressive objectives and goals intended to complement upcoming uncrewed demonstration missions at the Moon so that we can gain both understanding and confidence.”
Path to the 2028 Lunar Landing
Data captured during the LEO trials will validate critical life support, electrical, and communication interfaces before attempting deep-space missions. Following the completion of the docking exercises, the crew will return to Earth using an upgraded ablative heat shield block designed to withstand high-energy atmospheric reentry profiles. This orbital rehearsal clears the path for the first crewed landing on the Moon’s South Pole, currently manifested for the Artemis IV mission in early 2028.
