NASA Maps 17-Day Artemis III Test Flight for Summer 2027

NASA Administrator Jared Isaacman outlined a 17-day orbital test mission for Artemis III, scheduled for summer 2027, that will serve as the final certification for two competing lunar landers. Speaking at a two-hour press conference at Kennedy Space Center on Oct. 23, Isaacman, along with Associate Administrator Amit Kshatriya and Artemis Program Manager Jeremy Parsons, described the sequence as the most complex flight NASA has ever planned.

The mission sequence begins with an uncrewed Blue Origin New Glenn rocket launching the Blue Moon lander into orbit. NASA’s Space Launch System rocket will then launch separately, carrying four astronauts aboard the Orion spacecraft. The crew will dock with the Blue Moon, enter the vessel, and test its life support and environmental controls before returning to Orion. They will subsequently rendezvous with a SpaceX Starship lander, which will carry only a docking port and no life support, to verify the connection between the two vehicles.

This dual-lander strategy stems from technical limitations and contract decisions made in 2021 and 2023. A single spacecraft capable of landing, launching, and reentering Earth’s atmosphere is too heavy for the job. Instead, the mission divides the work between a lightweight landing vehicle and an orbiting mothership. SpaceX won the initial contract for its 165-foot Starship lander in 2021. Blue Origin secured a second contract in 2023 for the Blue Moon, a design closer to the low-slung Apollo lunar module.

Both companies face hurdles before they can certify their vehicles for the 2028 Artemis IV landing. SpaceX has launched 14 Starships since 2023 but reached Earth orbit for the first time only in September 2026. Blue Origin’s New Glenn rocket experienced a major setback in May 2026 when a test of its first stage engines caused a massive explosion that partially destroyed the launch pad infrastructure. Parsons noted that over 100 NASA team members are currently working with Blue Origin to accelerate its return to flight.

Parsons stated that astronauts will open the hatch of the Blue Moon to evaluate atmospheric pressure, emergency scenarios, and dual vehicle control. He emphasized that the mission will stress-test Mission Control teams. The outcome of Artemis III will determine which lander flies crew on Artemis IV, though both vehicles must still complete an uncrewed lunar landing and liftoff to prove their reliability.

NASA has 18 months between the Artemis III launch and the Artemis IV target date of late 2028. Isaacman expressed confidence that this timeline is achievable, despite the agency's history of shifting priorities since the Apollo program. He acknowledged that the competition with China has intensified, requiring NASA to execute these complex tests without slipping into 2029.
