NASA Administrator Confirms: SpaceX Starship and Blue Origin Blue Moon Lunar Landers Not Ready Until Late 2027
Summary: On April 27, 2026 (EST), NASA Administrator Jared Isaacman told the House Appropriations Committee's NASA budget hearing that both SpaceX's Starship Human Landing System (HLS) and Blue Origin's Blue Moon lunar lander contractors have confirmed neither system will be ready until late 2027 at the earliest, for Artemis III Earth-orbit rendezvous, docking, and interoperability testing. Earlier in the month, the Artemis II mission successfully completed a crewed Orion spacecraft lunar flyby.
Both Lunar Landers Delayed to Late 2027
On April 27, 2026 (EST), NASA Administrator Jared Isaacman addressed the House Appropriations Committee during a NASA budget hearing, providing an update on the进度 of Artemis lunar landers. Both the SpaceX Starship HLS and Blue Origin Blue Moon lander contractors have confirmed to NASA that their landers will not be ready until late 2027 at the earliest.
This means the lunar landers originally planned for the Artemis III mission—which aims to land two astronauts at the lunar south pole—will not be available on the earlier anticipated schedule, further pushing back the mission's implementation.
Artemis II Successfully Validated SLS and Orion Reliability
During the hearing, Isaacman also highlighted the success of the Artemis II mission earlier in April 2026. The Artemis II mission nearly perfectly completed a crewed Orion spacecraft lunar flyby, validating the reliability of the Space Launch System (SLS) rocket and the Orion crew and service modules. This success lays the foundation for the subsequent Artemis III mission, but the lander delay remains the primary bottleneck.
Lander Preparation Status
According to contractor reports to NASA:
- SpaceX Starship HLS: Must complete Earth-orbit rendezvous and docking tests, plus interoperability validation with the Orion spacecraft
- Blue Origin Blue Moon: Must complete development and a series of tests, also facing schedule pressure
Both landers employ innovative designs significantly different from traditional approaches. SpaceX's Starship needs to complete on-orbit propellant transfer tests, while Blue Origin needs to validate its lander's compatibility with the SLS/Orion stack. These tests require substantial time to complete.
Background: Artemis Program Shifts from Ambitious to Pragmatic
NASA's Artemis program has undergone a shift in recent years—from "ambitious schedules" to "steady pragmatism." Artemis I completed an uncrewed lunar flyby in 2022, Artemis II completed a crewed lunar flyby in April 2026, and Artemis III's lunar landing has been repeatedly delayed due to lander development progress. NASA Acting Administrator Sean Duffy has stated that Artemis III will proceed according to "engineering readiness" rather than "political schedules."
