According to recent reports, NASA's Artemis III mission, the bridge to the next American moon landing, is approximately 90 days behind schedule, according to an email by NASA administrator Jared Isaacman.Â
Although final stacking of the boosters and core stage is being completed, the main point of failure is the landers. With Artemis III built around an Apollo 9 mission profile, with the Orion capsule docking with the two lunar landers, the landers must be ready. Unfortunately, both Blue Origin and SpaceX's landers have not been completed and may not be completed by the mid-2027 deadline.
This could mean significant delays to both Artemis III's low Earth orbit docking test, and future missions for lunar exploration and the start of NASA's lunar base. Artemis IV, V, and VI still heavilly rely on lander capabilities for effective crew, cargo, and base transport.
