Isaacman says Artemis III heads to tanking test before 2027 launch

Jared Isaacman told an audience at Kennedy Space Center on Oct. 23, 2026, that Artemis III no longer aims to land astronauts on the Moon and will instead fly as a crewed Earth-orbit mission to practice docking Orion with lunar landers from SpaceX and Blue Origin. Isaacman told employees that Artemis III runs about three months behind schedule, according to Mashable’s Sept. 23, 2026 report, squeezing plans for two Moon landings in 2028; he called summer 2027 the best case for launch. Isaacman and other agency leaders outlined how the agency would return Americans to the lunar surface, aiming for 2028, in NASA’s official Oct. 23 blog post.

NASA’s official blog said Artemis III will carry four astronauts into low Earth orbit next year, testing critical systems for future lunar landings. Artemis IV will be the first Artemis mission to reach the lunar surface, according to NASA’s official blog.

The Artemis III crew announced by NASA consists of Commander Randy Bresnik, Andre Douglas, Frank Rubio, and European pilot Luca Parmitano. This crew assignment followed the February architecture overhaul.

The redesign pushed aside the Gateway lunar station project, planned to be a lab and pit stop, and turned NASA toward a moon base on the surface. Isaacman said keeping Gateway would have let China move ahead with landers carrying rovers and hopper drones, possibly cutting off access to the most desirable spots on the lunar surface. He said the U.S. did not have those drone capabilities in development until recently.

NASA expects its moon base at the lunar south pole, an area roughly the size of Virginia, where deep shadowed craters may hold ancient ice and other frozen material. Using those resources to make water and fuel could help astronauts skip regular resupply trips from Earth and become more self-sufficient.

In his email, Isaacman said Artemis III could launch in summer 2027, keeping two lunar landing opportunities open for the following year, though he called that the best-case scenario. NASA is working with suppliers and subcontractors on delayed components, including valves and rocket steering parts, to get them back on track, and is building some hardware in-house to speed up production. Isaacman disclosed this in his Sunday email as part of the schedule pressure on Artemis III. NASA confirmed to Mashable the authenticity of Isaacman’s email to employees about Artemis III scheduling.

Isaacman said Artemis III is headed for a year-end tanking test before a summer 2027 launch. He stated that when Artemis III flies next year, NASA will exercise strengthened rocket capabilities and test interoperability needed before the next mission. Isaacman said the moon campaign is not about merely getting there and planting a flag, but about making sure America can actually stay when it returns to the Moon. This was reiterated in his Sunday email to employees and reflects the shift from flags-and-footprints to sustained presence.
