In a groundbreaking announcement, Isaacman revealed that NASA has decided to abandon its plans for a lunar orbit space station. Instead, the agency will invest $20 billion in constructing a base on the moon’s surface, utilizing components from the now-canceled space station.

This revelation follows a major update to NASA’s Artemis moon return program made in February, aiming to expedite the timeline for launches as the agency targets a lunar landing in 2028.

The revised strategy includes introducing the Artemis III mission in mid-2027. This mission will test critical rendezvous and docking technologies with lunar landers being developed by SpaceX and Blue Origin within low Earth orbit. If successful, the Artemis IV mission is set to follow, marking the return of astronauts to the moon. The mission will involve a commercially-developed vehicle docking with the Orion spacecraft to facilitate the lunar landing.

“If any issues arise, our goal is to return to sea within hours rather than days,” said Isaacman regarding the Artemis III test flight. “The insights we gain will be invaluable for Artemis IV in 2028, where we aim to land astronauts on the moon while concurrently constructing a lunar base.”

Williams, who is set to retire from NASA in December 2025, emphasized the importance of the International Space Station (ISS) as a vital testing ground for future long-duration lunar missions.

“Since humans have been aboard the ISS since 2000, we’ve gained extensive knowledge,” Williams stated. She noted that long-term stays in these orbiting laboratories have taught NASA how to combat the adverse effects of microgravity on the human body through exercise and nutrition.

“Our research aboard the space station spans stem cell studies, DNA sequencing, and innovations in engineering, manufacturing, and biomedical engineering,” she added. “The ISS has equipped us with numerous technologies that will be crucial for our extended presence on the moon.”

With a wealth of experience in long-term space missions, Williams has completed three trips to the ISS, totaling 608 days in space. Her most recent journey occurred last year when she and NASA astronaut Butch Wilmore unexpectedly spent over nine months at the ISS due to complications during a test flight of Boeing’s Starliner capsule.

When asked about their willingness to participate in a lunar trip if the opportunity arose, both Williams and Isaacman expressed enthusiasm.

“I believe our response would be unanimous,” Isaacman said with excitement. “Yes!”
