What Does Bill Nelson Say About China's Lunar Ambitions?

Former NASA Administrator Bill Nelson writes in a forthcoming memoir that China intends to "dominate the high ground of the twenty-first century" through its space program, and that the United States is not currently favored to win the emerging race to the Moon, according to Ars Technica, which obtained details of the book.

Who is Bill Nelson and what is the book?

Nelson, a former U.S. senator and congressman from Florida, flew as a mission specialist on a space shuttle flight in 1986 and led NASA from May 2021 to January 2025 under President Biden, Ars Technica reports. His memoir, titled "Space Odyssey," is scheduled for publication by Harper Horizon in January 2027 and focuses largely on his congressional space policy work and his NASA tenure, according to the outlet.

What did the Chinese spy balloon incident reveal, according to Nelson?

Nelson recounts that in early 2023, NASA assisted the U.S. military as a Chinese spy balloon crossed the United States, drawing on the agency's experience mapping the stratosphere and modeling atmospheric currents to help authorities down it without endangering people on the ground, Ars Technica reports. "What many Americans first registered as a balloon violating our airspace was really a warning that the next great rivalry will not be fought on land or sea but the skies above us and even beyond our atmosphere," Nelson writes, according to the outlet. He adds that the episode offered "a window into the new space race that is swiftly approaching its most urgent phase, with the stakes even higher than the Cold War contest."

Why does Nelson say China cannot be trusted as a space partner?

Nelson has long viewed China as a threat over concerns about technology theft from the West, according to Ars Technica. Unlike his predecessor Charlie Bolden, who led NASA under President Obama, Nelson backed the Wolf Amendment, which restricts NASA cooperation with China's space program, the outlet reports.

"China is not a partner to be trusted," Nelson writes. "Partnership requires trust, and trust is founded on transparency. With China, despite repeated efforts to build verifiable, rules-based cooperation and set commonsense guard rails for engagement, there has never been much of either."

How close is the competition for the Moon?

Nelson identifies the Moon as the immediate flashpoint, with both NASA and China pursuing crewed landings and long-term settlements, according to Ars Technica. Despite criticizing the Trump administration elsewhere in the book, Nelson aligns with current NASA Administrator Jared Isaacman in describing the competition as urgent and requiring more than symbolic "flags-and-footprints" missions, the outlet reports. Nelson writes plainly that "America is not the obvious favorite," according to Ars Technica.

What to watch

• Publication of "Space Odyssey" by Harper Horizon in January 2027, which may detail further specifics on NASA-China competition.
• Statements from current NASA Administrator Jared Isaacman on lunar settlement timelines.
• Any changes to Wolf Amendment enforcement affecting NASA-China contact.
• Chinese government announcements on crewed lunar landing or base plans.
