Acting NASA Administrator Sean Duffy says it's time for the agency to focus on the moon and Mars, not the "smorgasbord of priorities," like climate science, the agency has been directing its resources.

In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United States to gain a foothold on the moon by the time China plans to land the first taikonaut,

The reactor would launch to the moon by 2030, according to a directive by acting NASA Administrator Sean Duffy that was sent to NASA officials in July and obtained by NPR. It's an ambitious target that has some in the scientific community concerned about high costs and a potentially unrealistic schedule.

Acting NASA Administrator Sean Duffy has directed the agency to fast-track plans to put a nuclear reactor on the moon.

In their report, Lal and Myers estimate it would cost about $800 million annually for five years to build and deploy a nuclear reactor on the Moon. Even if DoE support can prevent NASA's staffing cuts from kneecapping the project, its feasibility will hinge on if the Trump administration ponies up the cash to execute on its own bold claims.

NASA’s Artemis campaign is a bold series of missions to take humans back to the moon, and those astronauts will get there thanks to help from rocket engines mad

Transportation Secretary Sean Duffy, the interim NASA administrator, proclaimed that the U.S. needs to ‘get our act together’ when it comes to the ongoing race to the moon and Mars. To do this, Duffy wants the U.

South Korea's KASA is just one international space agency that will fly cubesats on the mission; Germany's DLR will also contribute its TACHELES cubesat. While Artemis 2 will send astronauts around the moon, the cubesats will have their own science objectives.
