Mon Oct 27 06:20:00 UTC 2025: Musk Unleashes Twitter Tirade Against Transportation Secretary Over NASA Moon Mission Concerns

[City, State] – Elon Musk, CEO of SpaceX, launched a scathing attack on Transportation Secretary Sean Duffy on Tuesday, using his social media platform X to hurl insults and question Duffy’s qualifications following the secretary’s remarks about potential delays in SpaceX’s lunar lander development.

Duffy, in a recent interview with CNBC, expressed concerns that SpaceX’s progress on its $2.9 billion contract to build the lunar lander for NASA’s Artemis III mission was lagging behind schedule. He suggested opening up the contract to competition from other space companies to ensure the U.S. remains on track to return humans to the moon before China.

Musk responded with a barrage of derogatory posts, calling Duffy “Sean Dummy,” implying he had a low IQ, and posting memes mocking his background as a former world champion lumberjack speed climber. “Should someone whose biggest claim to fame is climbing trees be running America’s space program?” Musk questioned in one post.

NASA’s Artemis III mission, currently slated for mid-2027, aims to land astronauts on the moon. Duffy stated that while he recognized SpaceX’s achievements, delays could jeopardize the mission’s timeline.

The online feud also touched upon the potential return of Jared Isaacman, a SpaceX customer who has flown to orbit on SpaceX capsules, as a candidate for NASA Administrator. Musk reposted others praising Isaacman. Isaacman told CNN he has “never expressed confidence about renomination at any point” and that he has “a lot of respect for Secretary Duffy and I have always enjoyed the time I’ve spent with him.”

A spokesperson for Duffy said the Transportation Secretary “never said he wants to keep the (NASA) job himself.” The spokesperson added that Duffy has suggested NASA “might benefit from being part of the Cabinet, maybe even within the Department of Transportation,” but reiterated he has not said he would like to become NASA’s permanent leader.“The President asked him to talk with potential candidates for Administrator, and he’s been happy to help by vetting people and giving his honest feedback,” the spokesperson said.
