Elon Musk Slams NASA Chief Over SpaceX Criticism
Elon Musk has launched a fierce public attack on acting NASA administrator Sean Duffy after Duffy claimed SpaceX is falling behind schedule on the Artemis moon mission. The SpaceX CEO accused Duffy of “trying to kill NASA” and questioned his qualifications in a series of explosive posts.
Key Takeaways
- Elon Musk called NASA’s Sean Duffy “Sean Dummy” and accused him of trying to “kill NASA”
- The conflict stems from Duffy’s comments that SpaceX is behind on Artemis III lunar lander
- Duffy suggested opening contracts to competitors like Blue Origin
- NASA’s Artemis III moon landing mission is now planned for 2027
The Explosive Exchange
In a talkshow appearance, Duffy stated SpaceX was “behind” on developing its lunar landing system for Artemis III and would consider contracts with competitors including Jeff Bezos’ Blue Origin. Musk responded with multiple posts on X, writing: “The person responsible for America’s space program can’t have a 2 digit IQ.”
Musk escalated his criticism, referring to the NASA chief as “Sean Dummy” and claiming he is “trying to kill NASA!” The SpaceX founder also posted a poll questioning whether “someone whose biggest claim to fame is climbing trees” should run America’s space program, referencing Duffy’s background as a competitive speed climber.
What Duffy Actually Said
During a “Fox & Friends” interview, Duffy confirmed SpaceX is “behind schedule” on Artemis III while acknowledging the company as “amazing” that does “remarkable things.” However, he revealed: “I’m in the process of opening that contract up. I think we’ll see companies like Blue get involved, and maybe others.”
Duffy framed this as creating a “space race” between American companies to see who can reach the moon first, emphasizing that President Donald Trump is focused on beating China. “A little COMPETITION doesn’t hurt and it spurs INNOVATION! American companies are going to be able to compete to see which one can get us back to the Moon first,” he wrote on X.
Artemis Mission Timeline
NASA’s Artemis program aims to return humans to the moon. The first uncrewed mission launched in November 2022, but the agency has since delayed its schedule. The first crewed Artemis launch is now set for April 2026, with the Artemis III moon landing mission planned for 2027.
SpaceX and Blue Origin have until October 29 to propose ways to accelerate the project, according to a NASA official. The agency will also seek industry suggestions to “increase the cadence” of moon missions.
