Elon Musk attacked Sean Duffy, the US secretary of transportation, on Tuesday in a series of posts on X, accusing him of trying to “kill NASA”, suggesting he should be fired and calling him “Sean Dummy”. The posts intensified a long-running feud between Duffy, who is also the acting head of Nasa, and Musk, whose company SpaceX is central to the US space program.
Musk’s tirade against Duffy followed a statement from the transportation secretary on Tuesday that Nasa would reopen contracts for the agency’s Artemis mission to land humans on the moon, which SpaceX had previously secured. Duffy said that SpaceX had fallen behind on its timelines. Duffy suggested the contract might go to another billionaire’s rocket company, Jeff Bezos’s Blue Origin.
