Trump again nominates Musk ally Isaacman to be Nasa chief

US President Donald Trump on Tuesday nominated billionaire entrepreneur and private astronaut Jared Isaacman to head Nasa, again tapping the close associate of Elon Musk to lead the US space agency.

The nomination, announced by Trump on Truth Social, came six months after the president withdrew his initial nomination of Isaacman to lead Nasa amid a bitter row with Musk.

If confirmed by the Senate, Isaacman would replace Transportation Secretary Sean Duffy, who has served as interim administrator of the National Aeronautics and Space Administration.

“Jared’s passion for Space, astronaut experience, and dedication to pushing the boundaries of exploration, unlocking the mysteries of the universe, and advancing the new Space economy, make him ideally suited to lead NASA,” Trump said in his post.

Isaacman in May was yanked as the choice to lead Nasa just as Musk and Trump were falling out over the president’s “big beautiful” domestic policy mega-bill.
