Andreas "Andy" Mogensen had shared on X a Fox News clip featuring Mr Musk and US President Donald Trump, where Mr Musk claimed NASA's Butch Wilmore and Suni Williams were left stranded on the orbital outpost for "political reasons" by Joe Biden, and that the new administration was now coming to the rescue. "What a lie. And from someone who complains about lack of honesty from the mainstream media," wrote the 48-year-old European Space Agency astronaut, who has flown to the ISS twice, including aboard a SpaceX Crew Dragon capsule during a 2023 mission. Musk responded by calling Mogensen "fully retarded," adding that "SpaceX could have brought them back several months ago" and that he had made such an offer to the Biden administration, without elaborating on what that offer entailed. Mr Wilmore and Ms Williams flew to the ISS in June aboard a Boeing Starliner for what was meant to be an eight-day test mission to certify the new spaceship. What a lie.
