X owner Elon Musk threw a tantrum on Thursday after being called out for falsely claiming that President Joe Biden deliberately stranded astronauts in space.
During an interview with Fox News' Sean Hannity, Musk claimed that Biden had left two astronauts stuck in space for nearly a year for purported "political reasons."
This caught the attention of European Space Agency commander Andreas Mogensen, who took to X to hold Musk to account.
"What a lie," wrote Mogensen. "And from someone who complains about lack of honesty from the mainstream media."
Musk responded by hurling slurs at the astronaut.
"You are fully r------d," Musk wrote. "SpaceX could have brought them back several months ago. I OFFERED THIS DIRECTLY to the Biden administration and they refused. Return WAS pushed back for political reasons. Idiot."
Mogensen tried offer a more diplomatic reply.
"Elon, I have long admired you and what you have accomplished, especially at SpaceX and Tesla," he began. "You know as well as I do, that Butch and Suni are returning with Crew-9, as has been the plan since last September. Even now, you are not sending up a rescue ship to bring them home. They are returning on the Dragon capsule that has been on ISS since last September."
