NASA chief spoke to SpaceX official about Musk’s Twitter “distraction.”

NASA Administrator Bill Nelson said he pulled the head of SpaceX aside to raise concerns about Elon Musk’s Twitter controversies that could affect the space company.

Nelson said he asked Gwynne Shotwell, SpaceX’s president and chief operating officer, earlier this month if the Twitter controversy would affect business at SpaceX, a crucial NASA partner.

“Tell me the distraction Elon can have on Twitter won’t affect SpaceX,” Nelson said. according to NBC News.

Shotwell replied that “you have nothing to worry about,” according to Nelson’s account of the conversation.

Nelson told NBC News that he was not concerned about SpaceX, which Musk runs as CEO, and that Shotwell assured him.

“I hugged her with a smile on my face, because I know she’s doing this thing. She’s running SpaceX,” he said.

Nelson was speaking to reporters after a press conference Sunday just hours after the Orion capsule returned to Earth, completing the Artemis 1 mission. His comments about Shotwell and SpaceX were also reported by an Ars Technica editor.

SpaceX carries NASA astronauts to the International Space Station and has saved the space agency billions of dollars.

SpaceX is also working with NASA on future Artemis missions, which will land astronauts on the Moon for the first time in nearly 50 years.
