The issue recently sparked a heated online exchange between Musk and Danish astronaut Andreas Mogensen, whom Musk called "fully retarded." Retired astronauts Scott and Mark Kelly and Chris Hadfield defended Mogensen.
One astronaut who backed Musk however was Wilmore, who offered contradictory statements in last week's press conference.
"I can only say that Mr. Musk, what he says is absolutely factual," he said, seemingly endorsing the SpaceX founder's version of events, before adding "politics is not playing into this at all."
"We have the utmost respect for Mr. Musk, and obviously respect and admiration for our president of the United States, Donald Trump. We appreciate them... and we're thankful that they are in the positions they're in," he continued.
The Crew-10 team consists of NASA astronauts Anne McClain and Nichole Ayers, Japan's Takuya Onishi, and Russia's Kirill Peskov.
