As work on President Donald Trump‘s Space Force gets underway, a retired American astronaut with more time clocked in space than any other human called the idea totally unnecessary.

Scott Kelly, a 20-year veteran of NASA with 25 years spent in the military, doubted the importance of Trump’s initiative in an interview with CNN’s Brooke Baldwin Thursday and suggested his colleagues find the idea to be silly.

“I know the people that I have talked to, there’s been a little bit of eye rolling going on with this,” he said. “And, you know, the only person you hear promoting this is the president, so [it would] be nice to get a little more of a buy-in from the experts and it doesn’t seem like we have that.”

Kelly also noted he hasn’t heard anyone discuss a need for such a military addition, wondering what made Trump feel that was the case.

“I don’t know a lot about the president’s motivations on this,” Kelly said, adding, “I don’t think it’s necessary. Space is an environment that we’re supposed to work together peacefully [in], and I think we’ve demonstrated that.”

While Kelly acknowledged there may be a conceivable need for a space force in the future, he said “this idea seems to have come from one person who is not a space or military expert,” clarifying that he meant “the president, of course.”

“I kind of wish we were fighting the wars we currently have, maybe, you know, the cyber warfare we’re currently in, focus on that, because I think that is much more a threat to our democracy and our way of life right now,” he said. “If the threat to our elections, then a future, you know, science fiction warfare of the future.”
