At a Thursday hearing with Senators, a panel of top military leaders tried their best to convince lawmakers that now is the time to start setting up such a plan, which has been repeatedly championed by President Trump.
"We're going to have a Space Force some day," said Air Force Gen. John Hyten, the head of the U.S. Strategic Command. "I think what the committee has to decide when that is going to happen."
It's an idea which certainly has received a lot more attention because of President Trump's support for a Space Force.
"That's the next step, and we have to be prepared," President Trump said about space in a February event in the Oval Office. "Our adversaries and, whether we get along with them or not, they're up in space."
But the President's moves to create a Space Command, to sign a Space Force Directive, plug it repeatedly at political rallies, and talk about it with top defense officials has not changed the political dynamic on it for lawmakers in the House and Senate.
"Everybody is excited," Mr. Trump said of the Space Force in October of 2018 during a visit to Luke Air Force Base in Arizona.
Everybody it seems, except many members of Congress - as all systems are not 'go' at this point.
"You can tell that we're all wrestling with it, we're kind of struggling with it," said Sen. Dan Sullivan (R-AK) told military leaders.
