The Constitution enumerates the branches of the military. "Space Force" isn't one of them. "Air Force" isn't, either.
It doesn't really say much about branches of the military at all, but does only specifically mention the Army and Navy.
Article II - Executive Branch
Section 2 - Powers
The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices, and he shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment.
"Army" is only mentioned that one time, and "Navy" is mentioned only one more time:
Article I
Section 8 - Powers of Congress
To provide and maintain a Navy;
Interesting that Congress seems not be be tasked with providing and maintaining the Army!
