I agree, guardians isn’t a good name. How about “Space Nerds”?
Maybe...
X-men
Astromen
Spacemen, Space non-binary units
Cosmokids
Stellars
Satellitemen
Or, maybe, just call them soldiers, or “the men and women of the Space Force”
Please understand, I am a former Army infantry officer who learned to fly satellites. As a slimy Beltway Bandit, the space arms race is my business. This stuff is deadly serious to me.
On this past Wednesday morning, the Russians conducted a live fire test of their new direct-ascent anti-satellite missile. We need to get our stuff together fast.
