Space is pitch black, so why will US Space Force members wear camo uniforms?

The void of space is pitch black with pinpoints of distant light. So why will some members of the newly-formed U.S. Space Force be clothed in green and brown camouflage?

It's a question that many asked on social media after the Space Force tweeted a photo of its utility uniform on Friday. 

"Camo in space?" one commenter wrote, musing about wasted taxpayer dollars.

The Space Force had a quick answer: The service members wearing the uniform will be working on the ground, and using existing uniform designs is saving taxpayer dollars. 

In another explanation, the official Space Force Twitter account said the uniforms will be worn by Space Operators, working from Earth alongside service members in the U.S. Air Force and U.S. Army.

Background: Trump signs defense bill that creates Space Force

The Space Force was established in December after President Donald Trump had long said it was a necessary part of the U.S. military, citing threats from China and Russia and the nation’s reliance on satellites for defense operations.

"Space Com will defend America's vital interest in space, the next war-fighting domain," Trump told reporters in August. "The dangers to our country constantly evolve, and so must we."   

Trump said U.S. adversaries are weaponizing "Earth's orbits with new technology targeting American satellites."
