I still prefer UTS Stunehenge.
You are correct. There is solar wind, which is not really wind, but high-speed particles driven by light pressure from the sun.
This is why I think this could be an appropriate name. It refers to a group of people near their Home Star, the advance contingent for a fleet of galactic explorers.
I am not heavily invested in "UTS Windward Phalanx," or any other name, yet. I still think there may be the right one to choose.
Come on, Gang, help me out!
