KSP Artificial Gravity Station

I've seen other artificial gravity rings in ksp and I wanted to make one of my own. At some point I want to make a larger station for testing rovers on various simulated planets. If Duna is to far away to test on why not make some Duna in LKO? Music: Death & Rebirth - Hanami    • Death & Rebirth | Hanami     / deathandrebirth
