This week, we challenge you to... build a space station!
Primary: Build a station by docking at least two Wayfarer habitat modules together in orbit around Kerbin.
Secondary: Add a deployable solar panel truss and a fuel depot tank to your station.
Jeb: Dock a transfer tug to your station and send it to orbit another planet.
Val: Send a lander to your station that is reusable on the body the station is now orbiting.
