The Nebula Rocket carrying the Mun Spaceport adapters launches!

At a 200k apoapsis, the first stage turns around, and returns to Kerbin! Meanwhile, the second stage ejects it’s fairing…

…and heads to Mun!

Circularizing orbit around Mun, the remotely piloted vehicle rendezvouses with Mun Spaceport until…

The tiny craft arrives at the massive orbital research and refueling depot!

“Mission Control – we show the spacecraft at station keeping – we’re ready for control handover!”

-Summer

Control of the upgrade modules is given to Mun Spaceport, and Summer (carefully!) pilots the three small modules into position!

The first Module goes on in an unoccupied bay…

Then the second module goes on opposite it!

“Ready for the last module! This one will be a little tricky, it’s going on the underside of the station!”
-Summer

Depsite some difficulty, Summer flawlessly docks the small module to the underside of the station!

With all three adapter modules in place (and their disposable installation craft drifting safely away) Mun Spaceport is ready for future spacecraft!
