The scary part about putting a space station in orbit around Kerbin is viewing all the junk you've left up there and trying to pick an orbit that doesn't intersect with any of it. And the rocket that puts it at that altitude has to be extra careful about any junk it leaves behind, what with it spending time on an identical orbit.
So, after undocking the first part of Clowder Station, commanded by a lonely Jebediah Kerman, Bob Kerman was careful to deorbit his big fuel tank before separating the final lander stage and leaving Jeb in orbit.
The final touch was switching the vessel type to "station" so it shows up with a nice icon in the tracking station. Next step: docking the other half of the thing. A.k.a the hard part.
