Having installed KIS & KAS, I've begun overhauling my LKO space station, mostly in the interest of reducing part count. KSSM-1 was a pilot mission to deliver small storage containers and test servicing techniques. I removed and deorbited surplus struts, but the process was a bit tedious.
The KSSM-2 freighter, still docked on the left side of the illustration, delivered a large permanent storage container, straightened the crooked #2 docking assembly, paved the way for future expansion with Clamp-O-Tron Senior ports, and is about to return to Kerbin carrying extra parts. It brought up equipment which allowed me to detach the upper stage of the rocket that launched the main station and fly it into the ocean. To help with the work, KSSM-3 delivered two small robots (one seen attached to the IMC-250 at lower left) and their docking/storage platform (at upper right, with one unit still attached). They greatly sped up the work by hauling more parts than a Kerbal could carry.
The next mission to this station will replace the many small monopropellent tanks with fewer larger ones and upgrade the lifeboats from their current slightly-better-than-death situation, but first I'm going to fly MSSM-1 to my Munar station. This will combine the payloads of KSSM-2 and KSSM-3 into a single launch. Besides strut removal and ladder installation, I plan to remove one of the science modules (which are only there for looks, this being a sandbox game). Since they're not attached with docking ports and I'd rather not use the fly-something-into-the-station-at-60-m/s servicing technique, this will be a tricky operation.
Also visible is one of the two surviving Mk. I versions of my 7-place shuttle. It still has a decoupler between the command pod and the Hitchhiker Storage Container to drop it and save the command module should things go wrong.
