Here's my jellynator, an almost ssto rocket, equipped with 24 LV-T45 and one Mainsal engine, four jumbo and 8 FL-T800 fuel tanks. It used to have eight radial engines around the mainsal but they overheated the mainsal and had a too low specific impulse.

My plan is to somehow attach (at least) three of those things together to create a lower stage for a ridiculously big cargo rocket to launch stuff towards other planets.
And here's my space station KOS. currently it has only three modules (living, core and electric) but I am slowly expanding it.
Living module connects with the core. The fastest (and first successful) docking I've ever made, only 34 minutes from launch to dock. Could have been done probably in under 30 minutes but I'm not too fast at docking.

And the electric module, Jeb and Bob move to the station while Bill returns to kerbin. Crew now eight kerbals.
