Gets two crew to orbit. If I didn't hate part clipping so much, I could probably put a mk1 can in the cargo bay somewhere and get three crew up there, but ultimately my goal was just to build a teeny tiny SSTO. This one uses RAPIERs to achieve a long suborbital trajectory, then fires the ion engines to achieve orbit. From there it has plenty of dV for rendezvousing or whatever you might want to do in orbit, and carries a little extra LF for zipping around in-atmo after you reenter. Surprisingly the 'test flight' of this had a use, as I needed to get two pilots down from my station.
It's called 'Sunny' because it's best to launch this thing at dawn or so to maximize initial ion burn time. Once you're in orbit things are a little more flexible. (I should add more batteries.)
