Val level VTHL SSTO with 35t payload capacity.
I had a lot of fun with this week's challenge! I don't normally build Mk3 SSTOs, lets alone with VTHL capabilities. I came across a few minor bugs, like my power module wanting to flip out a little bit. I think it was getting confused with the medium sized docking ports on each end and within such close proximity to one another. While trying to dock the two modules together, the docking acquire force would only let me within 7m of my habitation module, and then it would repel me as if the polarities were the same. I just spun the module around and docked from the other side and it worked itself out.
The two space station modules I built were a 5-kerbal habitation module complete with solar panels, RCS and a direct communication link to KSC. The second module is a power generating and communications module, with a medium sized RTG and both direct and relay communications capabilities.
