This is the Hermeon Explorer 2. It's meant to go to Moho. God knows if it actually will. (The Hermeon Explorer 1 never left Kerbin's SOI, and killed its entire crew.) It was designed to be launched in three sections, and thanks to design mistakes and a rendezvous that turned into a high-speed collision it only took eleven! It's finally ready, though, albeit surrounded by a swarm of smashed engine bells and the final stages of launchers I didn't remember to deorbit before their probe brains ran out of power.
