Inspired by a few comments about the greatest feat ever accomplished in a Correlian tramp freighter. The Challenge: Achieve an encounter (fly through the SOI) with every major body in the Kerbolar system. FYI, that's Moho, Eve, Kerbin, Duna, Dres, Jool, and Eeloo. Do it with just ONE crewed craft. Do it either in order of increasing orbit from Kerbol (innermost to outermost), or in decreasing order of orbit (outermost to innermost). Make as many refuelling stops as you want, but your refuelling pods must be on station prior to launching your challenge craft. Land safely back on Kerbin or dock with a station in orbit of the planet. Do the entire challenge in twelve Kerbin years MET on the challenge craft. The Rules: Fuel pods must be on rails. No manoeuvering of them once they're on station. Docking manoeuvres must be performed solely by the challenge craft. No OP engines. Use your own judgement and try not to cheat the challenge by using quantum vacuum thrust or warp drive. In fact, QVT and warp drive are the only methods prohibited. There ya go. All other parts and mods are valid. No Hyperedit* or infinite anything. *You may Hyperedit the fuel pods into place *before* launching your challenge craft, but once you do launch that ship, no more Hyperedit! **ESCAPE CLAUSE: Running out of fuel mid-burn isn't necessarily a run-ender. You MAY launch a CREWED fuel pod to rendezvous with your challenge craft and refuel it. HOWEVER, the clock does NOT stop and you are NOT allowed to launch your crewed fuel pod in anticipation of running out of fuel to beat the Fuel Stop penalty. And your crewed fuel pod MUST return to Kerbin. No unbreakable joints, part welding or any of that malarky. You have 12 years to complete the challenge. On the tick of 12 Kerbin years, your attempt is over. Scoring: Each year MET elapsed: -1 Each refuelling stop: -1 Each verified encounter: +2 Safe landing on Kerbin: +2 Docked in Kerbin orbit: +1 Did it in increasing order: +3 Did it in decreasing order: +5 SURPRISE BONUS: Drop a probe into low orbit of each body: +2 each SURPRISE BONUS: Soft land a probe on any body in each planetary system: +3 each Other points additions TBD by discussion. Badge: (Challenger's Note: I've done a swan dive from Kerbin orbit to the surface of the Sun, it took 27.8 game-days. I do not consider this challenge impossible. Just really, really tricky.) Note: Using the following map, I've napkinned the total dV requirement using orbital transfers (not overburning or using slingshots) at around 27km/s. Aside from getting into Kerbin orbit, I believe this *is* possible using ion drive (but I'm not brave enough to test this theory). It's certainly possible using nuclear engines in the transfer burns (plus the fact that the LF tanks are lighter than the LFO ones, kinda makes it a no-brainer as far as reaction mass efficiency goes). The Luvodicus Super Atomic engines and the Poseidon's Revenge, even though they both use oxidiser, would ace this challenge on just eight FL-T800 tanks. If only I could get them working in 1.x. Leaderboard: 1. Nefrums in his stock "Falcon": 4Y 61D and some amazing manoeuvering (orbital capture!) for a score of 13.
