Single Fuel SSTO Challenge As the name implies this is a challenge about building an SSTO capable vehicle using only a single kind of fuel. There will be four categories: liquid fuel, RCS, solid fuel and Xenon. The last one im not sure is possible but i will keep it as an category if someone manages to build one. What is an SSTO? An SSTO is defined on this challenge as a Vehicle of any shape that does not drop any parts. Therefore things exploding on hitting a cliff or by burning in the athmosphere is allowed and not staging. Rules: No mods, alt f12 or other cheats. You are not allowed to have any other resource on your plane other then the resource of the category you are competing for except electric charge and intake air. You are not allowed to use resource mining or transfering under your mission. Provide picture of plane in SPH with engineers report open, on runway with resource tab open in orbit with your highest kerbin apoapsis and pictures with the various planetary bodies you have visited with your plane. These rules are enforced trough honor and if people can provide sufficient proof of someone breaking them. Scoring: Your score will be: Highest Kerbin Periapsis+Highest Kerbin Apoapsis+Combined Sphere of influence of bodies visited 3 (Kerbol does not count since you are already in orbit of it) Bonus Points and Penalties: Calculated by multiplying final score by combined bonus points +1. Horiontal takeoff: 0.1 Kerbaled: 0.1 No gravity assists: 0.3 Lost parts: -0.5 +0.1 per 10% reentry heating setting Showing that it is possible: (with liquid fuel) Pictures here. I did not try to reach my maximum apoapsis but its the same thing pretty much. High Scores! Liquid fuel: LordFjord-35891080629 RCS: Solid fuel: Xenon: Have fun, also this is my first challenge so im open to suggestions! (mandatory kerbal)
