Kerbal Scenarios & Missions using the n-body gravitation & angular momentum mod "Principia" NOTE 2022 January: With TeacherGaming closing its doors, the login based KerbalEDU 1.4.5 & 1.3.1 are no longer available. Private Division has released, to current holders of KerbalEDU, the old installer based KerbalEDU 1.2.2. For anyone desiring to use Principia in an EDU setting, I recommend using the most recent KSP (currently 1.12.3) as both Principia & KSP have progress tremendously since 1.2.2 and also since the Principia developers only support the current release of Principia. That said, if you really want to tinker with Principia without support in KerbalEDU 1.2.2 then Principia Cramer and its specific install dependencies (also study the Principia install instructions) was the last version to support KSP 1.2.2. The KSP save files I provided below will not work in 1.2.2 as they are for later versions of KSP. To start, I instead suggest tinkering with the ship in the KSP save posted at: Principia Challenge: Munar Retrograde Rendezvous (1.2.2) [edit 2020 March: expanded this topic to cover EDU related Principia activities rather than just one Mun mission] Table of Contents (= Links to key posts below with details): Principia Mun "Free Return" FlyBy Tips regarding creating scenarios by editing .sfs saves with Principia scimas' RSS Principia "initial state" files for various epochs Principia Challenge: Munar Retrograde Rendezvous (1.2.2)

The challenge: Once in low-Kerbin orbit and you've matched planes with Minmus, position a maneuver-node to allow you, with only one burn, to put your spacecraft on a free-return trajectory around minmus, BUT! also get an encounter with the Mün between escaping from Minmus and Kerbin periapsis. Bonus points if you can have the Mün encounter slingshot you in a way that allows even more gravitational assist maneuvers. Basically, start in low Kerbin orbit matched with Minmus' orbital plane. From that plane-matched low-Kerbin orbit, perform ONE engine-burn with as many gravitational encounters/escapes as possible without any extra engine-burns.
