: Always perform your major ejection burns at the lowest possible point of your orbit.

: If you are refueling at a station, don't refuel at the Mun; refuel at Minmus. Its weak gravity makes it easier to land/take off, and its high orbit allows you to "drop" back toward Kerbin to pick up massive speed before your final interplanetary burn. 3. Hidden Features in 1.12.5

: When leaving the Kerbin system, a gravity assist from the Mun can save you ~200 m/s of delta-V on your way to interplanetary space. 2. Efficiency: The "Oberth Effect"

: Look for the icon on the bottom left (the transfer window icon). It will calculate the exact date and angle needed to reach Duna or Jool so you don't have to guess when to launch.
