: Always perform your major ejection burns at the lowest possible point of your orbit.
Since you are on the final GOG version (1.12.5), you have access to the and Alarm Clock integrated into the base game, which are essential for the advanced techniques below. 1. The "Gravity Assist" Masterclass
: One of the final additions to KSP 1 was the ability for docking ports to rotate. This allows you to align your space station modules perfectly after they've already connected. 4. Essential Career Milestones If you are looking for a "path" to follow in this version: Kerbal Space Program (v1.12.5.03190) [GOG]
: To reach the outer planets (Jool, Eeloo) with minimal fuel, launch toward Eve first. Passing behind Eve in its orbit will "pull" your craft, boosting your velocity and raising your apoapsis significantly for almost zero delta-V.
The most interesting physics quirk in KSP is that your engines are more effective when you are moving fast. : Always perform your major ejection burns at
: Replaces the static engine flames with beautiful, dynamic exhaust plumes.
: 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 The "Gravity Assist" Masterclass : One of the
: Attempt to visit three of Jool's moons in a single mission using gravity assists from Tylo and Laythe to move between them without burning fuel.
