RSS ∆v Maps - KSP-RO/RP-1 GitHub Wiki
The following page collects a number of high-quality ∆v maps of our solar system.
Be aware that these numbers are generalized, and specific values will vary based upon ascent parameters, vehicle properties, and mission design. In particular when playing with more accurate n-body gravitation (such as that offered by the excellent Principia mod), ∆v values may vary depending upon inclination changes, orbital precession, and certain types of low-energy and ballistic capture trajectories.
Nevertheless, the following resources are excellent guides for initial mission planning.
