Delta-V (ΔV)

Understand Delta-V (ΔV) needs for Kerbal Space Program missions, from Kerbin orbit to interplanetary transfers, using VAB readouts and external ΔV maps.

Delta-V (ΔV) is the change in velocity your rocket can achieve, essentially its 'fuel budget'. It's the most critical metric for determining how far your rocket can go. Each celestial body and maneuver (e.g., Kerbin orbit, Mun transfer, Mun landing) requires a specific amount of ΔV.

Use the ΔV readouts in the VAB/SPH to plan your missions. Consult ΔV maps (available online) to understand the requirements for reaching different destinations. Always aim for a little extra ΔV than strictly necessary, as real-world piloting isn't always perfectly efficient.
