Delta-V (literature)

Delta-V (Δv) is a measure of the change in velocity a spacecraft can achieve using its onboard propulsion system. It represents the ability to perform maneuvers such as altering trajectory, orbit, or heading. In essence, delta-V quantifies the "flying power" of a rocket or spacecraft, indicating how much it can accelerate or decelerate. This concept is fundamental in mission planning, as it helps determine the amount of fuel and propulsion needed to reach a destination or execute specific maneuvers efficiently. Think of delta-V as the "change in speed" capability essential for space navigation.
