Delta-V (academic journal)

Delta-V (ΔV) is a measure of the change in velocity a spacecraft can achieve, representing the effort needed to perform maneuvers like launching, orbit adjustments, or course corrections. Think of it as the "push" required to alter a vehicle’s motion in space. It’s a key concept in astronautics because it quantifies a spacecraft's capability to perform various mission tasks within fuel limitations. Higher Delta-V indicates greater maneuverability, while it depends on the spacecraft's propellant mass and engine efficiency, following the principles of rocket propulsion and the Tsiolkovsky rocket equation.
