Delta V Calculator
Calculate the change in velocity required for orbital maneuvers
📖 Delta V
Delta V (Δv) is the change in velocity required for a spacecraft to perform orbital maneuvers. It's calculated using the Tsiolkovsky rocket equation and determines fuel requirements.

💡 Tips & Information
- Delta V is measured in meters per second (m/s)
- Formula: Δv = ve × ln(m₀/mf) (Tsiolkovsky rocket equation)
- Earth to LEO requires ~9,400 m/s Δv
- Earth to Moon requires ~15,900 m/s total Δv
- Higher exhaust velocity and mass ratio = more delta V capability
