Rocket Equation Calculator — Frequently Asked Questions
Q1 What is a typical mass ratio for an orbital rocket stage? ▾
High-performance stages achieve mass ratios of 10 to 20, meaning 90%–95% of initial launch mass is propellant.
Q2 Why are multi-stage rockets necessary for orbit? ▾
Staging discards empty propellant tanks and structures, resetting the mass ratio and multiplying achievable Δv.
