Delta V Calculator - Nexus Aurora

How far can we go?

When moving around the solar system Delta V (ΔV) is the most used metric to determine how much fuel we need to put a payload into an orbit or land at a destination.

This calculator uses the Tsiolkovsky rocket equation to determine ΔV. All ΔV values are based on Hohmann transfer orbits.

Note: All values are estimates.

Payload Mass

{{formData.twoStage ? "Second Stage " : ""}}Rocket Mass

The dry mass of the rocket

{{formData.twoStage ? "Second Stage " : ""}}Fuel Mass

{{formData.twoStage ? "Second Stage " : ""}}Specific Impulse (I_sp)

{{ formData.exhaustVelocity | addCommas }} m/s Exhaust Velocity (V_e)

Example Rocket Engine

Specific Impulse values are estimates

Two Stage Rocket?

First Stage Dry Mass

First Stage Fuel Mass

Sea Level Specific Impulse

{{ formData.seaLevelVelocity | addCommas }} m/s Exhaust Velocity (V_e)

Refill second stage in orbit?

Is the rocket reusable?

Results

First Stage ΔV	{{ firstStageDeltaV \| addCommas }} m/s
Second Stage ΔV	{{ secondStageDeltaV \| addCommas }} m/s
Total ΔV	{{ totalDeltaV \| addCommas }} m/s
