Explore further. Try modifying the Environment and Advanced settings (just click on them). Some suggested extensions:
- What about seriously heavy planets, like Jupiter?
- The exhaust velocity is how fast the spent fuel comes out of the back of the rocket. Why does this figure matter? What kind of exhaust velocity would you need in order to escape Earth gravity with a single stage design?
- The mass ratio is the proportion of each propulsion stage's mass that consists of fuel. Why does this figure matter? What kind of mass ratio would you need in order to escape Earth gravity with a single stage design?
