ffuturesI think someone told me that (ignoring travel times) it actually takes less energy to travel from Earth to Mars than between Jupiter's moons. Can anyone point me at a source for this? And for energy requirements for other interplanetary journeys? Preferably something that I can use without breaking copyright?
