Energy efficiency in space travel

Energy efficiency in space travel refers to using the least amount of fuel and resources necessary to achieve a mission's objectives while minimizing waste. It involves optimizing rocket propulsion, spacecraft design, and trajectory planning to reduce fuel consumption and increase operational effectiveness. By improving energy efficiency, space missions can extend their range, reduce costs, and maximize the scientific or exploratory output for the resources invested. This approach is crucial because launching and carrying fuel into space is expensive and limited, so making the most of available energy ensures safer, more sustainable, and more successful missions.
