Fuel Efficiency
Fuel efficiency is the measure of how much fuel is consumed by a spacecraft or rocket to perform a specific task. It is a critical factor in space and astronautical engineering as it directly affects the cost, range, and performance of the spacecraft. Fuel efficiency is achieved by optimizing the design of the spacecraft, including the propulsion system, aerodynamics, and weight. The use of lightweight materials, such as composites, and advanced propulsion systems, such as ion engines, can significantly improve fuel efficiency. In addition, mission planning and trajectory optimization can also contribute to fuel efficiency by minimizing the amount of fuel required to reach a destination or perform a maneuver.
