Propellant efficiency

Propellant efficiency refers to how effectively a rocket's fuel (propellant) produces desired movement. It measures how much useful thrust or speed is generated for a given amount of fuel used. Higher efficiency means the rocket can travel farther or carry more payload with less fuel, making missions more cost-effective and sustainable. Different propulsion systems have varying efficiencies depending on their design and purpose. Overall, propellant efficiency is a key factor in optimizing space travel, balancing fuel consumption with performance to achieve mission goals efficiently.
