High-Isp propulsion

High-specific impulse (Isp) propulsion refers to rocket engines that are highly efficient at converting propellant into thrust. The "specific impulse" measures how effectively a propulsion system uses fuel, with higher values indicating better efficiency. This means a rocket using high-Isp propulsion can achieve more thrust for each unit of fuel consumed, allowing it to travel farther or carry heavier payloads. This is particularly important for deep-space missions, where efficient use of limited fuel is crucial to achieving mission objectives and reducing costs. Common examples include ion thrusters and other advanced propulsion systems designed for specific space exploration tasks.
