Electric propulsion systems
Electric propulsion systems, such as ion and Hall thrusters, use electric power to accelerate propellant to high speeds, resulting in greater efficiency and higher velocities compared to traditional chemical propulsion systems.
Nuclear thermal propulsion
Nuclear thermal propulsion utilizes nuclear reactors to heat propellant, increasing exhaust velocity and providing higher thrust, which can significantly reduce travel time for interplanetary missions.
Advanced chemical propulsion
Advancements in chemical propulsion, such as the development of high-performance rocket engines and new propellant combinations, are also contributing to faster and more efficient interplanetary travel by increasing thrust and specific impulse.
