Space Exploration Vehicles: Innovations in Propulsion and Autonomous Navigation

Future deep space missions use technology that combines propulsion system advancements with autonomous navigation. Chemical ‎propulsion systems can’t handle excessive fuel consumption and tasks that go beyond the short term. Ion propulsion and nuclear propulsion ‎deliver better specific impulse and fuel efficiency for near-fast interplanetary flight. The ion propulsion on NASA’s Dawn spacecraft ‎extends mission duration while using less fuel than conventional systems, but nuclear power generates enough power to explore ‎interplanetary space. Modern automated navigation is a critical system to minimize human intervention when operating spacecraft over long ‎distances. Extended missions have trouble keeping real-time Earth communication links due to mission distance, which introduces signal ‎delay problems. When spacecraft integrate inertial navigation with star trackers and artificial intelligence, their computers can do real-time ‎tasks like trajectory changes and mission changes, and space obstacle avoidance‎.
