Orbital Maneuvering,The most important maneuver in space is the one to change the orbit of a space vehicle. Because the initial and final orbits are subject to a central gravitational potential such a S/C will transit between two Keplerian orbits. This is true not only for planetary orbits but also for interplanetary flights with the Sun as the central body.作者: 感情 時(shí)間: 2025-3-26 06:01
