Orbits in the Two-Body System
摘要
AfterOptimization problemascent ascent, we are now in outer space. How does a spacecraft move under the influence of the gravitational forces of the Sun, planets, and moons? This is the question we will deal with in this chapter, and we are pursuing general answers to it. Let us be realistic: The details of motions are usually very complicated and can be determined sufficiently accurately only numerically on a computer.
