https://doi.org/10.1007/978-3-642-92094-3In Chap.?., we have looked at two point masses that were moving under their mutual gravitational influence. Formally speaking we were dealing with two bodies each with six degrees of freedom (three position vector components and three velocity vector components).

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.

Planetary Entry,After a spaceflight, the planetary entry (a.k.a. reentry for entry into Earth’s atmosphere) of a spacecraft is subject to the same aerodynamic and physical laws and equations (see Eqs.?(6.3.6) and (6.3.7)) as ascent. One might therefore infer that the circumstances of both situations are the same.
