Spacecraft Attitude Dynamics,The general motion of a perfectly rigid body is the superposition of translation and rotation. We talked about translation under the influence of a gravitational field and possible external perturbations in the previous chapters. Now we want to have a look at the rotational behavior of a body.

A chemical propellant, therefore, serves two different purposes at the same time: it is a provider of mass for the required mass flow rate and a provider of energy to accelerate itself to ejection velocity.

The difference between the two is that reentry is powerless and the initial conditions of both mission phases are drastically different.
