Experimental evidence, from spacecraft behaviour, has shown that the concept of an absolutely rigid body, which has served us so well in the past, apparently no longer suffices to provide for the theoretical treatment of all problems settings in solid mechanics. The purpose of the present paper is to demonstrate that the introduction of a dissipative rigid as a fundamental concept into theoretical mechanics has become a necessity. Using data from a disabled spacecraft, the paper begins by describing the attitude decay of a gyroscope in detail, using the concept of a dissipative rigid, and its dissipation power, for the theoretical treatment. Against this background, the case for the dissipative rigid body is made in general terms. Each relation bears re‐deriving, and those affected are presented in their new form. While the concept of a dissipative rigid body is quite general, it can be shown to play a role in gyrodynamics (including impact studies, where it is well established only, a conclusion that explains why its general introduction had to wait until after the advent of the space age.
