- The rocket could hover at a fixed altitude. The potential energy of the rocket body will be decreasing as the altitude remains constant and the mass is decreasing. There would be no kinetic energy associated with the rocket body itself.
- The rocket could be climbing at a constant rate as it coasts upward. The kinetic energy of the rocket body would be decreasing as the mass decreased and the velocity was constant. The potential energy could either increase or decrease depending on whether the altitude increased faster than the mass decreased.
- The rocket could be falling at a constant rate as it coasts downward. The kinetic energy of the rocket body would be decreasing as the mass decreased and the velocity was constant. The potential energy would be decreasing as both the altitude and mass decreased.

I would appreciate any thoughts on this question.
