# Is it correct that rocket reuse is much more difficult for the upper stage than the lower stage?

If this is true, it means that (assuming a two-stage rocket), the lower stage is, at least in theory, easier to reuse, since it has less deceleration to do, and so its heat shielding can be lighter and less sophisticated; and if that is true, then it follows that the lower stage should be simpler (and therefore easier and cheaper) to reuse than the upper stage... Am I correct? Is the sub-orbital lower stage really so much simpler to reuse than the orbital upper stage? Or, am I, due to some combination of poor sources and poor inferences, mistaken? ## Answers ### A
