This answer is predicated on two assumptions - 1) we can neglect air resistance (stated in the question) on both the upward and downward paths, and 2) the rockets are in free-fall (not propelled) after launch. I wrote out a thorough explanation to this beefy question, but it was too long to put directly into this reply. The essence of Newton's theory of gravitation is that the force between two bodies is proportional to the product of their masses and the inverse square of their separation and that the force depends on nothing else.
