It can be used to keep track of a rocket's physical characteristics (height, weight, center of gravity, etc.), what engines it can use, when it has been launched and what engines were used for that launch, and what repairs it may need. In addition, Rocket Tracker keeps a list of all engines used by any of your rockets and will list all of your rockets that can use a given engine.
