Best answer:
Answer by Bill
its exhuast, it cant be re collected, at least not 100 percent
a rocket engine runs on liquid oxygen, and hydrogen gas, when the burn its like burning gasoline but stronger and it has no carbon. its an external combustion engine though, that means all the reaction takes place outside the engine, or that the energy is vented straight out of the engine
so all exhuast is just left, they could use some type of collector i suppose to reclaim the water, but it wouldnt be efficent
