Well, I’ve always asked myself why can’t we use some kind of train or catapult to help the rockets to save fuel or to go further. Can anyone explain me why?
In: Engineering
The mechanism would have to be absolutely massive and at best it would only save a little bit of fuel. Some sort of mechanism the size of the tallest skyscraper would probably only be able to accelerate the thing up to a hundred miles an hour or so without subjecting the rocket to too much inertial stress, and rockets get to that sort of speed after only a few seconds.
