Every action has an equal and opposite reaction. Thus when the rocket is lit and the exhaust is ejected from the back, the shuttle moves forward at a
rate equal to the rate at which exhaust exits the space craft. Don't quote me on this because I am not entirely sure.
Every action has an equal and opposite reaction. Think of the diet coke and mentos thing.
When the chemical reaction starts, it causes the soda to expand rapidly. It cannot go anywhere but out the hole, so it does. However, it expands so
quickly that it comes out with force, and with every action(the expansion and launching of the soda) comes an equal and opposite reaction(the bottle
gains thrust). This is essentially what they use to get the rocket in space, and it would work with or without an atmosphere. To maneuver in space,
they have little thrusters built into the side(or wherever they need it) that effectively does the same thing, allowing the rocket to push off of the
chemical booster to maneuver.
