Inertia. Newton's first law.
It either keeps it still on the ground or stable as it's moving, but I'm not Stephen Hawking...
As a rocket enters space, there is no opposing force to slow it down, so as it continues, it loses no momentum. THere is no outside force to act on it to slow so it can save fuel.

Inertia can be thought of figuratively as a mass's laziness. Think of when you are lazy. When you're lazy and doing nothing, you tend to stay that way. You continue to do nothing unless prodded to do something. (Perversely, in people, laziness causes idleness and idleness causes laziness.) Well, masses are the same way. When they're inert -- meaning not moving -- they tend to stay that way because of their laziness. That laziness is called inertia. When a huge rocket laden with tons of fuel is sitting on the launch pad, it has tremendous inertia because it is massive. To get that thing moving takes a huge amount of power. But once it's moving, the rocket's inertia, instead of being a handicap, becomes an asset, because any mass, once it's moving, likes to stay moving. Moreover, as the rocket burns off fuel, its mass decreases, so less energy is required to propel it.
we have to connect mini rockets to the main rocket which will transfer material
The momentum (given by the property of inertia) makes whatever was propelled by the rocket continue at the same velocity as before, until another force (like running into a planet) affects that object.
