Rockets push against themselves they don't push against the air. That how they get there momentum. But I'll leave it up to these three guys. They explain it more in detail and its easy to understand.
Rockets don't get thrust by pushing against the air. Rockets get thrust by pushing against the rocket on one side and pushing against nothing on the other side of an explosion.
The rocket ejects a mass of burned fuel to produce a force. The force produced is proportional to the amount the mass of the combustion products (the exhaust) was accelerated. This follows from F=ma (Force = mass x acceleration)
So, the more you accelerate the exhaust, the more force is applied to the rocket.
Imagine you are floating in space. If you take off a shoe and throw it away from you really fast, you will move in the opposite direction from your shoe. You can even do this without going into space if you are standing on a very low friction surface like ice.
Also, the shape of the rocket exhaust nozzle is made or 'tuned' in such a way that it captures the expanding gasses escaping the combustion chamber of the rocket engine as efficiently as possible.

How do rockets move in space?
rockets move with the control
What makes rockets move so fast?
rockets are filled with fuel called thrust and the engine mixes this in and that sets it too go really fast
How did the space shuttle try to move in space?
The shuttle moved by the use of thruster rockets.
How do spacecraft move?
They use big fuel powered rockets that generate a huge amount of thrust to propel them.
Where can rockets go?
rockets can go anywhere.space is where rockets can go
How does a satellites move in space when its vacuum?
well space is like a vacuum you cant escape it and sound wave do not travel in space but space isn't literally a vacuum so they move by rockets and the gravity of earth
How do rockets move in space?
rockets move with the control
Can rockets be launched in vacuum?
Yes. Rockets have both a fuel and an oxidizing agent, so they don't need air.
Are rockets and jet engines the same?
No. Jet engines draw oxygen from the atmosphere to mix and burn with jet fuel, and cannot function in a vacuum. Rockets carry their own oxygen, and can travel in the vacuum of space.
Energy that can move through a vacuum?
The entire electromagnetic spectrum can move through a vacuum.
Why do the particles move faster in a vacuum?
Particles do not move faster in a vacuum. Particles move faster when the temperature increases.
Why electron travel through the vacuum and not travel through the air?
how electron move in vacuum and not move in air
Can sound waves move through space?
space is a vacuum, and sound can't move through a vacuum.
How rockets help us explore space?
Rockets provide force that can propel ships forward, even in the near vacuum conditions of space. Propellers can provide force only in a substantial atmosphere.
Do sound waves move in a vacuum?
No.
Do electromagnetic waves move in a vacuum?
yes, at 'c' the speed of light in a vacuum.
How many ways can a rocket move?
Rockets move 4 different ways. Left, Right, Up, and Down
