What is the first stage of a rocket called?

Why do rockets tilt after takeoff?

Rockets have to tilt to the side as they travel into the sky in order to reach orbit, or a circular path of motion around the Earth. This steering technique is known as a gravity turn, which uses Earth’s gravity to help conserve rocket fuel and minimize stress and strain on the spacecraft.

Why do rockets turn east?

So if we launch the rocket toward the east, it will get another big boost from Earth’s rotational motion. Now, we launch eastward. Then, when the spacecraft is headed in the same direction as Earth’s orbital motion around the sun, the rocket gives it a final boost out of Earth orbit and on its way.

Do Rockets come back to earth?
