At liftoff, the core stage and twin solid rocket boosters fire to propel the rocket off the launch pad send it into orbit. Once in orbit, the upper stage provides the in-space propulsion to set the spacecraft on a precise trajectory.
What are the three stages of a rocket launch?
Stages of a Rocket Launch
- Primary Stage. The primary stage of a rocket is the first rocket engine to engage, providing the initial thrust to send the rocket skyward.
- Secondary Stage. After the primary stage has fallen away, the next rocket engine engages to continue the rocket on its trajectory.
- Payload.
What happens to Stage 2 of the rocket?
Stage II is restartable, and fires twice. The first burn occurs during the final portion of the boost phase and is used to insert the second and third stage spacecraft stack into a low Earth orbit. The second stage is programmed to shut itself off once the rocket and spacecraft are in orbit around Earth.
