2.1 Role of Brakes in the Space Launch System (SLS)

The SLS rocket, designed to be NASA’s most powerful rocket, incorporates advanced braking systems to manage different stages of the launch:

• First Stage Separation: The SLS rocket consists of multiple stages, with the first stage providing the initial thrust. After the first stage burns out, braking systems ensure a safe separation from the remaining stages.
• Solid Rocket Boosters: The SLS uses solid rocket boosters, which have their own braking mechanisms to control their separation from the core stage.
• Stage Separation and Fairing Jettison: The rocket needs to ensure smooth separation of stages and jettison of the fairing, which are critical for the efficient progression of the mission.

2.2 Safety and Reliability

The braking systems are designed to:

• Manage High Speeds: Handle the extreme speeds and forces experienced during launch and ascent.
• Ensure Safe Separation: Facilitate the safe separation of rocket stages and boosters, preventing collisions and ensuring that the remaining stages can continue their mission.
• Minimize Risks: Reduce the risk of malfunction or failure, which could jeopardize the mission and crew safety.
