How launch escape systems save astronauts

SpaceX’s Starship IFT4 launch:    • SpaceX's Starship IFT4  Can It Survi...  

Have you ever wondered how astronauts stay safe in the event of a failed launch? That’s where the launch escape system comes in. These come in three flavours, solid rocket motor, liquid rocket motor, or ejector seat. In this video, we’ll talk about how these work, and show you some live examples using the spaceflight simulator Reentry.

LES’s that we cover: Mercury, Apollo, Soyuz, Shenzou, SpaceX’s crew Dragon capsule, Boeing’s Starliner, Blue Origin’s New Shephard, Gemeni, and Vostok. We also cover why the space shuttle didn’t have an LES, and what it had instead.
