"SpaceX Releases Slow-Motion Video of Raptor Rocket Engine Shutdown"
SpaceX has released a slow-motion video showing a Raptor vacuum engine shutting down, revealing visible rings in the exhaust due to flow separation at sea level and low chamber pressures. The Raptor engines power the Starship spacecraft, with six engines for landing and 33 for the Super Heavy rocket. These engines are more powerful than those used by the Falcon 9 rocket and are crucial for SpaceX's ambitious missions, including crewed flights to the moon and potentially Mars in the 2030s.
