SpaceX recently made an exciting announcement regarding the main engine cutoff (MECO) during a test of its Super Heavy rocket. MECO signifies the moment when the rocket's 33 engines are shut down, a critical step in the launch process.
During the test, the Starship spacecraft also ignited its own engines while the Super Heavy engines were being shut down. This simultaneous operation led to the observation of a fascinating phenomenon known as 'hot staging.'
