We just learned about Gimbaled Thrust.
After a rocket is launched, it needs to be guided to make sure that it goes to the right place, whether that's outer space or just up into the atmosphere.
This is called Guidance, navigation and control, sometimes shortened to just GNC.
GNC is the science of how to control a rocket after it's been launched up into the air.
