ELI5, How do rockets go straight up into space?

490 views

Like Jeff Bezo’s… Uhh… Rocket… Don’t rockets need “fins” or “wings” to help stabilize or something?

Big rockets generally are able to steer by angling their engines. Also, if you’re going to actually orbit the planet, you don’t fly straight up, you pitch over sideways in what’s called a gravity turn, because getting into space is the easy part, to actually get into orbit you need to go sideways fast enough to miss the planet on the way back down, which takes much more energy.
