If fire needs oxygen, how do rockets stay lit in space?

Answer 1

Take a look at [this rocket diagram](https://www.grc.nasa.gov/www/k-12/rocket/rockpart.html) on NASA’s website. The fuel tank typically contains liquid hydrogen, although other fuels are sometimes used, and the oxidizer tank contains liquid oxygen. You’ve probably seen pictures of NASA’S spacecraft with one massive rocket, and two smaller rockets fastened to each side. The massive rocket is designed similarly to the rocket in that diagram, but the smaller side rockets usually contain solid propellants that won’t produce thrust in space.
