A rocket carries it own oxygen. The Space Shuttle has two types of rockets, a solid fuel rocket and liquid fuel rockets. The two strap on rockets on the side are called SRB's or Solid Rocket Busters. The oxidizer is mixed into the solid propellant so that it will burn anywhere. The liquid rockets use fuel from inside the large tank that the shuttle sits on.
