The shuttle does not fire it's engines in space, it only fires orbit adjusters.
The space shuttle is able to fire its engines in space because it takes the needed oxygen with it.
The solid rocket boosters used by the space shuttle separate and fall away once they are burnt out, so there is no risk of them catching the shuttle on fire. Additionally, the boosters are designed to burn cleanly without producing excess flames or residue that could harm the shuttle.

Easy the shuttle that is currently in orbit is going about 25,405 feet per second (17,322 statute miles per hour). In order to get back to Earth the shuttle will fire a In order to return to earth, the shuttle fires its Orbital Manuevering Engines (OMS) in the direction opposite to its orbit, also known as a "de-orbit burn" . It only slows down by about 200 m.p.h. in order to begin "falling" back to earth.
Fire needs oxygen in order to burn, and there is no oxygen in space, so rockets must take oxygen with them.
The space shuttle was developed because the weight of satellites or payload required huge rockets. The shuttle main claim to fame is that it was also reusable. The only thing that is not recovered after launch is the liquid hydrogen fuel tank. The solid rockets on either side of the hydrogen tank burn out, separate, then fall to Earth. After the solid rocket separation the shuttles main engines continue to fire to get into orbit. When the fuel tank is separated it burns up in the atmosphere.
Columbia heated up and broke apart while entering the atmosphere.
A space shuttle overcomes Earth's gravity by using powerful rocket boosters and engines to generate enough thrust to lift the spacecraft off the ground. Once in space, the shuttle relies on continuous acceleration to stay in orbit rather than fighting against gravity.
It is not possible to burn a fire in outer space because fire requires oxygen to burn, and in the vacuum of space where there is no oxygen, there can be no combustion. On space missions, fires are not ignited but rather prevented through strict safety protocols and the use of non-flammable materials.
The Space Shuttle has enough residual fuel on board to fire it's main engines just long enoughto orient to the correct position and move out of orbit. From that point on, gravity takes over, and the shuttle glides all the way to the ground - one it leaves orbit, no engine power is used at all.
Retro burners. Retro meaning opposite or backward. After burner is forward or ahead of you. They fire the thrusters to slow down or even stop. But really, who knows what stop is if we have no real reference? But if your talking about Earth as the reference, my statement is otherwise correct.
The entire Shuttle countdown is choreographered and pre-planned. During the last 10 seconds the Space Shuttle's main engines fire, check themselves, the entire stack swings with the thrust, and the boosters ignite.
