Presumably the most important force on an accelerating space shuttle is the force of the rocket engines (thrusters). Certainly other forces are present, including gravity and air friction.
The amount of gravitational force acting on the space shuttle in orbit is still significant, approximately 90% of the force experienced on the surface of the Earth. This force is what keeps the shuttle and astronauts in orbit around the Earth, counteracting the centripetal force that tries to pull them away.
When a shuttle reaches outer space it can turn off its thrusters because the law of inertia states that an object in motion can stay at motion until a force acts upon it. And it can just fly without wasting gas/fuel.
Certainly it appears that gravity does so.
As the space shuttle re-enters Earth's atmosphere, it uses its shape and heat shield to create aerodynamic lift, which counteracts the force of gravity pulling it down. It also utilizes thrusters and control surfaces to maintain a controlled descent trajectory. Additionally, the shuttle's velocity and angle of approach are carefully calculated to reduce the effects of gravity during re-entry.
If you take newton's second law this sounds very easy. "An object in motion stays in motion until an outside force acts upon it" Since ther are now outside forces in a vacuum besides the space shuttle's engines, once you get the ship going, it keeps going until you slow it down yourself. Since there are no air molecules to push against, you cannon use turbines or blades, you have to throw material you have away from you to change direction or speed, this is generally compressed gas or ignited rocket fuel, but in sketchy moments, an astronaut has been known to throw tools away so it pushes them to where they need to be.

When a force acts on an object, you will observe the object either speeding up, slowing down, or changing direction depending on the direction and magnitude of the force. This change in motion is a result of the acceleration caused by the force applied to the object.
The force that acts through space is gravity. It is a fundamental force of nature that causes objects with mass to attract each other.

Yes, a force such as gravity acts on a projectile, influencing its trajectory and motion. The force of gravity accelerates the projectile downward, affecting its path and causing it to follow a curved trajectory.
Certainly it appears that gravity does so.
When a nonzero net force acts on an object, the object will accelerate in the direction of the force. The acceleration of the object is directly proportional to the net force applied and inversely proportional to the mass of the object, as described by Newton's second law of motion (F = ma).
When an unbalanced force acts on an object, the weight of the object decreases.
Then one force is overcoming another force, and the object moves.
