The differences between an aircraft and a spacecraft?
Spacecraft lack wings & their engines don't require air to function.
What are thrusters?
Thrusters are small engines (propulsive devices) used to move a spacecraft small amounts. They are used to adjust the position of a spacecraft to keep it in the same orbit or on the same path, and to keep it pointing in a desired direction. The can also be used to accelerate space probes slowly over long periods.
How is a spacecraft launched?
There are about four forces that act on a lifting off spacecraft . The four forces are the thrust force, the weight of the spacecraft, the drag and the lift force.
What is the difference in propulsion between an airplane a spacecraft?
Aircraft are driven by air breathing engines whether combustion or jet. All spacecraft must be propelled by rocket or something else that needs no air to perform
What force causes the spacecraft to orbit the moon?
gravity pulls space craft towards it. It's engines make it go round, the engines have to push the space craft away from the moon to stop it being pulled down to the surface
In outer space can travel at a constant speed and in specific direction without slowing down occur even when the engines are turned off why?
Yes. No air friction.

Why are rocket engines used to launch a spacecraft?
To give the space craft a boost
Has anyone attempted to change the direction of a rocket?
Nasa does it all the time- there are maneuvering jets, steering engines, etc- used for angular corrections ( bear in mind in space there is no atmosphere or wind resistance) Spacecraft- once underway run on momentum a good deal- engines shut down... economical.
What happens if a spacecraft is orbiting the earth and wants to go faster so turns the engines on?
That depends upon the direction in which it is facing when it turns its engine on. If it faces the direction in which it is already moving, the added speed will cause it to move to a higher orbit. If it faces against the direction in which it is moving to slow down, it will move to a lower orbit (or re-enter the atmosphere). If it faces any other direction, its orbit will change in various other ways.
Are the exhaust gases from vehicles ionised?
No. not earthly vehicles. Some spacecraft have ion engines (at least they have been proposed).
What kind of engines are in a plane?
jet engines, turbojet engines, turbo-prop engines, four-stroke piston driven engines... Can you be more specific?
When will a mass of a spaecraft change?
Since the spacecraft's fuel supply is mass, then the mass will decrease whenever the engines are started. If the spacecraft collides with space dust or a rock, then the total mass will increase slightly. Of course, if it's a big rock, the spacecraft may be destroyed in the collision.
