Why is Newton's Theory of Gravity used for space missions instead of Einstein's General Theory of Relativity?

Newton's laws are good at describing motion in a zero gravitiy invironment where as Einstien's theories would be more useful if you were travelling near the speed of light.

Can gravity exert its force on space and time?
Before you depend on this "General Relativity", you should check what it depend on. It relativises its reference frames, arguments, concepts, imaginations, assumptions in a big and complicated circle --- its base is relative. If you want to lean on something based on that shaky ground, it's your choice.
How did Arthur Eddington prove Albert Einstein's theory of relativity?
Well, to clarify, Eddington proved one aspect of Einstein's Theory of General Relativity. Einstein predicted that light would actually be gravitationally "bent" when passing by a large body with powerful gravity. The only way to test this from earth was to observe a total eclipse with information beforehand of what stars would be visible near the sun at totality. If the light from those stars appeared "nearer" to the sun than it should have been during totality, it was the sun's gravity that was "bending" the light of those stars. Eddington's observations were accurate during the total eclipse of 1919, and it was accepted that he had proved that aspect of General Relativity. But there are many other aspects of General Relativity. Eddington proved oneof them.
What keeps the sun from blowing up answer?
Gravitational pull of sun makes the planets orbit it.Also, centripetal force acts in opposite direction of centrifugal force(force that pulls an object towards the centre of a circle)to keep planets in their orbits around the sun According to General Relativity the sun warps spacetime with its gravity. The earth follows a locally straight world line in that warped spacetime, but globally that world line is a helix centered on the sun's world line. There is no gravitational pull or centrifugal/centripetal force in relativity.
Does mass change on other planets due to gravity?
No. Except for insignificant effects related to Special Relativity, the mass remains constant. The weight, on the other hand, changes. Weight is calcualted as: weight = mass x gravity Where "gravity" is the acceleration due to gravity.
Who founded the earth gravity?
No one 'founded' gravity. On earth or elsewhere. Gravity is a physical attribute of the universe in general. The first to explain the relationship of gravity to the universe in cogent and mathematically provable ways was Sir Isaac Newton.
When Einsteins theory of gravity general relativity gained acceptance it demonstrated that Newtons theory had been?
Incomplete
What is the relation between Relativity Gravity and the Planets?
Relativity is a theory of gravity, and gravity governs the motion of planets. This is your answer in a nutshell. If you want a detailed answer, then I suggest you start studying general theory.
From what scientific starting point did Einstein deduce his Theory of General Relativity?
Einstein deduced his Theory of General Relativity from trying to understand gravity, it was essentially his theory of how gravity worked and why it functioned that way
What did Einstein have to do with gravity?
In his General Theory of Relativity, he provides some interesting insight into the nature of gravity.
What Galaxies that requires the use of general relativity?
Every galaxy. General relativity is the most general theory of gravity we have to date. Newtonian gravity works to describe many things but it falls apart under certain situations.
What is Einstein's theory of gravity called?
The theory that Einstein developed which pertains to gravity is called general relativity.
Is the force of gravity or E and M subject to relativity?
Yes. Everything is subject to relativity. We know that electormagnetism (EM) is subject to relativity because we see light from distant stars and galaxies bent by the gravity of intervening objects (see http://en.wikipedia.org/wiki/Gravitational_lens). Gravity is subject to relativity because it is an essential element of General Relativity. GR says that gravity is the curvature of spacetime.
Is there anything called Gravitational Push?
yes. there is no such thing as the gravitational pull however. look up Einsteins theory of special relativity. the bend of space is what gravity really is.
Why is Einstein's theory of general relativity so important?
For it basically means that he has explained how gravity works
What is the difference between quantum and relativity?
Relativity has two parts: General relativity and special relativity, general relativity describes gravity as a geometric property of spacetime and special relativity is the physical theory of measurement in inertial frames of reference. Now quantum mechanics, in it's wave formulation, deals with describing things on the atomic scale as a wavefunction.
Does gravity only effect mass?
Yes, basically. Although according to the General Theory of Relativity, it will also distort space and time. The effects are not easily noticed at the relatively modest gravity of Earth.Yes, basically. Although according to the General Theory of Relativity, it will also distort space and time.

Is gravity a attraction or repulsion?
In general gravity is an attractive force. There are some subtleties in general relativity however that might give the appearance of a repulsive force, but for almost all intents and purposes gravity is an attractive force.
