* On viewing the space you don't have any obstacles in between.
* In land you cannot have a open space for more than few kilometer.
* The shape of the earth is round and after a certain distance the objects starts hiding. For example, stand in a shore, watch a ship moving away from you, after certain distance you can notice the height of the ship reducing down and eventually it will get out of sight from you, even if you view thru binoculour or telescope from a land level.
So, you need a height to see even in a open space and in case of land with obstacles like buildings, trees, you have to go to more heights.

As the name suggests space telescopes are meant for observation in the space. To use the same on land will defeat its purpose. Hence we use land telescopes to see ground level things which is in far distance.

Because the planet is round! You can only see in straight lines, there is no bending around corners.
Take a look at a globe once and then place a pencil or something on it. How far can you see without moving the pencil? 20-30 miles?

They use binoculars which are like telescopes. And as already given in another answer, the curvature of earth doesn't allow you to see too far. So, telescopes and cameras are fitted in satellites so that we can see what is happening far away.

the curvature of the earth, you can only see about 25 miles into the horizon....if the earth were flat then maybe using the space telescope would be a cool idea

It's because space is covered by atmospheres only which are invisible, while land is a visible thing which a telescope cannot see anything under it..........

definite. in certainty, if the telescope is severe adequate, you could objective particularly downwards to view the horizon. of direction, there could be so plenty extra atmospheric distortion at this manner of low attitude.

because of the angle it covers.on earth ir reduces to about 1/3
