This is because they are easier to mantain as it does not require launches to get astronaughts up there to fix them. Also they are cheaper having to make a telescope usable in space takes time and money, it also requires a launch which is expensive as well. It is easier to view the results as you can view them directly form the telescopes, instead of them having to be sent from space down to earth using microwaves then you need an antana and other equipment to view it.

Which of the following is not an advantage the Hubble Space Telescope has over ground based telescopes?
It is closer to the stars
What is an advantage of using orbiting telescopes rather than ground based telescope?
There is no distortion from Earth's atmosphere.
Do astronomers use ground-based X-ray telescopes?
No they do not, or use gamma ray telescopes either. Not ground based.
What technology has been used to investigate Saturn?
Ground telescopes and orbital satellite telescopes.
What do astronomers use to look at planets?
Their eyes, ground-based telescopes, space telescopes.
What advantage do reflecting telescopes hAve over refracting telescopes?
One advantage of reflecting telescopes is that the mirrors can be very big. Large mirrors allow reflecting telescopes to gather more light than refracting telescopes do. Another advantage is that curved mirrors are polished on their curved side, which prevents light from entering the glass. Thus any flaws in the glass do not affect the light. A third advantage is that mirrors can focus all colors of light to the same focal point. Therefore, reflecting telescopes allow all colors of light from an object to be seen in focus at the same time.
What is an advantage of using orbiting telescopes than ground based telescopes?
They are not affected by the diffraction ("twinkling") caused by light travelling through the earth's atmosphere. Also, orbiting telescopes are not affected by atmospheric dust pollution nor light pollution.
What are the major types of optical telescopes?
Ground-based telescopes, and space telescopes. Or: refracting telescopes (main collector is a lens), and reflecting telescopes (main collector is a mirror). Or: Home telescopes (small ones), and professional ones (larger and more expensive).
Why do astronomers currently prefer orbiting telescopes over earth based telescopes?
Orbiting telescopes are located in the sky, where it is not affected by the turbulence of the atmosphere, while ground-based telescopes are located on the ground, where the atmospheric turbulence (the moving of air) is greater. This is also the reason that some telescopes are built on mountains where the atmosphere is thinner and turbulence is smaller.
Which is the sugnificant advantage of space telescopes comapred with telescopes licated on Earth?
Light enters space telescope without distortion from Earth's atmosphere
Why is it advantageous to have telescopes in space?
The main advantage is that it avoids distortion from Earth's atmosphere.
Why are x-ray telescopes and gamma - ray telescopes in space?
The earth's atmosphere doesn't let these rays reach the ground, so the telescopes are placed in orbit where they can receive the rays.
