The main advantage would be the absence of an atmosphere. Any telescope on earth can only "see" electromagnetic (light) waves after they have travelled through the atmosphere, losing some of their directional integrity, which distorts the image seen in earth bound telescopes. Some light waves never make it to the telescope at all.
With a terrestrial (ground-based) telescope, maintenance involves two technicians with a pickup truck and a toolchest.
For orbiting telescopes, "maintenance" - to the extent that it is possible AT ALL - involves a Space Shuttle mission, two years of preparation and training, and 200 million dollars in expenses. The Hubble is in a low-Earth orbit, specifically planned to be maintainable by the Shuttle. (The original plan was that a Shuttle would bring the Hubble back to Earth at the end of its useful life, to be placed in the Smithsonian Museum. With the retirement of the Shuttle fleet, this will no longer be possible.) Other space telescopes, like the Spitzer, are in higher orbits beyond the range of the Shuttle.
Additional disadvantages are size and weight restrictions on the size of a space telescope. Ground-based telescopes can be quite massive, while a space telescope is constrained by the maximum mass that can be lifted by our heaviest booster rockets.
You can see everything in different types of the electromagnetic spectrum, and see A WHOLE LOT FARTHER than Earth instruments
If you have a telescope in space, you avoid the effect of Earth's atmosphere on your observations.
Improved seeing due to zero atmospheric distortion.
A radio telescope.
The Hubble Space Telescope, along with most man-made satellites, is in a low earth orbit. It remains 559 km from the earth. This is much closer than the moon, which orbits at an average distance of 384,392 km. It would be very difficult to have a man made satellite orbit further away from the earth than the moon without the moon interfering in its orbit.
NASA's most famous telescope is probably the Hubble Telescope that orbits the earth.
Yes, mirrors do work in outer space! That is because light also travels in space just like on Earth.
More than you can see from earth. The earth's atmosphere (and light-pollution) diminish what one can see with a telescope on the surface of the earth. From space the telescope can see much further in both space and time - the light from something we can see in space left that object many years ago. The light from the sun takes about eight or nine minutes to get to earth. The light from the nearest star takes about four years to get here. The farther back you can see across space, the farther back in time you are looking. If you are a child, then i would recommend the national geographic 50mm telescope. you can get these from argos. They are very good, for you can view the moons craters, jupiters moons, saturns rings, mercury, and much more, they can also be used to see things in the same room as you, but can still show very high quality images

Otherwise it would fall towards the earth due to gravitational attraction.
You can't see "space". You can see objects in space, but space itself is not visible.If you did wish to observe objects in space, a telescope would help you to do so.

the hubble space telescope cost 1.5 million dollars

Yes. You are able to see Jupiter with a telescope from Earth at certain points in the year.
uh...that would be telescope or dope.
Not yet. The Hubble Space Telescope is still in space, still operational. In fact, it received a substantial upgrade just last spring, with new gyroscopes, new sensors and a new communications array. But the main telescope cannot be upgraded without being entirely rebuilt, which cannot be done in space. The original plan was that the Hubble Space Telescope would be captured in orbit by the Space Shuttle, returned to Earth, and rebuilt. Later, it would be re-launched. But because the Space Shuttle fleet itself is scheduled to be retired in the next few years, this plan has been abandoned. The HST is tentatively scheduled to be de-orbited and crashed into the ocean in about 7 more years. With luck, there will be an even more powerful space telescope to replace it, but this is not yet firmly scheduled.
