The best known Hubble repair mission was to install a fix to some flawed optics aboard the telescope. Other missions have been to replace other aging hardware and install more capable equipment for more advanced research.
If they need to repair a telescope in space, they send up a manned space shuttle to manually repair it.
You don't actually need a telescope to look at "Space". Just look up on a clear night sky and hey presto! You can see the Universe before your very eyes! But if you want to look at planets or you want a close up picture of the moon I suggest you use a quality telescope.
You can't buy observing time on the Hubble. It's given free of charge. all you have to do is write up a proposal that describes what you intend to do with it, and how that will contribute to the investigation of any hot topic in Astronomy, Cosmololgy, Relativity, or Planetary formation that the professionals are all working on. If the organization that controls access to the Hubble feels that your work can make a useful contribution to modern scientific research, they'll give you the time on the Hubble that you'll need for it.
First, they have a major advantage, and that is that they have a much clearer image, due to the lack of atmosphere.The disadvantages are mainly related to the high cost of putting the telescope up into space, and maintaining it (you can't just walk over to repair something). For this reason, other alternatives are also used, or considered, such as telescopes on Earth that compensate the atmosphere with a larger size, or advanced adaptive optics, or even telescopes carried on airplanes at a high altitude!
Telescopes that work with light and radio waves can work from Earth´s surface. Any other types of electromagnetic waves will hardly reach Earth's surface, so to use those (e.g., X-rays, infrared, and others), telescopes have to be taken to outer space.

In space there is no atmosphere and therefore, there are no perturbations of long exposures that you need to make when taking pix of very distant objects.
That means that the telescope is on planet Earth, as opposed to a planet in outer space, like the Hubble Telescope, the Planck Telescope, the Chandra Telescope, etc.It is a telescope based on our earth

Because there is no (or very little) atmosphere in space. It is because of our atmosphere that the stars twinkle. This bothers astronomers because when they are looking through a telescope, the see the object twinkling and "moving" in little waves. Thus, they cannot make out details. If there is no atmosphere, there is no twinkling and there is no problem!
If the telescope were placed in space (like hubble) the images would be greatly improved due to the lack of both atmosphere and ambient light, such as streetlights. The lack of atmosphere means that the light from distant objects need not travel through turbulent gases found in the atmosphere. this would eliminate the 'twinkling' of stars, and the lack of ambient light would result in much greater detail in the image.

so it can gather more energy off the sun and store it in the extra panels

To view any distant object in space you need a basic $150 telescope.
