Want this question answered?
The Hubble Telescope weighs 24,500 pounds.
The problem with ground based telescopes is that the atmosphere distorts images, The Hubble space telescope is above the atmosphere and therefore can view with much better clarity.
The cost at launch in 1990 was 1.5 billion US-$.
Edwin Hubble invented a simple classification system for galaxies. The Hubble Space Telescope was named after him for his discoveries in astronomy.
It was actually 1.5 billion dollars. However, first images came back from the Hubble blurred, due to a faulty mirror. This was a big and even dangerous job to fix, and on top of that, it brought the total cost up to around $6 Billion USD. Ouch.
the hubble space telescope cost 1.5 million dollars

It's much more powerful
1.5 billion US-$ at the launch in 1990.
They use many types of telescopes. You can probably pick up the cheaper ones for as little as $25,000. The Hubble Space Telescope cost $1,500,000,000 ($1.5 billion) just to build.
He doesnt travel.. The Hubble telescope is stationairy and only in space to bypass the atmosphere. The Hubble telescope maginfies so much, that if you are beneath the atmosphere, you get a blurry image. Like looking through a dirty window. So they shot it in space. Beyond the "dirty window".

It says 1.2 billion in this website but i'm not so sure........
Nothing will "replace" the Hubble Space Telescope. However, a couple of new space telescopes are already in space, and another much more powerful one, the Webb Space Telescope, is under construction and should be launched in 2014.
The Hubble telescope is in space so it doesn't have a problem with atmospheric distortion. Therefore The Hubble telescope get's a much clearer picture than any normal land telescope which gets a less clear a picture because of water vapour and diffraction of light.
The main difference is that it is in orbit, above the atmosphere of the earth. This means that it can achieve a much better picture, since the light from the object in space wont be distorted by the atmosphere and its fluctuations. It means that the Hubble telescope can get away with using a much higher magnification.
