because it can

The Pioneer space probes are a series of unmanned space missions sent out by the United States for the purpose of planetary exploration.
Mounts vary in complexity. A simple mount has the purpose of holding the telescope steady. Fancier mounts can have built in motor drives and even computers to find and track stars as they move across the sky.
The Dobsonian telescope was designed with a large objective diameter to observe very faint deep sky objects. It was originally designed from readily available components to provide a large yet still portable low-cost option for telescope users.
The Arecibo radio telescope is the largest radiotelescope in the world. It is suspended in a valley in the Puerto Rican mountains.
The Hubble Space Telescope it used to take pictures of distant objects in space.

To see if rockopper is coming.

He built the telescope because he saw his children play with lenses and he got the idea of making it
Launched on April 24th 1990 the purpose of the Hubble space telescope is so astronauts and astronomers and even the public can discover new images of our Galaxy and other Galaxy's and other planets
The telescope's purpose is for scientists to be able to look into space and see what stars are made of and what the cycle of stars is. Some telescopes are public and anyone can look through them. But others are only for scientists. The telescope was invented by Galileo Galilei. You can see his finger in his very own museum! :0)

Gathering and focusing light from distant objects.

The NIRC-2 feature of the Keck telescope in Hawaii is used for that purpose, though i don't think it is the only one.
