According to a newsletter sent out by the National Aeronautics and Space Administration (NASA), the purpose of the Hubble Space Telescope was, and is, to gather light from cosmic objects so scientists can better understand the universe around us. Up until the deployment of the Hubble Space Telescope, all telescopes were Earth based and had the disadvantage of having to peer at the stars through the Earth’s atmosphere. The Earth’s atmosphere provides a large amount of distortion when viewing very far objects, like space, through a telescope. Placing a telescope in space eliminates the distortion and provides images that are significantly clearer and in turn, easier to examine. The Hubble Space Telescopes six different science instruments …show more content…
The fourth important instrument is the Near Infrared Camera and Multi-Object Spectrometer, which is basically Hubble’s heat reader. It is very sensitive to infrared light which makes it useful for observing objects tainted by gases and dust. It is also used to peer into the deepest parts of space. The fifth important instrument is the Space Telescope Imaging Spectrograph, which is a utility instrument that separates the light from the cosmos into its component colors. It is also used to study black holes, the composition of galaxies, and the atmosphere of planets around all stars. The sixth and final important instrument is called the Fine Guidance Sensors, which target devices that lock on to “guide stars” and measure their positions in relation to the objects being viewed. The sensors also perform celestial measurements.

The Hubble Space Telescope is powered by solar cells which are solid-state electrical devices that convert the energy of light directly into electricity by an effect called the Photovoltaic effect. When many solar cells are put together they are called solar modules which can also capture energy from sunlight. When many modules are placed together it is called a solar panel. Hubble had many problems finding funding for the telescope. The U.S. Congress questioned the proposed original budget, as it was
