An introduction to the technology of the hubble telescope

The images seen through refracting telescopes were not perfect. Nowadays, there are many different types of telescopes astronomers use to study space.

It was soon discovered that if the telescope lenses were further apart, they would show a clearer image.


Lockheed was commissioned to construct and integrate the spacecraft in which the telescope would be housed. This means that you would look straight through the telescope from one lens to the other through to the image you were looking at.

Telescopes began to get really, really long. Space Exploration Introduction to Telescopes Humans have been studying the night sky since the beginning of time. This blurriness is called chromatic aberration.

The first telescopes used to peer into space were refracting telescopes. They were very difficult to move and set up. Congress questioned many aspects of the proposed budget for the telescope and forced cuts in the budget for the planning stages, which at the time consisted of very detailed studies of potential instruments and hardware for the telescope.

They followed the stars and the moon like clockwork. In response to a schedule described as "unsettled and changing daily", NASA postponed the launch date of the telescope until April InNASA established two committees, one to plan the engineering side of the space telescope project, and the other to determine the scientific goals of the mission.

Eventually humans were able to launch telescopes into space that allowed even more detailed looks at objects in space, like the Hubble Space Telescope. These were their calendars. The distance between the lenses is called the focal length.

His telescope had a focal length of feet 48m. To reduce that risk, a nitrogen gas purge was performed before launching the telescope into space.

The art of grinding and polishing glass lenses was slow going in the beginning. Therefore, its mirror needed to be polished to an accuracy of 10 nanometers 0. This type of telescope had a mirror inside that would reflect the image to a focus point. To save money, NASA halted work on the back-up mirror and put the launch date of the telescope back to October As time went on, one theory about the night sky became widely accepted.

Second, a space-based telescope could observe infrared and ultraviolet light, which are strongly absorbed by the atmosphere. Veterans, people who are disabled, or wounded warriors who need assistance with the employment process may contact us at careers stsci.The Telescope: Its History, Technology, and Future 1st Edition Edition.

The Telescope is the ideal introduction to a fascinating instrument that has taught us so much--but that most of us know so little about.

Next we are in space with the Hubble Space Telescope. If you don't know the history of how they screwed up the primary mirror /5(9). May 29,  · The Hubble Space Telescope, or HST, is a unique tool for space exploration and for education.

For more than 18 years, Hubble has peered into the universe, inspiring students of all ages to wonder — to ponder new science questions and to seek answers about the universe. - Introduction The Hubble Space Telescope was a technological marvel that produced images of space from a far distant.

NASA launched it to space on April 24, providing scientists over fifteen years of knowledge, discoveries, and images.

Introduction to Telescopes

Opportunities Introduction The Space Telescope Science Institute (STScI), operated by the Association of Universities for Research in Astronomy (AURA), is a multi-mission science operations center for NASA’s flagship observatories.

May 29,  · Introduction to Hubble. April 14, [image] The Hubble Space Telescope, launched in Aprilis poised for many more years of trailblazing science ranging from Earth's solar system to the edge of the observable universe. The telescope is fulfilling the hopes astronomers have long held.
