The Amazing Hubble
The Amazing Hubble
In the history of latest astronomy, there is probably no one greater leap forward than the building and launch of the space telescope known as the Hubble. While NASA has had many ups and downs, the launch and continued operation of the Hubble space telescope probably ranks next to the moon landings and the development of the Space Shuttle as one of the greatest space exploration accomplishments of the last hundred years.
An amazing piece of astronomy trivia that few people know is that in truth, only about ten percent of the universe is visible using conventional methods of practice. For that reason, the Hubble really was a walloping leap forward. That is for the very simple reason that the Hubble can operate outside of the atmosphere of Earth. Operose to build significant space exploration via telescopes from the terrestrial surface of planet Earth is very difficult. That very thing that keeps us alive, our own Earth’s atmosphere presents a serious distraction from being able to see deeper and further into space.
The Hubble space telescope was named after the great scientist and visionary Edward Hubble who discovered that the universe was expanding which was explained by what is now known in science as Hubble’s Law. To truly get a feel for the amazing accomplishment that was achieved with the launch of the Hubble telescope, spend some time on Nasa’s web site dedicated to the project at http://hubble.nasa.gov. There are also a number of sites where you can enjoy some exquisite pictures from the Hubble including http://heritage.stsci.edu/ and http://www.stsci.edu/ftp/science/hdf/hdf.html.
It’s hard to believe how long the Hubble has been orbiting creation and sending back amazing video and pictures of what de facto is discovering in space. But the Hubble was actually initially launched on April 25th 1990. It was the peak of literally decades of research and construction which began in 1977. Expectations were high as the orbiting telescope was put in place again actually began to function as live was designed to do.
All was not always perfect with the telescope and the early pictures were disappointing. After some study NASA discovered that the reason for the primitive failures was the curvatures of particular of the main lenses of the orbiting telescope.
We probably could never have kept this intricate piece of equipment operational as well as we have had we not had the Space Shuttle program to give us a tool to implement repairs and improvements to the Hubble. In 1993 a new lens was installed on the Hubble which corrected the problem of exemplify resolution that was noted in the early operation of the telescope.
Two other repair and upgrade mission keep been made to the Hubble since it launched, both of them in 1997 to upgrade older equipment and to retrofit the telescope to extend its useful life through 2010. It’s pretty amazing to think that this technical and mechanical marvel has been operating now in that ten years kiss goodbye maintenance. We can be assured that plans are in the works for NASA to upgrade or replace parts on the Hubble to extend its useful life even further as that 2010 time frame draws closer.
It is hard to imagine the the latest of astronomy or the natural quest for greater knowledge of our universe without the Hubble. While many times those who would not fund space outing have tried to framework funding for the Hubble, the agility of this telescope is just too important to astronomers and to the scientific well being of humanity and our planet not to continue to use the Hubble, or its next natural successor. We will always need to obtain a set of eyes in the sky to watch the universe and discover more of its mysteries.
