Since it first introduction, telescopes have served mankind a vast deals of researches experiences and discoveries of planets, moons and other intergalactic contents. As we all know telescopes help us to see stars beyond our naked eyes. It becomes a defense mechanism to predict the fall of asteroids or predict movements of celestial bodies.
One powerful telescope that has done many many great things is The Hubble Space telescope. Since it’s launch in 1990, the Hubble Telescope was marked as the most significant advancement of the astronomy field since Galileo’s Telescope. It has been said to cost NASA $2.1 billion to make the telescope. It was said to be more than 14,000 scientific papers was published using the data from this telescope, thus making it the most productive scientific apparatus ever exist. Also, I find it interesting that this telescope has moved more than 3 billion miles along the circular orbit of the Earth.
This year, Hubble is turning 27 years old and some says that Hubble telescope will eventually die due to the pulling gravity force by the Earth. The sun is also heating up the telescope at high temperature and degrading the telescope over times. Hubble Telescope had its last servicing mission in 2009 which was done by spacewalks. It will allow a robotic spacecraft to attach itself on the telescope and guide itself back down into the Earth’s atmosphere at the end of its life.
