A Window to the Universe Ever since the first civilizations began naming the dots in the sky, mankind has been fascinated by the cosmos and how they work. Telescopes were invented so that people could better view the stars and planets. Eventually, someone had the grand idea to launch one into space. It was named after the famous astronomer Edwin Hubble. Despite the trouble it has given engineers and astronauts since its launch, the Hubble space telescope has led to dozens of scientific breakthroughs and has changed the way humankind sees the universe. The telescope is the culmination of ten years of hard work done by over 10,000 scientists and engineers. It cost 1.5 billion dollars at launch(HubbleSite). Hubble is 13.3 meters long and…show more content…
The astronauts launched into space aboard the shuttle Atlantis in 2009. The troubles began during the first spacewalk. There was one stuck bolt on the door, preventing it from being opened all the way. Eventually it was pried out and the work continued. The astronauts installed a wide field camera and three Remote Sensor Units, or RSUs. In order to install these units, the two space walkers had to go inside the telescope and guide them into position with a stick, being careful not to bump anything. After day one, the exhausted astronauts peeled their space suits off and decided to name the RSUs Moe, Larry, and Curly(DiCaprio). The next few days involved attaching an instrument that would analyze the atmospheres of other planets and replacing the Advanced Camera for Surveys. The camera was not designed for replacement in space, and in order to remove the old one, 32 tiny screws had to be taken out and put back in. Sharp circuit boards had to be avoided so that nobody cut through their gloves. It was a dangerous task, but the last day finally arrived. The astronauts returned Hubble to orbit and came home to celebrate(DiCaprio). Since its launch, Hubble has led to more scientific breakthroughs than one can count. It has revealed the age of the universe to be 13 to 14 billion years. It helped to discover dark energy, which
