Hubble Space Telescope

Hubble Space Telescope - Reviewed by Kidzworld on Dec 27, 2006

NASAs Hubble Space Telescope is one of the most amazing scientific instruments that captures pictures of our universe the human eye would never see.

NASA's Hubble Space Telescope has given us the most spectacular look at the universe. The Hubble telescope has captured many events including a colliding galaxy called "Tadpole." Another picture is a stunning collision between two spiral galaxies called "The Mice." NASA's Hubble Space Telescope has been around since 1990 and is one of the most amazing pieces of scientific equipment in orbit. Here's a look at how Hubble Space Telescope works.

Hubble isn't on NASA's balcony. It's actually "flown" like a spacecraft. Think of a robot or computer in space that only responds to specific instructions from people on the ground. Hubble has communications antennae so astronomers and technicians can tell the telescope what to do and when to do it. Four antennae send and receive info between the telescope and the Flight Operations Team at the Space Telescope Science Institute.

In order for NASA's Hubble Space Telescope to work, it needs electricity. There isn't an extension cord long enough to reach the ground from space, so Hubble runs on sunlight. This makes it the ultimate cordless power tool. On either side of the telescope's tube are two wing-like solar panels which convert sunlight into about 3,000 watts of electricity. That's enough power to light 30 household light bulbs.

Hubble Space Telescope has five instruments that work together, or individually, to provide us with impressive images from the furthest depths of space. Hubble is made up of 3 cameras, spectrographs and guidance sensors. For more info on these instruments, click here.

1Hubble Space Telescope orbits about 600 kilometers above the Earth. It circles the Earth about every 97 minutes.

1Imagine pointing a laser on a dime 200 miles away and then holding it steady for hours or days. That's exactly how sophisticated and precise Hubble's pointing control system is. Once Hubble locks onto an object, sensors check for movement 40 times a second. If something moves, wheels that are constantly on the move change speeds to smoothly bring the telescope back to position.

1Hubble Space Telescope downloads everything onto optical computer disks. These provide a resource for current and future astronomers. One day's worth of observations would fill an encyclopedia.

1When the Hubble telescope was first launched, a mirror had warped so everything was out of focus. Three years later a team was sent up to the telescope and they fixed the problem.

By request of @AwesomeIvysaurGirl34 . I will attempt to follow through as much as I can, but I would love some help from YOU, the reader. I will sometimes (often) suffer from writer's block and disinterest! If you enjoy what I've written, even in this short post, encourage me and give me ideas! It's all appreciated, even criticism. I will post as often as I write. A continuation of "The Man in the Coffee Shop", found in the forums.  A few (a lot) entrees are not included  due to laziness. December 7, 1941 Well, they’ve done it. Japan has bombed Pearl Harbor. I’ve been praying for much of the day for the families of those poor soldiers. I’ve been wondering if perhaps I should join the fight, though I might not have a choice soon enough. Drafting is sure to begin soon, as it won’t be long until Roosevelt declares war. It’s only been… what, three years?... and I feel this war has gone on long enough.   January 1, 1942 Happy New Year! Not very happy for me, though. My draft card came in today. I kind of knew it was inevitable, but… a man can hope, can’t he? Have to go pick up my uniforms now. That’s all for today   January 20, 1942 First day of Boot Camp. Yay… It was already the most exercise of my life. We ran a couple miles (I’ve never ran more than one), and I can tell my commander doesn’t like me. Lieutenant Michaels is his name. Been called out more than once by Michaels in front of everyone, and the food’s awful. But there’s this really cute secretary of his that I couldn’t catch the name of, but I already saw all the other recruits goggling at her. Pathetic, ain’t it? Talked to the guys and half of them are married already. It’s around 9:00, though I should say 2100? I think? Military time is confusing. But, the beds are a bit more comfortable than I expected. Actually, I don’t know what I expected. I don’t know the first thing about war, except a few stories from my grandpapy. He did some pretty amazing stuff back in the Great War. That smear right there is my chuckling and disturbing the pen. It’s just, they said the Great War was the “War to end all wars,” and here we are again. There’s nothing new under the sun, and human nature doesn’t change.
