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.

the man-made construct of "time" is a measure of several factors done for societal organization. make no mistake, though. a man-made measure is not insignificant, for "time" is passing. causes and effects. histories. we are constantly moving, and can never go back.  the earth's rotation today is not the same as the one tomorrow. our bodies are growing. our bodies are decaying. things are moving, things are changing, evolving, happening. time, the concept of it, is not an illusion. we will never stop progressing. time is progression.

i have had several friends who have cut themselves. i have almost done it, but more out of curiosity towards how it might feel- for empathic or sympathetic reasons. in a deluded way, i think that it is. a cry for attention. but i don't think that is a bad thing. human beings depend on social interaction. we are social creatures. by cutting, putting a physical show of emotional hurt, it's somewhat of a call for help. it's like crying through blood, something far more serious, much like the pain that leads someone there. cutting itself is very dangerous and terrifying for the people that love the cutter. and this is another reason i think cutting is a cry for help- cutters know that. they know the attention that they'll get, the backlash, the possible hate or obsession others will get over them if their cuts are seen.  but they do it anyway. i think if someone were truly hurting and didn't want anybody to know, they'd just suffer in silence, welling within themselves until they go insane. or show their pain through subtle actions.  y'know. the whole "the saddest people are the happiest" thing.
