Hubble Space Telescope

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.

I don't believe in hunting for sport. However, hunting for survival, and with due respect for the animal (quickest death you can give)-I have no issue with, nor if you're hunting to eliminate a legitimate threat (ex. rabid coyote).

I never knew you, Never once gazed upon your face, Never heard your voice, the sound of your laughter You never passed me by in the hallways- Or maybe you did, but we wouldn’t remember. I was a freshman, you a senior. A soccer player, while you were in the marching band That October night, when the call went out, All I knew was your name The name of someone who I shared a building with for months, Yet our paths were never to meet. When the school fell silent for many days, When no one spoke a word, the air dense, heavy, I couldn’t share in the pain of your friends, your family Body numb at the sight of your flower-strewn car spot, Limbs frozen, mouth choked as the school came together as one, Flickering candles resisting the bitter bite of the wind. Fly high, brother. For you may be gone, but you are a Thunderbird, and we will never forget.
