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 solar s 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, Earth about every 97 minutes.
Imagine 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.
Hubble Space Telescope s everything onto optical computer disks. These provide a resource for current and future astronomers. One day's worth of observations would fill an encyclopedia.
When 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.
