Hubble Space Telescope
NASA and ESA space telescope (launched 1990) / From Wikipedia, the free encyclopedia
Hubble Space Telescope (HST) is the first big optical space observatory telescope. Being above the atmosphere means it can see the sky more clearly than a telescope on the ground. The atmosphere blurs starlight before it reaches Earth. Named after the astronomer Edwin Hubble, the Hubble Space Telescope can observe 24 hours a day. The main mirror is 94.5 inches (2.4 meters) across. The telescope can take pictures of things so far away it would be nearly impossible to see them from anywhere else.

It was made by both NASA and the ESA working together. It is 600 km in space and was launched on April 24, 1990. Like other things in low Earth orbit it travels at 5 miles (10 km) per second. If you were going this speed on Earth, you would be able to get from New York to San Francisco in 10 minutes. This speed creates difficulty in scheduling observations.[1]
The Hubble itself is the size of a large school bus, but still small enough to fit inside the cargo bay of a Space Shuttle. It was repaired in 1993 due to problems in the picture quality.
