House Call for Hubble
Space Shuttle Atlantis is scheduled to launch on October 8, 2008 on a mission to service the Hubble Space Telescope. The Hubble, launched in 1990, orbits 350 miles above Earth. It is in need of some repair and upgrades. The first major optical telescope to be placed in space, the Hubble gives us a clear view of the universe. Because it orbits so high, there are no city lights, rain clouds, or pollution to obstruct its view. The Hubble Space Telescope does not travel to stars, planets, or galaxies. It snaps pictures of them as it orbits around Earth at 17,500 miles per hour. Astronomers are using images from Hubble to observe the most distant stars and galaxies, as well as the planets in our own solar system. To view some of the images from Hubble, go to hubblesite.org/gallery/album/star_collection/pr2006033c
In October, seven astronauts will carry equipment, tools, and new instruments on the fifth and final mission to service the telescope. The repairs and upgrades will help extend the life of the Hubble Space Telescope. Once the space shuttle retires in 2010, we will have no way to repair the Hubble.
The eleven day mission will feature five spacewalks. Astronauts will climb outside the space shuttle to work on the space telescope. They will be dressed in special EVA (extra-vehicular activity) suits to keep them safe as they work, traveling 17,500 miles per hour. What is it like to be whizzing around in orbit 350 miles above Earth? To perform your own simulated EVA go to www.discovery.com/stories/science/iss/i_spacewalk.html
