How Satellites Work
"Start your exploration by clicking on the large title image How Satellites Work. "Man-made satellites circle the Earth in many ways including polar and geostationary orbits." A satellite in a polar orbit travels over the North and South Poles at a height ranging from several hundred miles to several thousand miles above Earth. A satellite in a high-altitude, geostationary orbit (also known as geosynchronous) circles the earth once every twenty-four hours, the same amount of time it takes for the Earth to spin on its axis. To maintain this rotation, a geostationary satellite must travel exactly 22,237 miles above the Earth’s equator."

How Stuff Works: Hubble Space Telescope
"Like any telescope, the Hubble Space Telescope (HST) has a long tube that is open at one end.It has mirrors to gather and bring the light to a focus where its ’eyes’ are located. The HST has several types of ’eyes’ in the form of various instruments. Just like some animals can see varioustypes of light, such as ultraviolet light (e.g. insects) or visible light (e.g. humans), the HST mustalso be able to see the various types of light raining down from the heavens. How Stuff Workspresents an outstanding seven-page history of the Hubble, a look inside the telescope, and anexplanation of how it works."

Great Balls of Fire
"Tom Gehrels works the graveyard shift at an observatory in southern Arizona, searching for what he estimates are ""1,700 potential Earth-killers in outer space. At this point only a small percentage of these rogue asteroids have been found by skywatchers such as himself (together with teammates he has identified 160 so far)."" Learn about the possibility of a catastrophic asteroid impact at this Discovery.com site, and don’t miss the interactive quiz titled ""Launch a Fireball."" "

Google News: Mars Exploration
"Because traditional search engines takes days or weeks to add new sites, the best way to track a breaking news story is through the wire services. And Google’s beta (which means it is still being tested) News site is one of the best. This link will display news stories ""culled from approximately 4,500 news sources worldwide"" and sorted by relevance. To receive Mars Exploration e-mail alerts either daily or in real time, click on News Alerts in the left hand menu."

Girl Scouts Blastoff
"Women have played an important role in space exploration. In 1963, Valentina Tereshkova of the Soviet Union became the first woman to travel in space, orbiting the Earth for over 70 hours. Twenty years later, the American physicist Sally Ride became the first American woman to travel in space. She performed experiments while orbiting the earth in the Space Shuttle Challenger. Written for Girl Scouts, this site adds a women’s perspective to the history of rocketry. In addition to the history lesson and rocket science basics, this site describes how to launch a hobby- store model rocket with your troop or family."
