Hubble Space Telescope
Hubble Space Telescope was deployed from the Space Shuttle Discovery in 1990. Unfortunately the lenses were not working properly until a shuttle team could repair it in 1993. It was modified again in 1997 and once more in 2009. Because the telescope is beyond earth’s atmosphere, it can detect images seven to ten times better than any earth scope. The size of a school bus, the telescope continues to send back amazing images of our universe. Children can check out all the Hubble resources at: http://hubblesite.org/gallery/. NASA has a special site to celebrate Hubble’s birthday: Hubble Birthday. There you can enter your birthday to see what Hubble saw that day!
Magellan fixed inside Atlantis
Atlantis, an American shuttle spacecraft, was launched in 1989. It successfully deployed Magellan, which traveled to Venus to map the planet’s surface. Magellan encountered Venus on August 10, 1990 and began taking high-quality radar images on September 15, 1990. It continued to photograph the planet’s surface, making six complete mapping cycles. Magellan mapped about 98 percent of Venus’s surface. It was commanded to plunge into Venus’s surface, still sending data, on October 13, 1994. Children could learn more at: Magellan.

World Wide Web trial run was first successfully conducted in 1990. The Internet and the World Wide Web are not synonymous. The Internet is the hardware and systems, and the World Wide Web is the data that browsers allow us to exchange. Tim Berners-Lee in 1990 developed Hypertext Transfer Protocol (HTTP), a way for computers to talk to each other. Others developed browsers to make the process easier. The WorldWideWeb, originally its name, allowed the use of the Internet to increase exponentially. Berners-Lee, a British citizen, was knighted for his work in 2004.
