The Jet Propulsion Laboratory home page describes the Pasadena, California, research laboratory's ongoing work in space exploration. The site offers news about the lab (including news of the Galileo spacecraft), online tours, technology transfer, and image and information archives. A special feature is a guided tour of the solar system's planets, asteroids and comets. There is a section describing the basics of space flight, including a glossary of terms related to space and Earth. Connections are available to the NASA home page and the California Institute of Technology, which administers the laboratory.
