NASA Space Science Homepage

http://voyager.jpl.nasa.gov

This is the homepage of the Voyager project, which has been running since 1972. The aim of the project was to explore the distant planets and the far reaches of space, sending back information to the scientists on Earth for analysis. There are two Voyager spacecrafts - Voyager 1 and Voyager 2. Both have passed the orbits of our known planets. Voyager 1 is now the most distant human-made object in space. It is a staggering 6.7 billion miles from Earth. It is expected to cross the termination shock - the region that separates the solar wind from interstellar space - in 2002.

This site provides up-to-date information on the progress of the mission, along with photos taken by the two spacecraft on their journeys.
