Voyager
at 90 AU ... and beyond
The Voyager journey of discovery continues. After traveling
through space for more than 27 years, Voyager 1 has set
a new milestone. On November 5, 2003, the spacecraft reached
90 astronomical units (AU) from the Sun. 90 AU is the equivalent
of about 8.4 billion miles or 13.5 billion kilometers. It
is the only spacecraft to have made measurements in the
solar wind from such a great distance from the source of
the dynamic solar environment.
Recent
observations indicate that Voyager 1 is in a region unlike
any encountered in its 26 years of exploration. These observations
and what they may infer about the approach to the termination
shock were the subject of a NASA Space Science Update (SSU)
on November 5, 2003. For more details, go

The
Greatest Space Adventurer
The Voyager mission, now in its 26th year, continues its
quest to push the bounds of space exploration. The twin
Voyager 1 and 2 spacecraft opened new vistas in space by
greatly expanding our knowledge of Jupiter and Saturn. Voyager
2 then extended the planetary adventure when it flew by
Uranus and Neptune, becoming the only spacecraft ever to
visit these worlds.
Voyager
1, now the most distant human-made object in the universe,
and Voyager 2, close on its
heels, continue their ground-breaking journey with their
current mission to study the region in space where the Sun's
influence ends and the dark recesses of interstellar space
begin. More about the interstellar
