IMAGE ADVISORY

Images of two of Jupiter’s moons — Io and Europa — taken by NASA’s Galileo spacecraft during encounters late last year
will be unveiled online Monday, March 6, at 9 a.m. Pacific Daylight Time at http://photojournal.jpl.nasa.gov/new .

These are the same images being released by the
University of Arizona, Tucson, and they show volcanic features on Io and the side of Europa that faces Jupiter. Pictures from
the more recent, closest-every flyby of Io on February 22 are
currently being transmitted to Earth and will be processed and
then released in the near future.

Galileo has been orbiting Jupiter and its moons since
December 1995. After its primary mission ended in December 1997, Galileo successfully completed a two-year extended
mission, and it is currently embarking on another extension, called the
Galileo Millennium Mission.

More information about the Galileo mission is available
at http://galileo.jpl.nasa.gov .

JPL manages Galileo for NASA’s Office of Space Science,
Washington, D.C. JPL is a division of the California Institute
of Technology in Pasadena.
