The National Aeronautics and Space Administration's Jet Propulsion Laboratory has been making images and data obtained by the Galileo Solid State Imaging (SSI) system available on an ongoing basis for some time (see, for instance, the Scout Report for September 12, 1997). However, for the first time, complete image data from the first nine orbits (G1-G9) have been merged, validated, and made...

The Galileo Spacecraft "has detected a thin carbon dioxide atmosphere on Jupiter's moon Callisto, and has confirmed the existence of carbon dioxide on Callisto's surface." This epiphany is very exciting because it means that all of Jupiter's Galilean moons, Callisto, Europa, Io, and Ganymede, have some form of atmosphere. This site is a news release from the Jet Propulsion Laboratory.

NASA offers these images from the Hubble Space Telescope and the Galileo Project. Simultaneous observations at Hubble and NASA's Infrared Telescope Facility on Mauna Kea, Hawaii have also provided glimpses into Neptune's huge storms and equatorial winds of 900 mph. The site provides a press release, images, and a Quicktime animation.
