Even though it has now been nearly 20 years since the last Galileo images of Jupiter's moon Io have been taken, many of the images taken of this colorful moon have not gotten wide circulation. This site consists of numerous color composites and mosaics of Io, some are reprocessed versions of the images that were press released, others are only available as raw images on the Galileo PDS site. These images are being made available for the benefit of the community.
This is an ongoing side-project of mine and images are being added and reprocessed all the time. The vast majority of the data used here has been calibrated and processed in ISIS, a spacecraft image processing software package by the Astrogeology Group at USGS-Flagstaff. The resulting processed images are then ported over to Photoshop where they are merged and converted to a format suitable for online viewing (normally PNG). In 2008, I extended this project to New Horizons and Voyager images, though I have had much less success with Voyager images in ISIS than I would have liked.
Another feature on this site are the maps I will be adding for each orbit (and later Voyager and New Horizons). these maps will help show visitors to this website how Io's appearance changed as a result of surface changes (as well as illumination angle changes). Currently, only a few maps are available but more are being added each week.
