The USGS Flagstaff node of the Planetary Data System in conjunction with Malin Space Science Systems is making the MGS aerobraking phase image set available to scientists and the general public. This is one of the primary repositories of publicly released MGS images. Additional image enhancements will be added to the system as they become available.

The MOC images are available courtesy of the Flagstaff office of the U.S. Geological Survey.



We are pleased to announce an updated release of Mars Global Surveyor MOC Image data through the internet services of the Planetary Data System.

The following data are available:

This site allows access to the raw image data plus full and reduced resolution JPEG versions of the MOC images and "context" JPEG images created from Viking data. We are experiencing a high volume of traffic to the site, so please be patient.

Note that this is a prototype site that will continue to grow and evolve. We are open to any feedback you may have. Many of you have already given us some excellent feedback in terms of possible improvements to the site and we are currently working to implement some of those improvements, but are adding new data in the current site format in order to provide the quickest possible release of the data.

The archives of raw image data were created by Malin Space Science Systems, with web development work performed by the Planetary Data System Imaging Node at the U. S. Geological Survey in Flagstaff, Arizona. Please contact me if you have any problems or questions about the site.
