There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

This bomb sag on the surface of Mars was created during a volcanic blast approximately 3.5 billion years ago. Assistant Professor Josef Dufek has replicated the sag in his lab while studying the possibility of water and atmospheric conditions of early Mars. Courtesy: NASA/JPL
