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

It's an established fact that Mars was once a warmer and wetter place, with liquid water covering much of its surface. Between 4.2 and 3.7 billion years ago, the planet lost its atmosphere, which caused most of its surface water to disappear. But according to a new study led by the U.S. Geological Survey, erosion on the surface of Mars has revealed abundant deposits of water ice. James Wray, an associate professor in the School of Earth and Atmospheric Sciences, contributed to the study, as did Lujendra Ojha, a former Tech researcher who led the 2015 study offering evidence of flowing water on Mars. Ojha is now at Johns Hopkins University.
