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

James WrayA research team didn't expect to find 130 volcanoes deep within Mars' Valles Marineris, the solar system's longest canyon at 2,500 miles. Mars' volcanic regions are east of the canyon, so that was one surprise detailed in a new study from the team, which includes James Wray, assistant professor in the School of Earth and Atmospheric Sciences. The other surprise? The Valles volcanoes' ages are estimated to be about 200-400 million years old, which is fairly young when you consider that the Red Planet's other volcanoes are estimated to be approximately 3.5 billion years old.
