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

Before its sudden shattering, numerous meltwater ponds riddled Antarctic ice shelf Larsen B. They are seen in this 2002 satellite image as a matrix of aquamarine spots. Scientists believe that the ponds hydrofractured the kilometer-thick ice shelf, causing its swift destruction. Credit: NASA Earth Observatory
