Most exciting rocks since the Blueberries (http://cosmoquest.org/forum/showthread.php?33822-Mars-rover-news&highlight=blueberry) and Newberries (http://cosmoquest.org/forum/showthread.php?137977-Opportunity-Nets-New-Nodules&highlight=curiosity).

At one time I quit going to Space.com because my pc did all sorts of funny things there. Not too many problems now, maybe it doesn't like iPhones.
