From msnbc online I read that Phoenix did a few test digs this past weekend. Here is a real interesting photo taken of soil inside the scoop. Initial tests will ascertain whether or not the white patches in the upper right are water, CO2 or some form of salt. The actual digs are expected to start later this week, where the 8 foot arm will make a series of trenches looking for water and organic compounds that could be the building blocks of life.
