If it is like the Mars Rovers it will be digging for 90 months.
This one is not a rover unfortunately, it’s gonna just sit there and dig around, has some pretty cool instrumentation onboard. http://phoenix.lpl.arizona.edu/science05.php
It’s an effort involving the University of Arizona.

THE MISSION
The University of Arizona is honored to be the first public university to lead a mission to Mars. The Phoenix Mars Mission, scheduled to land May 25, 2008, is the first in NASA’s “Scout Program.” Scouts are designed to be highly innovative and relatively low-cost complements to major missions being planned as part of the agency’s Mars Exploration Program.
Those things make the Energizer Bunny look weak!
