Mars is a cold desert planet in universe having no water .In martian Artic of mars ,water ice lurks are just below the ground level.The Phoenix lander targets this circumpolar region using a robotic arm to dig through the protective top soil layer to the water ice below and ultimately, to bring both soil and water ice to the lander platform for sophisticated scientific analysis.
Phoenix will be the first mission to return data from either polar region providing an important contribution to the overall Mars science strategy "Follow the Water" and will be instrumental in achieving the four science goals of NASA's long-term Mars Exploration Program.
--Determine whether Life ever arose on Mars 
--Characterize the Climate of Mars
--Characterize the Geology of Mars
--Prepare for Human Exploration
The Phoenix Mission has two bold objectives to support these goals, which are to (1) study the history of water in the Martian arctic and (2) search for evidence of a habitable zone and assess the biological potential of the ice-soil boundary.
