 NASA's '''Phoenix''' mission was a robotic mission, the first lander in NASA's "Scout class".  The lander landed in Mars' north polar region on May 25th 2008, and the scientific package aimed to answer the questions:
-# Can the Martian arctic support life?
+#Can the Martian arctic support life?
-# What is the history of water at the landing site?
+#What is the history of water at the landing site?
-# How is the Martian climate affected by polar dynamics?
+#How is the Martian climate affected by polar dynamics?
 The mission name derives from several components built previously for cancelled missions, including 2001's Mars Surveyor lander.
-The mission was of considerable interest to planners of human missions to Mars, as many practical mission designs assume the availability of easily-extractable water for fuel production and industrial processes. The polar regions were expected to be the most likely places to find [[water|water ice]].

 Phoenix was launched on 4th August 2007 on a [[Delta II]] 7925 rocket, and the scheduled landing on Mars on 25th May 2008 was successful.  The landing site was the ice-capped northern polar region in the Green Valley of Vastitas Borealis.<ref>https://www.webcitation.org/5W4NeGhno?url=http://phoenix.lpl.arizona.edu/</ref>
-Although the primary mission was expected to last around 90 [[sol]]s, the lander lasted much longer. The last transmission was received on November 2<sup>nd</sup>, 2008 by the project team.

 Chemicals measured in the samples were chloride, bicarbonate, magnesium, sodium, potassium, calcium, and sulfate.  Further data analysis indicated that the soil contains soluble sulfate (SO<sub>3</sub>) at a minimum of 1.1% and provided a refined formulation of the soil.<ref>Kounaves, Samuel P; Hecht, Michael H; Kapit, Jason; Quinn, Richard C; Catling, David C; Clark, Benton C; Ming, Douglas W; Gospodinova, Kalina; Hredzak, Patricia; McElhoney, Kyle; Shusterman, Jennifer (2010).
