Perhaps that notion explains NASA's nickname for the rock in  the middle of this picture: Winkies.  This snapshot was taken by the lander's Surface Stereo Imager camera on  Sol 151 of the mission (October 27, 2008), and is among the last from  the lander before its final communication about a week later, on  November 2, 2008.  In the foreground of the false color image is a rock with the less  winsome name of Quadlings. Temperature readings on Sol 151 were  bracing--a daytime high of minus 50 degrees Fahrenheit and an overnight  low of minus 128F. <img src="http://i.i.com.com/cnwk.1d/i/tim//2010/01/15/PhoenixWinkies_440x330.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Using data from the lander's lidar system, NASA produced this graphic  profile of a Martian cloud spotted on Sol 99 (September 3, 2008). Says  NASA, "The vertical streaks at the base of the cloud on the right of the  image show ice crystals falling from the cloud, similar to snow.  The streaks are curved, as the winds are faster at about 3 kilometers  (almost 2 miles) than at higher altitudes. Scientists are able to  determine that the snow is water-based and not carbon dioxide snow,  since temperatures on Mars are currently too warm to support the  latter."  <img src="http://i.i.com.com/cnwk.1d/i/tim//2010/01/15/PhoenixCloud_440x330.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> This composite view combines more than 500 images taken by the lander's  Surface Stereo Imager camera, providing a view of the Phoenix craft from  above.<img src="http://i.i.com.com/cnwk.1d/i/tim//2010/01/14/297716main_polar_AGU_516-387_440x330.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />This is the lander's Thermal and Electrical Conductivity Probe.  Measurements taken by the TECP helped researchers determine that water  was exchanged between soil and atmosphere. <img src="http://i.i.com.com/cnwk.1d/i/tim//2010/01/15/PhoenixTECP_440x330.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />After digging into the Martian soil and collecting samples, Phoenix  placed the soil onto the Thermal and Evolved-Gas Analyzer, seen in the  center of this mosaic of images. On the left is an instrument used for  microscopy, electrochemistry, and conductivity analysis.  <img src="http://i.i.com.com/cnwk.1d/i/tim//2010/01/14/365052main_phx17067-516_440x330.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />In this mosaic of images taken by the lander's camera, we can see  several trenches dug by Phoenix to analyze the history of the region. <img src="http://i.i.com.com/cnwk.1d/i/tim//2010/01/14/365048main_phx17062-516_440x330.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />This shadow-enhanced false color image, taken a week earlier, shows the  "Snow White" trench, on the eastern end of Phoenix's digging area. <img src="http://i.i.com.com/cnwk.1d/i/tim//2010/01/15/PhoenixSnowWhite_440x330.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></blockquote>
