This NASA handout image obtained on August 5, 2008 shows a view that combines more than 400 images taken during the first several weeks after NASA's Phoenix Mars Lander as it arrived on an arctic plain at 68.22 degrees north latitude, 234.25 degrees east longitude on Mars. The full-circle panorama in approximately true color shows the polygonal patterning of ground at the landing area, similar to patterns in permafrost areas on Earth. The center of the image is the westward part of the scene. Trenches where Phoenix's robotic arm has been exposing subsurface material are visible in the right half of the image. The spacecraft's meteorology mast, topped by the telltale wind gauge, extends into the sky portion of the panorama. The Phoenix lander's analysis of recent soil samples taken on Mars has found possible traces of perchlorate, a highly oxidizing substance detrimental to life, NASA said on August 4, 2008. Two separate soil samples were analyzed within the last month by two onboard Phoenix instruments, "suggesting one of the soil constituents may be perchlorate," NASA said in a statement stressing the preliminary quality of the tests. "We are committed to following a rigorous scientific process. While we have not completed our process on these soil samples, we have very interesting intermediate results," said Peter Smith, Phoenix's principal investigator at the University of Arizona, Tucson.
