Science Daily:

A NASA spacecraft has sent pictures showing itself in good condition after making the first successful landing in a polar region of Mars.

The images from NASA's Mars Phoenix Lander also provided a glimpse of the flat valley floor expected to have water-rich permafrost within reach of the lander's robotic arm. The landing ends a 422-million-mile journey from Earth and begins a three-month mission that will use instruments to taste and sniff the northern polar site's soil and ice.

"We see the lack of rocks that we expected, we see the polygons that we saw from space, we don't see ice on the surface, but we think we will see it beneath the surface. It looks great to me," said Peter Smith of the University of Arizona, Tucson, principal investigator for the Phoenix mission.[..]

"Seeing these images after a successful landing reaffirmed the thorough work over the past five years by a great team," said Phoenix Project Manager Barry Goldstein of JPL. A key milestone still ahead is the first use of the lander's 7.7-foot-long robotic arm, not planned before Tuesday.

"Only five of our planet's 11 previous attempts to land on the Red Planet have succeeded. In exploring the universe, we accept some risk in exchange for the potential of great scientific rewards," said Ed Weiler, NASA associate administrator for the Science Mission Directorate, Washington.

Phoenix carries science instruments to assess whether ice just below the surface ever thaws and whether some chemical ingredients of life are preserved in the icy soil. These are key questions in evaluating whether the environment has ever been favorable for microbial life. Phoenix will also study other aspects of the soil and atmosphere with instrument capabilities never before used on Mars. Canada supplied the lander's weather station.
