Getting ready for the next Martian visitor!
This image is taken within the region that Mars Phoenix is expected to land on May 25th, one month from today. The whitish areas criss-crossing the landscape here is the seasonal carbon dioxide frost that covers the Martian poles during the winter. Phoenix will represent the first ever landing in a Martian polar region and is expected to yield considerably different results than we have seen from any of the previous landers or rovers.
