"We'd like to introduce our newest guest bloggerthe Phoenix Mars Lander. With a successful mission starting to wind down as a cold winter rapidly descends upon its landing site in the Martian arctic, we're pretty happy that Phoenix, (already a prolific Twitterer) has agreed to look back with us on its amazing life over the course of its final days on Mars.
Here Phoenix starts with the very beginning of the story. We're pretty sure a spacecraft has never guest-edited a blog before. Enjoy."
