NASA's latest Mars probe has gone on a long walk indeed for a drink of water—well, more of a whiff, really. On May 25 Phoenix Mars Lander successfully completed its 10-month, 422-million-mile (679-million-kilometer) journey, alighting near the north pole of the Red Planet for a three-month stay. Using a robotic arm and a series of small ovens, it will scoop up ice thought to lie beneath the surface and take a good sniff of whatever chemicals bake off. This series of images shows Phoenix at work.
