Descrizione:
Phoenix landed near Mars' north pole to study the water ice found close to the surface there. Its arm dug trenches into the soil and delivered samples to sophisticated chemical analysis instruments. The mission ended when winter temperatures and cloud cover led to depletion of solar power, which was expected. The mission was declared concluded on November 10, 2008, after engineers we unable to establish contact with the lander. After unsuccessful attempts to contact the lander with the Mars Odyssey orbiter up to and past the martian summer solstice on May 12, 2010, JPL declared the lander to be dead. The mission was successful, completing all planned science experiments and observations.
