Ground controllers were waiting to know how Phoenix fared last night, when an orbiting Mars probe passes over the landing site and relays the data to Earth. (article 5)
After taking the initial sample, Phoenix will spend the rest of the mission clawing through layers of soil to reach ice that is believed to be buried inches to a foot below the surface. (article 5)
Its landing site is in a region where NASA's orbiting Mars Odyssey spacecraft has detected gamma-ray and neutron signatures suggesting a significant amount of hydrogen - thought to be a constituent of frozen water - near the surface. (article 3)
