NASA Phoenix Mars Lander Confirms Frozen Water

"It is with great pride and a lot of joy that I announce today that we have found proof that this hard bright material is really water ice and not some other substance," said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson, during a Friday news briefing to announce the confirmation of water ice.

NASA's Phoenix Mars Lander Delivers Soil Sample to Microscope

TUCSON, Ariz. - New observations from NASA's Phoenix Mars Lander provide the most magnified view ever seen of Martian soil, showing particles clumping together even at the smallest visible scale.

NASA's Phoenix Spacecraft Lands at Martian Arctic Site

PASADENA, Calif. -- NASA's Phoenix spacecraft landed in the northern polar region of Mars Sunday to begin three months of examining a site chosen for its likelihood of having frozen water within reach of the lander's robotic arm.

NASA Spacecraft Confirms Martian Water, Mission Extended

Laboratory tests aboard NASA's Phoenix Mars Lander have identified water in a soil sample. The lander's robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples.

Wilkinson Microwave Anisotropy Probe

The Wilkinson Microwave Anisotropy Probe (WMAP) is a NASA Explorer mission. It has produced a wealth of precise and accurate cosmological information. WMAP produced the first full-sky map of the microwave sky with a resolution of under a degree.
