A fork-like conductivity probe has sensed humidity rising and falling beside Phoenix, but when stuck into the ground, its measurements so far indicate soil that is thoroughly and perplexingly dry.
Scientists have begun to analyze a sample of soil delivered to NASA's Phoenix Mars Lander's wet chemistry experiment from the deepest trench dug so far in the Martian arctic plains.
NASA's Phoenix Mars Lander, having completed its 90-day primary mission, is continuing its science collection activities.
The next sample of Martian soil being grabbed for analysis is coming from a trench about three times deeper than any other trench NASA's Phoenix Mars Lander has dug.
Phoenix has scooped up a soil sample from an intermediate depth between the ground surface and a subsurface icy layer.
05.09.08 - When NASA's Phoenix Mars Lander descends to the surface of the Red Planet on May 25, few will be watching as closely as those who have spent years planning, analyzing and conducting tests to prepare for the dramatic and nerve-wracking event.
08.03.07 - One of the many critical aspects of the Phoenix mission will be getting the spacecraft safely through Mars' atmosphere and down to the surface.
06.29.07 - Lander will dig for clues to more red planet mysteries.
