Phoenix has photographed several dust devils dancing across the arctic plain this week and sensed a dip in air pressure as one passed near the lander.
The next soil sample that Phoenix will deliver to its deck instruments will go to the fourth of the four cells of Phoenix's wet chemistry laboratory, according to the Phoenix team's current plans.
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.
