The robot arm of the Phoenix Mars Lander has successfully deposited a second soil sample into the probe's wet chemistry lab. The first sample contained several water soluble elements. Analysis of the second sample will take place over the next few days.
Scientists are also trying to find a way to get ice into the Lander's lab. They're used the robot arm to dig down to a subsurface layer of ice, and even scraped some off, but so far haven't been able to bring an icy sample into the Phoenix lab system.
