TUCSON, Ariz. --NASA's Phoenix Mars Lander's robotic arm collected a more than adequate amount of icy soil for baking in one of the lander's ovens but will need to adjust how it delivers samples.

Engineers determined the rasping and scraping activity collected a total of 3 cubic centimeters of icy soil, more than enough to fill the tiny oven cell of the Thermal and Evolved-Gas Analyzer, or TEGA. However, images returned from the lander Saturday morning show that much of the soil remained lodged in the robotic arm's scoop after the attempt to deliver the sample to the TEGA.
