TUCSON, Ariz. -- A powered rasp on the back of the robotic armscoop of NASA's Phoenix Mars Lander is being tested for the firsttime on Mars in gathering sample shavings of ice.
The lander has used its arm in recent days to clear away loose soilfrom a subsurface layer of hard-frozen material and create a largeenough area to use the motorized rasp in a trench informally named"Snow White."
The Phoenix team prepared commands early Tuesday for beginning aseries of tests with the rasp later in the day. Engineers andscientists designed the tests to lead up to, in coming days,delivering a sample of icy soil into one of the lander's laboratoryovens.
"While Phoenix was in development, we added the rasp to the roboticarm design specifically to grind into very hard surface ice," saidBarry Goldstein, Phoenix project manager at NASA's Jet PropulsionLaboratory, Pasadena, Calif. "This is the exactly the situation wefind we are facing on Mars, so we believe we have the right toolfor the job. Honeybee Robotics in New York City did a heroic job ofdesigning and delivering the rasp on a very short schedule."
