Unknown Problem Interrupts Mars Lander's Task
from the San Francisco Examiner
PHOENIX (Associated Press) - The first sample of Martian dirt dumped onto the opening of the Phoenix lander's tiny testing oven failed to reach the instrument and scientists said Saturday they will devote a few days to trying to determine the cause.
Photos released by the University of Arizona team overseeing the mission showed a scoopful of dirt sitting on and around the open oven door after being dumped by the craft's 8-foot robot arm.
But none of it made it past a screen and into the tiny chamber, one of eight on the craft designed to heat soil and test gasses for signs of water or organic compounds that could be building blocks for life.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
