Editor's Note: This image is one of a series showing engineering technology at NASA's Marshall Space Flight Center in Huntsville, Ala.

Caption: From left, Dan Dumbacher, director of Marshall's Engineering Directorate, gets a hands-on lesson about the directorate's newest piece of equipment. Conducting the demonstration is Bob Carter, a welding engineer in the Materials and Processes Laboratory. This robotic weld tool -- the largest friction stir weld tool in the country -- will be used in the design and construction of the Ares I upper stage.
