|This view shows the partial opening of doors to one of the ovens of the Thermal and Evolved-Gas Analyzer. Near the center of the image, the partial opening of a pair of doors reveals a screen over the opening where a soil sample will be delivered. The doors are 10 centimeters (4 inches) long. The opening is 4 centimeters (1.5 inches) wide. A soil sample could be delivered into the oven through the partially opened doors. Credit: NASA/JPL-Caltech of Arizona.
