Curiosity's Robotic Arm Bent at Nearly a 90-degree Angle

In this image, the robotic arm for the Mars Science Laboratory is bent at nearly a 90-degree angle. The robotic arm is undergoing testing in a laboratory at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The arm and tools will reach out and test martian rocks and soil. This arm is identical to the flight hardware that will actually be attached to Curiosity.
