This full-resolution image from NASA's Curiosity shows the turret of tools at the end of the rover's extended robotic arm on Aug. 20, 2012. The Navigation Camera captured this view.
NASA's Mars rover Curiosity extended its robotic arm on Aug. 20, 2012, for the first time on Mars and used its Navigation Camera (Navcam) to capture this view of the extended arm.
Test operators in a clean room at NASA's Jet Propulsion Laboratory monitor some of the first motions by the robotic arm on the Mars rover Curiosity after installation in August 2010. The arm is shown in a partially extended position.
Testing of the robotic arm on NASA's Mars rover Curiosity on Sept. 3, 2010, included movements of the arm while the rover was on a table tilted to 20 degrees to simulate a sloped surface on Mars.
In this image, engineers from NASA's Jet Propulsion Laboratory test and 'flex' Curiosity's robotic arm and tools. A video can be viewed at the Photojournal.
