This image of the deck of NASA's InSight lander - where the camera's rectangular calibration target can be seen in the middle - was taken by the Instrument Deployment Camera during the assembly, test and launch operations phase at Lockheed Martin Space, Denver. The Instrument Deployment Camera is attached to the spacecraft's robotic arm.
