NASA's InSight lander took this series of images on Tuesday, March 5, 2019, capturing the moment when Phobos, one of Mars' moons, crossed in front of the Sun and darkened the ground around the lander. The images were taken by InSight's Instrument Deployment Camera (IDC), located on the lander's robotic arm. The images were taken at intervals of about 50 seconds in order to capture the eclipse, which on this day lasted 24.3 seconds. In the lower right corner of the frame, the shadow of the robotic arm can be seen moving to the right before the entire scene darkened during the moment of the eclipse.
