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.

JPL manages InSight for NASA's Science Mission Directorate. InSight is part of NASA's Discovery Program, managed by the agency's Marshall Space Flight Center in Huntsville, Alabama. Lockheed Martin Space in Denver built the InSight spacecraft, including its cruise stage and lander, and supports spacecraft operations for the mission.

A number of European partners, including France's Centre National d'Études Spatiales (CNES) and the German Aerospace Center (DLR), are supporting the InSight mission. CNES and the Institut de Physique du Globe de Paris (IPGP) provided the Seismic Experiment for Interior Structure (SEIS) instrument, with significant contributions from the Max Planck Institute for Solar System Research (MPS) in Germany, the Swiss Institute of Technology (ETH) in Switzerland, Imperial College and Oxford University in the United Kingdom, and JPL. DLR provided the Heat Flow and Physical Properties Package (HP3) instrument, with significant contributions from the Space Research Center (CBK) of the Polish Academy of Sciences and Astronika in Poland. Spain's Centro de Astrobiología (CAB) supplied the wind sensors.
