This test image from an engineering model of NASA's InSight lander shows part of the lander's robotic arm and the simulated Martian ground at a testbed at NASA's Jet Propulsion Laboratory in Pasadena, California. The testbed aims to mimic the environment InSight will encounter at Mars so engineers can prepare for the spacecraft operations to come. This image is expected to be similar to the raw or unprocessed images that InSight will send back to Earth. It was taken by the instrument deployment camera attached to InSight's robotic arm.

NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages InSight for NASA's Science Mission Directorate in Washington. InSight is part of NASA's Discovery Program, managed by the agency's Marshall Space Flight Center in Huntsville, Alabama. The InSight spacecraft was built and tested by Lockheed Martin Space.
