While NASA's InSight spacecraft landed on Mars, thrusters on the bottom of the spacecraft churned up the soil beneath it. This image shows pits that the thrusters excavated. This image was taken Dec. 14, 2018, the 18th Martian day, or sol, of the mission, using the Instrument Deployment Camera on InSight's robotic arm. https://photojournal.jpl.nasa.gov/catalog/PIA23250
