Testing How InSight’s Arm Will Push on Mars
![In a JPL lab, a replica of NASA InSight's robotic arm presses with its scoop on crushed garnet near a replica of the spacecraft's self-hammering "mole." Engineers believe pressing like this on Martian soil may help the mole dig by increasing friction of the surrounding soil.](https://science.nasa.gov/wp-content/uploads/2024/03/22516_PIA23276-16.jpg?w=4096&format=jpeg)
