NASA's InSight mission tests an engineering version of the spacecraft's robotic arm in a Mars-like environment at NASA's Jet Propulsion Laboratory. The five-fingered grapple on the end of the robotic arm is lifting up the Wind and Thermal Shield, a protective covering for InSight's seismometer. The test is being conducted under reddish "Mars lighting" to simulate activities on the Red Planet.
