An engineering version of the robotic arm on NASA's InSight mission lifts the engineering version of the Heat Flow and Physical Properties Probe (HP3) at NASA's Jet Propulsion Laboratory. This test was conducted by InSight team members in a Mars-like environment, including reddish lighting, to simulate conditions InSight will encounter on the Red Planet. The orange tape-like tail behind HP3 is a tether that connects the HP3 support structure to the instrument's back-end electronics box on the lander.
