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.

JPL, 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 in Denver, Colorado.
