When NASA’s InSight lander touches down on Mars in November, its handlers already will have had lots of practice operating its cranelike robot arm — thanks to an InSight knockoff sitting in a plot of simulated Martian grit back on Earth.
The Mars-style testbed at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., is the focus of a newly released 360-degree video clip.
JPL’s scientists and engineers use the testbed, set up in a facility known as the In-Situ Instrument Lab, to simulate the terrain in which Mars probes might find themselves.
