The NASA InSight lander was designed to examine the interior of Mars. The InSight lander originally began working on February, and it is now able to dig due to a strategy change by NASA. The arm of the robot was originally unable to dig because of the rough terrain. NASA's new strategy allowed the InSight lander to dig by placing the arm against the probe, which increases the friction to the point where the lander can dig.
NASA’s new plan still has the lander operating at a slow pace. The lander began to dig on October 8th, and it has dug almost an inch. The lander is attempting to dig to a depth of 16 feet, so the project will take a lengthy amount of time.
