NASA's InSight lander is gearing up to help rescue a instrument trapped beneath Mars' surface

NASA is gearing up for a rescue operation that they hope will save a critical instrument on its Mars lander that remains trapped just centimeters below the surface. In March, after less than a year on Mars' surface, NASA's InSight Lander reported that a critical instrument -- a'mole' probe that is designed to burrow into the planet and assess heat emissions -- hit a snag. For several months, the probe, which was meant to bore 16 feet downward, has been trapped just 30 centimeters beneath the planet's surface after less than a month into its burrowing process. A newly devised plan, however, could extricate the probe once and for all. NASA's InSight probe will try to save a critical instrument that is trapped beneath Mars' surface.
