Boffins at NASA's JPL and the German Aerospace Center (DLR) have come up with a plan to save the stricken Mars InSight probe.

As a reminder, the lander's self-hammering probe, aka the mole, is a key part of the Mars lander's science payload and is designed to record the amount of heat escaping from the interior of the red planet. Named the Heat Flow and Physical Properties Package (HP3), the multi-national instrument was plucked from the deck of the lander back in February by InSight's robot arm and deposited some distance away.
