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.

Every day in Australia, 30 people are rescued from drowning. And saving lives is about to get easier. Later this year, during the Southern Hemisphere summer, drones will be used to help rescue stranded swimmers and to spot sharks that might be getting a little too close for comfort.
