Mission to look inside mars

Yesterday, on November 26, a 1,340-pound parcel hurtled through the Martian atmosphere at 12,300 miles per hour. About six minutes later, when the InSight rover landed, it started the slow and careful process of setting up a fleet of scientific instruments, including a probe designed to burrow 16 feet into the planet to take its temperature. Unlike space and surface-based rovers and orbiters, InSight will give us our first good readings of Mars’s insides. Its ability to track the flow of heat from the interior of the planet toward the surface will help figure out where Mars’s volcanoes came from, and the rover’s seismometer will even measure Marsquakes and meteorite impacts.
