InSight prepares to take Mars` temperature
(PHYSorg.com Space & Earth)

NASA`s InSight lander has placed its second instrument on the Martian surface. New images confirm that the Heat Flow and Physical Properties Package, or HP3, was successfully deployed on Feb. 12 about 3 feet (1 meter) from InSight`s seismometer, which the lander recently covered with a protective shield. HP3 measures heat moving through Mars` subsurface and can help scientists figure out how much energy it takes to build a rocky world.
