InSight deploys heat flow package

PIA23046-1041NASA’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. HP3measures heat moving through Mars’ subsurface and can help scientists figure out how much energy it takes to build a rocky world.

Equipped with a self-hammering spike, mole, the instrument will burrow up to 16 feet (5 meters) below the surface, deeper than any previous mission to the Red Planet. For comparison, NASA’s Viking 1 lander scooped 8.6 inches (22 centimeters) down. The agency’s Phoenix lander, a cousin of InSight, scooped 7 inches (18 centimeters) down.

“We’re looking forward to breaking some records on Mars,” said HP3 Principal Investigator Tilman Spohn of the German Aerospace Center (DLR), which provided the heat probe for the InSight mission. “Within a few days, we’ll finally break ground using a part of our instrument we call the mole.” [More at link]
