Probe From NASA's InSight Lander Burrows Into the Soil of Mars

'The 'mole' aboard NASA's InSight Mars lander has encountered stiff resistance on its first subsurface sojourn beneath the surface of the Red Planet,' reports Space.com:

In a major mission milestone, InSight's Heat Flow and Physical Properties Package (HP3) instrument burrowed underground for the first time on Feb. 28. After 400 hammer blows over the course of four hours, the instrument apparently got between 7 inches and 19.7 inches (18 to 50 centimeters) beneath the red dirt -- but obstacles slowed its progress, mission team members said...
The $850 million InSight lander -- whose name is short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport -- touched down on Nov. 26. The spacecraft aims to map the Red Planet's interior in unprecedented detail. It will do this primarily by characterizing 'marsquakes' and other vibrations with a suite of supersensitive seismometers, which was built by a consortium led by the French space agency CNES; and measuring subsurface heat flow with HP3, which DLR provided.

'I'm digging Mars!' announced NASA's official Twitter feed for the InSight robotic lander, adding 'My self-hammering mole has started burrowing in, and my team is poring over the data...'
