The InSight HP Penetrator (Mole) on Mars: Soil Properties Derived from the Penetration Attempts and Related Activities.

Unlabelled: The NASA InSight Lander on Mars includes the Heat Flow and Physical Properties Package HP to measure the surface heat flow of the planet. The package uses temperature sensors that would have been brought to the target depth of 3-5 m by a small penetrator, nicknamed the mole. The mole requiring friction on its hull to balance remaining recoil from its hammer mechanism did not penetrate to the targeted depth.

SEIS: Insight's Seismic Experiment for Internal Structure of Mars.

Unlabelled: By the end of 2018, 42 years after the landing of the two Viking seismometers on Mars, InSight will deploy onto Mars' surface the SEIS (eismic xperiment for nternal tructure) instrument; a six-axes seismometer equipped with both a long-period three-axes Very Broad Band (VBB) instrument and a three-axes short-period (SP) instrument. These six sensors will cover a broad range of the seismic bandwidth, from 0.01 Hz to 50 Hz, with possible extension to longer periods.
