InSight

InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) is a NASA Discovery Program mission that will place a single geophysical lander on Mars to study its deep interior. But InSight is more than a Mars mission. It will answer fundamental questions about the formation of the rocky planets of the inner solar system - including Earth - more than four billion years ago.

By using sophisticated geophysical instruments, InSight will delve deep beneath the surface of Mars, detecting the fingerprints of the processes of terrestrial planet formation, as well as measuring the planet's "vital signs": Its "pulse" (seismology), "temperature" (heat flow probe), and "reflexes" (precision tracking).

The scientific payload consists of two instruments. The seismometer (SEIS), provided by the French CNES, will capture the internal activity of Mars. The Physical Properties Package (HP³), contributed by the German DLR, will measure the planetary heat flow. In addition, the Rotation and Interior Structure Experiment (RISE), led by JPL, will use the spacecraft communication system to provide precise measurements of planetary rotation.

IWF contributes to the investigation of soil mechanical properties, derived from the HP³ penetration.
